40 points fast For the following set of test scores, identify:

myrzilka [38]

Answer:

The measure of center would this student want his teacher to use is the

median $= {\bf 75}$

Mean $= {\bf 5}$ , Mode $={\bf 82}$ , Range $={\bf40}$ and Interquartile Range $= {\bf 32}$

Step-by-step explanation:

Given Data set $= 50,55,70,75,82,82,90$

Number of elements in data set $= 7$

To find Mean

The ‘Mean” is the average of a set of numbers.

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set.

Mean $= \frac{50 +55 +70 + 75 + 82 + 82 + 90} {7 }$

Mean $= \frac{504}{7}$

Mean $= 5$

Median

The “Median” is the middle value of a set of ordered numbers.

Therefore Median $=75$

Mode

The "Mode" for a set of data is the value that occurs most often.

It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set.

Therefore Mode $=82$

Range

The "Range" is the difference between the largest value and smallest value in a set of data.

Range $= 90-50$

Range $= 40$

Interquartile Range

The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.

The "Interquartile Range" is from Q1 to Q3:

To find the interquartile range of a set of data:

The cut the list into four equal parts

. The quartiles are the “cuts”

The interquartile range is the distance between the two middle sets of data

Interquartile Range $= Q_3-Q_1$

Interquartile Range $= 82-50$

Interquartile Range $= 32$

The sum of two numbers is 36. their difference is 4. determine the two unknown numbers.

Rasek [7]

So you know if a and b are the numbers that a+b=36 and a-b=4 so you can solve one I solved the second equation for a a=4+b and plugging that a value into equations gives you 4+b+b=36
This simplified to 4+2b=36
2b=32
B=16 so you know one number is 16 and you can plug it in to find a a-16=4 so a=20

Therefore the two numbers are 16 and 20

Which of the following is true regarding the angle shown?

Marat540 [252]

Answer:

Step-by-step explanation:

We know that A is not true because the angle is formed by rays, not line segments. We know this because the ends of the lines are arrowheads, which indicates that they are rays. You might be saying that A is true because BA and BC form the angle but actually, even if you removed points A and C, you would still have the angle. B is not correct because according to the diagram, the vertex is point B, not point A. The vertex of an angle is the common endpoint of the two rays that form the angle, therefore it would be point B. D is not correct because angles can have multiple names, the letters do not have to be in alphabetical order. Therefore, C is correct.
