Answer:
No, because 3(2)+3 not equal to 15
Step-by-step explanation:
let the goals of Skylar be x
goals of wyatt be y
y=2x
x+y=15
3x=15
x=5
y=10
Possibility of red....13/26
possibility of black....13/26
these are simplified answers.....
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

Answer:
A) 60π cm³
Step-by-step explanation:
Given:
The<u> radius </u>of the base of a metallic rod is<u> 2 centimetres</u>, and its<u> height is 15 centimetres.</u>
Question asked:
What is the<u> volume </u>of this cylinder?
<u>Solution</u>:
As we know''
Therefore, the volume of this cylinder will be 
So slope=rise/run
rise=8
run=12
8/12=4/6=2/3
the slope=2/3
