The random variable X is normally distributed with mean μ=30 and standard deviation σ =10.
Use the transformation 
for calculating the probability. This value is called Z-score.
The Z score is 
.
Refer to the standard normal distribution table.
The probability
Answer:
hello :
x- intercepts when x = 0 : -4y = -20 so : y = 5
y - intercepts when y = 0 : 5x = -20 so : x = -4
7 and 20 are relatively prime (no common factor)
This is a backup question it would be great to state what question 3 was please
Answer:
B
Step-by-step explanation:
use the point (-5,3)
y-3=-(x-(-5)) = y-3= -(x+5)
