Well given these 2 pieces of information, we can easily obtain the equation for the line which would be the following :

Y = 5x - 1.

The 4 points including the y intercept:

(0,-1)
(1,4)
(2,9)
(3,14).

You spin each spinner once. You get $50 if you spin a 2 and a vowel. You get $25 if you spin a 2 and a consonant. You get $5 if

The expected value of the game is $8.75.

----------------------

The expected value is the sum of each outcome multiplied by it's probability.
A probability is the number of desired outcomes divided by the number of total outcomes.

The probability of spinning a 2 and a vowel is: $\frac{1}{4} \times \frac{2}{8} = \frac{2}{32}$ .
Thus, $\frac{2}{32}$ probability of getting $50.

The probability of spinning 2 and a consonant is: $\frac{1}{4} \times \frac{6}{8} = \frac{6}{32}$

Thus, $\frac{6}{32}$ probability of getting $25.

The probability of spinning 1 and a vowel is: $\frac{3}{4} \times \frac{2}{8} = \frac{6}{32}$ .
Thus, $\frac{6}{32}$ probability of getting $5.

32 - (6 + 6 + 2) = 18, thus, $\frac{18}{32}$ probability of earning $0.

The expected value is:

$E = \frac{2}{32}(50) + \frac{6}{32}(25) + \frac{6}{32}(5) + \frac{18}{32}(0)$

$E = \frac{100 + 150 + 30}{32}$

$E = \frac{280}{32}$

$E = 8.75$

The expected value of this game is of $8.75.

Please help me find the answer

zheka24 [161]

The statement is always true because right angles measure 90 degrees and if you add them you get 180 and supplementary angles are angles that add up to 180.

Hope this helps :)

Answer: y=7x

Step-by-step explanation:

The way I did it was, I looked at the chart. The highest it goes is 30 and 210. So for your answer, you have to multiply. 7x30 gives you 210 and there y=7x

The ellipse 14x2+2x+y2=114x2+2x+y2=1 has its center at the point (b,c)(b,c) where

Nana76 [90]

18x^2 + 2x + y^2 = 1
==> 18(x^2 + x/9) + y^2 = 1 
==> 18(x^2 + x/9 + 1/324) + y^2 = 1 + 1/18 
==> 18(x + 1/18)^2 + y^2 = 19/18 
==> (x + 1/18)^2/19 + (y - 0)^2/(19/18) = 1. 

By comparing this to the standard form of an ellipse, the center is at (-1/18, 0).
