Expand = 2⋅2⋅x+2⋅3−(2⋅x−2⋅2)
Simplify = 10+2⋅x
To solve this problem, we make use of the z statistic.
The formula for the confidence interval can be calculated using the formula:
Confidence Interval = p ± MOE
where,
p is the portion of girls = 278 / 556 = 0.5
MOE is the margin of error
We calculate the margin of error using the formula:
MOE = z * sqrt[p (1 – p) / n]
From the standard distribution tables, the value of z at 99% confidence is:
z = 2.58
Therefore the MOE is:
MOE = 2.58 * sqrt[0.5 (0.5) / 556]
MOE = 0.055
Therefore the confidence interval is:
Confidence Interval = 0.5 ± 0.055
Confidence Interval = 0.445, 0.555
0.445<p<0.555
Answer:
Option D.
Step-by-step explanation:
-If the attached graph shows the distance above sea level to which Bethanie's leads as a function of time, then we can observe that after having elapsed 8 minutes Bethanie's is a distance of 0 from sea level.
The graph shows that the value of B(t) is always less than 1 during the 8 minutes of travel.
-On the other hand, the function 
that models the distance above sea level that Mike drives as a function of time, shows us that after 3 minutes the distance M(t) begins to increase rapidly until at t = 8 minutes:
.
Therefore the correct option is D
The person who leads to the highest elevation is Mike.
