Tell whether the relation is a function. Explain.

Answer:

Step-by-step explanation:

3 degrees Celsius

It says at 4 p.m. was -2 degrees C. Then an hour later which would be 5 pm the temperature was 3 degrees C.

Answer:

well 5% of 600 is 30. so if you make 600 phone calls and an average of 5% of those calls are people signing up, then that would be 30.

Answer:

117

Step-by-step explanation:

Hi, If you were to add 75 to 42, you would get 117. Since a triangle's angles all have to add up to 180, the last angle would be 63. However, you are looking for the outside angle, which would then just be 117. Hope this is right!

Answer:

6

Step-by-step explanation:

6 is the slope of the function

Answer:

you make 20 dollars in a month

Step-by-step explanation:

15 is 3/4 a month, unit rate would be 5 dollars a week so therefore a whole month would be 20

Answer:

(2, 1)

Step-by-step explanation:

You add 5 to the x coordinate, which is -3 and you get 2. Then add -7 to the y coordinate, which is 8 and get 1

Answer:

(2, 1)

Step-by-step explanation:

(x + 5, y - 7), (-3, 8)

(- 3 + 5, 8 - 7) = (2 + 1)

Thus, The new point is (2 + 1).

Answer: 6, 21, 3

Step-by-step explanation:

2:7:1

Also, 2x 7x and 1x or just x

2x+7x+x = 30

10x = 30

x=3

So the three numbers: 2(3):7(3):1(3) OR 6:21:3

Answer:

The system that could be used find the price in dollars of each large candle, x, and each small candle, Y is given as:

5x + 7y = 96...... Equation 1

4x + 8y = 88..... Equation 2

Step-by-step explanation:

From the question:

Let cost of:

large candles = x

Small candles = y

A customer at a store paid $96 for 5 large candles and 7 small candles.

Hence:

5x + 7y = 96...... Equation 1

At the same store a second customer paid $8 less than the first customer for 4 large candles and 8 smal candies

Hence:

4x + 8y = $96 - $8

4x + 8y = 88..... Equation 2

The system that could be used find the price in dollars of each large candle, x, and each small candle, Y is given as:

5x + 7y = 96...... Equation 1

4x + 8y = 88..... Equation 2

Answer:

disproportionate stratified sample

Step-by-step explanation:

Based on the given information we can say that Abel's sample is a disproportionate stratified sample. This is the case mainly because the department worker population ranges from 40 to 120 workers. This changing population makes the 10 workers that were chosen for the sample not proportionate to the entire population. Therefore, under different population sizes workers have different chances of getting selected for the study which ultimately creates different results.

Answer:

-2

Step-by-step explanation:

To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]

     = [tex]\frac{-2-2}{-1+3}[/tex]

     = [tex]\frac{-4}{2}[/tex]

     = -2

D ......

Step-by-step explanation:

Given: Radius , r =21 cm

The angle at the center of the circle, n° =140°

Length of an arc =?

W.K.T Formula, Length of an arc = 2πr( n°÷360°) units

= 2*(22/7)*21*(140°/360°)

= 154/3

= 51.33cm

Answer:

2*(22/7)*21*(140°/360°)

= 154/3

= 51.33cm

Answer:A

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

Set of data in terms of ordered pairs represents a function when output value of each input value is different.

Option A

Since, for every value of x there is a different value of y, it's a function.

Option B

In each ordered pair, for every value of x there is a different value of y.

Therefore, it's a function.

Option C

From the given graph, for every value of x there is a different value of y.

Therefore, it's a function.

Option D

From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).

Therefore, the given set of ordered pairs doesn't represent a function.

Option D is the answer.

Complete Question

If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that:

A  

Both hypotheses H0 and H1 can be accepted

B

The null hypothesis H0 cannot be rejected

C

The null hypothesis H0 can be rejected

D

The research hypothesis H1 can be accepted

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

     The p-value  is  [tex]p-value = 0.07[/tex]

     The level of significance is  [tex]\alpha = 0.05[/tex]

Generally given that it is a one tail test then the possible value of  

   The null hypothesis is  [tex]H_o : \mu = x[/tex]

Here [tex]\mu[/tex] is the mean and  x  is the value  

 the possible values of the  alternative hypothesis is  [tex]\mu > x \ \ or \ \ \mu < x[/tex]

Now from the value given we see that the  [tex]p-value > \alpha[/tex]  hence

The decision rule is  

    Fail to reject  the null hypothesis
