Answer:
A
Step-by-step explanation:
So we have the equation:
First, let's subtract 16 from both sides:
Now, let's divide both sides by 3:
Remember that with fractional exponents, we can move the denominator into the root position. Therefore:
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
Cube both sides. Since we're cubing, the plus-minus stays.
Add 4 to both sides.

So, our answer is A.
And we're done!
Answer:
Step-by-step explanation:
Garrett achieves a field goal is independent of each kick. Hence X no of kicks is binomial with p = 0.83, and q =0.17
No of trials 3
Hence X can take values as 0 ,1,2,3 and
, r=0,1,2,3
Using the above we obtain prob distribution as
X 0 1 2 3
P(X) 0.0049 0.0720 0.3513 0.5718
P(X>=2) =P(X=2,3,4) =0.9231

Z value for company B =
From z value probablility is more for company A as
P(Z>-2.22) >P(Z>2.89)
