Ms. Gonzales gathered data on the number of vowels in the first and last names of each of her students. The data are shown in the dot plot. Vowels in student names. Number of vowels.

What percentage of the students have 5 or more vowels in their first and last names?

From the dot plot, we have that 90.91% of the students have 5 or more vowels in their first and last  names.

The dot plot states that:

2 students have 4 vowels in their first and last name.

3 students have 5 vowels.

8 students have 6 vowels.

9 students have 7 vowels.

Then:

Total of 2 + 3 + 8 + 9 = 22 students.

3 + 8 + 9 = 20 have or more vowels.

90.91% of the students have 5 or more vowels in their first and last  names.

b

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.
