11 9/10 and 3 2/5

\left \{ {{ 11\frac{9}{10}+3\frac{2}{5}=15\frac{3}{10}} \atop { 11\frac{9}{10}-3\frac{2}{5}=8\frac{5}{10}}} \right.

To solve for this, you can create a series of two equations
\left \{ {{y+x=15 \frac{3}{10} } \atop {y-x= 8\frac{5}{10} }} \right.

After that, you solve one of the equations for x and plug it into the other equation.
\left \{ {{x=15 \frac{3}{10}-y } \atop {y-x= 8\frac{5}{10} }} \right.

{2y-15 \frac{3}{10}= 8\frac{5}{10}

Then, solve for variable y
{2y=23 \frac{8}{10}
{y=11\frac{9}{10}

Then, you plug in this value for y into one of the original equations

11\frac{9}{10}+x=15 \frac{3}{10}

x=15 \frac{3}{10} -11\frac{9}{10}

x=3 \frac{2}{5}

If you factor the denominator of the left multiplicand...

[(a-4)(a+3)]/[a(a-4)]  you can see that the (a-4)s cancel out leaving:

(a+3)/a

now you have

(a+3)/a * 2a^3/((a+3)(a-1))  so the (a+3)s cancel out leaving:

1/a * 2a^3/(a-1)  which is:

2a^3/(a(a-1))  so now a^1 cancel leaving

2a^2/(a-1)

An automobile manufacturer claims that its jeep has a 53.9 miles/gallon (MPG) rating. An independent testing firm has been contr
Advocard [28]

Answer:

Value of the test statistic, z_{test}  = - 1.17

Step-by-step explanation:

Null hypothesis, H_{0}: \mu = 53.9

Alternative hypothesis, H_{a} : \mu \neq 53.9

Sample mean, \bar{X} = 53.7

Sample size, n = 110

Standard deviation, \sigma = 1.8

Significance level, \alpha = 0.02

The value of the test statistics is given by the formula:

z_{test}  = \frac{\bar{X} - \mu}{\frac{\sigma}{\sqrt{n} } } \\z_{test}  = \frac{53.7 - 53.9}{\frac{1.8}{\sqrt{110} } } \\z_{test}  = - 1.17
