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 hamburgers Does not like hamburgers Total
Likes burritos 29 41 70
Does not like burritos. 81 54 135
Total 110 95 205

AKA- 29 people like hamburgers and burritos, 41 people like burritos but not hamburgers, 70 people like burritos overall. 81 people like hamburgers but not burritos, and 54 people don't like hamburgers or burritos. 135 people don't like burritos. 110 people like hamburgers. 95 people do not like hamburgers. There are 205 people total.

Question: What is the marginal relative frequency of all customers that like hamburgers?

Part A || 16% of the people who took the survey claimed that they dislike both hamburgers and burritos

Part B || The marginal relative frequency of all of the customers that like hamburgers is 65%

Part C || According to the chart, those who liked hamburgers have the strongest association with 63 people who claimed to prefer the meal. I guess none of these people are vegetarian.

Hope this helps :)

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
