Hi there!

Since there is a 1/6 chance of rolling a 6, we can just divide 48 by 6 and subtract it from 48:

48 / 6 = 8
48 - 8 = 40

So, the amount of times you would not roll a 6 is 40 times. 

Hope this helps!

Height, in meters, is measured for each person in a sample. After the data are collected, all the height measurements
charle [14.2K]

Answer:

(E) The z-scores of the height measurements

Step-by-step explanation:

Mean is given by

\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)=\frac{x_{1}+x_{2}+\cdots +x_{n}}{n}

Where,

n = Number of people

x_{i} = The heights of people

When converting m to cm the mean would be

\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)\times 100

So, the mean would change

The median gives us the middle data value when the data values are in ascending order.

So, the median would change

Standard deviation

s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}(x_i-\bar{x})^2}

When converting to centimeters

s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}\left((x_i-\bar{x})\times 100\right)^2

Hence, the standard deviation would change

When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.

The z score is given by

z=\frac{x-\mu}{\sigma}

where,

x = Data point

\mu = Mean

\sigma = Standard deviation

When converting to centimeters

z=\frac{(x-\mu)\times 100}{\sigma\times 100}\\\Rightarrow z=\frac{x-\mu}{\sigma}

Hence, the z score would remain the same

Fractional Equations Help with steps
Sliva [168]

Answer:

see explanation

Step-by-step explanation:

(e)

\frac{2x-1}{3} - \frac{3x-1}{4} = 1

Multiply through by 12 to clear the fractions

4(2x - 1) - 3(3x - 1) = 12 ← distribute parenthesis and simplify

8x - 4 - 9x + 3 = 12

- x - 1 = 12 ( add 1 to both sides )

- x = 13 ( multiply both sides by - 1 )

x = - 13

---------------------------------------------------------------

(f)

\frac{3m}{4} - 5 = 24 ( add 5 to both sides )

\frac{3m}{4} = 29 ( multiply both sides by 4 )

3m = 116 ( divide both sides by 3 )

m = \frac{116}{3}

--------------------------------------------------------------

(g)

\frac{5(y+2)}{2} - \frac{4(y+1)}{3} = 3

Multiply through by 6 to clear the fractions

15(y + 2) - 8(y + 1) = 18 ← distribute parenthesis and simplify

15y + 30 - 8y - 8 = 18

7y + 22 = 18 ( subtract 22 from both sides )

7y = - 4 ( divide both sides by 7 )

y = - \frac{4}{7}
