Answer:

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.

A store is having a sale on jelly beans and trail mix. For 8 pounds of jelly beans and 4 pounds of trail mix, the total cost is

aleksley [76]

Make this on form of a simultaneous equation:

assume jelly beans is J and trail mix is T

8J+4T=21
3J+2T=9
then solve

multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])

24J+12T=63
24J+16T=72

Subtract

-4T=-9
T=0.44

then substitute the T to any one of the equation

3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71

therefore, jelly beans= $2.71 and trail mix=$0.44
