You have test scores of 75 00 76 77. your math teacher will record your grade as mean median or mode. wich will give you the best grade ?

Median

You can't use the mode in here, since there are no repeated numbers. But You can use mean and median. If you use the mean, you will get 57. If you use the median, you will get 75.5. This means that the median will give you the best grade.

Explanation:

Mode: The most repeated number.

Median: The Middle number of statistics.

Mean: The average of all numbers.

The median will give you the best grade.

Step-by-step explanation:

The mean, as you might know, is the result of the result of dividing the sum of the grades by the number of grades, which is 4. The sum of the grades is 228. Since there are four grades, the sum should be divided by 4. When that is done, you should get a dividend (and a mean) of 57.

The median is the number in the exact middle of the data set. However, the problem comes when we find that there is an even number of numbers in the data set. When there is an even number of numbers in the data set, the mean of the two numbers in what would be the middle of the data set is the median. The two numbers in the middle of the data set are 75 and 76. The mean of those two numbers (which is the sum of the numbers divided by 2) is 75.5, and with that, you have your median.

The mode is the number that repeats itself the most times in the data set. Now, there is a problem. Every number in the data set appears once! But this problem is very simple to solve. There is simply no mode. It's not even going to be an actual number, it simply doesn't exist.

And with that, we have our mean of 57, our median of 75.5, and our nonexistent mode. The median is the highest grade, therefore the median will give you the highest grade.

Hope this helped!

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
