Answers
Answer:
A. Compound Interest
Step-by-step explanation:
Compound interest is interest paid on both the principal and previously earned interest.
Compound interest earned on both the principal and any previously earned interest. Therefore, the correct answer is option A.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex]
Therefore, option A is the correct answer.

Step-by-step explanation:
To find the total price we need to find 4.75% of the 20 and to do that we need to multply 20 with 4.75 and divide it by 100
20 × 4.75 ÷ 100 = 0.95

An initial investment of $2,000 earns 7% interest compounded continuously. What will the investment be worth in 17 years? (Round your answer to the nearest cent.)
Answers
Answer:
Future value, A = $6,317.6
Step-by-step explanation:
Given the following data;
Principal = $2,000
Interest rate = 7%
Time = 17 years
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 2000*(1 + \frac{7}{100})^{17}[/tex]
[tex] A = 2000*(1 + 0.07)^{17}[/tex]
[tex] A = 2000*(1.07)^{17}[/tex]
[tex] A = 2000 * 3.1588 [/tex]
Future value, A = $6,317.6

1 a)8 miles per hour 1 b) 1 hour and 90 minutes 2 a) 24 hours and 6minutes 2 b) 3hours 3 a) 260 hours and 45 minutes 3 b) 40 minutes
Step-by-step explanation:
I don't know for sure if this is all correct but at least you'll have something to write down
Answer:
1a. 8 miles per hour
1b. 32 km per hour
2a. 28 miles
2b. 3 hours
3a. 2925
3b. 1/4 hour or 15 minutes
Step-by-step explanation:
For number 1a, think of 2 1/2 hours equals 20 miles as 2 1/2x=20. The x being hours, and the 20 being 20 miles. You want the equation to become x=?. So you divide 2 1/2x=20 by 2 1/2 to make the equation start with x=. You end up with x=8. Or you could just think of it as divide 20 miles by 2 1/2 hours. Either way, you end up with 8 miles per hour. For number 1b, you do the same thing as before, but you have to make 4 hours and 45 minutes a fraction. So, the are 60 minutes in an hour, so the fraction would be 45/60. Then you simplify that down to 3/4. So, 152 km divided by 4 3/4 is 32 km per hour.
For number 2a, set aside 30 minutes for now. She can go 24 miles in 3 hours. Because 8 miles times 3 hours equals 24 miles. It’s like instrad of 8 miles per hour, it’s 24 miles per 3 hours. Then, because 30 minutes is half of an hour, 8 divided by 2 would make it 4 miles per half an hour. So 24 plus 4 is 28 miles. For number 2b, you want to know how many hours it took to travel 1980 miles. Since you already knowmthat is takes one hour to go 660 miles, pretend that each 660 miles is one hour. So you divide 1980 by 660 so see how many one hours fit. You get 3. So, an airplane can fly 1980 miles in 3 hours.
For number 3a, like 2a, you basically multiply the constant speed by the full hours then the fraction, and add them together. You could also just multiply the constant speed by the number 3 3/4. That way you get the miles per 3 3/4 hours. 3 3/4 times 780 is 2925. So the plane can fly 2925. For number 3b, to get the 2 miles per ? hours, you have to divde 8 by 4 to get to 2. So you divide 1 hour by 4 to get the answer. So it’s 1/4, (one fourth of an hour) or 15 minutes 1/4 of 60 (the amount of minutes in an hour) for Mary to go 2 miles.

A. 177.8 cm
B. 64.3 cm
C. 50.3 cm
D. 51.1 cm
E. 41.1 cm
Answers
Answer:
Option D. 51.1 cm
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, c is the distance between the tip of the cone and its rim.
The value of c can be obtained as follow:
Angle θ = 38.5°
Adjacent = WY = 40 cm
Hypothenus = WZ = c =?
Cos θ = Adjacent / Hypothenus
Cos 38.5 = 40 / c
0.7826 = 40 / c
Cross multiply
0.7826 × c = 40
Divide both side by 0.7826
c = 40 / 0.7826
c = 51.1 cm
Thus, the distance between the tip of the cone and its rim is 51.1 cm.

