Total votes for...

Wallace - 11
Casey - 8
Whitney - 8
Lisle - 8

with the overall total number of 35 votes. So from this data, it would appear that Whitney has a \dfrac8{35} probability of winning.

From a student body consisting of 420 voters, you would expect approximately 420\times\dfrac8{35}=96 votes to go to Whitney, and so the answer is D.

If the perimeter of A rectangle is 70" in and the length is 11" in more than its width find the area of the rectangle
steposvetlana [31]
First, write an equation system based on the problem
An equation for "the perimeter of a rectangle is 70 in" can be written as following
∴ 2l + 2w = 70  <em>(first equation)</em>
An equation for "the length is 11 in more than its width" can be written as following
∴ l = w + 11 <em>(second equation)</em>

Second, solve the equation by substitution method o find the dimension of the rectangle.
Substitute/plug l as (w+11) into the first equation
2l + 2w = 70
2(w + 11) + 2w = 70
2w + 22 + 2w = 70
4w + 22 = 70
4w = 70 - 22
4w = 48
w = 48/4
w = 12
The width of the rectangle is 12 in

Substitute w with 12 to the second equation
l = w + 11
l = 12 + 11
l = 23
The length of the rectangle is 23 in

Third, find the area of the rectangle
a = l × w
a = 23 × 12
a = 276
The area of the rectangle is 276 in²

write an equation in slope intercept form for the line that passes through the points (3,2) and(-9,6)
netineya [11]

Answer:

y = - \frac{1}{3} x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)

m = \frac{6-2}{-9-3} = \frac{4}{-12} = - \frac{1}{3}, hence

y = - \frac{1}{3} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 9, 6), then

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - \frac{1}{3} x + 3 ← in slope- intercept form
