Answer:
95% confidence interval for the true fraction p is (0.426, 0.488)
Step-by-step explanation:
Confidence Interval can be calculated using p±ME where
- p is the sample proportion (
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion (0.457)
- N is the sample size (1000)
then ME=
≈ 0.031
Then 95% confidence interval would be 0.457±0.031 or (0.426, 0.488)
Step-by-step explanation:

The zeros and intercepts of the polynomial m^2 + 5m + 4 will be different.
<h3>Intercepts and zero of a function</h3>
A quadratic function is a function that has a degree of 2.
Given the following equation
f(m) = m^2 + 5m + 4
The x-intercept occurs at the point where f(m) is zero and same is applicable to the zeros of the function.
This shows that the zeros and intercepts of the polynomial m^2 + 5m + 4 will be different.

The solution to x + 8.5 = 64.5 is 56.
x + 8.5 = 64.5
- 8.5 - 8.5
---------------------------
x = 56
It is just asking to find the sum of interior angles
So follow this rule 180(n-2)
180(5-2)
180(3)= 540
So in another words: a+b+c+d+e=540
