oee [108]2 years ago

5 0

Answer:

h = 38

Step-by-step explanation:

$\frac{h + 52}{70} = \frac{9}{7}$

$h + 52 = \frac{9}{7} \times 70$

$h + 52 = \frac{9 \times 70}{7}$

$h + 52 = \frac{630}{7}$

$h + 52 = 90$

$h = 90 - 52$

$h = 38$

the answer is 38.

In order to estimate the difference between the average hourly wages of employees of two branches of a department store, the fol

Julli [10]

Answer:

$0.071,1.928$

Step-by-step explanation:

Downtown Store North Mall Store

Sample size n 25 20

Sample mean $\bar{x}$ $9 $8

Sample standard deviation s $2 $1

$n_1=25\\n_2=20$

$\bar{x_1}=9\\ \bar{x_2}=8$

$s_1=2\\s_2=1$

$x_1-x_2=9-8=1$

Standard error of difference of means = $\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

Standard error of difference of means = $\sqrt{\frac{2^2}{25}+\frac{1^2}{20}}$

Standard error of difference of means = $0.458$

Degree of freedom = $\frac{\sqrt{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}})^2}{\frac{(\frac{s_1^2}{n_1})^2}{n_1-1}+\frac{(\frac{s_2^2}{n_2})^2}{n_2-1}}$

Degree of freedom = $\frac{\sqrt{(\frac{2^2}{25}+\frac{1^2}{20}})^2}{\frac{(\frac{2^2}{25})^2}{25-1}+\frac{(\frac{1^2}{20})^2}{20-1}}$

Degree of freedom =36

So, z value at 95% confidence interval and 36 degree of freedom = 2.0280

Confidence interval = $(x_1-x_2)-z \times SE(x_1-x_2),(x_1-x_2)+z \times SE(x_1-x_2)$

Confidence interval = $1-(2.0280)\times 0.458,1+(2.0280)\times 0.458$

Confidence interval = $0.071,1.928$

Hence Option A is true

Confidence interval is $0.071,1.928$

Find the area and perimeter of that triangle

aleksandrvk [35]

Step-by-step explanation:

$A = \frac{1}{2}(b*h)$

$A=\frac{1}{2} (14*5)$

$A=\frac{1}{2} (70)$

<em>A = 35</em>

<em></em> $P = s+s+s$ <em></em>

<em></em> $P=12+14+6$ <em></em>

<em>P = 32</em>
