This question can be solved by:
\frac{8.3}{100} =  \frac{35,600}{x}

Cross multiply to get: 8.3x = 3,560,000

To let the x stand along (since you are finding the x value), divide 8.3 to both sides of the equal sign.

\frac{8.3x}{8.3} =  \frac{3560000}{8.3}

Simplify to get the answer.

Find the mean and standard deviation for the set of data.
dem82 [27]

The mean and standard deviation for the set of data will be 16 and 5.87. Then the correct option is A.

<h3>What is a standard deviation?</h3>

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

The set of data is given below.

16, 22, 8, 5, 20, 18, 14, 17, 24

The mean of the data set will be

μ = (16 + 22 + 8 + 5 + 20 + 18 + 14 + 17 + 24) / 9

μ = 144 / 9

μ = 16

Then the standard deviation of the data set will be

\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}} \\\sigma = \sqrt{\dfrac{(16 - 16)^2 +(22 - 16)^2 + (8-16)^2 + ......+(24-16)^2  }{9}} \\\sigma = \sqrt{\dfrac{310}{9}}\\

Simplify the expression further, then we have

σ = √34.44

σ = 5.87

The mean and standard deviation for the set of data will be 16 and 5.87.

Then the correct option is A.

More about the standard deviation link is given below.

The manager of music is giving away 255 music downloads at its grand opening event.
Andreas93 [3]

30 people will receive 1 music download each.

<u>Solution: </u>

Given, the manager of music is giving away 255 music downloads at its grand opening event.

The manger gave the greatest possible number of music downloads to each of the first 75 customers,

Now, suppose, manager gave 4 downloads each for first 75 customers.

Then, total downloads = 75 x 4 = 300 downloads, which is greater than 255, so giving 4 to 1st 75 is not possible.

Now, suppose, he gave 3 to each customer, then total downloads = 75 x 3 = 225, it is possible

So, manager will give 3 downloads each to 1st 75 customers.  

Then remaining downloads = 255 – 225 = 30 downloads, then 30 people can use them.

Hence, 30 people will receive 1 music download each.

klasskru [66]

Answer:

Step-by-step explanation:

1 3/10 x 18

(1 x 10 +3)/10 = 13/10

13/10 x 18 = (13 x 18) / 10 = 234/10 = (234/2) / (10/2) = 117/5 = 23 2/5 (a fraction is a division)
