Answer:
Area: pir^2
r=4
4pi^2
if pi=3.14
then the area is 50.24ft^2
Circumference: pi x d
d=8
8pi
if pi=3.14
then the circumference is 25.12ft.
Answer:
5(2x + 6) = -4(-5 -2x) + 3x
10x + 30 = 20 + 8x + 3x
10x + 30 = 20 + 11x
Applying the additive inverse property, we get,
10x + 30 - 10x - 20 = 20 + 11x - 10x - 20
10 = x
Answer:
The answer is the first one
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given:
Solving (a): P(x < 810)
To solve this, we make use of:
Because
So:
Hence:
Solving (b): P(x < 800)
To solve this, we make use of:
Because:
So:
Solving (c): P(x > 808.40)
Here, we make use of complement rule:
Where:
So:
Solving (d) The probability that the temperature lies outside 805.60 and 808.40
First, we calculate the probability that it lies within.
This is represented as:
This is calculated using:
Using complement rule, the required probability is:
