Answer:
x+4= -2+4
x+4 = 2
Step-by-step explanation:
Answer:
(x, y) = (2, -1.5)
Step-by-step explanation:
x + 2y = -1
5x - 4y = 16
<=>
(2)x + (2)2y = (2)(-1)
5x - 4y = 16
<=>
2x + 4y = -2
5x - 4y = 16
<=>
7x = 14
<=>
x = 2
(*)x + 2y = -1
=> 2 + 2y = -1
=> 2y = -3
=> y = -1.5
=> (x, y) = (2, -1.5)
The correct answer is option C
Answer:
Check the explanation
Step-by-step explanation:
Going by the first attached image below we reject H_o against H_1 if obs.
here obs.T=1.879

we accept
at 5% level of significance.
i.e there is no sufficient evidence to indicate that the special study program is more effective at 5% level of significance.
1.
this problem is simillar to the previous one except the alternative hypothesis.
Let X_i's denote the bonuses given by female managers and Y_i's denote the bonuses given by male managers.
we assume that
independently
We want to test 
define 
now 
the hypothesis becomes

in the third attached image, we use the same test statistic as before
i.e at 5% level of significance there is not enough evidence to indicate a difference in average bonuses .
Jeremy will pay $41.05 interest.
We know that, Interest = PRT/100
where,
P = principal
R = rate
T = time
For given question, principal (P) = $325.18
interest rate R = 12 5/8%
= 12.625%
And period T = 1 year
We need to find the interest.
⇒ Interest = PRT/100
⇒ Interest = (325.18 × 12.625 × 1) / 100
⇒ Interest = 4105.3975 / 100
⇒ Interest = $41.05
Therefore, Jeremy will pay $41.05 interest.
