Same idea here as last time.
You have a y-value, substitute it in the problem.
y=x+12
4x+2y=27
4x+2(x+12)=27
4x+2x+24=27
6x+24=27
-24 -24
6x=3
/6
x=.5

plug back in
y=(.5)+12
y=12.5

final answer:
x=.5,y=12.5

Answer:

x = 21

Step-by-step explanation:

We know that a triangle equals to 180 degrees.

Combine like terms. (x + 3x) and (-4 + 100)

x - 4 + 3x + 100 = 180

Subtract 96 on both sides.

4x + 96 = 180

-96 -96

Divide 4 on both sides.

4x = 84

--- -----

4 4

And you get a solution of 21.

x = 21

Check:

Substitute 21 into x.

Add/Subtract from left to right.

21 - 4 + 3(21) + 100 = 180

17 + 63 + 100 = 180

80 + 100 = 180

180 = 180

A fruit company has 20% returns in periods of normal rainfall and -3% returns in droughts. The probability of normal rainfall is

WARRIOR [948]

Answer:

$E(x) = 10.8\% \\\\$

The fruit company’s expected returns are 10.8%

Step-by-step explanation:

The expected returns of the fruit company is given by

$E(x) =\sum (x \cdot P(x)) \\\\$

For the given case,

Returns in normal rainfall = x₁ = 20% = 0.20

Returns in drought = x₂ = -3% = -0.03

Probability of normal rainfall = P(x₁) = 60% = 0.60

Probability of drought = P(x₂) = 40% = 0.40

So, the expected value of returns is

$E(x) = x_1 \cdot P(x_1) + x_2 \cdot P(x_2) \\\\E(x) = 0.20 \cdot 0.60 - 0.03 \cdot 0.40 \\\\E(x) = 0.12 - 0.012 \\\\E(x) = 0.108 \\\\E(x) = 10.8\% \\\\$

Therefore, the fruit company’s expected returns are 10.8%
