Answers
The value of X is -3.
please see the attached picture for full solution
Hope it helps
Good luck on your assignment
Answer:
\(x = - 3\)
Step-by-step explanation:
\( - 8(x + 6) - 1 = 5(x - 2) \\ - 8x - 48 - 1 = 5x - 10 \\ - 8x - 5x = 48 + 1 - 10 \\ - 13x = 39 \\ \frac{ - 13x}{ - 13} = \frac{39}{ - 13} \\ x = - 3\)
hope this helps

Answers
The percent of people of the people surveyed were satisfied with the car is the percent of people of the people would buy that type of car again, so we have: 2015 ÷ 3100 × 100% = 65%
ANSWER: 65%
Ok done. Thank to me :3

What is the answer to 5 * 3(3 + 6^2) + 12?
Answers
Answer:
The answer is 1677.
To solve the expression, we must follow the order of operations:
1. First, we must calculate the power of 6:
6^2 = 36
2. Then, we must solve the expression inside the parentheses:
3 + 36 = 39
3. Next, we multiply 3 by 39:
3 × 39 = 117
4. We multiply 5 by 117:
5 × 117 = 585
5. Finally, we add 12 to 585:
585 + 12 = 597
Therefore,
5 * 3(3 + 6^2) + 12 = 597.

Answers
Answer:
A- 7.4 ⋅ 10−4 mm
Step-by-step explanation:
Well, to solve this problem, we must convert the number and / or the units in a more imaginable one.
We are given two choices:
a. 7.4 x 10^-4 mm
b. 7.4 x 10^4 mm
Converting the units and numbers into meters and general form, respectively. (What is meant by general form is not to write it in scientific notation).
a. 7.4 x 10^-4 mm (1 m / 1000 mm) = 0.00000074 m
b. 7.4 x 10^4 mm (1 m / 1000 mm) = 74 m
Now comparing the two values above, what do you think is the distance between the tracks on a DVD? Definitely NOT 74 m or else the DVD is extremely big. Therefore the correct is the smaller one.

A college cafeteria is looking for a new dessert to offer its 5,000 students. The table shows the preference of 225 students.
Ice Cream Candy Cake Pie Cookies
81 9 72 36 27
Which statement is the best prediction about the scoops of ice cream the college will need?
The college will have about 1,800 students who prefer ice cream.
The college will have about 800 students who prefer ice cream.
The college will have about 600 students who prefer ice cream.
The college will have about 144 students who prefer ice cream.
I did C but I got it wrong so what is it?
Answers
To determine the best prediction about the number of students who prefer ice cream, let's analyze the data provided in the table. According to the table, out of the 225 surveyed students:
Ice Cream: 81 students
Candy: 9 students
Cake: 72 students
Pie: 36 students
Cookies: 27 students
To estimate the number of students who prefer ice cream among the 5,000 total students, we can use the proportions:
Ice Cream proportion = (Number of Ice Cream preference) / (Total surveyed students)
Ice Cream proportion = 81 / 225
To estimate the number of students who prefer ice cream among the 5,000 total students, we can multiply the Ice Cream proportion by the total number of students:
Estimated number of Ice Cream preferences = Ice Cream proportion * Total students
Estimated number of Ice Cream preference = (81 / 225) * 5000
Calculating the estimated number of students who prefer ice cream:
Estimated number of Ice Cream preference = (0.36) * 5000
Estimated number of Ice Cream preferences ≈ 1800
Therefore, the best prediction about the scoops of ice cream the college will need is:
The college will have about 1,800 students who prefer ice cream.
So, option A is the correct answer.

Step-by-step explanation:
a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

please just make it simple i dont need an explanation i need a answer i can put into my school test
Answers
Sure, I can help you with that.
**Part A: Calculate the measures of center.**
The measures of center are the mean, median, and mode.
* **Mean:** The mean is calculated by adding all the values in the data set and dividing by the number of values. For the Sky View School data set, the mean is 5.8. For the South Lake School data set, the mean is 5.4.
* **Median:** The median is the middle value in the data set when the values are arranged in increasing order. For the Sky View School data set, the median is 6. For the South Lake School data set, the median is 5.5.
* **Mode:** The mode is the most frequent value in the data set. For the Sky View School data set, the mode is 5. For the South Lake School data set, the mode is 5.
**Part B: Calculate the measures of variability.**
The measures of variability are the range, standard deviation, and variance.
* **Range:** The range is the difference between the largest and smallest values in the data set. For the Sky View School data set, the range is 8. For the South Lake School data set, the range is 8.
* **Standard deviation:** The standard deviation is a measure of how spread out the data is. The larger the standard deviation, the more spread out the data is. For the Sky View School data set, the standard deviation is 1.7. For the South Lake School data set, the standard deviation is 1.5.
* **Variance:** The variance is the square of the standard deviation. For the Sky View School data set, the variance is 2.89. For the South Lake School data set, the variance is 2.25.
**Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning.**
If you are interested in a smaller class size, then the South Lake School is a better choice. The average class size at the South Lake School is 5.4, while the average class size at the Sky View School is 5.8. Additionally, the median class size at the South Lake School is 5.5, while the median class size at the Sky View School is 6. This means that half of the classes at the South Lake School have 5 or fewer students, while half of the classes at the Sky View School have 6 or more students.

On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answers
Answer: 81 miles
Step-by-step explanation:
The total distance traveled on the three-day trip is: 81 miles.
How did we get the value?Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:
a. (5/8)D1 + 15 = D1
(3/8)D1 = 15
D1 = 40 miles
So, the total distance traveled on Day 1 is 40 miles.
b. 18 + (2/5)D2 = D2
(3/5)D2 = 18
D2 = 30 miles
So, the total distance traveled on Day 2 is 30 miles.
c. (5/11)D3 + 6 = D3
(6/11)D3 = 6
D3 = 11 miles
So, the total distance traveled on Day 3 is 11 miles.
Therefore, the total distance traveled on the three-day trip is:
40 + 30 + 11 = 81 miles.
