a continuous random variable x is normally distributed with a mean of 0 and a standard deviation of 1. the probability of an observation that lies within the range of -1.0 < x <1.0 is:
a continuous random variable x is normally distributed with a mean of 0 and a standard deviation of 1. the probability of an observation that lies within the range of -1.0 < x <1.0 is 0.6827.
The explanation for normal distribution is described by two parameters, the mean (μ) and the standard deviation (σ).
A continuous random variable X that is normally distributed has the probability density function, (X is a normally distributed variable):
f(x)=1σ√2π×e−12((x−μσ)2)
A normal distribution with a mean of 0 and standard deviation of 1 is called standard normal distribution or Z-distribution. The probability for the standard normal distribution can be found using the standard normal distribution table.
In this case, we have a continuous random variable x which is normally distributed with a mean of 0 and a standard deviation of 1. We are asked to find the probability of an observation that lies within the range of -1.0 < x < 1.0.
In other words, we want to find: P(-1.0 < x < 1.0)
To do this, we need to transform the interval (-1.0, 1.0) to a standard normal distribution as follows:
Z=(X−μ)/σ = (X−0)/1
= X
Next, we use a standard normal distribution table to find the probability for Z as follows:
P(-1.0 < x < 1.0) = P(-1 < Z < 1)
= P(Z < 1) - P(Z < -1)
From the standard normal distribution table,
We have P(Z < 1) = 0.8413 and
P(Z < -1) = 0.1587
Therefore: P(-1.0 < x < 1.0) = 0.8413 - 0.1587
= 0.6827
Thus, the probability of an observation that lies within the range of -1.0 < x < 1.0 is 0.6827.

Question 20
After months of negotiations, Jabu's annual salary was increased by 6. 35% to R330 000. Determine his
previous monthly salary and the monthly increase he will be getting.
Original salary of R20 955. 00, with an increase of R6 545. 00 per month.
[2] Original salary of R25 858. 02, with an increase of R1 641. 98 per month
(3) Original salary of R27500. 00, with an increase of R1 746. 25
per
month.
14] Original salary of R25 858. 02, with an increase of R1 746. 25 per month.
Jabu's Monthly salary is of R27500.00, with an increase of R1 746.25 per month. Jabu's monthly increase is R1 746.25. The correct answer is option 3.
To find Jabu's previous monthly salary, we can use the formula:
Previous monthly salary = (Annual salary / 12)
Since Jabu's new annual salary is R330 000, his previous annual salary would be:
Previous annual salary = (New annual salary / 1.0635) = (R330 000 / 1.0635) = R310 020.10
Therefore, Jabu's previous monthly salary would be:
Previous monthly salary = (Previous annual salary / 12) = (R310 020.10 / 12) = R25 835.01
To find the monthly increase, we can subtract Jabu's previous monthly salary from his new monthly salary:
Monthly increase = (New monthly salary - Previous monthly salary) = (R27 618.38 - R25 835.01) = R1 783.37
Therefore, Jabu's monthly increase is R1 746.25 (rounded to the nearest cent).

What is a probability?A subfield of statistics known as probability studies random events and their likelihood of happening.
1. There are 11 toppings and each topping can be either included or excluded from a pizza, there are 2 choices for each topping. Therefore, there are 2^11 = 2048 ways to make one pizza. For two pizzas, there are 2048*2048 = 4194304 ways to choose the two pizzas.
2. For one pizza with up to five toppings, we can use combinations to determine the number of ways to choose toppings. Since we have 11 toppings to choose from and can choose up to 5, the number of ways to choose is:
C(11, 1) + C(11, 2) + C(11, 3) + C(11, 4) + C(11, 5) = 11 + 55 + 165 + 330 + 462 = 1023
3. If the two pizzas are identical, there is only one way to build the two pizzas.
4. If the two pizzas are different, we need to choose 2 of the 1023 possibilities from problem 2. Since order doesn't matter, we use combinations, and the number of ways to choose is:
C(1023, 2) = 523,503
5. The total number of ways to make two pizzas with up to five toppings each is the sum of the answers from problems 3 and 4:

