To find the y-intercept of the equation, we will put 0 in for x, and find y.
So, y = 14.2 - 3.9(0)
y = 14.2
Answer:
240
Step-by-step explanation:
So 60/100 x (n) = 144
We should be able to multiple both sides by 100, and divide each side by 60 to get our answer.
n = 144 x (100/60) which then equals 240.
Answer:number of children negative for chicken pox=28
Step-by-step explanation:
Number of children positive for chicken pox =18 out of 30
Therefore number of children negative for chicken pox is 12 out of 30 ie ( 30-18)
Such that the ratio of positive tested chicken pox children to negative tested chicken pox children =18:12
Therefore total ratio =18 +12=30
Suppose there are 70 children,then number of children negative for chicken pox =
12/30 x 70 =28
Answer: y=3
Step-by-step explanation: 6(4.5y−12)=9
Step 1: Simplify both sides of the equation.
6(4.5y−12)=9
(6)(4.5y)+(6)(−12)=9(Distribute)
27y+−72=9
27y−72=9
Step 2: Add 72 to both sides.
27y−72+72=9+72
27y=81
Step 3: Divide both sides by 27.
27y/27 =81/27
Answer:
option B
Step-by-step explanation:
given,
3-month T-bill currently yields = 3%
customer price have been rising = 2% rate
Ai Lun's estimate of the real rate = ?
real rate return
= 
= 
= 
= 
= 0.0098
= 0.98 % ≅ 1 %
hence, the correct answer is option B
