First, u do -9+8x-4+8
Then, U simplify. The answer is 8x-5
1. false because they have the same slope and y-intercept so they have infinite number of solutions
2. true
Answer:
<h2>$2479.5</h2>
Step-by-step explanation:
In this problem we will estimate her monthly earnings
given that she earns $13.05 per hour
and also given that she works for 190 hours in a month
then in a month, her earnings will be
=$13.05*190
=$2479.5
alternatively,
per week she works 47.5hours
in a week she will earn 13.05*47.7= $622.485
4 weeks make a month
then after one month her earning will be
$622.485*4= $2479.5
Answer:
yes
Step-by-step explanation:
A parolelogram is a rectangle and some rectangles have 4 right angles
Answer:
t = [ (x1' - x2' ) - d ] / SE . p < 0.05 suggests means are equal, p > 0.05 suggests means are unequal.
Step-by-step explanation:
Null Hypothesis [H0] : There is no difference between average estimates of two garages, M1 = M2
Alternate Hypothesis [H1] : There is difference between average estimates of two garages, M1 ≠ M2
Hypothesis can be tested by t test
t = [ (x1' - x2' ) - d ] / SE , where :-
x1' & x2' are sample means, SE = sqrt[ (s1^2/n1) + (s2^2 /n2) ] , d is the hypothesized difference between population means, and SE is the standard error ie 0 here
If the p value corresponding to calculated t value is < p value as per significance level (0.05) : We reject null hypothesis & state that M1 ≠ M2
If the p value corresponding to calculated t value > p value as per significance level (0.05) : We accept null hypothesis & state that M1 = M2
