Answer:

C. She added 10.5 and 50, then multiplied by 6 to calculate the amount earned for 6 hours.

Step-by-step explanation:

Sherry earns an hourly wage plus a bonus for each day’s work.

She uses the equation 10.5h+50 to represent the total amount she earns each day, where h is the number of hours she works.

Lets check the equation for each hour.

For 1 hour:

10.5(1)+50

=> 10.5+50=60.5 dollars  (correct)

For 2 hours:

10.5(2)+50

=> 21+50=71 dollars      (correct)

For 4 hours:

10.5(4)+50

=> 42+50=92 dollars   (correct)

For 6 hours:

10.5(6)+50

=> 63+50=113 dollars    (wrong)

So, the 6 hours calculation is wrong.

Therefore, C is the right answer.

C. She added 10.5 and 50, then multiplied by 6 to calculate the amount earned for 6 hours.

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.

In a certain quiz that consists of 10 questions, each question after the first is worth 4 points more than the preceding questio
weqwewe [10]

Answer:

C. 26

Step-by-step explanation:

Let’s suppose that the first question is worth ‘’x’’ amount of points. Then the second question will be worth x+4, the third question x+8, the fourth question x+12, the fifth x+ 16, the sixth x+20, the seventh x+24, the eighth x+ 28, the ninth x+ 32, and the last one x + 36.

The sum of the points of all these questions is equal to 10x + 180. Since the quiz has a total of 360 points, then

10x + 180 = 360.

Solving for x we get:

X = 18.

This means that the first question is worth 18 points, the second one 22 points (18 +4), the third one 26 points(18+4+4), and so on.

Alexxx [7]

Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10
