Answer: standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

Question 8 -

FinnZ [79.3K]

Answer:

Her wage on the 8th day is $105 ⇒ answer d

Step-by-step explanation:

* Lets explain how to solve the problem

- The average of set of data = The sum of data/the number of data

- The sum of data = the average of set of data × the number of data

∵ Cindy worked for 15 consecutive days

∵ She is earning an average wage of $91 per day

∴ Her total earning = 91 × 15 = $1365

∵ Her average earning during the first 7 days is $87 per day

∴ Her total earning in the first 7 days = 87 × 7 = $609

∵ Her average earning during the last 7 days is $93 per day

∴ Her total earning in the last 7 days = 93 × 7 = $651

- Her total earning in the 14 days is the sum of the earning in the

first 7 days and the earning during the last 7 days

∵ Her total earning in the 14 days = 609 + 651 = $1260

∵ Her total earning in the 15 days is $1365

- To find her wage on the 8th day subtract her wage of the 14 days

from her wage of the 15 days

∴ Her wage on the 8th day = 1365 - 1260 = $105

* Her wage on the 8th day is $105

Please help quick Solve for x.

Kamila [148]

Answer:

x = 3.75

Step-by-step explanation:

So, lets start with what we know.

Line = 180 degrees

Triangle = 180 degrees, a + b + c = 180

So, we can form the equations,

17x - 1 + <CDB = 180

-17x + 1 -17x + 1

<CDB = 181 - 17x

and

84 +7x + 5 + <CDB = 180

89 + 7x + <CDB = 180

-89 -89 + 7x

<CDB = 91 + 7x

Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other

181 - 17x = 91 + 7x

-91 +17x -91 +17x

90 = 24x

90 / 24 = 24x / 24

3.75 = x

x = 3.75

There, you have it, x is 3.75

X + y = 15 5x - y = 9 Elimination method (4, ? ) what number is the ?

vovangra [49]

The ? Is 11.

You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
