Answer:

$103968.11.

Step-by-step explanation:

Given information:

Principal amount = $240,000

Rate of interest = 1.2% = 0.012

Number of years = 30

Number of times in an year = 24

Formula for amount:

[tex]A=P(1+\dfrac{r}{n})^{nt}[/tex]

where,

P is principal, r is rate of interest, t is number of years, n is number of times interest compounded in a year.

[tex]A=240000(1+\dfrac{0.012}{24})^{24(30)}[/tex]

[tex]A=240000(1.0005)^{720}[/tex]

[tex]A=343968.11[/tex]

Now,

[tex]Interest=A-P[/tex]

[tex]Interest=343968.11-240000[/tex]

[tex]Interest=103968.11[/tex]

Hence, the interest is $103968.11.

Final answer:

The total interest paid on a $240,000 loan with a 1.2% interest rate compounded bimonthly over 30 years is $103,875.4

Explanation:

Calculating Compound Interest Over 30 Years

Mr. and Mrs. Rainer took out a $240,000 loan for their home with an interest rate of 1.2% compounded bimonthly. To calculate the total amount of interest they will pay after 30 years, we need to use the formula for compound interest:

A = [tex]P(1 + \frac{r}{n})^{nt[/tex]

Where:

A = the future value of the investment/loan, including interest

P = the principal investment amount ($240,000)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

First, convert the interest rate from a percentage to a decimal by dividing by 100:

r = 1.2% / 100 = 0.012

Since the interest is compounded bimonthly, it is compounded 6 times a year (n = 6). The loan is for 30 years (t = 30).

Now, we can substitute the values into the formula and calculate A:

A = [tex]$240,000(1 + \frac{0.012}{6})^{6*30[/tex]

A = 240,000 * 1.002¹⁸⁰

A = 343,875.4

We'll subtract the principal (P) from A to find the total amount of interest paid over the 30 years.

I = A - P

I = 343,875.4 - 240,000

I = 103,875.4

Answer: 8.9*10^(-6)

Answer:

[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]  

[tex]p_v =P(z<-3.137)=0.0009[/tex]  

Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%

Step-by-step explanation:

Data given

n=6997 represent the random sample taken

X=1296 represent the returned surveys

[tex]\hat p=\frac{1296}{6997}=0.185[/tex] estimated proportion of  returned surveys

[tex]p_o=0.2[/tex] is the value that we want to test

z would represent the statistic (variable of interest)

[tex]p_v[/tex] represent the p value (variable of interest)  

System of hypothesis

We need to conduct a hypothesis in order to test the claim that the true proportion of returned surveys is less than 0.2.:  

Null hypothesis:[tex]p\geq 0.2[/tex]  

Alternative hypothesis:[tex]p < 0.2[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Calculate the statistic  

Since we have all the info required we can replace in formula (1) like this:  

[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]  

Statistical decision  

The next step would be calculate the p value for this test.  

Since is a left tailed test the p value would be:  

[tex]p_v =P(z<-3.137)=0.0009[/tex]  

Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%

We formulate a null and alternative hypothesis about the survey return rate. Then, given the returned survey and total survey counts, we calculate a sample proportion, standard deviation, and a z-score. Using this z-score, we compute a p-value, which is checked against the given significance level to make a decision about the hypothesis.

In this scenario, we are interested in whether the cell phone survey return rate is less than 20%. So we can set our null hypothesis (H0) as: The return rate is 20% or more, and our alternative hypothesis (Ha) as: The return rate is less than 20%.

Given that 12961296 surveys were returned out of 6997, we can compute the sample proportion (p). Then, we calculate the standard deviation (sd) of the sampling distribution of the proportion (assuming H0 is true - i.e., the proportion in the population is 20%).

Using this sd and the sample proportion, we can calculate the z-score. The p-value would be the probability of getting a z-score as extreme as what we got, assuming H0 is true. If the p-value is less than the significance level (0.01), we would reject the null hypothesis. If it's higher, we fail to reject the null.

Note: Due to the likely typographical error in the given number of returned surveys, the precise computation cannot be done here.

Answer: D - 2/3 x- 13/12 = -5/12 x

Step-by-step explanation:

The equivalent equation is 'Two-thirds x equals negative StartFraction 5 Over 12 EndFraction x minus StartFraction 7 Over 12 EndFraction'. This is achieved by adding and subtracting appropriate fractions on both sides of the original equation to balance it.

The question asks which equation is equivalent to 'Two-thirds x minus StartFraction 5 Over 6 EndFraction equals negative StartFraction 5 Over 12 EndFraction x + one-fourth'. The correct equivalent equation for this is 'Two-thirds x equals negative StartFraction 5 Over 12 EndFraction x minus StartFraction 7 Over 12 EndFraction'.

To find this, take the original equation, and add StartFraction 5 Over 6 EndFraction to both sides which will result in Two-thirds x equals negative StartFraction 5 Over 12 EndFraction x plus one-fourth. Then, subtract one-fourth from both sides, resulting in 'Two-thirds x equals negative StartFraction 5 Over 12 EndFraction x minus StartFraction 7 Over 12 EndFraction'.

Answer: The area is 19.625 cm^2

Step-by-step explanation:

For the area of a circle, the equation is:

A = pi*r^2

where pi = 3.14 and r is the  radius of the circle, and the radius is half the diameter.

We have that the diameter is 5 cm, then the radius is:

r = 5cm/2 = 2.5 cm

Then the area is

A = 3.14*(2.5cm)^2 = 19.625 cm^2

Answer:

[tex]19.63 cm^2[/tex]

Final answer:

The volume of the pyramid can be found using the formula V = (1/3) * B * h, where B is the area of the base and h is the height of the pyramid. Plugging in the given values, the volume is 60 cubic inches.

Explanation:

To find the volume of a square pyramid, you can use the formula V = (1/3) * B * h, where V represents the volume, B represents the area of the base, and h represents the height of the pyramid.

In this case, the base is a square, so the area of the base is side * side. Since the base edge is 6 inches, the area of the base is 6 * 6 = 36 square inches.

Plugging in the values for B and h into the formula, we get V = (1/3) * 36 * 5 = 60 cubic inches.

Answer:

27%

Step-by-step explanation:

Add the number of students: 87+86+71+92= 336

Divide the number of 9th grade Spanish students by the total number of students: 92÷336= 0.27

Times by 100 to get a percentage: 27%

Final answer:

To find the percentage of 9th graders taking Spanish compared to all students in foreign language classes, add the counts from all classes to find the total, then divide the number of 9th grade Spanish students by this total and multiply by 100.

Explanation:

To determine the percent of all students in a foreign language class that are 9th graders taking Spanish, we would need the total number of students taking foreign languages and the number of those who are 9th graders taking Spanish. Let's assume we have the following numbers in our data table:

8th grade French students

9th grade French students

8th grade Spanish students

9th grade Spanish students

Add the numbers of all the students together to find the total. Then, divide the number of 9th grade Spanish students by the total and multiply by 100 to get the percentage.

For example, if there are 100 students in total and 27 of them are 9th graders taking Spanish, the calculation would be:

(27 / 100) * 100% = 27%

The probability of getting the same colour twice when a fair spinner with 10 sections (3 red, 4 blue, 3 green) is spun twice is 34%.

This question is about the concept of probability in Mathematics. Since the spinner is spun twice and we want the same colour both times, we need to calculate the probability for each colour and then add them together.

There are 10 sections in total on the spinner, with 3 being red, 4 being blue, and 3 being green:

So the total probability of getting the same colour twice is 9/100 + 16/100 + 9/100 = 34/100 = 0.34 or 34%.
