(1) Area: 35 y² +13y-12​
Fiesta28 [93]

Answer:

35y2+13y−12

                       =35y2+28y−15y−12

                       =7y(5y+4)−3(5y+4)

                       =(7y−3)(5y+4)

Therefore, the possible length and breadth are 7y-3 units and 5y+4 units

Read the following statement: If the sum of two angles is 90°, then the angles are complementary. The hypothesis of the statemen
xeze [42]
Hey there!

It seems your problem is simply trying to rewrite the sentence.

Let's rewrite our sentence, from the phrase after the comma to the phrase before the comma.
Essentially, we are just flipping the sentence structure.

It should be this:
The two angles are complementary if the sum of the two angles are 90 degrees.

Let's take a good look at our answers.

A.) There are two angles.
While this is a true statement, it's a little too vague to understand. We can eliminate this answer choice.

B.) The sum of two angles is 90 degrees.
This is also a true statement, but it doesn't describe what type of angles sum to 90 degrees, so we can eliminate this as well.

C.) The angles are complementary.
This is similar to answer choice A. It's a little too vague for specific understanding. We can eliminate this answer choice.

D.) Angles are complementary if their sum is 90 degrees.
This is an accurate statement, and provides details to support it's claim, also rewriting the original sentences into one properly. This answer choice is correct.

Your answer is D.)

I hope this helps!

A researcher wants to conduct a study to determine whether exercising for 15 minutes helps to improve memory in patients with ea
Cerrena [4.2K]

Answer:

Part A

The proposed design is shown in the explanation below

Part B

We conclude after making our decision that :

Type II Error is more serious because in this error ,the clinic will not offer free service to patients, which will be very effective.

Step-by-step explanation:

Part A:

We will have to divide 150 patients into 2 groups:

One group, of 75 patients, is control group without exercising.

The other group of 75 patients with exercising for 15 minutes.

Then we will test if the  memory of the other group is more than that of the control group.

Part B

H0: There is no difference in mean improvement

HA: Alternative Hypothesis: There is difference in mean improvement'

Type I Error: Rejection of a true null hypothesis.

Assuming  in reality there is no difference in mean improvement. But, due to hypothesis testing, we wrongly conclude that there is difference in mean improvement.

Then Type I Error is committed in this case. The result of this error is that only if the clinic will offer this exercise as a free service, which is not at all effective.

Type II Error: Retaining a false null hypothesis.

Assuming in reality there is difference in mean improvement. But due to hypothesis testing, we wrongly conclude that there is no difference in mean improvement.

Then Type II Error is committed in this case.

The result of this error is that the clinic will not offer this exercise therapy as a free service,which is very much needed.

Therefore;

Type II Error is more serious because in this error ,the clinic will not offer free service to patients, which will be very effective.
