Answer:
Step-by-step explanation:
I can't find the mean absolute value. But the absolute value is never negative unless there is a minus sign outside the absolute value bars.
So the mean is those 5 salaries added and then divide by 5
28
21.8
21.1
19
15.5
Total 105.4
The mean = 105.4 / 5 = 21.08
The absolute mean is the same thing. Both are plus. If you have a definition for the mean absolute value, please post it and I'll come back and edit my answer.

The ratio of seventh graders to eighth graders at junior high school is 9:10. If there is 90 eighth graders, how many seventh graders would be there?
Answer:
81
Step-by-step explanation:
To find the base unit of the ration, divide 90 by 10, which is 9. Then multiply 9 (the base unit) by 9 (the ratio of the seventh graders) and that equals 81
Use the Venn diagram to calculate probabilities.
Circles A, B, and C overlap. Circle A contains 12, circle B contains 11, and circle C contains 4. The overlap of A and B contains 5, the overlap of B and C contains 3, and the overlap of C and A contains 6. The overlap of the 3 circles contains 8.
Which probabilities are correct? Select two options.
P(A|C) = Two-thirds
P(C|B) = StartFraction 8 Over 27 EndFraction
P(A) = StartFraction 31 Over 59 EndFraction
P(C) = Three-sevenths
P(B|A) = StartFraction 13 Over 27 EndFraction
Answer:
The first one
The fourth one
Step-by-step explanation:
Draw a venn diagram (see picture)
A|C= (A∩C)/C
(6+8)/(6+8+3+4)= 2/3
C|B= (C∩B)/B
(8+3)/(11+5+8+3)= 11/27
A=(12+5+8+6)/(11+5+8+3+4+6+12) = 31/49
C= (4+6+8+3)/(12+5+11+6+8+3+4)= 3/7
P(B|A)= (B∩A)/A
(5+8)/(12+5+6+8) = 13/31

If x is a positive integer, for how many different values of x is StartRoot StartFraction 48 Over x EndFraction EndRoot a whole number? 2 3 6 10
Answer:
3
Step-by-step explanation:
According To the Question,
Given that, 'x' is a positive integer . And We have to find the number of different values of 'x', So that the value of [tex]\sqrt{\frac{48}{x} }[/tex] is a Whole number.Then First, we have to find those values of 'x' for which the given fraction is a square.
We Know, All the factors of 48 are {1,2,3,4,6,8,12,16,24,48} .
Now, From the above factors, only (3,12 & 48) can give us a square number.
Therefore,
If x=3, Then [tex]\sqrt{\frac{48}{3} } = \sqrt{16}[/tex] ⇒ 4If, x=12, Then [tex]\sqrt{\frac{48}{12} } = \sqrt{4}[/tex] ⇒ 2If, x=48, Then [tex]\sqrt{\frac{48}{48} } = \sqrt{1}[/tex] ⇒ 1Thus, There are 3 whole numbers (3,12,48).

Which equation correctly shows that (x^2)^4=x^8?
Answer: The answer is D
because x^2^4 power is x^8 and x^2*x^2*x^2*x^2 which is 2+2+2+2 which is x^8
Step-by-step explanation:
it is not C because it would be 4(c^2) which is 4x^2
it is not A because (x^2)(x^4) is 2+4 which is 6 so that means it would be x^6
The exponent equation correctly shows that [tex](x^{2} )^{4}=x^{8}[/tex] is
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] = [tex]x[/tex] × [tex]x[/tex] ×[tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] = [tex]x^{8}[/tex]
Option (D) is correct
What is an exponent law?Exponents are also called powers or indices. The exponent rules explain how to solve various equations that as you might expect have exponents in them. They are several different kinds of exponent equations.
Given exponent equation
[tex](x^{2} )^{4}=x^{8}[/tex]
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex]
If the bases are same, then the powers should be added from an exponent law. It is called as product of powers rule.
[tex](a^{m} )^{n} = a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{m+n}[/tex]
By adding the power, we get
2+2+2+2 = 8
∴ [tex](x^{2} )^{4} =x^{2+2+2+2} = x^{8}[/tex]
Hence, Option (D) is correct
The exponent equation correctly shows that [tex](x^{2} )^{4}=x^{8}[/tex] is
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] = [tex]x[/tex] × [tex]x[/tex] ×[tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] = [tex]x^{8}[/tex]

