To find<span> the width, multiply the </span>length<span> that you have been given by 2, and subtract the result from the perimeter. You now have the total </span>length<span> for the remaining 2 </span>sides<span>. This number divided by 2 is the width.</span>
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
Which question in order for me 2 answer
We know the formula,
t =n =ar
n−1
Here n=8
Common ratio =−2 and first term =a=−6
t =8
=(−6)×(−2)
8−1
t =8
Use this formula
=(−6)×(−2)
7 t= 8
=768
