Students in the seventh grade at Texas Intermediate School were surveyed to find out their favorite store. The graph below repre
sents the data from 80 students. How many more students surveyed chose Target as their favorite store over Ross? a.16 b.20 c.5 d.4
1 answer:
Answer:
(D) 4
Step-by-step explanation:
The graph which is a pie chart is produced and attached below.
There are a total of 80 Students.
From the graph, 25% choose Target and 20% choose Ross as their favorite store.
- 25% of 80 =0.25 x 80=20
- 20% of 80 =0.2 x 80=16
Number of Students who choose Target as their favorite store over Ross
=20-16
=4 Students.
<u>The correct option is D.</u>

The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26
Step-by-step explanation:
Given
The equation is in slope-intercept form, the coefficient of x will be the slope of given line. The slope is: 1/2
As the product of slopes of two perpendicular lines is -1.
Slope intercept form is:
Putting the value of slope
y=-2x+b
To find the value of b, putting (9,8) in the equation
Putting the values of b and m
Hence,
The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26
