Answer:

A. 8/3

Step-by-step explanation:

Type each fraction into a calculator. (or use long division if you aren't allowed a calculator. I can't explain long division in a brainly comment there isn't enough flexibility)

8/3=2.666666

6/4=1.5

12/5=2.4

14/8=1.75

Answer:

A. 8/3

Step-by-step explanation:

1. Let x = 2.666667 - equation (1)

2. The repeating digit is 6.

3. Place the repeating digit to the left of the decimal point.

In this case, move the decimal point 1 place to the right by multiplying it by 10.

Thus,

(x = 2.666667) * 10

10x = 26.66667 - equation (2)

4. Subtract Eq.(1) from Eq.(2)

10x - x = 26.66667 - 2.666667

9x = 24

divide both sides by 9

x = 24/9 = 8/3

A student has $1 bills and $5 bills in his wallet. He had a total of 15 bills that are worth $47. How many of each type does he

Mrrafil [7]

Total number of $1 bills=7

Total number of $5 bills=8

Further explanation:

Given

Let x be the number of $1 bills

and

y be the number of $5 bills

Then according to the given statements

x+y=15

x+5y=47

From first equation:

$x+y=15\\x=15-y$

Putting x=15-y in second equation

$x+5y=47\\15-y+5y=47\\4y=47-15\\4y=32\\\frac{4y}{4}=\frac{32}{4}\\y=8$

Putting y=8 in first equation

$x+8=15\\x=15-8\\x=7$

Hence,

Total number of $1 bills=7

Total number of $5 bills=8

Harman [31]

People often draw hypothesis in research. Based on executing the test in Question 5, We reject the null hypothesis; the mean delivery time is different for every day of the week.

<h3>Why do we reject the null hypothesis?</h3>

Note that if the p-value of an experiment (Like the one above) is less than or found to be equal to the significance level of your test, one can reject the null hypothesis.

By that, we known that the data is in favors the alternative hypothesis. Hence the results gotten by you are statistically significant. If your p-value is found to be greater than your significance level, you then fail to reject the null hypothesis.
