Answer: 0.4 which is choice C

====================================

Work Shown

Focus on the "riverside high school" row only

A = number of twelfth graders = 200

B = number of students = 500

P = probability of picking a twelfth grader

P = A/B

P = 200/500

P = 2/5

P = 0.4

Because there are 500 people total in the school and there are only 200 students in 12th grade, divide 200 by 500 and then you get 0.4

The polygons are similar but not necessarily drawn to scale find the value of x x -3 8 16 2.5 to 4
Dmitriy789 [7]
You have to multiply the smaller one by a common number to make them equal. If you multiply it by 4;

4x4=16
2x4=8
2.5x4=10

So, plugin to get, x-3=10.

x=13.

20 POINTS PLEASE ANSWER ASAP What is the equation for the line? Enter your answer in the box.
pogonyaev

Answer: y= -2x - 4

Step-by-step explanation:

This is a straight line, so it can be expressed by y = mx + c.

Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.

So, c = -4.

m is slope.

Use slope formula to find m.

m = ( -4 - 0 ) / ( 0 -(-2))

m = -4 / 2

m = -2

Now put values into this equation

y = mx + c

y = -2x - 4

Add (7х2 – 3x) + (5х – 6).
Masja [62]

Option C: The solution is 7x^{2} +2x-6

Explanation:

The given expression is (7x^{2} -3x)+(5x-6)

We need to solution of the given expression.

The solution of the given expression can be determined by adding the two expressions.

Let us remove the parenthesis.

Thus, we have,

7x^{2} -3x+5x-6

Adding the like terms, we have,

7x^{2} +2x-6

Thus, the solution is 7x^{2} +2x-6

Hence, Option C is the correct answer.
