Step-by-step explanation:

Calculate the the total number of the boxes. We can calculate it by counting number of the rows and the number of the columns and then multiplying it.

Total number of rows = 10

Total number of columns = 10

Total boxes = 100

Shaded boxes = 72

We calculate %age by,

=> Selected boxes/Total boxes x 100

=> 72/100 x 100

=> 72%

Hope it helps :)

Of all the visitors to a museum on Saturday, 18% were kids younger than 11 years old. In lowest terms, write the fraction of vis

Aleksandr-060686 [28]

<h3>Answer: 9/50</h3>

Explanation:

Any percentage converts to that number over 100.

So 18% would convert to 18/100

We then reduce the fraction by dividing each part by the GCF 2

18/2 = 9

100/2 = 50

The fraction 18/100 fully reduces to 9/50

dem82 [27]

Answer: 3 pounds

Step-by-step explanation:

The equation can be set up according to slope form: y=mx+b where x represents cost per round.

$70 = $7.51x + $47.47

Subtract 47.47 to both sides: $22.53 = $7.51x

Divide both sides by 7.51: 3 = x

Answer:

0.55% probability that exactly 5 out of the first 13 customers buy a magazine

Step-by-step explanation:

For each customer, there are only two possible outcomes. Either they buy a magazine, or they do not. The probability of a customer buying a magazine is independent of other customers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

10% of his customers buy a magazine

This means that $P = 0.1$

What is the probability that exactly 5 out of the first 13 customers buy a magazine?

This is P(X = 5) when n = 13. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{13,5}.(0.1)^{5}.(0.9)^{8} = 0.0055$

0.55% probability that exactly 5 out of the first 13 customers buy a magazine
