The percentage of respondents from the 46-55 age group who rated the film excellent is 20 %.
To determine the percentage of respondents from the 46-55 age group who rated the film excellent, you need two pieces of information: the number of respondents in that age group who rated the film excellent and the total number of respondents in that age group. The formula for calculating the percentage is:
[tex]\[ \text{Percentage} = \left( \frac{\text{Number of respondents who rated excellent}}{\text{Total number of respondents in the age group}} \right) \times 100 \][/tex]
Assuming you have these numbers, let's denote the number of respondents who rated the film excellent in the 46-55 age group as X and the total number of respondents in that age group as Y. The formula becomes:
[tex]\[ \text{Percentage} = \left( \frac{X}{Y} \right) \times 100 \][/tex]
For example, if 20 respondents in the 46-55 age group rated the film excellent out of a total of 100 respondents in that age group, the calculation would be:
[tex]\[ \text{Percentage} = \left( \frac{20}{100} \right) \times 100 = 20\% \][/tex]
Therefore, replace X and Y with the actual numbers from your data to find the specific percentage.

Which right triangular prism has the greatest volume?
Answer:
So Prism D has the greatest volume.
Step-by-step explanation:
Since volume of a triangular prism = A × h
where A = Area of base of prism
h = height
For prism (A) ⇒ Volume = ( 6 × 7 ) × 9
= 42 × 9 = 378m³
Prism (B) ⇒ Volume = ( 5 × 6 ) × 13
= 30 × 13 = 390m³
Prism (C) ⇒ Volume = ( 11 × 8 ) × 8
= 88 × 8 = 704m³
Prism (D) ⇒ Volume = ( 10 × 8 ) × 9
= 80 × 9 = 720m³
So prism D has the maximum volume.

two boats start at the same point and speed away along courses that form 110 degree angle. if one boat travels at 24 miles per hour and the other boat travels at 32 miles per hour. how far apart are the boats after 30 minutes?
A. 21 miles
B. 22 miles
C. 23 miles
D. 24 miles
E. 25 miles
The distance between the boats after 30 minutes is approximately 23.04 miles. Option C
How to find the distance between the two boats after 30 minutesTo find the distance between the two boats after 30 minutes, use the law of cosines. Let's denote the distance between the boats as "d".
We know that one boat is traveling at 24 miles per hour, and the other boat is traveling at 32 miles per hour. In 30 minutes (or 0.5 hours), the first boat would have traveled 24 * 0.5 = 12 miles, and the second boat would have traveled 32 * 0.5 = 16 miles.
Now, applying the law of cosines:
[tex]d^2 = (12)^2 + (16)^2 - 2 * 12 * 16 * cos(110^o)[/tex]
Calculating the equation:
[tex]d^2 = 144 + 256 - 384 * cos(110^o)[/tex]
Now, evaluate cos(110°):
cos(110°) ≈ -0.34202
Substituting the value:
[tex]d^2[/tex] = 144 + 256 - 384 * (-0.34202)
[tex]d^2[/tex] = 144 + 256 + 131.23808
[tex]d^2[/tex] ≈ 531.23808
Taking the square root:
d ≈ 23.04
Therefore, the distance between the boats after 30 minutes is approximately 23.04 miles.
Rounded to the nearest whole number, the answer would be 23 miles (Option C).

Tell whether the study is an experimental study or an observational study.
You want to study the effects of regular exercise on a person’s heart rate. You measure the heart rate of a person at rest and again after jogging in place for 5 minutes. The control group is every other student who enters the room. The experimental group is those students who are not in the control group.
Final answer:
The study described is an experimental study. The independent variable is regular exercise and the dependent variable is the person's heart rate. The control group is the group of students who do not exercise, while the experimental group is the group of students who engage in regular exercise.
Explanation:
The study described is an experimental study.
In an experimental study, the researcher directly manipulates the independent variable to determine its effect on the dependent variable. In this case, the independent variable is regular exercise and the dependent variable is the person's heart rate.
The control group is the group of students who do not exercise, while the experimental group is the group of students who engage in regular exercise. By comparing the heart rates of the two groups before and after exercise, the researcher can determine the effects of exercise on heart rate.

