Answer:

(C). (Probability of state A*Value in state A)+(Probability of state B*Value in state B)

Step-by-step explanation:

The expected value of a probability distribution, E(X) is defined as:

$E(x)=\sum_{i=1} ^{k} x_{i} \cdot P(x_{i})\\$Where x=An Outcome\\P(x)=Probability of that Outcome$

Given Outcome A and B, the Expected Value therefore is:

Expected Value = (Probability of state A*Value in state A)+(Probability of state B*Value in state B)

Please help!!! What is the slope of a line that is perpendicular to this line?

Whitepunk [10]

$\frak{Hi!}$

$\orange\hspace{300pt}\above3$

If two lines are perpendicular to each other, their slopes

are negative inverses of each other.

Thus,

$\boldsymbol{\sf{Slope\:of\:this\:line=4}}}$

$\boldsymbol{\sf{Negative \ Inverse=-\displaystyle\frac{1}{4}}}$ . See how this works?

We took 4, then took its opposite, and flopped that over

$\orange\hspace{300pt}\above3$

Definition-:

Perpendicular lines are lines that intercept each other at a 90 deg. angle, which is usually called the right angle.

You use 4 gallons of water on 30 plants in your garden. At that rate, how much water will it take to water 45 plants

Gnesinka [82]

4 gallons of water ... 30 plants
x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

You should use the ratio so

2/ 4 = 6.5 / n

n= 6.5 x 4 / 2 = 13 inches

2- for two hours ------> four inches of snow
for x hours -----> y inches of snow
the equation is
2/4 = x/ y

x= 2y / 4
for x is the hours and y is the inches

5 gr granula ----------------------> 1750 calories
2 gr granula ----------------------> n ?? calories

by cross multiplication
n = 2 x1750 / 5 = 700 calories .

2-
she wants to eat 175 calories so
u put granula under granula and calories under calories to make this cross

5 gr granula ----------------------> 1750 calories
??? m granula ---------------------> 175 calories
by cross multiplication 
m = 175 x 5 / 1750 = 0.5 gr of granula
