Step-by-step explanation:
1/2 × height × base
1/2 × 6.3 × 8
6.3 × 4 = 25.2 ans.
therefore, area of the ∆ is 25.2 ft ².
Answer: 95% certain that true proportion of population "p" is contained in (0.604, 0.781)
Step-by-step explanation:
We know that a 95% confidence interval is a range of values that you can be 95% sure that true mean of the population or true proportion of population lies in it .
Given : The 95% confidence interval for p was calculated to be (0.604, 0.781).
It means that we are 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Hence, the correct interpretation for this interval :- 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Formula for the Minimum Sample size 
The least biased estimate for p and q is 1/2.

Thus



Answer:
102
Step-by-step explanation:
x = 180 - (4x - 2) - 78
x = 180 - 4x + 2 -78
5x = 180 + 2 - 78
5x = 104
x =
.
So, angle UTW is 4 *
- 2 +
= 5 *
- 2 = 104 - 2 = 102
