To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
Answer:
It is the same answer, Because b is the same as a but in fraction form, and c is the same as b but in improper fraction form, so that means they are the same answer

Answer:
(-4qr)^4
Step-by-step explanation:
(-4qr)(-4qr)(-4qr)(-4qr)
There are 4 sets of -4qr being multiplied together
(-4qr)^4
