You suspect that the spiciness of food served in a restaurant is positively correlated with number of soft drinks ordered. What

would be your next steps to test your hypothesis?
A) Plot all data together on a dot plot to assess if there is any visible correlation between the data sets.
B) Observe several cases of people ordering food of varying spice-levels and number of soft drinks ordered.
C) Pick two points on the dot plot and find a line of best fit.
D) Find the correlation coefficient to see how well the line of best fit actually fits the data.

Answer:

B is correct.

Step-by-step explanation:

Positive correlation is a relationship between two entities, where they are dependent on each other.  If one entity decreases, the other also decreases, or when one entity increases the other also increases.

Here, we can say that option B is correct.

Observe several cases of people ordering food of varying spice-levels and number of soft drinks ordered. We can say if the food is very spicy people tend to drink something with it. So, this is absolutely true. As the level of spice increases, the number of soft drinks ordered also increases.

We can put all the given options in step by step procedure.

B) Observe several cases of people ordering food of varying spice-levels and number of soft drinks ordered.

A) Plot all data together on a dot plot to assess if there is any visible correlation between the data sets.

C) Pick two points on the dot plot and find a line of best fit.

D) Find the correlation coefficient to see how well the line of best fit actually fits the data.

Ymorist [56]

Answer:

x = \frac{3(3iy+9y-5+15i)}{10}

Andrea is at the grocery store buying fruit for a smoothie stand. She needs 7 boxes of raspberries for every 5 bunches of banana
Degger [83]

Answer:

The greatest number of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

Step-by-step explanation:

Let

x ---->the greatest number of boxes of raspberries that Andrea can buy

y ---->the greatest number of bunches of bananas that Andrea can buy

we know that

100\%+8\%=106\%=108/100=1.08 ---> sales tax

\frac{x}{y} =\frac{7}{5}

x=\frac{7}{5}y ----> equation A

1.08[2.50x+3.00y]\leq 135 ----> inequality B

substitute equation A in the inequality B

1.08[2.50(\frac{7}{5}y)+3.00y]\leq 135

solve for y

Multiply by 5 both sides to remove the fraction

18.9y+16.2y\leq 675

35.1y\leq 675

y\leq 19.23

so

The maximum value of y is 19

Find the value of x

replace the value of y in equation A until you get an integer value that satisfies the ratio 7:5  

For y=19

x=\frac{7}{5}(19)

x=26.6

For y=18

x=\frac{7}{5}(18)

x=25.2

For y=17

x=\frac{7}{5}(17)

x=23.8

For y=16

x=\frac{7}{5}(16)

x=22.4

For y=15

x=\frac{7}{5}(15)

x=21

therefore

The greatest number of of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

<u><em>Verify the inequality B</em></u>

1.08[2.50(21)+3.00(15)]\leq 135

1.08[52.5+45]\leq 135

105.3\leq 135 ----> is true
