Answer: 339
Step-by-step explanation:
Since the prior estimate of population proportion is unknown , then we take p= 0.5
Given : Margin of error : E=0.07
Critical value for 99% confidence interval :
Formula for sample size :-
Hence, the minimum sample size required = 339
i.e. they need to survey 339 residents.
The answer is 10.
(a - b)² = a² + 2ab + b²
(-x - 5)² = (-x)² - 2 * (-x) * 5 + 5²
= x² + 10x + 25
Answer: 5 * x * a
Step-by-step explanation:
It’s algebra
Hey there!
For the beginning of the problem, I believe you meant to type "2 3/4" instead of "23/4". But to solve this, you can subtract the numbers 2 3/4 and 1/2 . . .
3/4 - 1/2 . . .
3/4 = 3/4
1/2 = 2/4
3 - 2 = 1
The denominator stays the same, so that leads you to the fraction 1/4 . . .
2 + 1/4 = 2 1/4.
2 3/4 - 1/2 = 2 1/4
You need 2 1/4 quarts of more broth to make the soup.
Hope this helps you.
Have a great day!
