Answer:
3
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (- 1, 1)
d = 
= 
= 
= 
= 3
← exact value
≈ 6.71 ( to 2 dec. places )
The z-score tells you
the value is 0.02 standard deviations above the mean.
Start with

Divide both sides by -3

If the absolute value of a number is 4, that number can either be 4 or -4: we have the two solutions


Answer:
x=-16
Step-by-step explanation:
The given equation is:
x = 8a
which was written to find the value of x.
We have to find the value of x when the value of a is inserted as -2
So, putting the value
x = 8(-2)
x= -16
So the value of x when a = -2 is -16 ..
