The probability would be written as number of red marbles/ total number of marbles.
Probability of picking red would be 6/15.
Divide to get the percent: 6/15 = 0.4 = 40%
Answer:
158 m^2
Step-by-step explanation:
l = 5 m, w = 3 m, h = 8 m
S.A. = 
S.A. = 2{(5)(3) + (3)(8) + (5)(8)}
S.A. = 2(15 + 24 + 40)
S.A. = 2(79)
S.A. = 158 m^2
The dimensions would be 2 by 2.
We are fencing in 3 sides. The southern side is twice as expensive as the other two sides; the eastern and western sides together equal as much as the southern side. We have $80 to spend.
20x+10x+10x = 80
40x = 80
x = 2
This means that we can have 2 feet on all sides, for a total of 10(2)+10(2)+20(2)= 80.

Answer: 42 players are more than 73 inches tall
Step-by-step explanation:
Since the height of football players is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = height of football players.
µ = mean height
σ = standard deviation
n = number of sample
From the information given,
µ = 74 inches
σ = 1 inch
The probability that the height of a player is more than 73 inches tall is expressed as
P(x > 73) = 1 - P(x ≤ 73)
For x = 73
z = (73 - 74)/1 = - 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.16
P(x > 73) = 1 - 0.16 = 0.84
Therefore, the number of football players in the team whose height is more than 73 inches is
50 × 0.84 = 42
