Identify the response variable and whether the setting involves a single sample, a matched pairs, or two independent samples.
Helga [31]

Answer:

1. single sample design

2. matched pairs

3. two independent samples.

Step-by-step explanation:

the response variable is known as the dependent variable, it is the variable that the researcher is interested i finding. the response variable is the x variable that responds to changes in the independent variable.

1.

In this question the researcher has only one sample that is the specimen. that is the reference specimen that she obtained. Therefore it is a single sample design.

the response variable here is the measurement of concentration.

2. In this question we have two pairs, men and women. The researcher is interested in comparing attitudes as she interviews them. so response variable is attitude or behavior

3. this is a 2 independent sample design. The researcher is using two different methods to test and their average is being compared.

Find the value of x.<br> Right triangle: Hypotenuse is 11, base is x, angle is 22 degrees.
kirill [66]
We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:
cos(22) =  \frac{x}{11}

We need to solve for x, so let's isolate it:
x = 11cos(22) = 10.2

So, x = 10.2 units

Work the following problem
neonofarm [45]

Answer:

Option B is the correct answer.

Step-by-step explanation:

Given

List Price=$720

The percentage of discount=13%

In order to find the amount of discount, 13% of the amount has to be calculated. To calculate 13% , the amount is multiplied by 13/100.

Amount of discount=13% of list price

=720*13/100

=720*0.13

=$93.60

The amount of discount is $93.6..

What has to be true for the triangles to be congruent?
natita [175]

Answer:

Step-by-step explanation:

Argument

I think the answer is A = N or D. It that is true, then M = C because all three angles are equal which gives similarity. But there is a side involved. OM = CB. Therefore the two triangles are congruent by ASA

Answer

ASA
