A Mustang GT on Missouri has a marked price of $60,000. If paid in cash you are to pay 15% less than the marked price. It also have a hire purchase plan which states to pay 30% of the marked price and $1000 monthly payments for 4 yrs.
A) Discount on Cash price.
B) Cash Price.
C) Amount Payable.
D ) Hire Purchase Price
E ) Difference between the Hire Purchase price and the Cash Price.
Answer:
A) Discount on Cash price. ($9,000 )
B) Cash Price. ($51,000 )
C) Amount Payable. ($51,000 )
D ) Hire Purchase Price ($66,000 )
E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )
Step-by-step explanation:
The following is the workings:
The GT Missouri marked price = $60,000
If paying cash,
Discount = 15%
(15/ 100 ) x $60,000 = $9,000
Actual Price (less discount) = $60,000 - $9000 = $51,000
If hire purchase,
Firstly, 30% marked price,
= (30/100) x $60,000 = $18,000
Monthly payment = $1000
Period = 4 years = 4 x 12 = 48 months
Total monthly payment,
$1000 x 48 = $48, 000
Therefore, total hire purchase payment
Monthly payment + initial 30% payment
= $18,000 + $48,000 = $66,000
Difference between hire purchase and cash price,
= $66,000 - $51,000 = $15,000

A study that looked at beverage consumption used sample sizes that were much smaller than previous national surveys. One part of this study compared 20 children who were 7 to 10 years old with 5 who were 11 to 13. The younger children consumed an average of 8.2 oz of sweetened drinks per day while the older ones averaged 14.1 oz. The standard deviations were 10.8 oz and 8.2 oz respectively.
Required:
Do you think that it is reasonable to assume that these data are Normally distributed? Explain why or why not?
Answer:
Step-by-step explanation:
In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model. Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).
The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.
Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.
However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.
Hence, various measures like either goodness of fit or theory testing, would be used for this.

to do so
we need our algebra skills
substitute the value of r:
[tex] \displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2} [/tex]
recall law of exponent
[tex] \displaystyle \: ({x}^{m} {)}^{n} \iff \: {x}^{mn} [/tex]

Ahmed invests $4000 in two different accounts. The first account paid 10 %, the second account paid 9% in
interest. At the end of the first year he had earned $370 in interest. How much was in each account?
Answer: 3000$ in 9% account
Step-by-step explanation: sums in accounts are x and (4000-x)
Interests are 0.09x and 0.10(4000-x) = 400-0.1x
Now you get 0.09x -0.1x + 400 = 370
Then -0.01x = -30 and x= 3000

During a baskethall game, you want to pass the ball to either Player A or Player B. You estimate that Player B is about 15 feet from you, as shown. How far away from you is Player A?
Answer: 19.2 ft
Step-by-step explanation:
The distance between you, Player A and Player B are in the form of a right angled triangle so using the Pythagorean Rule, we can find the distance between you and Player A.
c² = a² + b²
c = hypotenuse = Distance between you and player A
a = Length of triangle
b = Height of triangle
c² = 12² + 15²
c² = 144 + 225
c = √369
c = 19.2 ft
The amount of time required to reach a customer service representative has a huge impact on customer satisfaction. Below is the Excel output from a study to see whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels. Assume that the population variances in the amount of time for the two hotels are not equal.
t-Test: Two-Sample Assuming Unequal Variances
Hotel 1 Hotel 2
Mean 2.214 2.0115
Variance 2.951657 3.57855
Observations 20 20
Hypothesized Mean Difference 0
df 38
t Stat 0.354386
P(T<=t) one-tail 0.362504
t Critical one-tail 1.685953
P(T<=t) two-tail 0.725009
t Critical two-tail 2.024394
A) State the null and alternative hypotheses for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
B) What is the value of the test statistic for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels? Explain how you obtain.
C) What is the critical value for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels at the 5% level of significance? Explain how you obtain.
D) Suppose α = 0.05. Which of the following represents the correct conclusion for a test on a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels?
1) There is no evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
2) There is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
3) There is no evidence that the variabilities of the amount of time required to reach a customer service representative between the two hotels are the same.
4) There is evidence that the variabilities of the amount of time required to reach a customer service representative between the two hotels are the same.
Answer:
A) H0: σ₁²-σ₂²= 0 against the claim Ha: σ₁²-σ₂²≠0
B) t= 0.3543860
C) t≥ t∝/2 ( d.f)=2.024394
D)1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.
Step-by-step explanation:
The claim is that there is evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels which is the
alternate hypothesis
The null hypothesis is the reverse of the alternate hypothesis
The null hypothesis is that there is not enough evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.
Part A) H0: σ₁²-σ₂²= 0 against the claim Ha: σ₁²-σ₂²≠0
Part B) t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)
t= 2.214- 2.0115/ sqrt ( 2.951657/20+ 3.57855/20)
t= 0.2025/ sqrt(0.14758285 + 0.1789275)
t= 0.2025/0.5714108
t= 0.3543860
Part C) for 2 tailed test the critical value of t is obtained by
t≥ t∝/2 ( d.f)= ± 2.024394
We look at the table with values 0.025 as ∝/2= 0.05/2= 0.025
in the degrees of freedom 38
The d.f = n1+n2-2= 20+20-2= 40-2= 38
Part D) Since the calculated value of t= 0.3543860 does not fall in the critical region t≥ t∝/2 ( d.f)= ± 2.024394 we conclude that H0 is true and accept the null hypothesis.
So option 1 is correct
1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Answer:
B. the mean is 59 inches
Step-by-step explanation:
if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.
Answer:
B: The mean wingspan is 59 inches.
Step-by-step explanation:
The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.
