We know w=-17. So we do:
w-4←Write the equation
-17-4←Input the number
-17-4=-21←Do the subtraction to find the answer.

=(-17) - 4
=(-17) + (-4)
=(-21)

<h3>1) $\frac{1}{2}$ </h3><h3>3) $\frac{1}{6}$ </h3><h3>5) $\frac{2}{3}$ </h3><h3 /><h2>Step-by-Step Explanation:</h2><h3 />

1.<em> </em>Find the probability of rolling less than a four.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Outcomes lower than four</u> = 1, 2, 3

Then to answer it you need the probability in the form of a fraction.

$\frac{3}{6}$ simplifies into $\frac{1}{2}$

2. Find the probability of rolling an even prime number.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Prime Numbers Through 1-6</u> = 2, 3, 5

<u>Even Prime numbers Through 1-6</u> = 2

So the probability in the form of a fraction.

3. Find the probability of rolling factors of 20.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5

So probabilty in the form of a fraction.

$\frac{4}{6}$ simplifies into $\frac{2}{3}$

We have seen that the standard deviation σ measures the spread of a data set about the mean μ. Chebyshev’s inequality gives an e

Salsk061 [2.6K]

Answer:

100

Step-by-step explanation:

First we find the mean of this set of data. We find the mean by finding the sum of data values and dividing it by the number of data values:

5+10+10+10+10+10+10+15 = 80

There are 8 data values; 80/8 = 10. The mean is 10.

To find the standard deviation, subtract the mean from each value; square the difference; add the squares; divide by the number of data values; and take the square root:

5-10 = -5; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 15-10 = 5

(-5)^2 = 25; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 5^2 = 25

25+0+0+0+0+0+0+25 = 50

50/8 = 6.25

√6.25 = 2.5

The standard deviation is 2.5.

This means two standard deviations, or 2σ, is 2(2.5) = 5.

This gives us μ-2σ = 10-5 = 5 and μ+2σ = 10+5 = 15.

Since all of our data is between 5 and 15, 100% is within two standard deviations of the mean.

Write fraction as mixed number

ANEK [815]

To write a fraction as a mixed number, we need to figure out how many times 3 will go into 19. Divide 19 by 3 to get our whole number.
19/3 = 6.
We have 6 0/3 as our mixed number so far, but we have 1/3 left over from the 19/3, since 18/3 = 6.
Add 1/3 to 0/3.
Your answer is 6 1/3.
I hope this helps!
