For this case we have the following expression:
(6.21 + 0.93) + 0.07
We apply the associative property of the addition to rewrite the expression.
This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.
We have then:
6.21 + (0.93 + 0.07)
Answer:
6.21 + (0.93 + 0.07)
Associative property.
<span>Last
year, the average math SAT score for students at one school was 475. The
headmaster then introduced a new teaching method hoping to improve scores. This
year, the mean math SAT score for a sample of students was 491. The headmaster
concluded that the new teaching method produces higher SAT scores. The problem
with reporting results this way is voluntary response. The information of how
the teaching method isnot mentioned.</span>
Answer:
A stadium has 49000 seats.
Seats sell for $25 in Section A, z
$20 in Section B,-------------------x seats
$15 in Section C. ------------------y seats
(x+y)=z
25(x+y)+20x+15y=1052000
25x+25y+20x+15y=1052000
45x+40y=1052000
/5
9x+8y=210400------------------1
2x+2y=49000
/2
