P(X<=x) = 1 + 5.486 = 6.486
The z-score of the information given is,
z = (x - µ )/ σ
Where,
µ = mean
σ = standard deviation
From the information given,
x = 3.71
µ = 86
σ = √225 = 15
hence,
z = (3.71 - 86)/15 = -5.486
thus,
P(X<=x) = 1 + 5.486 = 6.486
hence , P(X<=x) = 1 + 5.486 = 6.486

No
We know scale factor(k)=y/x
Calculate units as 1 and find k
For left side
Hence its not a copy
Ok so <span>Interest = Principle * rate * time
P = 10,000
R = 3% = 0.03
T (we need to solve for t
I = 3600
now we sub..
3600 = (10,000)(0.03)(t)
3600 = 300t -- divide both sides by 300
3600/300 = t
12 = t
check..
I = prt
3600 = (10000)(0.03)(12)
3600 = (300)(12)
3600 = 3600 (correct)
It would take 12 years</span>

Answer:
x = 7 x = -6
Step-by-step explanation:
x^2−x−42=0
Factor
What two numbers multiply to -42 and add to -1
-7*6 = -42
-7+6 = -1
(x-7) (x+6) =0
Using the zero product property
x-7 =0 x+6 =0
x = 7 x = -6
