Answer:
$7.25 at part-time job
$9.00 every time lawn mowed
so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line. with dotted
Answer:
GCF: 2x
Factored: 2x(x+3)(x-3)
Step-by-step explanation:
Answer:
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Step-by-step explanation:
Given that a sample of 1300 computer chips revealed that 27% of the chips do not fail in the first 1000 hours of their use, as against company literature of 29%
To test this we create hypotheses as
(left tailed test at 10% significance level)
p difference = -0.02
STd error of p =
Test statistic = p diff/std error = -0.1587
For 10% significance level for right tailed test we can reject H0 if
test statistic <-1.645
Decision rule for rejecting is
reject H0 is test statistic <-1.233
G = F(4x+5)/ 3x-2
C = (4x+5) (3x-2)/ 24C
F = 3x-2/C
True because of 15 and 20
