B
Is the correct answer



Aleonysh [2.5K]3 years ago

Answer:

A. The interquartile range (IQR) for town A is 20 and it is greater than town B which has IQR = 10.

Step-by-step explanation:

<em>Interquartile range measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile. </em>

<em>Also, the end points of box plot shows the First and Third Quartile.</em>

Thus Town A has First Quartile = 20

Third Quartile = 40

⇒ IQR = 40 - 20 = 20

and, Town B has First Quartile = 35

Third Quartile = 45

⇒ IQR = 45 - 35 = 10

Also, <em>Standard deviation can't be calculate using Box- Plot.</em>

Thus, Option A is the only correct option.

At a shelter, 15% of the dogs are puppies. there are 60 dogs at the shelter. How many are puppies?
frutty [35]
So for this you need to find 15% of 60. There are a few ways to do this but I prefer to do it like this.

First, find 10% of 60. This can be found by dividing 60 by 10, because 100%/10% is 10.

This gives 10%=6

5% is half of 10%, so divide your answer for 10% (6), by 2.

This gives 5%=3

We needed 15%, so we add our 10% and 5% together, to get 9.

15% of 60 is 9, meaning there are 9 puppies.

Hope this helps!

The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?
Anestetic [448]

Answer:

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Step-by-step explanation:

Let

x -----> represent the measures of the seven same-size angles,

x/2 ----> represent the measure of the one that is "two times smaller."

we know that

The sum of internal angles of a polygon can be calculated as:

S=180^o(n-2)

where

n is the number of sides of the polygon

In this case

n=8 (octagon)

substitute

S=180^o(8-2)=1,080^o

so

The linear equation that represent this problem is

\frac{x}{2}+7x=1,080

solve for x

\frac{15x}{2}=1,080\\\\15x=2,160\\\\x=144^o

so

\frac{x}{2}=72^o

therefore

7 of the angles measure 144 degrees each and one angle measures 72 degrees

If 9/10 is multiplied by 8/9, will the product be greater than either of the two factors?
Goshia [24]
No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.
