Answer:
solution given;
half way between 0 and 121=?
let a=0
and
b=121

Answer:
<u>Gina's height in inches</u><u>:</u> 63 inches
<u>Noelle's height in inches</u><u>:</u> 67 inches
<u>Equation</u><u>:</u> n + (n - 4) = 130
Step-by-step explanation:
n + (n - 4) = 130
n + n - 4 = 130
2n - 4 = 130
2n - 4 + 4 = 130 + 4
2n = 134
2n ÷ 2 = 134 ÷ 2
n = 67
67 - 4 = 63
Answer:
Money with Mary = $28
Money with Vivan = $12
Step-by-step explanation
Money with Mary = $ m
Money with Vivan = $v
If mary gave vivan $8 they would have same amount. $ 8 is reduced from Mary's amount 'm' and $8 is added to vivan amount 'v'
m - 8 = v + 8
m = v + 8 +8
m -v = 16 ----------------(I)
If vivan gives mary $8, then mary would have 9 times as much as vivan.
9(v - 8) = m + 8
9v - 72 = m + 8
9v - m = 8 + 72
-m + 9v = 80 --------------(II)
Add equation (I) and (II). Thus m will be cancelled and we will get the value of v
(I) m - v = 16
(II) <u>-m + 9v = 80</u> {Now add}
8v = 96
v = 96/8
v = $ 12
Plugin v = 12 in equation (I)
m - 12 = 16
m = 16 +12
m =$ 28
Answer:
52% probability that a randomly selected puppy in the shelter will get adopted and live 7 or more years
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: A puppy is adopted.
Event B: The puppy lives 7 or more years.
An animal shelter has a 65% adoption rate for puppies
This means that 
Of the puppies who are adopted, 80% live to be 7 years or older.
This means that 
What is the probability that a randomly selected puppy in the shelter will get adopted and live 7 or more years
52% probability that a randomly selected puppy in the shelter will get adopted and live 7 or more years
Answer: x = -6
Step-by-step explanation:
Whenever you want to find the x-intercept (this would also apply to y-intercept, but we're focusing on x), you'd simply equal y to 0 and then solve for x.
-2x + 3(0) = 12
-2x = 12
÷-2 ÷-2
The answer is going to be x = -6
