Answer:

$8/mile

Step-by-step explanation:

Total distance walked was 2 1/4 mi + 5 1/2 mi = 7 3/4 mi. Please note: you must use the " / " symbol to indicate division; "2 1 4" is unclear.

$62

Unit rate = $ per mile = --------------- = $8/mile

In an article about disinflation, various investments were examined. The investments included stocks, bonds, and real estate. Su

kykrilka [37]

Answer:

Step-by-step explanation:

Using the formula for calculating the confidence interval to estimate an interval for the mean rate of return on all real estate investments with 95% confidence;

Confidence Interval = xbar±(Z*S/√n)

xbar is the mean = 20%(assumed since we are not given)

n is the sample size = 200

S is the standard deviation = 2.25%

Z is the Z score at 95% confidence interval = 1.960

Confidence Interval = 20±(1.96*2.25/√200)

Confidence Interval = 20±(1.96*2.25/14.14)

Confidence Interval = 20±(1.96*0.159)

Confidence Interval = 20±0.312

Confidence Interval = (20-0.312, 20+0.312)

Confidence Interval = (19.688, 20.312)

Hence the interval for the mean rate of return on all real estate investments with 95% confidence is 19.688<x<20.312.

This means that the minimum rate of return on investment is 19.688% and the maximum rate of return on investment is 20.312%.(assuming 20% as the mean)

Solve the inequality for y.<br> x + 8y < 16

RoseWind [281]

To solve for y, you need to isolate/get the variable "y" by itself in the inequality:

x + 8y < 16 Subtract x on both sides

x - x + 8y < 16 - x

8y < 16 - x Divide 8 on both sides to get "y" by itself

$\frac{8y}{8}$
