(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439
Answer:
50.24
Step-by-step explanation:
You will do
(area of a circle) x (hight)
Area of a circle = A
lets say 3.14 is pi
A = 3.14 x 2^2
A = 3.14 x 4
A = 12.56
Now
V = 12.56 x 4
V = 50.24

Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205
10 = Ten
100 = One Hundred
1,000 = One Thousand
------------
10 = 10^1
100 = 10^2 = 10 x 10
1,000 = 10^3 = 10 x 10 x 10
