Answer:

q= −4t+7u over 8r

Step-by-step explanation:

8qr+4t=7u

Step 1: Add -4t to both sides.

8qr+4t+−4t=7u+−4t

8qr=−4t+7u

Step 2: Divide both sides by 8r.

8qr

−4t+7u

Answer:

−4t+7u

The standard form of the equation of a parabola is y = x2 - 8x + 29. What is the vertex form of the equation?

Bess [88]

Y = x² - 8x + 29
y = (x² -8x +4²) + 29 -4² . . . . add and subtract the square of half the x-coefficient
y = (x -4)² + 13 . . . . . . . . . . . . simplify

The appropriate choice is
C. y = (x - 4)² + 13

Question:

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. If you want your sample estimate to be within 5 years of the actual mean with a confidence level of 97% , how many citizens should be included in your sample? Assume that the standard deviation of the ages of all the citizens in this community is 18 years.

Answer:

61.03

Step-by-step explanation:

Given:

Standard deviation = 18

Sample estimate = 5

Confidence level = 97%

Required:

Find sample size, n.

First find the Z value. Using zscore table

Z-value at a confidence level of 97% = 2.17

To find the sample size, use the formula below:
