Answer:
6 feet
Step-by-step explanation:
You are basically finding the perimeter of this rectangle.
2+2+1+1 = 6
7.43: Let denote the random variable for height and for the sample mean. Then if is the mean of
So the probability that the difference between the sample and population means does not exceed 0.5 inch is
per the empirical or 68/95/99.7 rule.
7.44: For a sample of size <em>n</em>, the sample standard deviation would be . We want to find <em>n</em> such that
Comparing to the equation from the previous part, this means we would need
so a sample of at least 157 men would be sufficient.
Answer:
8/17
Step-by-step explanation:
The sine is the opposite side divided by the hypotenuse:
sin(angle) = y/√(x²+y²) = 8/√(8²+15²) = 8/√289
sin(angle) = 8/17
Answer:
y=1
x=4
hope this helps!
if you graph these equations, they will intersect at (4,1). They look very short because they are vertical and horizontal.
Step-by-step explanation:
Since they’re in the same place you would do for 4 X -3 equals 115 and take it from there then you would find your answer and you may have to subtract it by 180
