Answer:
The answer is A
Step-by-step explanation:
24/52 because there are 6 even number in a 13 card section
2,4,6,8,10,12
and there are four of them so you multiply 6 by 4 to get 24
since you know there are 52 cards then you will place 24 over 52
you can simplify this fraction to 6/13 depending what you want
Take 2,720/34,000=.0806. This means that 2,720 is 8.06% of the original number. In order to find the percentage of decrease, you take 100%-8.06%, which equals 91.94%. Your answer is 91.94%.
For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
Then, we can rewrite the expression as:
Answer:
Standard Deviation, σ: 1.5
Count, N: 10
Sum, Σx: 15
Mean, μ: 1.5
Variance, σ2: 2.25
Steps
σ2 =
Σ(xi - μ)2
N
=
(0 - 1.5)2 + ... + (5 - 1.5)2
10
=
22.5
10
= 2.25
σ = √2.25
= 1.5
