Answer:
Slope: 2x
Y-intercept: -4
First we need to convert pt into qt
1qt = 2pt
That means that 50 pt is:
50/2 = 25 qt
And now we convert qt to L
25/1.06 = 23,6 L
Answer is A) 23,6 liters
Answer is -7
Plug 4 in for g(x) and solve to get x=-7.Plug x=-7 in for f(x).
Answer:
0.9812
Step-by-step explanation:
Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds
For a sample of 9 people std error of sample would be
Thus we find that sample mean is N(175, 12)
The plane will lift safely if sample average <200 pounds
i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)
=
~0.981
