Answer:
69.5%
Step-by-step explanation:
A feature of the normal distribution is that this is completely determined by its mean and standard deviation, therefore, if two normal curves have the same mean and standard deviation we can be sure that they are the same normal curve. Then, the probability of getting a value of the normally distributed variable between 6 and 8 is 0.695. In practice we can say that if we get a large sample of observations of the variable, then, the percentage of all possible observations of the variable that lie between 6 and 8 is 100(0.695)% = 69.5%.
Answer:
$35.75
Step-by-step explanation:
100-35=65
.65 x 55 = 35.75
Determine the area of the circular region that can be reached by the radio station signal using the equation.
A = πD²/4
A is area and D is diameter. Using 3.14 as pi value.
A = (3.14)(120 mi)² / 4
A = 11304 mi²
Knowing that in each of the squared miles, 100 people live.
total population receiving the signal = 11304 mi² x (100 people / 1 mi²)
= 1,130,400
Thus, the answer is letter C.
