Answer:

No

Step-by-step explanation:

To determine if the point (- 3, 5) is a solution to both equations.

Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.

x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True

- 2x + y = - 2(- 3) + 5 =  6 + 5 = 11 ← False

Thus (- 3, 5) is not a solution to the system of equations.

anyanavicka [17]

Answer:

Step-by-step explanation: You will substract the new value from the old value.

23-20

Now you will get the difference between them and divide that by the original amount.

3/20

This will equal 0.15 in which you now multiply by 100

Austin is a human resources executive for a technology company. He is deciding between two types of plans for vacation allowance
ElenaW [278]

The question requires that we have to state the hypothesis:

null hypothesis;H0: u1 < u2, the alternate hypothesis;H1: u1 > u2. The one tail test is what is to be used.

<h3>A. How to state the hypothesis</h3>

H0: u1 < u2

H1: u1 > u2

The one tail test statistic is what is to be used here

<h3>B. standard error </h3>

\sqrt{\frac{30.8}{17} +\frac{6.1}{15} }

= 1.49

The df = 17 + 15 - 2

= 30

test statistic = 18.9 - 17.4 / 1.49

= 1.007

We have the critical value on excel as T.INV(0.9,30)

=  1.310

E. At 0.1, we can conclude that  t-value (1.007) does not lies in the rejection area. We fail to reject the null hypothesis. Hence we conclude that the mean vacation with the unlimited plan is greater.
