100 POINTS AND BRAINLIEST A food truck did a daily survey of customers to find their food preferences. The data is partially entered in the frequency table. Complete the table to analyze the data and answer the questions:

Likes hamburgersDoes not like hamburgersTotal
Likes burritos49 92
Does not like burritos7538
Total 81205

Part A: What percentage of the survey respondents did not like either hamburgers or burritos? (2 points)

Part B: Create a relative frequency table and determine what percentage of students who like hamburgers also like burritos. (3 points)

Part C: Use the conditional relative frequencies to determine which data point has strongest association of its two factors. Use complete sentences to explain your answer. (5 points)

Answer from: amcalfie

PART A: 85.9% do not like either hamburgers or burritos

PART B: Frequency table is attached

PART C: There is a strong association between "like hamburgers" and "does not like burritos" because there are 81 respondents of the survey out of 110 (73%) that like hamburgers but not like burritos. On the other hand, there is also a strong association between "likes burritos" and "does not like hamburgers": 41 out of 70 respondents (59%) actually like burritos but don't like hamburgers. Therefore, most likely a person that like hamburgers does not like burritos and a person that likes burritos does not like hamburgers.

1. Let's complete the information in the frequency table:

Like Hamburgers ↓ Does Not Like Hamburgers↓ Total↓

Likes burritos → 29 41 70

Does not like burritos → 81 54 135

Total → 110 95 205

Part A. Like the question is either hamburgers OR burritos, we will sum 41 respondents that do not like hamburgers but like burritos, 81 that do not like burritos but like hamburgers and 54 that don't like neither hamburgers nor burritos.

This means our equation will look something like this:

41 + 81 + 54 = 176

Percentage = $\frac{175}{205}$ = 85.9% (rounding to the next tenth)

Part B: Create a relative frequency table and determine what percentage of students who like hamburgers also like burritos.

Like Hamburgers↓ Does Not Like Hamburgers↓ Total↓

Likes burritos → 14.1% 20% 34.1%

Does not like burritos → 39.5% 26.4% 65.9%

Total → 53.6% 46.4% 100%

To calculate this percentage we just take the number of respondents who like hamburgers and from that total we found that 29 also like burritos.

Percentage = $\frac{29}{205}$ = 14.1% (rounding to the next tenth)

Part C: There is a strong association between "like hamburgers" and "does not like burritos" because there are 81 respondents of the survey out of 110 (73%) that like hamburgers but not like burritos. On the other hand, there is also a strong association between "likes burritos" and "does not like hamburgers": 41 out of 70 respondents (59%) actually like burritos but don't like hamburgers. Therefore, most likely a person that like hamburgers does not like burritos and a person that likes burritos does not like hamburgers.

Answer from: Quest

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

$\newline{\text{the rate of change is change per unit time}}$ $\newline{\text{for (x,y), rate of change is }\frac{y_2-y_1}{x_2-x_1} \text{ or change in y divided by change in x}}$ $\newline{\text{for function 1, the cost goes up by 75-45=30 each time every hour}}$ $\newline{\text{that means that the slope of function 1 is 30 per hour}}$ $\newline{\text{for the 2nd function, 40 is added every hour. therefor, the slope is 40 per hour}}$ $\bigskip\newline{\text{since 40 per hour> 30 per hour, function 2 has a greater rate of change than function 1}}$ $\bigskip\newline{\text{the y intercept is the y value when x is 0}}$ $\newline{\text{for function 1, the y value when x is 0 is 45}}$ $\newline{\text{for function 2, the y value when x is 0 (or the flat rate) is 50}}$ $\newline{\text{since 50> 45, function 2 has a greater y intercept than funciton 1}}$ $\bigskip\bigskip\newline{\text{the answers are: }}$ $\newline{\text{ function 2 has a greater rate of change than function 1}}$ $\newline{\text{function 2 has a greater y-intercept than function 1.}}$
