Mathematics
1 answer:
sergejj [24]3 years ago
5 0

Answer:

(x + 10)(x + 8)

Step-by-step explanation:

Given

x² + 18x + 80

Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)

The factors are + 10 and + 8 , since

10 × 8 = + 80 and 10 + 8 = + 18 , then

x² + 18x + 80 = (x + 10)(x + 8) ← in factored form

Use the given confidence interval limits to find the point estimate p^ and the margin of error E. 0.325
diamong [38]

Answer:

0.350

Step-by-step explanation:

Confidence interval = point estimate ± margin of error

Point estimate = Confidence interval - margin of error

To get the margin of error, we will take the average of the difference of the interval given. Given the confidence interval 0.325<p<0.375

Margin of error = 0.375-0.325/2

Margin of error = 0.050/2

Margin of error = 0.025

Using the interval of 0.375

Point estimate = 0.375 - 0.025

Point estimate = 0.350
