John runs a computer software store. Yesterday he counted 121 people who walked by the store, 66 of whom came into the store. Of
Dominik [7]

Answer:

a) There is a 55% probability that a person who walks by the store will enter the store.

b) There is a 38% probability that a person who walks into the store will buy something.

c) There is a 21% probability that a person who walks by the store will come in and buy something.

d) There is a 62% probability that a person who comes into the store will buy nothing.

Step-by-step explanation:

This a probability problem.

The probability formula is given by:

P = \frac{D}{T}

In which P is the probability, D is the number of desired outcomes and T is the number of total outcomes.

The problem states that:

121 people walked by the store.

66 people came into the store.

25 bought something in the store.

(a) Estimate the probability that a person who walks by the store will enter the store.

121 people walked by the store, 66 of whom entered the store. So:

D = 66, T = 121

P = \frac{D}{T} = \frac{66}{121} = 0.55

There is a 55% 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.

66 people walked into the store, 25 of whom bought something. So:

D = 25, T = 66

P = \frac{D}{T} = \frac{25}{66} = 0.38

There is a 38% 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.

121 people walked by the store, 25 of whom entered the store. So:

D = 25, T = 121

P = \frac{D}{T} = \frac{25}{121} = 0.21

There is a 21% 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.

Of the 66 people whom came into the store, 25 bought something. This means that 66-25 = 41 of them did not buy anything. So:

D = 41, T = 66

P = \frac{D}{T} = \frac{41}{66} = 0.62

There is a 62% probability that a person who comes into the store will buy nothing.

Calvin has $360 less in his savings account than he had 8 weeks ago. Each
maksim [4K]

Answer:

<u>Calvin withdraws $ 60 each week</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Calvin's account balance difference than 8 weeks ago = - $ 360

Weekly amount Calvin deposits = $ 15

Number of weeks to compare = 8

2. What was his average withdrawal  each week?

Let's calculate the weekly average withdrawal this way:

Weekly average withdrawal = [Calvin's account balance difference than 8 weeks ago - (Weekly amount Calvin deposits * Number of weeks to compare)]/Number of weeks to compare

Replacing with the values given:

Weekly average withdrawal = [-360 - (15 * 8)]/8

Weekly average withdrawal = -360 - 120 / 8

Weekly average withdrawal = -480 / 8

<u>Weekly average withdrawal = -60</u>

<u>Calvin withdraws $ 60 each week</u>

7(x+3)=-2(x-5) <br> Help pls?
olganol [36]

Answer:

x = -11/9

Step-by-step explanation:

7(x+3)=-2(x-5)

Distribute

7x+21 = -2x+10

Add 2x to each side

7x+21 +2x = -2x+10+2x

9x +21 = 10

Subtract 21 from each side

9x +21-21 = 10-21

9x = -11

Divide each side by 9

9x/9 = -11/9

x = -11/9
