A card is drawn from a well-shuffled deck of cards and then returned to the deck,
which is then shuffled again. A count of the number of times a card is selected
until an ace is drawn is best modeled by which distribution?
A:geometric
B:poisson
C:binomial
D:normal
A count of the number of times a card is selected until an ace is drawn is best modeled by Poisson distribution. Then the correct option is B.
What is Poisson distribution?A finite frequency distribution that estimates the likelihood that many independent occurrences will take place at the same moment.
A variable that plots symmetrically in the figure of a globe is the distribution of numerous unknown parameters.
A card is drawn from a well-shuffled deck of cards and then returned to the deck, which is then shuffled again.
A count of the number of times a card is selected until an ace is drawn is best modeled by Poisson distribution.
Then the correct option is B.

a person deposits rs 55000 in bank p for 2 years at the rate of 10% per annum compounded annually .but after one year , bank has changed the policy and decided to pay semi annual compounded interest at the same rate .what is the percentage difference between the compound interests of the first year and second year
Answer:
The interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.
Step-by-step explanation:
Given that a person deposits Rs 55000 in Bank P for 2 years at the rate of 10% per annum compounded annually, but after one year, bank has changed the policy and decided to pay semi annual compounded interest at the same rate, to determine what is the percentage difference between the compound interests of the first year and second year, the following calculation must be performed:
Year 1 =
55,000 x (1 + 0.1 / 1) ^ 1x1 = X
55,000 x 1.1 = X
60,500
Year 2 =
60,500 x (1 + 0.1 / 2) ^ 1x2 = X
60,500 x 1.05 ^ 2 = X
66,701.25 = X
55,000 = 100
60,500 = X
60,500 x 100 / 55,000 = X
110 = X
60,500 = 100
66,701.25 = X
66,701.25 x 100 / 60,500 = X
110.25 = X
Therefore, the interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.

You pay 5.65% on the first 110,000 of income and 1.45% in excess of $110,000. Calculate the FICA tax for an employee who earns 60,000 a year
Answer:
The FICA tax for an employee who earns 60,000 a year is $ 3,390.
Step-by-step explanation:
Given that you pay 5.65% on the first 110,000 of income and 1.45% in excess of $ 110,000, to calculate the FICA tax for an employee who earns 60,000 a year the following calculation must be performed:
60,000 <110,000
60,000 x 0.0565 = X
3,390 = X
Therefore, the FICA tax for an employee who earns 60,000 a year is $ 3,390.

The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rates of their athletes. At one large university, 91% of all students who started their studies in 2000-2010 graduated within 6 years. A sports reporter contacted 152 athletes randomly sampled from that same university and time period and found that 132 of them had graduated within 6 years.
(a) (5 points) Perform the appropriate hypothesis test to determine whether this is significant evidence that the percentage of athletes who graduate is less than for the student population at large, using the significance level a = 0.05. Remember for state the null and alternative hypotheses, the decision rule, and your conclusion.
(b) (3 points) Calculate the P-value for this test. Explain how this P-value can be use to test the hypotheses in part (a).
Answer:
a)
The null hypothesis is [tex]H_0: p = 0.91[/tex].
The alternate hypothesis is [tex]H_1: p < 0.91[/tex].
The decision rule is: accept the null hypothesis for [tex]z > -1.645[/tex], reject the null hypothesis for [tex]z < -1.645[/tex].
Since [tex]z = -1.79 < -1.645[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.
b)
The p-value for this test is 0.0367. Since this p-value is less than the significance level of [tex]\alpha = 0.05[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.
Step-by-step explanation:
Question a:
Perform the appropriate hypothesis test to determine whether this is significant evidence that the percentage of athletes who graduate is less than for the student population at large:
At the null hypothesis, we test if the proportion is the same as the student population, of 91%. Thus:
[tex]H_0: p = 0.91[/tex]
At the alternate hypothesis, we test that the proportion for athletes is less than 91%, that is:
[tex]H_1: p < 0.91[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Test if the proportion is less at the 0.05 level:
The critical value is z with a p-value of 0.05, that is, z = -1.645. Thus, the decision rule is: accept the null hypothesis for [tex]z > -1.645[/tex], reject the null hypothesis for [tex]z < -1.645[/tex].
0.91 is tested at the null hypothesis:
This means that [tex]\mu = 0.91, \sigma = \sqrt{0.91*0.09}[/tex]
A sports reporter contacted 152 athletes randomly sampled from that same university and time period and found that 132 of them had graduated within 6 years.
This means that [tex]n = 152, X = \frac{132}{152} = 0.8684[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.8684 - 0.91}{\frac{\sqrt{0.91*0.09}}{\sqrt{152}}}[/tex]
[tex]z = -1.79[/tex]
Since [tex]z = -1.79 < -1.645[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.
(b) (3 points) Calculate the P-value for this test. Explain how this P-value can be use to test the hypotheses in part (a).
The p-value of the test is the probability of finding a sample proportion of 0.8684 or below. This is the p-value of z = -1.79.
Looking a the z-table, z = -1.79 has a p-value of 0.0367.
The p-value for this test is 0.0367. Since this p-value is less than the significance level of [tex]\alpha = 0.05[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.

Subtract:
18x+21y from 22x-3y
Step-by-step explanation:
18x+21y
-
22x-3y
__________
= - 4x+24y
18x-(22x)=-4x
21y-(-3y)=24y // - * - = +
Jasmine decides to solve this system of equations using the substitution method.
3x + y = 18
4x + 2y = 10
These are the first two steps of the method that Jasmine will use.
Step 1: Solve for y in the first equation.
Step 2: Substitute the result from Step 1 into the second equation.
Which equation should be solved in Step 3 using Jasmine's method?
O A 4x + 18 + 3x = 10
B. 4x + 18 - 3x = 10
C. 4x + 36 - 3x = 10
D. 4x + 36 + 6x = 10
E 4x + 36 - 6x = 10
Answer:
Make x the same in both so
12x+ 4y=72
12x+6y=30
Now the 12x cancel eachother out so
Difference between 6y and 4y is 2y
Difference between 30 and 72 is -42
2y must equal -42
Y = -21
Substitute -21 into the equation
X = 13
