F(x) = 2x – 1 What is f(13)?

Mathematics

Leto [7]3 years ago

Answer:

<h2>f(13) = 25</h2>

Step-by-step explanation:

f(x) = 2x – 1

To find f(13) substitute the value of x that's 13 into f(x). That is for every x in f (x) replace it with 13

We have

f(13) = 2(13) - 1

= 26 - 1

We have the final answer as

<h3>f(13) = 25</h3>

Hope this helps you

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

Therefore, the mean number of rockets hits in the region is 533.
