A teacher writes the results of a test on the board: 7 students received A's, 10 students received B's, 18 students received C's, 4 students received D's, and 1 student received an F. The grade of C would represent which measure of central tendency? a. Mean b. Mode c. Median d. Standard deviation

Step-by-step explanation:

Given that  "A teacher writes the results of a test on the board:

7 students received A's, 10 students received B's, 18 students received C's, 4 students received D's, and 1 student received an F."

The mode is the most occurring  value in a data set.

In the given case, the frequency distribution was 7 A's, 10 B's, 18 C's, 4 D's and 1 F, since C is the most common grade,therefore it is the mode.

Only if the given was a normal distribution, the mode must be equal to the mean and the median.

In this case the median(middle term) is also C .

Hence C is the mode because it is the value that occurs most  in the given set of data.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