Option D. 51.1 centimeters

Do mice show a preference for using one paw over the other? Attempting to answer this question, a researcher tested a random sample of 48 mice and observed which forepaw (right or left) the mice used to retrieve food from a narrow tube. Eighteen of the mice used their right paw, while the rest used their left paw.
Does this data suggest that mice show a preference towards one paw over the other? Carry out the appropriate test and include all steps for full credit.
During the course of the experiment, the researcher noticed that individual mice sometimes switched which forepaw they used to retrieve the food. So she repeated this study on the same 48 mice, but measured each one 10 times and she recorded which forepaw was used each time. With her new dataset of 480 observations, would you be able to run the same analysis as in part (a)? If so, carry out the analysis and compare the results. If not, why not?
Answers
Answer:
It all depends on the food they are going for, just like humans, mice have instincts. For example, if you were falling forward, which foot would you put out? Most likely the opposite one. I hope this helps you!
Step-by-step explanation:
Using hypotheses testing,
In both cases, we fail to reject the null hypothesis, indicating that there is not enough evidence to suggest that mice show a preference towards one paw over the other.
We have,
(a)
To test whether the data suggest that mice show a preference towards one paw over the other, we can use a one-sample proportion test.
The null hypothesis (H0) is that the proportion of mice that use their right paw is 0.5 (indicating no preference towards one paw over the other).
The alternative hypothesis (Ha) is that the proportion of mice that use their right paw is different from 0.5 (indicating a preference towards one paw over the other).
We can use a significance level (alpha) of 0.05.
To conduct the test, we can calculate the test statistic using the formula:
z = (p - 0.5) / √(0.5 x 0.5 / n)
where p is the proportion of mice that use their right paw, and n is the sample size.
Using the given data, we have:
p = 18/48 = 0.375
n = 48
Plugging in the values, we get:
z = (0.375 - 0.5) / √(0.5 x 0.5 / 48) = -1.714
Using a standard normal distribution table or calculator,
We can find the p-value associated with this test statistic.
The p-value is the probability of observing a test statistic as extreme as -1.714 or more extreme, assuming the null hypothesis is true.
The p-value for this test is 0.0869.
Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis.
This means that we do not have sufficient evidence to conclude that mice show a preference towards one paw over the other, based on the given sample.
(b)
With the new dataset of 480 observations, we can still conduct a similar analysis using a one-sample proportion test.
However, since each mouse was measured 10 times, the observations are no longer independent.
Therefore, we need to use a different test that accounts for the dependency between observations, such as McNemar's test.
McNemar's test is a test of the marginal homogeneity of a two-way table, where the same subjects are measured twice on a binary outcome.
In this case, we can create a 2x2 contingency table of the number of times each mouse used their right or left paw, and conduct a McNemar's test on this table.
The null hypothesis for McNemar's test is that there is no difference in the proportions of mice that use their right or left paws.
The alternative hypothesis is that there is a difference.
To conduct the test, we can calculate the test statistic using the formula:
chi-squared = (|b-c|-1)² / (b+c)
where b is the number of mice that used their right paw more often, and c is the number of mice that used their left paw more often.
Using the given data, we have:
b = 214
c = 244
Plugging in the values, we get:
chi-squared = (|214-244|-1)² / (214 + 244) = 2.417
Using a chi-squared distribution table or calculator with 1 degree of freedom (since we have a 2x2 table), we can find the p-value associated with this test statistic.
The p-value is the probability of observing a test statistic as extreme as 2.417 or more extreme, assuming the null hypothesis is true.
The p-value for this test is 0.119.
Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis.
This means that we do not have sufficient evidence to conclude that there is a difference in the proportions of mice that use their right or left paws, based on the new dataset.
Thus,
In both cases, we fail to reject the null hypothesis, indicating that there is not enough evidence to suggest that mice show a preference towards one paw over the other.
