So the 3 at the top indicates that you have to multiply the number(fraction) by itself three times.
It is called an exponent.

So it will be “5/6 times 5/6 times 5/6”
And im not sure how to multiply that so according to the internet its 0.5787937, Round that and its 0.579. They didnt show a fraction form.

Answer: 2

Step-by-step explanation:

Slope is rise over run. So if we look at the points (1,1) and (0,3), you can see that it goes up by 2 units and over one unit, leaving you with "2/1", which is equivalent to 2.

P.S I just finished a assignment on this lol

the answer is c I’m pretty sure

Person A spends $9.80 on gas. The car drives 27 miles per gallon and the driver drives 135 miles.

Person B's car gets 29 miles per gallon and spends $14.28 on gas to drive 203 miles.

If person A spends $13.72 on gas at the same rate, and person B spends $16.32 on gas, what is the difference in the amount of miles the cars can travel before running out of gas?

Answers

I think the answer is $72.52

Car B can drive 43 more miles than car A before running out of gas

Car A= $1.96 per gallon
Car B= $2.04 per gallon

Car A- 7 gal. x 27 mi./gal= 189 mi.
Car B- 8 gal. X 29 mi./gal= 232 mi.

232-189= 43

Suppose we know that a confidence interval is (27,35), with a margin of error of 4. Find the sample mean (x¯).

Answers

May u explain it alittle more im just confused

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

The sample mean is 31.

What is a mean?

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Confidence interval = (27,35).

The margin of error = 4.

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

Now,

The sample mean = x

x + 4 = 35 ____(1)

x - 4 = 27 _____(2)

From (1) we get,

x = 35 - 4 = 31

From (2) we get,

x = 27 + 4

x = 31

Thus,

The sample mean is 31.
