Answer:
10 more students chose purple than red as their favorite color
Step-by-step explanation:
Step 1
Determine the proportion of students that chose each color
purple=26%
red=22%
Step 2
Use the expression for the number of students per color as follows;
Number of students per color=proportion per color×total number of students
for purple;
proportion that chose purple=26%
total number of students=250
replacing;
Number of students that chose purple=(26/100)×250=65 students
for red;
proportion that chose red=22%
total number of students=250
replacing;
Number of students that chose purple=(22/100)×250=55 students
Step 3
Difference=65-55=10
10 more students chose purple than red as their favorite color
Answer:
The Answer is: 47 1/4
Step-by-step explanation:
11/8a + 5/4a = 18
Create a common denominator for he coefficient of a:
11/8a + 2/2 * 5/4a = 18
11/8a + 10/8a = 18
21/8a = 18
Multiply both sides by the inverse of 21/8:
8/21 * 21/8a = 18 * 21/8
a = 378/8 or 189/4 or 47 1/4
Answer:
1.) - 1/2
2.) the slope is 0 which means it is a vertical line
