The measure of length SV is 60 units
<h3>Isosceles Right Triangle</h3>An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.
The above means that:
Substitute values for SV and ST
Subtract z from both sides
From the figure, we have:
Substitute 30 for z
Hence, the measure of length SV is 60 units

Answer: The sample mean salary of our sampled business majors= 60k .
Step-by-step explanation:
We know that a confidence interval is give by :_
(i)
, where = Sample mean
E = margin of error
Given : A 95% confidence interval for the true mean salary of graduating business majors: (50k, 70k).
As compared to (1) , we have
Add (1) and (2) , we get
∴ The sample mean salary of our sampled business majors= 60k .
