Answer:
c=36p+36
Step-by-step explanation:
Okay so the cost of the meal without tip is $36. To find the tip, we would multiply p by 36. To find our total (c), we would add this (36p) to the original 36.
In other words:
c=36p+36
(can also be written as c=36(1+p) )

Answer:
Question 15: x = 17
Question 16: area = 5610 units
Step-by-step explanation:
Question 15:
The perimeter is the sum of all sides of a triangle.
It is given that the perimeter is 374 units.
[tex]p = 8x - 4 + 9x + 4 + 4x + 17[/tex]
[tex]374 = 8x - 4 + 9x + 4 + 4x + 17[/tex]
Add all the like terms.
[tex]374 = 21x + 17[/tex]
Subtract 17 from both sides.
[tex]357 = 21x[/tex]
Divide by 21 from both sides.
[tex]17 = x[/tex]
Question 16:
The area of a triangle can be found by using the following formula:
[tex]a = \frac{1}{2} bh[/tex]
(where a is the area, b is the base, and h is the height)
Using the value of x you just found previously (17), you can calculate the base and height by substituting 17 with x in their respective equations.
[tex]h = 8x - 4[/tex]
[tex]h = 8(17) - 4[/tex]
[tex]h = 134[/tex]
[tex]b = 4x + 17[/tex]
[tex]b = 4(17) + 17[/tex]
[tex]b = 85[/tex]
Now that you found the base and height, substitute the values, 134 and 75, into the area of a triangle formula.
[tex]a = \frac{1}{2} bh[/tex]
[tex]a = \frac{1}{2} (85)(132)[/tex]
[tex]a = 5610[/tex]
write the 0.216 in the form of p by q
Answer:
27/125
Step-by-step explanation:
Given the decimal value 0.216, we are to express as a fraction in the fofrm of p/q
0.216 = 216/1000
216/1000 = 2 * 108/2 * 500
216/1000 = 108/500
108/500 = 4*27/4*125
108/500 = 27/125
Hence the expression in form p by q is 27/125

The mean, as a measure of location, would be inappropriate for which of the following? A. Ages of adults at a senior citizen center. B. Number of pages in textbooks on statistics. C. Incomes of lawyers. D. Marital status of college students at a university.
Answer:
D. Marital status of college students at a university.
Step-by-step explanation:
The mean, as a measure, is appropriate when we are dealing with quantitative measures, that is, the measure that we are dealing with is a number.
In this question:
Options A(age), B(number of pages) and C(income) are all quantitative, so the mean is appropriate.
In Option D, the marital status is a qualitative measure(married, dating, single), so the mean is innapropriate, and this is the answer,

What is number series?A number series is a sequence of numbers that follow a specific pattern or rule. The pattern can be based on a mathematical formula or a logical rule, such as adding or subtracting a fixed amount, multiplying or dividing by a constant, or using a combination of operations.
To find the multiples of 1/4, we can multiply it by whole numbers:
1/4 x 1 = 1/4
1/4 x 2 = 2/4 = 1/2
1/4 x 3 = 3/4
1/4 x 4 = 4/4 = 1 (which is equivalent to 4/4)
Therefore, the next four multiples of 1/4 are:
1/2, 3/4, 1, 5/4.

find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and radius of the base is 7 cm
Answer:
[tex]CSA = 660cm^2[/tex] --- Curved Surface Area
[tex]TSA = 968cm^2[/tex] --- Total Surface Area
Step-by-step explanation:
Given
Shape: Cylinder
[tex]h = 15[/tex] -- height
[tex]r = 7[/tex] --- radius
Solving (a): The curved surface area (CSA)
This is calculated as:
[tex]CSA = 2\pi rh[/tex]
This gives:
[tex]CSA = 2 * \frac{22}{7} * 7 * 15[/tex]
[tex]CSA = 2 * 22* 15[/tex]
[tex]CSA = 660cm^2[/tex]
Solving (b): The total surface area (TSA)
This is calculated as:
[tex]TSA = 2\pi r(h + r)[/tex]
This gives:
[tex]TSA = 2 * \frac{22}{7} * 7 * (15 + 7)[/tex]
[tex]TSA = 2 * 22 * (15 + 7)[/tex]
[tex]TSA = 2 * 22 * 22[/tex]
[tex]TSA = 968cm^2[/tex]

The number of chair covers Diane will be able to make is 5.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Length of the fabric = 20 yards
Length of fabric needed for each chair cover = 3(2/5) yards
The number of chair covers that can be made with 20 yards.
= 20 ÷ 3(2/5)
= 20 ÷ 17/5
= 20 x 5/17
= 100/17
= 5.8
= 5
Thus,
The number of chair covers is 5.

Suppose that a random sample of 10 adults has a mean score of 62 on a standardized personality test, with a standard deviation of 4 . (A higher score indicates a more personable participant.) If we assume that scores on this test are normally distributed, find a 90% confidence interval for the mean score of all takers of this test. Then find the lower limit and upper limit of the 90% confidence interval.
Answer:
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.9}{2} = 0.05[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.05 = 0.95[/tex], so [tex]z = 1.645[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.645*\frac{4}{\sqrt{10}} = 2.08[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 62 - 2.08 = 59.92
The upper end of the interval is the sample mean added to M. So it is 62 + 2.08 = 64.08.
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