Assume that TDW Corporation (calendar year-end) has 2022 taxable income of $650,000 for purposes of computing the §179 expense. The company acquired the following assets during 2022: (Use MACRS Table 1, Table 2, Table 3, Table 4 and Table 5. ) Asset Placed in Service Basis Machinery September 12 $ 2,270,000 Computer equipment February 10 263,000 Furniture April 2 880,000 Total $ 3,413,000 a. What is the maximum amount of §179 expense TDW may deduct for 2022?
The maximum amount of §179 expense TDW may deduct for 2022 is $257,000.
To determine the maximum amount of §179 expense that TDW Corporation can deduct for 2022, we first Add up the cost of all the assets acquired in 2022:
$2,270,000 (machinery) + $263,000 (computer equipment) + $880,000 (furniture) = $3,413,000
Now we determine the amount of the §179 deduction limit for the tax year.
For tax year 2022, the §179 deduction limit is $1,050,000.
Check if the cost of the assets exceeds the §179 deduction limit.
Since the cost of the assets ($3,413,000) is greater than the §179 deduction limit ($1,050,000), we need to calculate the phase-out limit.
Now we determine the phase-out limit.
For tax year 2022, the phase-out limit is $2,620,000.
Calculate the §179 expense deduction.
Since the cost of the assets ($3,413,000) is greater than the phase-out limit ($2,620,000), we need to reduce the §179 deduction by the excess over the phase-out limit.
The excess over the phase-out limit is $793,000 ($3,413,000 - $2,620,000).
The §179 expense deduction is the lesser of the §179 deduction limit and the cost of the assets reduced by the excess over the phase-out limit.
The §179 expense deduction is $1,050,000 - $793,000 = $257,000.

Use the multiplication method to increase £88 by 14%
To increase £88 by 14%, we can use the multiplication method, which involves multiplying the original amount by the decimal equivalent of the percentage increase.
The multiplication method is a mathematical technique used to solve problems involving multiplication. It involves breaking down numbers into their constituent parts and then multiplying those parts together to arrive at the final answer.
To find the decimal equivalent of 14%, we divide the percentage by 100:
14% ÷ 100 = 0.14

for a ride, a taxi driver charges an initial fare of $3.00 plus $0.40 for each 1 5 of a mile driven. if the total charge for a ride is $27.00, what is the distance traveled, in miles?
The taxi driver charges an initial fare of $3.00 plus $0.40 for each 1/5 of a mile driven. If the total charge for a ride is $27.00, the distance traveled, in miles is 9.
The data given in the question is, The taxi driver charges an initial fare of $3.00 plus $0.40 for each 1/5 of a mile driven. The total charge for a ride is $27.00.
Let's calculate the distance traveled:
Let d be the distance traveled. The given data in the problem is in dollars and cents. Therefore, let's first change it to the same units (cents). We know that 1 dollar is equal to 100 cents. Thus $27.00 is equal to 27 * 100 cents.
Therefore, $27.00 is equal to 2700 cents.
Now, we know that the driver charges $3.00 as an initial fare.
So, he charged 300 cents. Therefore, the remaining amount of money he charged for the distance is (2700 - 300) cents.
Hence, he charged 2400 cents for the distance traveled. The driver charges $0.40 for each 1/5 of a mile. That is 40 cents for each 1.2 km.
Therefore, he charges 200 cents for each 1.2 km of distance traveled.
Hence, he charges (2400/200) * 1.2 km of distance traveled.
Therefore, the distance traveled is 14.4 km or 9 miles. Accordingly, the distance traveled, in miles, is 9.

what is circle ?A circle in geometry is a closed object made up of all points in a plane that are equally spaced out from a specific point known as the centre. The diameter of a circle is the distance through its centre; the radius is the distance from any point on the circle to that point. Any three locations that are located on a circle can be used to describe it, in addition to its centre point and radius. A circle's circumference, also known as its perimeter, can be calculated using the formula C = 2r, where r denotes the radius and is a mathematical constant roughly equivalent to 3.14. The equation A = r2 determines the area of a circle.
given
We must deduct the area of triangle OAB (the sector) from the area of trapezium ABCD in order to determine the area of the shaded zone formed by points ABDC inside circle sector OAB.
Finding the sector's area is the first step. The sector's central angle is 75 degrees, or (75/360) of the complete circle. Hence, this is the sector's geographic scope:
(75/360)r2, where r is the circle's radius.
Inputting r=4cm results in:
(75/360)π(4)² = (5/12)π cm²
The area of the trapezium must then be located. Finding the height of the trapezium, which is the separation between lines AB and CD, is necessary to do this.
Using the Pythagorean Theorem, the following can be discovered:
h² = (OA)² - (CA) (CA) ²
h² = 4² - 3²
h = √7 cm
The trapezoid's surface area is:
(1/2)(AB+CD)
h = (1/2)(6+4)
(√7) = 5√7 cm²
Lastly, we can calculate the area of the darkened area by deducting the sector's area from the trapezoid's area:
7.11 [tex]cm^{2}[/tex] is the area of the darkened area, or 57 - (5/12). (rounded to two decimal places) .

