2(3)x2-(-2)?
if that’s the problem then it’s
12x2-(-2)
24+2 = 26!
Answer: A. Mean of sampling means 
Standard deviation of sampling means =
B. The probability that your sample has mean less than 165 is 0.1492 .
Given : The distribution of blood cholesterol level in the
population of young men aged 20 to 34 years is close to normal with
mean
Mg/dl and standard deviation
mg/dl.
Sample size : n= 150
Let
sample mean values.
A. The mean and the standard deviation of the distribution of the sampling means would be :
Mean of sampling means =
Standard deviation of sampling means = 

The probability that your sample has mean less than 165 would be

Hence , the probability that your sample has mean less than 165 is 0.1492 .
Answer:
3.36
Step-by-step explanation:
.20 x 2.80 = .56
2.80 + .56 = 3.36
In y=Mx+b, m is the slope (and b is the y-intercept). Therefore, the slope of that line is -4
Answer:
slope = 0
Step-by-step explanation:
y = -
is the equation of a horizontal line parallel to the x- axis.
Since it is parallel to the x- axis the slope = 0
Thus any line parallel to it will have a slope = 0
