A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners

Vlad [161]

Answer:

D. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test

Step-by-step explanation:

Hello!

When planning what kind of hypothesis to use, you have to take into account any other studies that were made about that topic so that you can decide the orientation you will give them.

Normally, when there is no other information available to give an orientation to your experiment, the first step to take is to make a two-tailed test, for example, μ₁=μ₂ vs. μ₁≠μ₂, this way you can test whether there is any difference between the two stands. Only after having experimental evidence that there is any difference between the treatments is there any sense into testing which one is better than the other.

I hope you have a SUPER day!

The equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7

<h3>Trigonometry</h3>

From the question, we are to determine which of the given equations can be used to determine the measure of ∠A

In the diagram,

If ∠A is the included angle

Then,

Using<em> SOH CAH TOA</em>

Opposite = 9.4

Adjacent = 6.7

Thus,

tanA = 9.4/6.7

Hence, the equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7

A fruit basket weighing a total of 15 lbs. contains three types of fruit: apples, oranges, and pears. The apples weigh 4 1/2 lbs

frez [133]

Answer:

B is most likely the answer

Step-by-step explanation:

4 1/2 * 2= 9 so 15-9= 6

Pears weight is 6 Ibs and

4 1/2 *2 would make the most sense

In a class of P students, the average of test scores is 70. In another class the average test scores is 92. When scores of the t

Basile [38]

So, since averages are defined as:

$\frac{\sum_{k=1}^{P} P_k}{P}=70$

So, since P are the total number of elements and P_k is the P_kth student. This is saying if we sum over each student's score and divide it by the number of students, we should get P, which is true.

So, using that logic, the other class can be represented as:

$\frac{\sum_{k=1}^{N} N_k}{N}=70$
