Answer:
x= -7
Step-by-step explanation:
1/2(4-6x)=23
Take1/2 of the numbers in the (). It will be 2-3x.
2-3x=23 subtract 2 from both sides to get x by itself
-3x=21 now divide the 21 by -3
x= -7
Y intercept is (0,-0.7) and X intercept is (-1.2 ,0)
Answer: a) 27.5, b) 5.33.

Since we have given that

and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is

The standard deviation of the distribution of sample means is

Hence, a) 27.5, b) 5.33.
