Answer:

0.14

Step-by-step explanation:

P(A|B) asks for the probability of A, given that B has happened. This is equal to the probability of A and B over the probability of B (see picture)

Here, the question is asking if someone is taking the bus given that they are a senior.

The probability of someone being a senior and taking the bus is 5/100, or 0.05 . The probability of someone being a senior is 35/100, or 0.35

Our answer is then 0.05/0.35 = 1/7 = 0.14

The circumference of a circle - $C=2 \pi r$

$C=62.8 \\ \\
62.8=2 \times 3.14 \times r \\
62.8=6.28r \\ \frac{62.8}{6.28}=r \\ r=10$

the number of a certain company’s video stores can be approximated by the linear equation y=-264x+4682, where x is the number of

kogti [31]

This problem is incomplete, but I think I know the probable question. Normally, you should have been given the target number of the company's video stores, so that you can replace the value of y and solve for x. Once you solve for x, you add this to year 1990 then you can solve for the year at which you can reach your target value. Suppose y = 3500 stores.

3500 = -264x + 4682
3500 - 4682 = -264x
-1182 = -264x
x = 4.48 years

Technically, that is equal to 4 years. Hence, the year would be 1990+4 = 1994.

Step-by-step explanation:

To find the mean, you need to add up all of the numbers and then divide by the amount of numbers.

4 + 5 + 8 + 12 + 12 + 13 + 14 + 15 = 83

83 ÷ 8 = 10.375
