The height is 6tan(60)=10.39 then plug that in to trapezoid area formula
(11+6+15)/2*10.39=166.24
Answer:
The right answer is:
a.H0: μd = 0; H1: μd > 0
Step-by-step explanation:
The claim that want to be tested is that the sales were significantly increased after the commercial, indicanting that the advertisement campaign was effective.
This claim is usually expressed in the alternative hypothesis as it has to have enough evidence to prove that it is true.
Then, the alternative hypothesis H1 should state that the difference (sales after - sales before) is higher than 0.
The null hypothesis would state that the difference is not significantly different from 0, or, in other words, that the sales are the same before and after and that the variation is due to pure chance.
Then, the null hypothesis H0 would state that the difference is equal to 0.
The right answer is:
a.H0: μd = 0; H1: μd > 0

<u>Solution-</u>
When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.
When the line are parallel the corresponding angles are equal in measurement.
As m and n are parallel line, so




Answer:
The ending cash balance is $12,800
Step-by-step explanation:
This is an addition and subtraction problem. We begin with the initial cash balance of $6,800. Next we are <u>"provided"</u> cash from various activities of $37,000. Based on the word used we can tell that this means we have to <em>add </em>this to our initial balance like so,

Now our balance is $43,000. Next we are told that Net Cash <u>"used"</u> in investing activities is $13,600 and <u>"used"</u> in financing activities is $17,400. Based on this word we can tell that this money is being <em>subtracted</em> from our balance.

Finally, we can see that the ending cash balance is $12,800
