What is the constant of proportionality as shown in the graph?
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

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.

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,
Diane is making chair covers to sell. She has a bolt of fabric that is 20 yards long. If each chair requires 3 2/5 yards of fabric, how many chair covers will Diane be able to make
Answer: alo mwen panse ke li ta dwe 3/6
Step-by-step explanation:
ou konnen mwen te u konsa 7 ajoute ke epi pou yo jwenn 10 shawty
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.

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]

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

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]

y = -x-5
Slope of line is -1.
Slope of perpendicular to line is 1.
Point-slope equation for line of slope 1 that passes through (6,2):
y-2 = 1(x-6)
Rearrange equation to slope-intercept form:
y = 1(x-6) + 2
