Select from the drop-down menus to complete the statement.
The percent of seventh graders surveyed who prefer fiction is ____ the percent of eighth graders surveyed who prefer fiction.
A. greater than
B. less than
C. equal to
Answers
8th graders prefer fiction is 0.68 = 68%
7th graders is greater than 8 graders
answer
A. greater than
Answer:
Option A. greater than
Step-by-step explanation:
The percent of seventh graders surveyed who preferred fiction = 0.75 or 75%
The percent of eight graders surveyed who preferred fiction = 0.68 or 68%
Now we can say the percentage of seventh graders who preferred fiction is GREATER THAN the percentage of eight graders who preferred fiction.
Therefore option A. is the correct option.

If Jamal borrowed $625 from his brother for 8 years and later paid $830 then he must have taken it at the simple rate of 4.1%.
What is simple rate of interest?The interest which is not calculated on the aggregate interest or which is calculated only on principal amount is known as simple interest.
How to determine rate of interest?The principal amount is $625 and the number of years is 8 and we have to find the rate of interest.
The amount which is ultimately paid is equal to principal and interest. So,
830=625+625*r/100*8
830-625=625*r/100*8
205=625*r/100*8
205*100/625*8=r
20500/5000=r
r=4.1%
Hence if the principal amount is $625 and the amount lastly paid is $830 then the rate of interest is 4.1% which is option B.

Graph the linear equation find three points that solve the equation then plot on the graph x-3y=-6 plz help
Answers
The linear equation x - 3y = -6 can be rearranged as y = (1/3)x + 2. By substituting x-values of 0, 3, and 6, we obtained three points (0,2), (3,3), and (6,4). Plotting these points to graph helps us to visualize the equation.
Explanation:The original linear equation is x - 3y = -6. We can rearrange this equation to y = (1/3)x + 2. From this, we can derive three points on the graph. For example, let's calculate the y-values for x = 0, 3, and 6, which are easy to use.
For x = 0, the equation becomes y = (1/3)(0) + 2 = 2. So, the point (0,2) lies on this line.
For x = 3, the equation becomes y = (1/3)(3) + 2 = 3. So, the point (3,3) is on the line. For x = 6, the y-value is y = (1/3)(6) + 2 = 4, giving us the point (6,4).
These three points can be plotted on a graph and a line can be drawn through them to graph the equation.

Miguel wants to rent a boat and spend at most $52. The boat costs $7 per hour, and Miguel has a discount coupon for $4 off. What are the possible numbers of hours Miguel could rent the boat?
Use t for the number of hours- write your answer as an inequality solved for t. this is due today plz help thank you!
Answers
"At most" is equivalent to "less than or equal to". So the inequality is going to involve the less than or equal to symbol. The boat costs $7 per hour and that can be represented by:
7t
A discount coupon means subtracting $4 from the 7t:
7t - 4
When these are placed with the inequality:
7t - 4 ≤ 52
Solving this inequality means isolating the variable. To do this, adding 4 to both sides will be the first step.
7t ≤ 56
Finally, dividing both sides by 7 will get the final answer of 8, meaning the possible number of hours Miguel could rent the boat is no more than (less than or equal to) 8.

How many ways can a jury of four men and three women be selected from twelve men and ten women
Answers
Since the events are independent of each other (choosing one does not influence the chance of choosing the others) we multiply the combinations.
The first combination is [tex]_1_2C_4[/tex], because we are selecting 4 men from a possible 12.
The second combination is [tex]_1_0C_3[/tex], because we are selecting 3 women from a possible 10.
Multiplying these we have: [tex]_1_2C_4 \times _1_0C_3 \\ \\=\frac{12!}{4!8!} \times \frac{10!}{3!7!} \\ \\=\frac{479001600}{967680} \times \frac{3628800}{30240} \\ \\=495 \times 120 \\ = 59400[/tex]
Final answer:
The number of ways to choose the jury is 59,400.
Explanation:
The question is concerned with a combinatorial problem of selecting a jury from a larger pool of people, which is a classic example of the use of combinations in probability and statistics.
To find out how many ways we can select a jury of four men from twelve men, and three women from ten women, we use the combination formula which is C(n, k) = n! / (k! * (n-k)!), where '!' represents factorial, 'n' is the total number of people, and 'k' is the number of people to choose.
To select the men, we calculate the combinations as follows:
C(12, 4) = 12! / (4! * (12-4)!) = 495 waysTo select the women, we calculate the combinations as follows:
C(10, 3) = 10! / (3! * (10-3)!) = 120 waysTo find the total number of ways to select the jury of four men and three women, we multiply the number of ways to choose the men by the number of ways to choose the women:
495 ways (to choose men) * 120 ways (to choose women) = 59,400 different ways to select the jury.

Arlene sells computers and tables. She earns 8% commission on every dollar of sales that she makes
Answers
Answer:
equation is: 0.08x = 2560
Total sales = $32,000
Explanation:
Assume that the total sales for the month is x.
Now, we are given that:
Her commission is 8% for each dollar and that she made a total of $2560 in commission.
This means that:
8% of x = 2560
8% * x = 2560
0.08x = 2560 ...........> required equation
Now, after getting the equation, we can solve for x to get the total sales as follows:
0.08x = 2560
x = 2560 / 0.08
x = 32,000
This means that her total sales for the month is $32,000

Since we know the values of the radius and the height (and we know Pi = 3.14), we can plug these in to our formula and solve to find the surface area:
A = 2 (3.14) (16) (9) + 2 (3.14) [tex] 16^{2} [/tex]

josè and nancy take care of animals when the owners are away. josè charges $15 plus $2 per animal. nancy charges $5 plus $3 per animal. for how many animals do they charge the same amount? write a system of equation to model the problem and solve the system to find out.
Answers
José and Nancy would charge the same amount for taking care of 10 animals. This is found by solving the system of equations which represents their respective charges.
Explanation:The subject of this problem is determining for how many animals José and Nancy would charge the same amount. This is a classic algebra problem that can be solved by setting up a system of equations.
Let's designate 'x' as the number of animals. José's charges can be represented by the equation y = 15 + 2x, because he charges a flat fee of $15 and then an additional $2 per animal. Nancy's charges can be represented by the equation y = 5 + 3x, because her initial fee is $5, and she charges an additional $3 per animal.
To find out when they both charge the same amount, set these two equations equal to each other and solve for x:
15 + 2x = 5 + 3x
This simplifies to 10 = x, meaning they would both charge the same amount for 10 animals.