In a study conducted at a large long-term care facility, two data collectors examined 56 pressure ulcers on 40 different subjects. The examinations were independently performed on the same day. A comparison of the results indicated that the data collectors scored 54 of the 56 (correlation coefficient 0.96) pressure ulcers identically using the Braden Scale for pressure ulcer assessment. What can be determined from this finding?
Answer:
Interrater reliability between the two data collectors was high
Step-by-step explanation:
Explanation-
Interrater reliability is the consistency of observations between two or more observers. An Agreement of 54 out of 56 scores would indicate a high level of interrater reliability. The data collection method was appropriate for pressure ulcer risk assessment. The risk assessments did not have to be done by both evaluators at the same time.what is 300 x 10 to the power of 5 in proper standard form?

Answer: Option A: The entire expression is a sum.
Option C: The term is a quotient are true statements.
Step-by-step explanation:
Determine which statements are true:
Option A: The entire expression is a sum.
All of the given terms are additions. Thus, it is true not false.
Option B: The coefficient of s is 3.
False ,s has no denominator 3 in it. In the equation for s, the coefficient is .
Option C: The term is a quotient.
The dividend is 7, the divisor is r, and the quotient is 7. So, It's true.

The distributive property applies.
(f·g)(x) = f(x)·g(x) = (3x +1)(x^2 -6) = 3x(x^2 -6) +1(x^2 -6)

Answer:
? = A) 4
Step-by-step explanation:
If we notice line FG and QR are similar.
FG = 24 and QR = 8. The relationship between the the two sides is that FG is 3 times more than QR ---> 8 x 3 = 24.
This relationship is true for the rest of the triangles since they are stated to be similar:
FG = 3(QR)
24 = 3(8)
EG = 3(6)
18 = 3(6)
Finding PQ:
EF = 3(PQ)
12 = 3(?)
? = 4
Therefore, the unknown side is 4.

What is the solution, if any, to the inequality 13x|20?
A.all real numbers
B.no solution
C.0x20
D.0x<0
Answer:
The solution of the inequality is [tex]x < \frac{20}{13}[/tex]
Step-by-step explanation:
We are given the following inequality:
[tex]13x < 20[/tex]
An inequality is solved similarly to an equality, isolating the desired variable. So
[tex]13x < 20[/tex]
[tex]x < \frac{20}{13}[/tex]
The solution of the inequality is [tex]x < \frac{20}{13}[/tex]
Three times one number added to five times another number is 54. The second number is two less than the first. Use a system of equations to find the numbers
Answer:
8 and 6
Step-by-step explanation:
If you use x for the first number, and y for the second, you get equations of 3x+5y=54 and x-2=y.
You can substitute the second equation into the first one to solve it. This gives 3x+5(x-2)=54.
The brackets can be expanded to 3x+5x-10=54. Collecting like terms makes it 8x-10=54.
Next, we add 10 to both sides. This gives 8x=64.
From there, we isolate the x by dividing both sides by 8, giving x=8.
To work out the second number, we can sub 8 for x in either equation (I'm using the second one as it's simpler).
This comes to y=8-2, therefore y=6.

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year. Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. Which system of equations can be used to find s, the number of pages in each issue of the sports magazine, and t, the number of pages in each issue of the technology magazine?
A. t = s - 18
10t = 12s + 32
B. s = t - 18
12s = 10t + 32
C. s = t - 18
10s = 12t + 32
D. t = s - 18
12t = 10s + 32
Answer:
[tex]\text{B .}\\\begin{cases}s=t-18, \\12s=10t+32\end{cases}[/tex]
Step-by-step explanation:
The each issue of the sports magazine, [tex]s[/tex], has 18 fewer pages than each issue of the technology magazine, [tex]t[/tex], we have equation [tex]s=t-18[/tex]. This eliminates answer choices A and D.
The second equation can be written from the fact that the total number of pages in all the sports magazines, [tex]12s[/tex], is 32 more than the total number of pages in all the technology magazines, [tex]10t[/tex]. Thus, we have equation [tex]12s=10t+32[/tex], eliminating answer choice C and leaving answer choice [tex]\boxed{\text{B .}\\\begin{cases}s=t-18, \\12s=10t+32\end{cases}}[/tex]
