Several students were surveyed about their favorite class. The results are art 26, English 19, math 21 music 16 and science 32.

SOVA2 [1]

Art class / all classes = 16 / (26 + 19 + 21 + 16 + 32) = 16/114 = 8/57

Answer:

The ratio of candidate 2's votes to candidate 1's votes was 24:8

The ratio of candidate 1's votes to candidate 2's votes was 1:3

Step-by-step explanation:

Candidate 1's votes is 8000

Candidate 2's votes 24000

To get the ratio of candidate 2's votes to candidate 1's votes take 24000 : 8000 divide by 1000 both sides you get 24:8

To get the ratio of candidate 1's votes to candidate 2's votes take 8000 : 24000 divide 8000 both sides you get 1:3

Other ratios whatever you divide the answers is incorrect

Write an equation in slope-intercept form that goes through (12, 4) and (20,8).

spayn [35]

Answer:

Equation in slope-intercept form that goes through (12, 4) and (20,8) is: $y = \frac{1}{2}x-2$

Step-by-step explanation:

Given two points are:

$(x_1,y_1) = (12,4)\\(x_2,y_2) = (20,8)$

Slope intercept form of line is given as:

$y = mx+b$

Here m is the slope of the line and b is the y-intercept.

Slope of a line is calculated by the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{8-4}{20-12}\\m = \frac{4}{8}\\m=\frac{1}{2}$

Putting the value of slope in slope-intercept form we get

$y = \frac{1}{2}x+b$

To find the value of b, any one point will be put in the equation

Putting the first point (12,4) in the equation

$4 = \frac{1}{2}(12) + b\\4 = 6+b\\b = 4-6\\b = -2$

Putting the value of b

$y = \frac{1}{2}x-2$

Hence,

Equation in slope-intercept form that goes through (12, 4) and (20,8) is: $y = \frac{1}{2}x-2$
