Ajoint usa today/cnn/gallup poll in july 2000 indicated that of 832 white adults, 441 thought affirmative action has been good for the country and 308 thought it had not been good; the remaining 83 were undecided. test a hypothesis that a majority (> .5) of the white population think affirmative action has been good (at .01 significance level).

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
