Answer:

$MOE=\pm \ 1.41$

Step-by-step explanation:

-Given that $\sigma=1.91, n=7$

-We determine the z-value corresponding to the 95% confidence level:

$z_{\alpha/2}=z_{0.025}=1.96$

-The margin of error is the degree of error from the real value and is calculated as follows:

$MOE=\pm z_{\alpha/2} (\frac{\sigma}{\sqrt{n}})\\\\=\pm z_{0.025}\times\frac{\sigma}{\sqrt{n}}\\\\=\pm 1.96\times \frac{1.91}{\sqrt{7}}\\\\=\pm 1.41$

Hence, the margin of error is $\pm 1.41$

Answer:

Below.

Step-by-step explanation:

The equation and table shows were two boys pay for gym fees compare the rate of change and initial value for each function

Olegator [25]

The equation is an illustration of a linear function

The rate of change is 10 and the initial value is 25

<h3>How to determine the rate of change and the initial value</h3>

The equation is given as:

$C = 25 + 10m$

A linear equation is represented as:

$y = b + mx$

Where:

b represents the initial value
m represents the rate

By comparison:

b = 25

m = 10

Hence, the rate of change is 10 and the initial value is 25
