Answer:

<h2>The speed is 2808 ft/s</h2>

Step-by-step explanation:

step one:

In this problem we are expected to substitute the value of d in the expression for velocity given as

$s=24d$

step two:

Given that

d= 117 ft

Substituting the value for d in the given equation we have

$s= 24*117\\\\s=2808 ft/s$

<em>The problem basically tests our ability to perform basic substitution operation which we have performed, should you have any question or doubt, kindly respond to this question</em>

Answer:

The estimated mean number of rockets hits in the region is 533.

Step-by-step explanation:

We are given the following information,

Number of rocket hits | Observed number of regions

0 | 228

1 | 214

2 | 94

3 | 32

4 | 7

5 | 0

6 | 0

7 | 1

We are asked to estimate the mean number of rocket hits in the region.

The mean or expected value is given by

$\mu = \sum (x \cdot P(x)) \\\\\mu = (0 \cdot 228) + (1 \cdot 214) + (2 \cdot 94) + (3 \cdot 32) + (4 \cdot 7) + (5 \cdot 0) + (6 \cdot 0) + (7 \cdot 1) \\\\\mu = 0 + 214 +188+ 96 +28 +0+ 0 + 7 \\\\\mu = 533$
