= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
Answer:
Probability that the respondent has a pet given that the respondent has had a pet is
or 0.46.
Step-by-step explanation:
We are given the following results below;
37% have a pet now and have had a pet.
63% do not have a pet now.
81% have had a pet.
19% do not have a pet now and have never had a pet.
Let event B = respondent has a pet now
Now, Probability that the respondent has had a pet = P(A) = 0.81
Probability that the respondent has a pet now and has had a pet =
= 0.37
So, Probability that the respondent has a pet given that the respondent has had a pet is given by = P(B/A)
<u>This conditional probability is solved as ;</u>
P(B/A) =
=
= 0.46.
Answer:

first create a bracket:

then solve the first bracket:

then open the remaining bracket:

carryout the subtraction operation:

Answer:
y=1/5x+12/5
Step-by-step explanation:
The slope is the same
When we substitute a specific valuefor each variable, and then perform the operations, it's called evaluating theexpression. Let's evaluate theexpression 3y + 2y when 5 = y. Click on the steps to see how it's done. Perform the operations, to find the value of the expression.
