Mathematics
1 answer:
alisha [4.7K]3 years ago
8 0

Answer:

D

Step-by-step explanation:

Mean tells us the average (in this case, total marks/ total number of students).

Standard deviation tells us the spread of a set of data from its mean (how much it deviates from the mean).

Thus, standard deviation can be used to determine the consistency of a data. <u>The smaller the standard deviation, the more consistent the data is</u>.

Since 4S has the smallest standard deviation of 1, it shows the most consistent achievement in the test.

vovikov84 [41]
A = {1, 3, 5, 7, 9}
B = {2, 4, 6, 8, 10}
C = {1, 5, 6, 7, 9}

(B ∪ C) = {1, 2, 4, 5, 6, 7, 8, 9, 10}
so
A ∩ (B ∪ C) = {1, 5, 7 , 9}

Martin was given this expression to simplify: 23x + xy – y + 3y + 5 – 20x + 6xy He simplified the expression to: 43x + 7xy −3y W
tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

23x + xy - y + 3y + 5 - 20x + 6xy = 23x - 20x + xy  + 6xy -y + 3y + 5

                                                     = 3x + 7xy + 2y + 5

Errors:1) The combined coefficients of the x terms should be 3x, not 43x

2) The coefficients of the y terms have been multiplied.

3) The constant was left off.
