Step-by-step explanation:
The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
A. -3n + 27
B. -3(27) = n
C. -3n = 27
D. -3 = 27n
Answer:
C
Step-by-step explanation:
If that's wrong it's D
Answer:
C.
Step-by-step explanation:
If it is a product, that is a way to say that it is multiplication. Since the product is 27, the answer is 27. So what multiplied by -3 equals to 27? To write this, you have to multiply -3 by n to get 27.

Step-by-step explanation:
Hey there!
Looking through figure; we find that,
angle 7 + 38° = 180° { Being linear pair}
Or, angle 7 = 180° - 38°
Angle 7 = 142°
Therefore, the measure of angle 7 is 142°.

1. Solve 2x < 10. Explain how to find the solution set.
Answer:
x<5
Step-by-step explanation:
you need to divide 2x by 2 which gives you x. then you do the same to the other side so (10/2) which gives you 5. this means x can be any number under 5 in order for the function to be true.
How do you do this question?
Answer:
R = 1
I = [-1, 1)
Step-by-step explanation:
Use the ratio test:
lim(n→∞)│aₙ₊₁ / aₙ│
lim(n→∞)│[xⁿ⁺¹ / (8(n+1) − 1)] / [xⁿ / (8n − 1)]│
lim(n→∞)│[xⁿ⁺¹ / (8n + 7)] × [(8n − 1) / xⁿ]│
lim(n→∞)│[x (8n − 1) / (8n + 7)]│
lim(n→∞)│[(8n − 1) / (8n + 7)]││x│
│x│
The series converges if the limit is less than 1.
│x│< 1
So the radius of convergence is 1.
Solving for x:
-1 < x < 1
Check the endpoints.
If x = -1, the series is ∑ (-1)ⁿ / (8n − 1), which converges.
If x = 1, the series is ∑ 1 / (8n − 1), which diverges.
So the interval of convergence is [-1, 1).

What are polynominal function? Can you please explain in a easy way to understand thank you
Answer:
A polynomial function is a relationship that provides a value that is determined by a polynomial for each input value.
Explanation:
A polynomial is a mathematical expression constructed with constants and variables using the four operations:
Polynomial Example Degree
Constant 1 0
Linear 2x+1 1
Quadratic 3x2+2x+1 2
Cubic 4x3+3x2+2x+1 3
Quartic 5x4+4x3+3x2+2 x+1 4
In other words, we have been calculating with various polynomials all along. When two polynomials are divided it is called a rational expression.
In such cases you must be careful that the denominator does not equal zero. Division by zero is not defined and thus x may not have a value that allows the denominator to become zero. Otherwise, any other value may be substituted for x.
Example
x3−x6−x
x must not have the value of 6 since 6-6=0.

In a sample of 63 cans, the average diameter was found to be 3.7in. with a standard deviation of 0.32. Give a point estimate for the population variance of the diameter of the cans
Answer:
0.32
Step-by-step explanation:
Given that:
The sample size of the population = 63
The sample mean = 3.7
The sample standard deviation = 0.32
Thus, the point estimate for the population variance of the diameter of the cans is said to be the standard deviation of the population = 0.32
Suppose the variance (S²) is given as 0.32
Then the standard deviation will be [tex]\sqrt{S^2}[/tex]
=[tex]\sqrt{0.32}[/tex]
= 0.57
Then, since the sample standard deviation is the point estimate, we would have had 0.57 as the answer.

There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold
Answer:
29
Step-by-step explanation:
345 tickets = 345 x 7.50 = £2587.5 this means 345 - 374 = 29
how to get 374:
17 x 22 = 374
29 tickets were not sold.
Given that,
There are 17 rows of seats in a cinema.
There are 22 seats in each row.
Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold?
According to the question,
There are 17 rows of seats in a cinema.
There are 22 seats in each row.
Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
Then,
Total number of seats is,
= 17 x 22 = 374
Number of tickets sold = £2587.50 / £7.50 = 345
Therefore,
45 people filled 345 seats
Unoccupied seats = 374 - 345 = 29
Therefore, 29 tickets were not sold.

As preparation for designing a new line of business wear, a clothing manufacturer asked a large sample of department store customers, "What is your favorite color of dress shirt?" The pie chart below summarizes their responses. (a) Which color was chosen by approximately one-eighth of the customers? Select One Black Grey (b) Approximately what percentage of the customers chose White or Blue? Write your answer as a multiple of 10% - that is, 10%, 20% Pink 30%, Other Blue White (c) I 24% of the customers chose Black, approximately what percentage chose Other? 8% 16% 339
Answer:
The pie chart is missing, so I looked for similar questions (see attached image):
(a) Which color was chosen by approximately one-eighth of the customers?
Blue. There are two colors that represent approximately 15%, and they are blue or grey, but grey is a little larger so it is closer to 20%.(b) Approximately what percentage of the customers chose White or Blue?
40%. If you combine the approximate number of customers that chose either white or blue, you will get roughly 40%(c) If 24% of the customers chose Black, approximately what percentage chose Other?
In all the similar questions that I found black is much more than 24%, it clearly makes up more than 1/4 of the pie chart. I would say approximately 33%. In the attached image you can see that "other" represents between 6-7%.The easiest way to solve this is to print the image and use a protractor. If you want to calculate the area for blue, just measure the angle, e.g. ± 55°, then divide by 360° = 0.1528 = 15.28%.
