Step-by-step explanation:

given,

10% A grades 80% B grades 10% C grades

This year, managers with scores less than 35 received C's and those with scores above 425 received A's.

The mean has to be middle of two corresponding cutoff value

$\mu = \dfrac{35+425}{2}$

μ = 230

Cutoff Off C grade corresponds with the area of 0.10 is table A.

corresponding z- score according to Table A

Z = -1.28

now, standard deviation

$z = \dfrac{x-\mu}{\sigma}$

$\sigma= \dfrac{x-\mu}{z}$

$\sigma= \dfrac{35-230}{-1.28}$

σ = 152.3

Correct answer is option A

In the given diagram, find the values of x, y, and z.

anyanavicka [17]

Answer:

B) x=64, y=21, z=64

Step-by-step explanation:

X=180-116=64

Y cannot equal 115, and one angle is already 95, and that would put it over 180. The only remaining choice for y=21

z=180-95-21=64

3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6
