Answer:
we arrive at the conclusion that the new employee installs the vertical blinds faster on average.
Step-by-step explanation:
null hypothesis; m₁-m₂ =0
alternative hypothesis; m₁-m₂<0
Given the information in this question, we first have to solve for the t statistic
t = -7.018
the degree of freedom = n₁+n₂-2
= 10+10-2
= 18
Alpha α = 0.05
from these results the t critical value = -1.734
because the test statistic -7.018 < -1.734,
at 0.05 level of testing, we arrive at the conclusion that the new employee installs the vertical blinds faster on average than the veteran.
Answer:5X+2=4X-9\quad :\quad X=-11
Step-by-step explanation:
5X+2=4X-9
5X+2-2=4X-9-2
5X=4X-11
5X-4X=4X-11-4X
X=-11
Answer:
i'm pretty sure that it's y=-2x+1
Step-by-step explanation:
first we solve for the slope of the line:
we have the points (-1,3) and (3,-5). So we write an equation like so:
<u>3 - -5</u>
-1 - 3
3/-1 - -5/3. solving that, you get 8/-4, and 8 divided by -4 is -2, so thats our slope.
now all we've got to do is get the y intercept. the way i found it was i graphed the line, put a dot on the points that we have ( (-1,3) and (3,-5) ) and you <em>should</em>
get 1 as the point on the y axis. again, i myself am not a pro or anything so if its not the correct answer i am so sorry. <3
Answer:
thanskkkkss broo!!
Step-by-step explanation:
We know, Distributive property tells: a(b + c) = ab + bc
So, 9.78(4.3x + 5.15) = 42.054x + 50.367
In short, Your Answer would be Option B
Hope this helps!