Mr. Salinger has 8 packs of seeds. The line plot shows the weight of each pack. Mr. Salinger wants to redistribute the seeds in such a way that each pack weighs the same. What will be the weight of each pack?
Each pack should weigh 11.5 oz when the seeds are redistributed equally.
Since Mr. Salinger wants to redistribute the seeds in such a way that each pack weighs the same, he needs to find the common weight of all the packs. To do this, he can find the total weight of all the packs and divide it by the number of packs.
Using the line plot, we can see that the weights of the 8 packs are:
12 oz
8 oz
10 oz
10 oz
12 oz
14 oz
10 oz
16 oz
To find the total weight of all the packs, we can add these weights together:
12 + 8 + 10 + 10 + 12 + 14 + 10 + 16 = 92 oz
So the total weight of all the packs is 92 oz.
To find the weight of each pack, we need to divide the total weight by the number of packs:
92 ÷ 8 = 11.5 oz

Frank organized a raffle. He sells 300 tickets for £5 each. The prizes cost £400. He gives 55% of the profit to Charity A and 45% of the profit to Charity B. Work out how much each charity receives.
Answer:
Step-by-step explanation:
The total revenue from selling 300 tickets for £5 each is:
300 x £5 = £1500
The profit will be the difference between the total revenue and the cost of prizes:
£1500 - £400 = £1100
The amount of profit that goes to Charity A is:
55% x £1100 = £605
The amount of profit that goes to Charity B is:
45% x £1100 = £495
Therefore, Charity A receives £605 and Charity B receives £495.

What is the exact value of side x in the Trina for below? 20in 30 degree and X?
According to the question, the exact value of side x in the Trina are 34.641016151377546in.
What is value?Value is an intangible concept that refers to the worth of something, whether it is tangible or intangible. It is based on the perceived benefits and costs associated with the thing in question. Value can be subjective, as different people may place different worth on the same item. Value can also be objective, as there may be a set market price for a certain item.
The exact value of side x in the triangle can be determined by using the law of sines. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is the same for all sides of a triangle.
Therefore, we can set up the following equation:
(20in/sin30°) = (x/sin60°)
Solving for x, we get:
x = 20in×(sin60°/sin30°)
x = 20in×(√(3)/1)
x = 20in×√(3)
x = 34.641016151377546in

The exact value of side x in the Trina, according to the question, is 34.641016151377546in.
What is Exact value?Where you cannot predict the value, you must be specific. An exact number is a value that can be determined with absolute precision. Counted quantities of objects or sure unit conversions are examples of exact numbers.
The term "approximate number" refers to a number that is close to the precise number, and there is always a difference among exact and approximate numbers. For instance, are exact integers because no approximation is required.
As a result, we can construct the following equation:
(20in/sin30°) = (x/sin60°)
Solving for x, we get:
x = 20in×(sin60°/sin30°)
Simplify the above equation,
x = 20in×(√(3)/1)
x = 20in×√(3)
The value of x is,
x = 34.641016151377546in

a run test is conducted for a process. the z-test value is calculated to be -1.5. if the run test acceptable limits are /- 2sigma you would conclude?
The conclusion of the test is the calculated z-test value of -1.5 falls within the acceptable limits of +/- 2 sigma.
To interpret the results of the run test, we need to compare the calculated z-test value with the acceptable limits for the test. The acceptable limits for the run test are +/- 2 sigma, which means that the process is considered acceptable if the z-test value falls within this range.
Since the z-value of -1.5 falls within the acceptable limits of +/- 2 sigma, we can conclude that the process is acceptable according to the run test. This means that there is no evidence of non-randomness or nonconformity in the process, and the process is functioning as expected.

How many people were in the group that popped 10 balloons?
We can see that this corresponds to the point (4, 10). Therefore, there were 4 people in the group that popped 10 balloons.
Describe Correlation?Correlation refers to the relationship between two variables in a dataset. It is a statistical measure that quantifies the degree to which two variables are related to each other.
There are two types of correlation: positive and negative. Positive correlation exists when the two variables move in the same direction, meaning that as one variable increases, the other variable also increases. Negative correlation exists when the two variables move in opposite directions, meaning that as one variable increases, the other variable decreases.
The strength of the correlation can be measured using a correlation coefficient, which ranges from -1 to +1. A correlation coefficient of +1 indicates a perfect positive correlation, while a correlation coefficient of -1 indicates a perfect negative correlation. A correlation coefficient of 0 indicates no correlation between the two variables.
From the given graph, we can see that there is a positive correlation between the number of people in a group and the total number of balloons they pop. As the number of people in the group increases, the total number of balloons they pop also tends to increase.
We are asked to find the number of people in the group that popped 10 balloons. From the graph, we can see that this corresponds to the point (4, 10). Therefore, there were 4 people in the group that popped 10 balloons.

(3, 3)
Point A is three units left and three units up from the origin, so its coordinates are (-3, 3). Therefore, the correct answer is option 2) (-3, 3).
The topic of coordinate geometry involves the use of the Cartesian plane, also known as the coordinate plane or xy-plane, to graph and analyze relationships between points, lines, and shapes. The plane consists of two perpendicular number lines called the x-axis and the y-axis.
The origin, denoted by the point (0, 0), is the point where the two axes intersect. Points on the plane are represented by ordered pairs of numbers (x, y), where x is the distance from the y-axis and y is the distance from the x-axis. Lines on the plane can be represented by their slope and y-intercept, while shapes like circles, rectangles, and triangles can be graphed and analyzed using their respective formulas.
