Answer:
I think the nearest whole number for is 12.83333 is 13 because if we round it we got 13.
1st place has 10 possible people
2nd place has 9 possible people
3rd place has 8 possible people
10 × 9 × 8 = 720
or you could use permutation (order matters)
10P3 = 720
nPr
Answer:15
Step-by-step explanation:
In a square each side is the same length so you simply take 60 and divide it by 4 and you get 15.
Answer:
a) Expected amount of the gambler's win = $0.209
b) SD = 2.26
c)P (X >1) = P(z >0.35) = 0.36317
Step-by-step explanation:
The probability of winning, p = 12/38 =6/19
Probability of losing, q = 1 -p = 1-6/19
q = 13/19
Win amount = $5
Loss amount = $2
a) Expected total amount of win = ((6/19)*5) - ((13/19)*2)
Expected total amount of win = 1.579 - 1.369
Expected amount of win, E(X) = $0.209
b) Standard Deviation for the total amount of the gambler's win
E(X²) = (6/19)*5² - (13/19)*2²
E(X²) = 5.158
SD = 2.26
c) probability that, in total, the gambler wins at least $1.
P(X >1)
μ = E(x) = 0.209
z = (1-0.209)/2.26
z = 0.35
P( X >1) = P(z >0.35)
P(z >0.35) = 1 - P(z <0.35)
P(z >0.35) = 1 - 0.63683
P(z >0.35) = 0.36317
Answer:
- Width = x
- Length = 26 + 4x
<u>Perimeter</u>
<u />
<u>Therefore, the dimensions are</u>
- Width = x = 15
- Length = 26 + 4x = 26 + 4(15) = 86
