You place a 1-dollar bet on the number 17 at Las Vegas, and your friend places a 1-dollar bet on black (see Exercises 1.1.6 and 1.1.7). Let X be your winnings and Y be her winnings. Compare E(X), E(Y ), and V(X), V(Y). What do these computations tell you about the nature of your winnings if you and your friend make a sequence of bets, with you betting each time on a number and your friend betting on a color
Answers
Answer:
E(x) = -$0.05263
E(y) = -$0.05263
V(x) = 0.9972
V(y) = 32.23
the expectations are the same, both will lose the same amount of money if they play for 38 times.
Though Variance is different. The girl betting on colors has little chance to gain and lose but the boy betting on number has huge deviation
Step-by-step explanation:
Given that; you place a 1-dollar bet on the number 17 at Las Vegas and your friend places a 1-dollar bet on black.
Let x represent your winnings and y represent your friends winnings
we know that, There are 18 black slots, 18 red slots and two green slots (0 and 00) on a US roulette wheel.
so, the chances of getting black(red) = 18/38
now, E(y) = (18/38)$1 + (20/38)(-$1)
E(y) = -$0.05263
Now, bets made on the chart of the various numbers 1 to 36 and zero, Just put a chip down in the middle of the square with the number you select. If it comes up, it pays 35-to-1. It is called a straight up bet.
hence, the chance of getting selected number will be 1/38
so E(x) will be;
E(x) = (1/38)$35 + (37/38)(-$1)
E(x) = -$0.05263
So, V(x) will be;
V(x) = [ 1 - (1/19)² ]
= 1 - 0.00277
V(x) = 0.9972
V(y) = { [ (35)² × (1/38) ] - (1/19)² }
= 32.2368 - 0.00277
V(y) = 32.23
Therefore, the expectations are the same, both will lose the same amount of money if they play for 38 times.
Though Variance is different. The girl betting on colors has little chance to gain and lose but the boy betting on number has huge deviation.
Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 66 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 62 miles per hour and 70 miles per hour. (assume the data set has a bell-shaped distribution.)
Answer: 99.7
Answers
Answer:
The percentage of that vehicles whose speeds are between 62 miles per hour and 70 miles per hour
P(62≤X≤70) = 68.76
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 66miles per hour
Given that the standard deviation of the Population = 4 miles per hour
Let 'X' be the random variable in normal distribution
Let x= 62
[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{62-66}{4} =-1[/tex]
let x=70
[tex]Z = \frac{70-66 }{4} = \frac{70-66}{4} =1[/tex]
Step(ii):-
The probability that vehicles whose speeds are between 62 miles per hour and 70 miles per hour
P(62≤X≤70) = P(-1≤Z≤1)
= P(z≤1) -P(Z≤-1)
= P(Z≤1)+P(Z≤1)
= 2×P(Z≤1)
= 2×0.3438
= 0.6876
The percentage of that vehicles whose speeds are between 62 miles per hour and 70 miles per hour
P(62≤X≤70) = 68.76

The average smoker typically pays 15% higher life insurance costs than the average non-smoker. If the monthly cost to a non-smoker is $500 dollars per month, how much would the average smoker pay per month for the same life insurance policy?
a) $500.15
b) $515.00
c) $533.00
d) $575.00
Answers
Answer:
$75
Step-by-step explanation:
The average smoker pay 15% life insurance than the non-smoker
The monthly cost of a non-smoker is $500 per month
Therefore the amount that would be paid by the average smoker in a month can be calculated as follows
= 500 × 15/100
= 500 × 0.15
= 75
Hence the amount to be paid is $75
Rachel is purchasing a condominium and is financing $485,000 with a 30-year 6/1 ARM at 4.95% with a 1/10 cap structure. What will her payments be at the beginning of year 7?
Answers
Answer: Rachel's payment will be $2,588.78
Step-by-step explanation:
Given that;
Loan amount L = $485,000
number of months n = 30 × 12 = 360
Interest rate per month C = 4.95 / (100 × 12) = 4.95/1200 = 0.004125
Now, using the formula
P = L[ c ( 1 + c )ⁿ / ( 1 + c )ⁿ - 1 )
we substitute
P = 485,000 × [ 0.004125 ( 1 + 0.004125 )³⁶⁰ / ( 1 + 0.004125 )³⁶⁰ - 1 )]
P = 485,000 × [ 0.01815619 / 3.4015 ]
P = 485,000 × 0.0053377
p = 2,588.78
Therefore, Rachel's payment will be $2,588.78

Consider the expressions (3m+2n−6) and (−4−6m+7n).
Part A
What is the sum of the expressions for n=−2 and m=5?
The sum is
Answers
Answer:
5, -20
Step-by-step explanation:
Given the equation (3m+2n−6) and (−4−6m+7n).
Also, given that we're told that
n = -2 and
m = 5, if we take a rather direct approach by substituting like for like, we have
(3m+2n−6) = (3 * 5 + 2 * -2 - 6)
(3m+2n−6) = 15 - 4 - 6
(3m+2n−6) = 15 - 10
(3m+2n−6) = 5
(−4−6m+7n) = (-4 - 6 * 5 + 7 * 2)
(−4−6m+7n) = -4 - 30 + 14
(−4−6m+7n) = -34 + 14
(−4−6m+7n) = -20
Therefore, we proceed to conclude that the answers are 5 and -20 respectively
