A researcher was interested in comparing the salaries of female and male employees of a particular company. independent random s

amples of female employees (sample 1) and male employees (sample 2) were taken to calculate the mean salary, in dollars per week, for each group. A 95% confidence interval for the difference, µ1- µ2, between the mean weekly salary of all female employees and the mean weekly salary of all male employees was determined to be (-$110,-$10). Interpret the results.

Answer:

Based on  given data, we can say with 95% confidence that the female employees at this company average between $110 less and $10 less per week than the male employees.

Step-by-step explanation:

Sample 1 for female

Sample 2 for male

Confidence = 90%

Difference in mean weekly salary of all female employees and the mean weekly salary of all male employees  = µ₁- µ₂

So based on above given data, we can say with 95% confidence that the female employees at this company average between $110 less and $10 less per week than the male employees.

Solve the inequality x + 2 1/2 > -1/2. Graph the solution set on a number line.show your work.
antiseptic1488 [7]

Answer:

x > - 3

Step-by-step explanation:

x + 2\frac{1}{2} > - \frac{1}{2}      First turn 2\frac{1}{2} into an fraction since its easier. So it becomes \frac{5}{2}

x + \frac{5}{2} > - \frac{1}{2}

<u>   - </u>\frac{5}{2}<u>     - </u>\frac{5}{2}<u>  </u>       Do inverse operations, so subtract \frac{5}{2} from both sides.

    x > - \frac{6}{2}          Combine  - \frac{5}{2} with - \frac{1}{2}, which gives us - \frac{6}{2}

    x > - 3          Since we know that 6 divided by 2 is 3.

This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)

<-------------O--------------------------------------------------->

-5    -4     -3      -2       -1     0     1     2    3    4     5

So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.

padilas [110]

Answer: The value of x is 63

Step-by-step explanation:

Figure show two quadrilateral,

It is given that two quadrilateral are similar quadrilateral.

We know that

The respective sides of similar quadrilateral ( Like similar triangle) are in the ratio

We can write,

\frac{90}{10} =\frac{x}{7}

9=\frac{x}{7}[/tex]

x=63

Therefore, The value of x is 63
