(b) 2.32
(c) -2
(d) 0.9867
(e) 2.9867
Step-by-step explanation:
The <em>z</em>-score of a raw score <em>X</em> is a standardized score that follows a normal distribution with mean 0 and standard deviation 1.
The formula to compute the <em>z</em>-score is:
<u>Given</u>:
Mean (<em>μ</em>) = $775
Standard deviation (<em>σ</em>) = $75
(a)
For <em>X</em> = $699 the <em>z</em>-score is:
(b)
For <em>X</em> = $949 the <em>z</em>-score is:
(c)
For <em>X</em> = $625 the <em>z</em>-score is:
(d)
For <em>X</em> = $849 the <em>z</em>-score is:
(e)
For <em>X</em> = $999 the <em>z</em>-score is:
Answer:
x=8
Step-by-step explanation:
this is an equilateral triangle, which means all sides are equal
if all the sides are equal, all the angles are equal
the three angles are all equal to 60 degrees (180/3 = 60)
7x+4 = 60
subtract 4 from each side
7x = 56
divide by 7 on each side
x = 8
