Mr. Bryant is trying to figure out which class project to work on for community service. He surveyed the junior and senior students about their preferred project. The frequency table shows the responses of the students.

The joint frequency of being a senior and wanting to have a park cleanup. is 26/200 or 13%.

Correct statement and question:

Mr. Bryant is trying to figure out which class project to work on for community service. He surveyed the junior and senior students about their preferred project. The frequency table shows the responses of the students.

                      Juniors Seniors Total

Park cleanup    30      26        56

Food kitchen     50      34        84

Clothing drive   10       50        60

Total                   90      110       200

Determine the joint frequency of being a senior and wanting to have a park cleanup. Explain what this answer represents.

Step-by-step explanation:

Let's recall that joint frequency is the number of times a combination of two conditions happens together. In the question, we're asked about the frequency that a student surveyed is a senior and wants to work in a park cleanup as a community service.

Thus, the joint frequency of being a senior and wanting to have a park cleanup. is 26 out of 200 surveyed students. We can write it as 26/200 or 13%.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
