Answer:
00000
Step-by-step explanation:
I think you have a problem with your equation. You can't have 2 equal signs. I would say 1200 is your slope though. I simply subtracted 20x from 1220x <span />
With simple interest, you only earn 5.5% of the original $150 each year.
So after 4 years, your money will earn (5.5% x 4) = 22% of the original $150 .
22% of $150
= 0.22 x $150
= $33 .
Answer:
-2
Step-by-step explanation:
rise/run
But in this case, since you start by doing down, it would be negative.
Answer:
0.85083 ; 0.83147 ; 0.6823 ; 0.015386
Step-by-step explanation:
Given that:
σ = 25
μ = 86
(a) x is more than 60
P(x > 60)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (60 - 86) /25
Z = - 1.04
P(Z > - 1.04) = 0.85083 (Z probability calculator)
(b) x is less than 110
P(x < 110)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (110 - 86) /25
Z = 0.96
P(Z < 0.96) = 0.83147 (Z probability calculator)
(c) x is between 60 and 110
P(x < 110) - P(x < 60)
P(Z < 0.96) - P(Z < - 1.04)
0.83147 - 0.14917
= 0.6823
(d) x is greater than 140
P(x > 140)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (140 - 86) /25
Z = 2.16
P(Z > 2.16) = 0.015386 (Z probability calculator)
