The standard deviation of ages in Class A is 0.628 and the standard deviation of ages in Class B is 0.873. What can you tell about the classes from the standard deviations?

A: The kids in class A have more similar ages than class B because A's standard deviation is lower.

B: The kids in class A have higher ages than those in class B because A's standard deviation is lower.

C: The kids in class A have lower ages than those in class B because A's standard deviation is lower.

D: The kids in class A have less similar ages than class B because A's standard deviation is lower.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
