B(2b-4)
b=5

The way to solve a simultaneous equation is to substitute the number value of the given letter into the expression. It then becomes 5(2(5)-4).
you can put this into your calculator or just work it out by hand.
5(2(5)-4)= 30

5x(2x(5)-4)
5x(10-4)
5x(6)
=30

____ [38]

Answer:

See below for answers and explanations

Step-by-step explanation:

<u>Part A</u>

Assuming that conditions have been met for the interval, we use the formula $\displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}}$ where $\bar{x}$ represents the sample mean, $t$ represents the critical value, $s$ represents the sample standard deviation, and $n$ is the sample size.

The critical value of $t$ for an 80% confidence level with degrees of freedom $df=n-1=25-1=24$ is equivalent to $t=1.317836$

Thus, we can compute the confidence interval:

$\displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}}\\\\CI=32.64\pm1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\\\\CI\approx\{30.17,35.11\}$

Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.

<u>Part B</u>

The margin of error is $\displaystyle t\frac{s}{\sqrt{n}}=1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\approx2.47$

Answer:

6 4/7

Step-by-step explanation:

Convert any whole numbers to mixed numbers

$\frac{12}{1} \times \frac{23}{42}$

Use fractions formula

$\frac{a \times b}{c \times d} = \frac{e}{f}$

$\frac{12 \times 23}{1 \times 42} = \frac{276}{42}$

Count how many times 276 goes into 42 <em>evenly</em>

<em></em> $= 6\frac{4}{7}$
