There are 38 students in an elementary statistics class. on the basis of years of experience, the instructor knows that the time needed to grade a randomly chosen first examination paper is a random variable with an expected value of 6 min and a standard deviation of 6 min. (give answers accurate to 3 decimal place.)

p> q if you calculate p is100 q is 79

no not all of them.

step-by-step explanation:

some of them have a square base.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
