Answer:
The width cannot be negative, so w = 9, l = 16.
Step-by-step explanation:
w = the width
l = w +7
A = l · w
A= w ( w + 7 )
144 = w2 + 7w
0 = w2 + 7w - 144
0 = ( w - 9 )( w + 16 )
The width cannot be negative, so w = 9, l = 16.
| x + 4 | = 5
x + 4 = 5 x + 4 = -5
x = 5 - 4 x = -5 - 4
x = 1 x = -9
solution : x = 1 and x = -9

Answer:
The appropriate hypothesis set for Andraya to test is:


Step-by-step explanation:
The makers of the game claim that the wheel has an equally likely probability of landing on each section.
That is, the makers claim that the probability of earning the grand prize is:

Andraya has played the game for several months and believes that the grand prize occurs less often than the game makers claim.
At the null hypothesis, we test if it happens as often as the makers claim, that is, the proportion is 0.125. So

At the alternate hypothesis, we test if it happens less ofter than the makers claim, that is, the proportion is less than 0.125. So

The appropriate hypothesis set for Andraya to test is:
