Answer:

1/3

Step-by-step explanation:

$\left[\begin{array}{cccc}Bought\ Lunch&Boys&Girls&Total\\0\ up\ to\ 10&10&5&15\\10\ up\ to\ 20&20&25&45\\Total&30&30&60\end{array}\right]$

The number of boys who bought 10 to 20 lunches is 20.

The total number of students is 60.

So the probability is 20/60 = 1/3.

A rock is dropped from the top of a 2000-foot building. After 1 second, the rock is traveling 32 feet per second. After 2 second

alexandr402 [8]

Using the pairs (1,32) and (2,64) the rate of speed is (64-32 / 2-1 = 32 feet per second.

To find the rate of decent you would multiply the rate by time:

The equation is y = 32x

B. Replace x with 15 and solve for y:

Y = 32(15)

Y = 480

The rate of speed is 480 feet per second.
