Answer:
The point estimate is 0.88
Step-by-step explanation:
Given
-- sample size
-- adults who think future health of social security is a major economic concerm
Required
Determine the point estimate
This is calculated as:
![\hat p= \frac{x}{n}](https://tex.z-dn.net/?f=%5Chat%20p%3D%20%5Cfrac%7Bx%7D%7Bn%7D)
![\hat p= \frac{1760}{2000}](https://tex.z-dn.net/?f=%5Chat%20p%3D%20%5Cfrac%7B1760%7D%7B2000%7D)
![\hat p = 0.88](https://tex.z-dn.net/?f=%5Chat%20p%20%3D%200.88)
<em>The point estimate is 0.88</em>

Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
s ×
= 4
( divide both sides by
)
s = 4 → A
Answer:
(m + 7)(m + 5)
Step-by-step explanation:
Factor, find factors of m² & 35 that, when combined, will give 12m:
m² + 12m + 35
m 7
m 5
(m + 7)(m + 5) is your answer.
Check: Use the FOIL method to check.
(m)(m) = m²
(m)(5) = 5m
(7)(m) = 7m
(7)(5) = 35
Combine like terms:
m² + (5m + 7m) + 35 = m² + 12m + 35 √.
