Given:
y-intercept of the graph: (0, 90)
zeros: 5 and 9
The equation that models the function based on the zeros given, is either
y = 90 (x-5) (x-9)
or
y= 2(x-5)(x-9)
try solving for the y-intercept of each function,
y = 90 (0-5) (0-9)
y = 4050
(0, 4050)
y = 2(0-5) (0-9)
y = 90
(0, 90)
therefore, the equation that models the function is y = 2(x-5)(x-9)
Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x=5,−2

Answer: 36% are not comedies
Step-by-step explanation:
32/50 = 64%
100 - 64 = 36
Answer:
The lower bound for a 90% confidence interval is 0.2033.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The lower bound for a 90% confidence interval is 0.2033.
Answer:
2
Step-by-step explanation:
0! + 1!
= !1 / 1 + 1!
= 1 + 1
= 2