Jacqueline is deciding between two mortgages for her new home. The first mortgage is an 80/20 mortgage with interest rates of 4.75 and 7.525%, respectively. The second mortgage is a 30-year mortgage with a 5.25% and a $58.30 monthly PMI. If the house price is $145,000, which mortgage payment will be lower initially, and by how much?
Final answer:
The initial payment for the first mortgage will be lower by $409.07.
Explanation:
To determine which mortgage payment will be lower initially and by how much, let's calculate the monthly payments for each option.
First Mortgage: 80/20 Mortgage
The first mortgage has two parts, with interest rates of 4.75% and 7.525% respectively. Assuming a house price of $145,000, the loan amount for the first part is 80% of $145,000 = $116,000, and the loan amount for the second part is 20% of $145,000 = $29,000.
Monthly payment for the first part: Principal * Monthly interest rate = $116,000 * (4.75% / 12) = $463.33
Monthly payment for the second part: Principal * Monthly interest rate = $29,000 * (7.525% / 12) = $183.23
Total monthly payment for the first mortgage: $463.33 + $183.23 = $646.56
Second Mortgage: 30-Year Mortgage with PMI
The second mortgage is a 30-year mortgage with an interest rate of 5.25% and a $58.30 monthly PMI.
Loan amount for the second mortgage: $145,000
Monthly payment for the second mortgage: Principal * Monthly interest rate + PMI = $145,000 * (5.25% / 12) + $58.30 = $1,055.63
Therefore, the initial payment for the first mortgage will be lower by $1,055.63 - $646.56 = $409.07.
Jacqueline's first mortgage option has a lower initial monthly payment of $808.04 compared to the second option's $859.69, making it $51.65 cheaper monthly.
Jacqueline is choosing between two mortgage options for a $145,000 house. Let's compare the monthly payments for each mortgage.
Option 1: 80/20 Mortgage
This option involves two loans: the first for 80% of the house price ($116,000) at 4.75%, and the second for 20% ($29,000) at 7.525%.
First loan monthly payment: Use the formula for the monthly payment on a mortgage:Option 2: 30-year Mortgage
Total loan amount: $145,000, PMI = $58.30Calculate mortgage payment using the same formula: P = $145,000, r = 5.25%/12 = 0.004375, n = 30*12 = 360Monthly payment before PMI: $801.39Total second option monthly payment: $801.39 + $58.30 = $859.69Now, comparing the two, the first option has an initial monthly payment of $808.04, while the second option has an initial monthly payment of $859.69. So, the first mortgage payment is lower by $51.65.

What rate of simple interest is needed for $700 to double, in 3 years?
The rate of simple interest required for $700 to double in 3 years is found using the formula I=PRT. In this scenario, the rate comes out to be approximately 33.3%.
Explanation:The subject of this question is finding the rate required for simple interest to cause an investment of $700 to double in a duration of 3 years.
Generally, we use the formula for simple interest: I=PRT where P is the principal amount (700 in this case), I is the interest earned, R is the rate we want to find and T is the time period in years.
However, since the aim is for the $700 to double, the interest earned will be an additional $700, thereby making the total $1400. Thus, substituting these values into the formula, we get 700 = 700 * R * 3. Simplifying this, we find that R = 700/(700*3) = 1/3 or approximately 33.3%.
Hence, the rate of simple interest required for $700 to double in 3 years is approximately 33.3%.

R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.
To find out the simple interest rate that is needed for $700 to double in 3 years, we can set up the equation based on the formula for simple interest, which is I = PRT (where I is the interest, P is the principal amount, R is the rate of interest, and T is the time period in years).
Since the student wants the money to double, the interest gained should be equal to the principal, which means I = $700. The time given is T = 3 years. Plugging these values into our formula, we get:
$700 = $700 × R × 3
By dividing both sides by $2100 ($700 ×3), the equation simplifies to:
R = $700 / $2100
Therefore, R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.
