Answer:
Area ≈ 4,500
Step-by-step explanation:
Radius of Circle A
r = √
r = √
r ≈ 12.62
Diameter of Cricle A
d = 2r
d = 2(12.62)
d = 25.24
25.25 x 3 =75.72 --> This is the diameter of Circle B
Radius of Circle B
r =
r =
r = 37.86
Area of Circle B
A =
A = (37.86)²
A = 4,503.09
Answer:
a. -1.35
b. 0.177016
Step-by-step explanation:
According to the question, following data is given
Brown eyes american percentage is 45
Random sample be 80 out of which 30 had brown eyes
Based on the above information
The computation is shown below:
a. The proportion of the sample is
The z value is
= -1.35
b Now the P value is
As z comes -1.35
So, there is a two tailed p value i.e. 0.177016
Answer:
The probability that a randomly selected survey participant didn't got the flew = 0.75
Step-by-step explanation:
Students got the flu during Winter 2013 = 12 %
Students got the flu during Winter 2014 = 18 %
Students got the flu during both years = 5 %
Students got the flu at least in one year = 12 + 18 - 5 = 25 %
Students didn't got the flew = 100 - 25 = 75 %
⇒ The probability that a randomly selected survey participant didn't got the flew =
⇒ 0.75
This is the probability that a randomly selected survey participant didn't got the flew.
4(6x + 11)
Distributive property
4*6x = 24x
4*11 = 44
Answer: 24x + 44
