Answer:
The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
Step-by-step explanation:
Mean = 
Population standard deviation =
Sample size = n =25
Sample mean = 
We are supposed to find the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e.

Z=5.83
P(Z<52)=0.9999974

Hence the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
X^2+4+10=0
x=(-4(+/-)root16-40)/2, so we now know that the zeros are imaginary, because you can't square root a negative number and 16-40 is -24
so the two roots are…
-2+iroot6 and -2-iroot6
Y = -1.33 * x - 3
y = -1.33 -3 *x
y = -4.33 *x
