Correct choice is D
Answer:
the giraffe gained 58 pounds each month.
Step-by-step explanation:
do 538-132 then do 406÷7. you will get 58.
hope this helps!
Given that
(2/x)+(3/y) = 13--------(1)
(5/x)-(4/y) = -2 -------(2)
Put 1/x = a and 1/y = b then
2a + 3b = 13 ----------(3)
On multiplying with 5 then
10a +15 b = 65 -------(4)
and
5a -4b= -2 ----------(5)
On multiplying with 2 then
10 a - 8b = -4 -------(6)
On Subtracting (6) from (4) then
10a + 15b = 65
10a - 8b = -4
(-)
_____________
0 + 23 b = 69
______________
⇛ 23b = 69
⇛ b = 69/23
⇛ b =3
On Substituting the value of b in (5)
5a -4b= -2
⇛ 5a -4(3) = -2
⇛ 5a -12 = -2
⇛ 5a = -2+12
⇛ 5a = 10
⇛ a = 10/5
⇛ a = 2
Now we have
a = 2
⇛1/x = 2
⇛ x = 1/2
and
b = 3
⇛1/y = 3
⇛ y = 1/3
<u>Answer :-</u>The solution for the given problem is (1/2,1/3)
<u>Check</u>: If x = 1/2 and y = 1/3 then
LHS = (2/x)+(3/y)
= 2/(1/2)+3/(1/3)
= (2×2)+(3×3)
= 4+9
= 13
= RHS
LHS=RHS is true
and
LHS=(5/x)-(4/y)
⇛ 5/(1/2)- 4/(1/3)
⇛(5×2)-(4×3)
⇛ 10-12
⇛ -2
⇛RHS
LHS = RHS is true
Answer:
<u>A. The probability that a Millennial is married is 0.089 or 8.9%.</u>
<u>B. The probability that a Baby Boomer is single, never married is 0.03 or 3%.</u>
<u>C. The probability that one person selected randomly (female or male) is married is 0.513 or 51.3% </u>
<u>D. The probability that someone who is living with a partner, but not married is a Generation X is 0.025 or 2.5%.</u>
Step-by-step explanation:
According to the information provided on the analysis table, we can answer the questions:
A. The probability that a Millennial is married is 0.089 or 8.9%.
B. The probability that a Baby Boomer is single, never married is 0.03 or 3%.
C. The probability that one person selected randomly (female or male) is married is 0.513 or 51.3% (Millennial 0.089 + Generation X 0.223 + Baby boomer 0.201)
D. The probability that someone who is living with a partner, but not married is a Generation X is 0.025 or 2.5%.
