Answer:
0.0066
Step-by-step explanation:
Given that:
Mean
= 75
Variance 
The standard deviation 
The sample size n = 100









Using the Z table;
P(x > 83.7) = 1 - 0.9934
P(x > 83.7) = 0.0066
Thus, probability = 0.0066
Hello!
The angle is a right angle, which measures 90°.
3x + x = 4x
Angle = 4x + 10 = 90
Switch that around
90 - 10 = 4x
90 - 10 = 80
80 = 4x
Divide by 4

Answer:
D
Step-by-step explanation:
x³ = 64/27
Take the cube root of both sides.
x = ∛(64/27)
Distribute the cube root to the numerator and denominator.
x = (∛64)/(∛27)
Take the cube root of the terms.
x = 4/3
