Answer: Missing detail ( weight of resistance = 6.69 Kg )
answer :
787.0785 watts 550.95 watts708.37 watts 550.95 watts 550.95 watts 472.25 wattsStep-by-step explanation:
Applying the equation for computing the power output
= Kg of resistance * number of revolutions * 11.765 ------- ( 1 )
Calculate the power output for each 5 second period
weight ( Kg of resistance ) = 6.69 Kg
Equation 1 becomes :
6.69 * number of revolutions * 11.765 ---- ( 2 )
Next :Apply equation (2) to every 5 seconds interval as represented in the table
For Time 0 - 5
Number of revolutions ( rpm ) = 10
power output = 6.69 * 10 * 11.765 = 787.0785 watts
cumulative rpm = 10 + 0
Cumulative Power = power output + previous power output = 787. 0785watt
For Time ( 5 - 10 )
Number of revolutions ( rpm ) = 7
Power output = 6.69 * 7 * 11.765 = 550.95 watts
Cumulative rpm = rpm + previous rpm = 7 + 10 = 17
Cumulative power = power output + previous power output
= 550.95 + 787.0785 = 1338.0285 watts
Power output for ( 10 - 15 ) = 6.69 * 9 * 11.765 = 708.37 watts
Power output for ( 15 - 20 ) = 6.69 * 7 * 11.765 = 550.95 watts
Power output for ( 20 - 25 ) = 6.69 * 7 * 11.765 = 550.95 watts
Power output for ( 25 - 30 ) = 6.69 * 6 * 11.765 = 472.25 watts

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%.
A study on how circus ticket pricing influences ticket sales shows that there is an average increase of 4 people for every $3 decrease on the price
of the ticket. A circus owner sells an average of 340 tickets when the price of a ticket is $75. If x represents the number of times the price
decreases by $3, which function describes the revenue earned by the circus owner terms of x?

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

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.
