Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 13², so

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = $\sqrt{25}$ = 5

1. The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75

Diano4ka-milaya [45]

We will use the amount Jermaine used to determine the admission price, since that is not given to us. The total amount he paid is equal to the sum of the price of the tickets and the amdission price, a. We get the equation 43.75 = 1.25 * 25 + a a = $12.5 Now, if a person comes to the fair and pays for only the rides and admission, we can form an equation in x, the number of ride tickets, and y, the total cost incurred by that person. y = 1.25x + 12.5 Here, y is the total cost, 1.25 is the price per ticket, x is the number of tickets and 12.5 is the admission cost.

Hope this help.

Answer: P(A or B) = 22/26 or 11/13

Step-by-step explanation:All in all there are 26 pieces of clothing available. The probability of randomly selecting a blue piece is equal to 18/26. Also, the probability of picking up a pants is 14/26. There are 10 blue pants and the probability of picking up one of those is 10/26. The answer can be computed as follows:

P(A or B) = (18/26) + (14/26) - (10/26) = 22/26

P(A or B) = 22/26 or 11/13

Answer:

The probability that none of the three shoppers purchased electronics is 0.528

Step-by-step explanation:

Completing missing parts of the question

Electronics - 18

Pet supplies - 25

Toys - 40

Office supplies - 12

Total = 95

The probability that none of the three shoppers purchased electronics is calculated as follows.

Electronics Shoppers = 18

Non electronic shoppers = 95 - 18 = 77

Probability without replacement;

Probability that the first shopper didn't buy electronics = 77/95

Probability that the second shopper didn't buy electronics = 76/94

Probability that the third shopper didn't buy electronics = 75/93

Multiplying these values gives us our result.

Probability = 77/95 * 76/94 * 75/93

Probability = 0.528483184625943

Probability = 0.528 --- approximated

Hence, the probability that none of the three shoppers purchased electronics is 0.528
