Answers

Answer:

The diagram is attached below which shows the location of the point (-5, -9)

Step-by-step explanation:

Given the point

(-5, -9)

The location of the point (-5, -9) can be determined by locating the point at x=-5 and y = -9.

Please check the attached diagram where I located the point (-5, -9).

From the attached diagram, it is clear that:

Moving 5 units to the left from the origin (0, 0) and then moving 9 units down would get us to the location x = -5 and y = -9.

The diagram is attached below which shows the location of the point (-5, -9)

John runs a computer software store. Yesterday he counted 137 people who walked by the store, 56 of whom came into the store. Of the 56, only 25 bought something in the store.
A) Estimate the probability that a person who walks by the store will enter the store.B) Estimate the probability that a person who walks into the store will buy something.C) Estimate the probability that a person who walks by the store will come in and buy something.D) Estimate the probability that a person who comes into the store will buy nothing.

Answers

Answer:

John's Computer Software Store

A) Probability that a person who walks by the store will enter the store:

= 41%

B) The probability that a person who walks into the store will buy something:

= 45%

C) The probability that a person who walks by the store will come in and buy something:

= 18%

D) The probability that a person who comes into the store will buy nothing:

= 55%

Step-by-step explanation:

a) Data and Calculations:

Number of people who walked by the store yesterday = 137

Number of those who came into the store = 56

Number of people who came into the store and bought something = 25

Number of people who came into the store and bought nothing = 31 (56 - 25)

A) Probability that a person who walks by the store will enter the store:

= 56/137

= 0.4087

= 0.41

= 41%

B) The probability that a person who walks into the store will buy something:

= 25/56

= 0.4464

= 0.45

= 45%

C) The probability that a person who walks by the store will come in and buy something:

= 56/137 * 25/56

= 0.41 * 0.45

= 0.1845

= 0.18

= 18%

D) The probability that a person who comes into the store will buy nothing:

= 31/56

= 0.5536

= 0.55

= 55%

Fran used a graphics program to reduce a
digital image. The original dimensions of the
image were 20 cm wide by 12 cm long. She
used a scale factor of 0.6. What are the
dimensions of the reduction?

Answers

Answer:

The reduced dimensions are:

Width = 12 cm

Length = 7.2 cm

Step-by-step explanation:

Original dimensions of Image:

Width = 20 cm

Length = 12 cm

Fran reduced the dimensions using a scale factor of 0.6

We need yo find dimensions of reduction.

We would multiply the original dimensions by 0.6 to find the new dimensions.

So, Width = 20 * 0.6 = 12

length = 12 * 0.6 = 7.2

So, the reduced dimensions are:

Width = 12 cm

Length = 7.2 cm

Two cars start from the same point and move in a straight line, one east at a speed of 60 km per hour and the other west at a speed of 80 km per hour. After what time will they live at a distance of 770 km?

Answers

Answer:

5.5 hours

Step-by-step explanation:

Given that :

Speed of A = 60 kmphr

Speed of B = 80 kmphr

After what time will distance = 770 km

Speed * Time = Distance

Let time = x

Distance A + Distance B = 770

(60 * x) + (80 * x) = 770

60x + 80x = 770

140x = 770

x = 770 / 140

x = 5.5 hours

Answers

Answer:

[tex]600\ rupees[/tex]

Step-by-step explanation:

[tex]We\ are\ given:\\Dimensions\ of\ the\ door=2m *1m\\Dimensions\ of\ the\ wall=8.5m*2m\\Cost\ of\ whitewashing\ of\ 1m^2=40\ rupees\\Hence,\\First\ lets\ consider\ the\ wall:\\Area\ of\ a\ rectangle= Length*Width\\Here,\\Length\ of\ the\ wall=8.5\ m\\Width\ of\ the\ wall=2\ m[As\ here\ width\ and\ height\ are\ the\ same\ thing]\\Hence,\\Area\ of\ the\ wall=8.5*2=17\ m^2[/tex]

[tex]Now,\\Lets\ consider\ the\ door:\\As\ we\ know\ that,\\Area\ of\ a\ rectangle=Length*Width\\Here,\\Length\ of\ the\ door=2m\\Width\ of\ the\ door=1\ m\\Hence,\\Area\ of\ the\ door=2*1=2m^2\\\\Now,\\The\ area\ to\ be\ whitewashed=Area\ of\ the\ wall-Area\of\ the\ door\\Hence,\\The\ area\ to\ be\ whitewashed=17-2=15\ m^2\\\\As\ we\ know\ that,\\Cost\ of\ whitewashing\ 1\ m^2\ of\ the\ wall= 40\ rupees\\Hence,\\[/tex]

[tex]Cost\ of\ whitewashing\ the\ whole\ wall=Area\ of\ the\ wall\ to\ be\\ whitewashed*Rate\ of\ whitewashing\ per\ m^2\\Hence,\\Cost\ of\ whitewashing\ the\ whole\ wall=15*40=600\ rupees[/tex]

The probability of selecting 3 female employees and 7 male employees to win a promotional trip a company with 10 female and 50 male employees would best be modeled with the _______.

Answers

Answer:

The best model is hypergeometric distribution.

Step-by-step explanation:

The probability would be best modeled with hypergeometric distribution.

Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.

The hypergeometric distribution differs from the binomial distribution in the lack of replacements.

Thus, the best model is hypergeometric distribution.

Which graph shows the solution to the inequality -3x-720?

Answers

Answer:

x>-9

Step-by-step explanation:

The given inequality is :

-3x - 7 < 20

We need to find the solution of the inequality using graph.

-3x - 7 < 20

Add 7 to both sides

-3x-7+7 < 20+7

-3x <27

x>-9

Hence, the attatched graph shows the solution of the given inequality.

Your boss sends you an email and explains that your fourth location is to Ellis Island to visit the Statue of Liberty. She emails you a scale drawing that one of the architectures in Spain created.

(Please explain thoroughly step by step on how you solved the problem.If you can,please provide an image on how you solved the problem.)

Answers

Step-by-step explanation:

3/6 - 2/5 = 0.1

4/7 - 3/6 = 0.071

5/8 - 4/7 = 0.053

Since there is no common difference d, the sequence is not arithmetic.

(3/6) / (2/5) = 1.25

(4/7) / (3/6) = 1.14

(5/8) / (4/7) = 1.09

Since there is no common ratio, the sequence is not geometric.

Hence the sequence is neither an AP or GP.

Step-by-step explanation:

[tex]m_{KL}[/tex] = [tex]\frac{-3-1}{3-2}[/tex] = - 4

Slope of perpendicular line is [tex]\frac{1}{4}[/tex]

y - 1 = - 4(x - 2) ⇔ y = - 4x + 9

Equation of the perpendicular to KL from point M(4, - 3) is

L(2, 1)

[tex]m_{LM}[/tex] = [tex]\frac{-3-1}{4-2}[/tex] = - 2

Slope of perpendicular line is [tex]\frac{1}{2}[/tex]  

y - 1 = - 2(x - 2) ⇔ y = - 2x + 5

Equation of the perpendicular to LM from point K(3, - 3) is

y + 3 = [tex]\frac{1}{2}[/tex] (x - 3) ⇔ y = [tex]\frac{1}{2}[/tex] x - 4.5 ....... (2)
