Answer:

12 is mean     11 is median     range is 14

Step-by-step explanation:

For the Mean

Add all the numbers up

16 + 9 + 20 + 10 =55

12 + 6 + 8 + 15 = 41

55 + 41 = 96

There are 8 numbers so we divide by 8

96/8 = 12

Range is Smallest number minus biggest so 20 - 6 = 14

Answer:

Mean: 12

Median: 11

Mode: No Mode

Range: 14

Step-by-step explanation:

Mean:

- To calculate the mean, add up all the numbers, and divide by the number of numbers there are.

16 + 9 + 20 + 10 + 12 + 6 + 8 + 15 = 96

96 divide by 8 = 12

Median:

- Order the numbers from least to greatest, and find the middle number!

6, 8, 9, 10, 12, 15, 16, 20

Since there is NO middle number, because there are 8 numbers, add the two numbers (10 + 12), and divide by 2.

10 + 12 = 22

22 divided by 2 = 11

Mode:

The mode is the number that appears most often. Since NO number appears more than once, there is no mode.

Range:

- The range is the difference between the highest number and the lowest.

Highest Number: 20

Lowest Number: 6

20 - 6 = 14

Hope this helps!

1g-1.5=-4g-4 (distribute 1/2 and -4 inside their respective parenthesis)
1g=-4g-2.5 (add 1.5 to -4)
5g=-2.5 (add 4g to 1g)
g=-0.5 (divide both sides by 5)

Viefleur [7K]
Hello!

There are only six was to to role a number less than four. 1 and 1. 1 and 2. 2 and 1. 1 and 3. 2 and 2. 3 and 3 and 1.

The first number on the die could be 1, and the second die could have a probability of rolling the second number on it. Giving us a probability of 1/6.

We can subtract the calculated probability from rolling less than four from 1 to find the probability of rolling more than 5:

1 - 1/6 = 5/6

So, your answer should be D 5/6.

A plant manufactures part whose lengths are normally distributed with a mean of 16.3 centimeters and a standard deviation of 2.5
EastWind [94]

The probability that the plant manufactures a part between 10.8 and 12.8 centimeters 13%

<h3>How to find the probability that the part is between 10.8 and 12.8 centimeters</h3>

The probability is solved z scores, this measures the amount of standard deviation sample X is from mean. the formula is below

z = (X - μ) / σ

<u>Definition of variables</u>

mean, μ = 16.3 centimeters

standard deviation, σ = 2.5 centimeters

X = 10.8 and 12.8 centimeters

z score, z

substituting into the formula

for X = 12.8 centimeters

=  (X - μ) / σ

= (12.8 - 16.3) / 2.5

= -1.4

the p value for z of -1.4 = 0.161513

for X = 10.8 centimeters

=  (X - μ) / σ

= (10.8 - 16.3) / 2.5

= -2.2

the p value for z of -2.2 = 0.027807

the probability is calculated as below

0.161513 - 0.027807= 0.133706

= 0.13

=13%
