So, the first number can be any of the 10 digits (0-9). From these 10 digits, 0,2,4,6, and 8 are even numbers. The total number of even numbers is 5. Therefore, 5 numbers are not even numbers.
So, the probability that a first character is an even number is equal to the number of even divided by the total number of possible outcomes. That is,
The probability is
0.50.
Answer:
E(Y) = $0.5
Var(Y) = 14.25
you should pay the same amount $0.5
Step-by-step explanation:
E(Y) = = Σ(YP)
P = probability of each outcomes.
Var(Y) = Σ
p − (μ x μ)
E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5
Var(Y) = (
x 0.25) + (
x 0.25) +(
x 0.5) - (
)
= 14.5 - 0.25
Var(Y) = 14.25
for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5
41 = x/84
x=84*41
x=3444
41 as a fraction of 84 is 3444/84
Step-by-step explanation:
increase in Tyler's pay = 16 - 14 = 2
% increase in Tyler's pay = 2/14 × 100 = 14.3%
Increase in Allies' pay = 18 - 16 = 2
% increase in Allies'pay = 2/16 × 100 = 12.5%
hence the right option is:
3).The percent increase Tyler's pay rate is greater than Allies'.
Increase in Martin's pay = 15.00 - 13.50 = 1.50
% increase in Martin's pay = 1.50/13.50 = 11.1%
Answer:
80
Step-by-step explanation:
Because it is more than 45 and the only one that is more that 45 is 80
