777dan777 [17]

Answer:

20% probability that the next customer will pay with cash

Step-by-step explanation:

A probability, as a decimal, is the number of desired outcomes divided by the number of total outcomes.

To find as percent, we multiply by 100.

In this question:

Total of 54+63+153 = 270 customers.

Of those, 54 paid with cash.

Based on the number of customers from last week, what is the probability as a percent that the next customer will pay with cash?

54/270 = 0.2

0.2*100 = 20%

20% probability that the next customer will pay with cash

What is the working out for 5x+3=2x+15

Nataliya [291]

The solution is x = 4

Step-by-step explanation:

The given equation is a linear equation so it will have only one equation

Given equation is:

$5x+3=2x+15$

Subtraction property of equality:

$5x+3-3 = 2x+15-3\\5x = 2x+12$

Subtraction property of equality:

$5x-2x = 2x-2x+12\\3x = 12$

Division Property of Equality:

$\frac{3x}{3} = \frac{12}{3}\\x = 4$

Hence,

The solution is x = 4

Demi’s last 5 bowling scores were 68, 75, 90, 80. What was Femi’s mean score? A.72 B.75 C.77 D.79 D.

-Dominant- [34]

Complete Question:

Femi's last 5 bowling scores were 68, 75, 72, 90, and 80. What was Femi's mean score?

Answer:

Step-by-step explanation:

Given

Scores: 68, 75, 72, 90, and 80

Required

Determine the mean

The mean (M) of a data is calculated as thus:

$M = \frac{\sum x}{n}$

Where

n = number of data.

In this case,

n = 5

and

$\sum x$ = sum of data

So, the formula becomes

$M = \frac{68 + 75 + 72 + 90 + 80}{5}$

$M = \frac{385}{5}$

$M = 77$

Hence, the mean is 77
