square root of 30. Hope this helps
Because the probability is uniform (equally likely) between 20 and 100 pounds, the probability distribution is uniform between 80 and 100 pounds, with the value 1/(100-20) = 1/80 chocolates/pound.
Let x = random variable that represents pounds of chocolate consumed.
Therefore
P(x < 60) = (60 - 20)*(1/80) = 1/2.
Answer: The probability is 1/2.
Answer:
452.16 m^2
Step-by-step explanation:
The surface area of a sphere is given by
A=4πr^2
= 4 * π * ( 6)^2
= 4 * π *36
144 π
Letting pi = 3.14
A is approximately 452.16 m^2
1/9 of total marbles = 1/9 × 36 = 4
so Alexis gave 4 marbles to Sara.
And so Alexis is left behind with 32 (36-4) marbles and so Sara have 4 marbles now
