Answer:
422.4
Step-by-step explanation:
MP=480
Discount%=12%
SP=?
We know that,
SP=MP-Discount%of MP
=480-12%×480
=480-57.6
=422.4
In the diagram, mZXYZ = 115° and mZWXY = 45°.
Step-by-step explanation:
mXYZ+mXYW=180°(being straight angle)
mXYW =180-115
mXYW=65
now,
mXWY+mWXY+mXYW=180°(sum of angle of triangle)
mXWY=180-110
mXWY=70°
hope it helps.
The measure of the angle ∠XWY of the triangle is ∠XWY = 70°
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔXYZ
And , the measure of ∠XYZ = 115°
Now , the measure of ∠WXY = 45°
So , the measure of ∠XYW = 180° - 115° ( angles on a straight line = 180° )
And , the measure of ∠XYW = 65°
Now , the measure of ∠XWY = 180° - ( 45° + 65° ) ( angles in a triangle = 180° )
On simplifying , we get
The measure of angle ∠XWY = 70°
Hence , the angles of the triangle is solved

A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in. Find the length of a side.
The length of a side of the table is
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.
If there are 19 questions and each question has 4 answers, what is the probability she will answer at least one question correctly?
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958

Leslie has a watering can that holds 1 liter of water. She uses 250 milliliters of water on each of her plants. How many plants can she water? *remember 1L = 1000 milliliters of water
Answer:
4 plants
Step-by-step explanation:
convert the capacity of the watering can to millimeters
1L = 1000 milliliters
1 x 1000 = 1000 millimeters
Plants that can be watered = capacity of the watering can / amount of water a plant needs
1000 / 250 = 4 plants

a+b=8
3a - 45=3
And is it good for the elimination method
Answer: a is 16, b is -8
Step-by-step explanation:
3a-45=3
add 45 to both sides to get rid of -45
3a=48
divide both sides by 3
a = 16
plug 16 into the first equation
16 + b = 8
subtract 16 from both sides
b = -8
is it good for the elimination method? hmm i probably wouldn't use it in this case since there aren't any variables to cancel out.

A (skewed to the left)
Step-by-step explanation:
28 is a much smaller number (age) than the rest of the data, so it will be a negatively skewed distributio, aka, skewed to the left.
“A left skewed distribution is sometimes called a negatively skewed distribution because it's long tail is on the negative direction on a number line.”
“A distribution skewed to the left is said to be negatively skewed. This kind of distribution has a large number of occurrences in the upper value cells (right side) and few in the lower value cells (left side).”
