Answer:

75


Step-by-step explanation:

The mean [average] of a set of data is "the sum of all the numbers divided by the number of numbers".

<em>How many numbers are in the data set?</em>

<em>15</em>

<u>So we simply add all of them up and divide by sum by 15.</u> Doing so gives us the mean:

Mean = \frac{90+70+63+98+95+32+54+89+84+80+68+71+77+71+83}{15}=\frac{1125}{15}=75

The mean is 75

How do you use a number line to find 3/4 times 2/5
Verizon [17]

Answer:

First, you need to find the number 2/5 on the number line.

Now, you want to find (3/4) times (2/5)

Then the distance between 0 and the point you found earlier needs to be divided into four equal parts (because the denominator is 4)

sAnd because we have the factor (3/4), with a numerator equal to 3, we move from the origin 3 of these parts to the right, the point at where you arrived is the point (3/4)*(2/5)

Another way, which should give you the exact same point, is:

First locate the point (3/4) on the number line.

Now, you want to find (3/4) times (2/5)

The distance between zero and the denominator needs to be divided into 5 parts (because the denominator is 5)

Because the numerator is 2, you need to move, from the origin, two of these parts to the right.

The point where you end is the product (3/4)*(2/5)
