According to a survey conducted by an environmental organization, the probability that an eligible voter cares strongly about en

vironmental issues is 0.63, the probability that an eligible voter votes regularly is 0.51 and the probability that an eligible voter both votes regularly and care strongly about environmental issues is 0.30. If an eligible voter is selected at random what is the probability that the person cares strongly about environmental issues but does not vote regularly

Answer:

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.

Step-by-step explanation:

We have:

Probability that the voter cares for the environment P(E)=0.63

Probability that the voter votes regularly P(R)=0.51

Probability that the voter votes regularly and cares for the environment P(R,E)=0.30

We have to calculate the probability that the voter cares for the environment but does not vote regularly P(not R, E).

We know that the probability that the voter cares for the environment is 0.63, and is divided between the ones that vote regularly and the ones that don't:

P(E)=P(R,E)+P(not R,E)=0.63

We also know that the probability that the voter votes regularly and cares for the environment is P(R,E)=0.30. Then:

P(E)=0.30+P(not R,E)=0.63

P(not R,E)=0.63-0.30=0.33

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.

Stels [109]
\sqrt{5} \% \times 5\sqrt{5}=\frac{\sqrt{5}}{100} \times 5\sqrt{5}=\frac{5 \times \sqrt{25}}{100}=\frac{5 \times 5}{100}=\frac{25}{100}=0.25

The answer is B. 0.25.

Which table can be created using the equation below? –2 + 4x = y A 2-column table with 3 rows. Column 1 is labeled x with entrie
Pachacha [2.7K]

The correct answer is C. A 2-column table with 3 rows. Column 1 is labeled x with entries negative 5, 0, 3. Column 2 is labeled y with entries negative 18, negative 2, 10.

Explanation:

The purpose of an equation is to show the equivalence between two mathematical expressions. This implies in the equation "–2 + 4x = y" the value of y should always be the same that -2 + 4x. Additionally, if a table is created with different values of x and y the equivalence should always be true. This occurs only in the third option.

   x                 y

   5                -18    

   0                -2

   3                 10

First row:

-2 + 4 (5) = y  (5 is the value of x which is first multyply by 4)

-2 + 20 = -18 (value of y in the table)

Second row:

-2 + 4 (0) y

-2 + 0 = -2

Third row:

-2 + 4 (3) = y

-2 + 12 = 10

Solve the equation negative 3X +9 equals three(2x+3) + 3(x-4) + 1
timofeeve [1]

Answer:

1

Step-by-step explanation:

-3x+9=3(2x+3)+3(x-4)+1

Distributive property in the parenthesis

-3x+9=6x+9+3x-12+1

Combine Like Terms

-3x+9=9x-2

Get the x’s on one side

-3x+9=9x-2

+3.  +2    +3. +2

11=11x

Divide by 11 on both sides

11/11=1
