Answer:
87.9
Step-by-step explanation:
Use a calculator or table to find the z-score that corresponds to 25%.
P(Z < z) = 0.25
z = -0.675
Now find the value that corresponds to that z score.
z = (x − μ) / σ
-0.675 = (x − 101.3) / 19.9
x = 87.9

Answer:
m < 4 = 44 degrees
Step-by-step explanation:
Here, we want to find the value of the given angle.
Mathematically, when two angles are complement of each other, they add up
to be 90 degrees. These angles are termed complementary angles.
Thus, by mathematical convention is this present case;
m <3 + m< 4 = 90
46 + m<4 = 90
m<4 = 90-46
m< 4 = 44 degrees
The answer would be £480 because 20% of 600 is 120 and 600 take away 120 is 480
