Answer:
8.7, 8.9, 9.0
Step-by-step explanation:
Answer:
8.7, 8.9, & 9.1
Step-by-step explanation:
The decimal places go up by tens like all other numbers. Therefore, 8.7, 8.9, and 9.1 are all in between 8.6 and 9.2
Suppose a force of 100 newtons is used to push an object a distance of 5.0 meters in 15 seconds. Find the work done and the power for this situation.
work=force* distance
=100*5

Which ordered pair would represent a ratio that is equivalent to those shown?
O 16, 12)
(9,6)
(8, 12)
O (12,8)
Answer:
Answer: (8,12) Third option
Step-by-step explanation:
Equivalent Ratios
Nardia plotted some points showing equivalent ratios. The points shown in the graph are: (2,3), (4,6), (10,15)
The ratios of the points in the form y:x are:
[tex]\frac{3}{2}[/tex]
[tex]\frac{6}{4}=\frac{3}{2}[/tex]
[tex]\frac{15}{10}=\frac{3}{2}[/tex]
Note all the ratios are equivalent.
From the ordered pairs provided in the choices, only one of them has the same ratio y:x.
Point (12,8) has a ratio:
[tex]\frac{12}{8}=\frac{3}{2}[/tex]
Answer: (8,12) Third option

Given the following data set: 3 5 6 7 7 8 8 8 9 9 9 10 102 Researcher detected the technical error in the last observation and replaced 102 by 10.2. What happens to Interquartile Range (IQR) and Standard Deviation (SD)
Answer:
After correcting the error, IQR remains unchanged while standard deviation reduced drastically from 26.3 to 2.04
Step-by-step explanation:
Given the data:
3 5 6 7 7 8 8 8 9 9 9 10 102
Ordered data: 3, 5, 6, 7, 7, 8, 8, 8, 9, 9, 9, 10, 102
The interquartile range (IQR) for the data:
IQR = Q3 - Q1
Q3 = 3/4(n + 1) th term.
n = sample size = 13
Q3 = 3/4(14) = 10.5th term
Q3 = (10 + 11)th term / 2 = (9+9)/2 = 9
Q1 = 1/4(14) = 3.5th term
Q3 = (3 + 4)th term / 2 = (6+7)/2 = 6.5
IQR = Q3 - Q1 = 9 - 6.5 = 2.5
THE STANDARD DEVIATION :
Sqrt[Σ(X - m)²/n-1]
Using calculator :
Standard deviation = 26.3
Correcting error in the data:
3 5 6 7 7 8 8 8 9 9 9 10 10.2
Q3 = 3/4(n + 1) th term.
n = sample size = 13
Q3 = 3/4(14) = 10.5th term
Q3 = (10 + 11)th term / 2 = (9+9)/2 = 9
Q1 = 1/4(14) = 3.5th term
Q3 = (3 + 4)th term / 2 = (6+7)/2 = 6.5
IQR = Q3 - Q1 = 9 - 6.5 = 2.5
THE STANDARD DEVIATION :
Sqrt[Σ(X - m)²/n-1]
Using calculator :
Standard deviation = 2.04
After correcting the error, IQR remains unchanged while standard deviation reduced drastically from 26.3 to 2.04
What is the slope of a line perpendicular to the line whose equation is x + 2y =8.
Fully reduce your answer.
Answer:
2
Step-by-step explanation:
First, put the line into y = mx + b form to find the slope (m)
x + 2y = 8
Subtract x from both sides
2y = -x + 8
Divide each side by 2
y = -1/2x + 4
So, the slope of this line is -1/2
Perpendicular lines have a opposite reciprocal slope, so the slope of a perpendicular line will be 2.

Combine like terms in expression below
2f + 9e - f + 3e
Answer:
12e + f
Step-by-step explanation:
2f - f = f
9e + 3e = 12
....
Answer:
f + 12e
Step-by-step explanation
(+2f) + (+9e) + (-f) + (+3e)
(2f) + (-f) = 1f or f
9e + 3e = 12e
f + 12e

Answer:
[tex]x=2[/tex]
Step-by-step explanation:
We are given:
[tex]\displaystyle \frac{w^{-x+4}}{w^{-3}}=w^{2x+1}[/tex]
First, by the quotient property:
[tex]w^{(-x+4)-(-3)}=w^{2x+1}[/tex]
Since they both have the same base, their exponents must be equivalent:
[tex](-x+4)-(-3)=2x+1[/tex]
Solve for x. Simplify:
[tex]-x+7=2x+1[/tex]
Therefore:
[tex]3x=6\Rightarrow x=2[/tex]
Answer:
x=2

In the first week of August, there were 1,060 people at an amusement park. In the second week, there was a 20% decrease in attendance. The park had estimated that 1,500 people would attend the 2nd week. What is the approximate percent error of their estimate?
Answer:
solution
1060/100=10.6
20x10.6=212
1060-212=848
1500-848=652
(652/848)x100=76.886%
Find c. Round to the nearest tenth. Laws of sines
9514 1404 393
Answer:
c ≈ 56.3 cm
Step-by-step explanation:
I find it convenient to turn the given equations upside down. Then you just need to multiply by sin(C) to get the solution.
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (27 cm)sin(102°)/sin(28°)
c ≈ (27 cm)(0.978/0.469)
c ≈ 56.3 cm

Which equation and solution can be used to solve this problem?
Twenty-two less than a number is twenty-four.
q + 22 = 24: Subtract 22 from both sides. The answer is 2.
24 + q = 22: Subtract 22 from both sides. The answer is 2.
q minus 24 = 22: Add 24 to both sides. The answer is 46.
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Answer:
Step-by-step explanation:
22 less than a number, q-22, ‘is’ 24 is =24
q-22=24 adding 22 to both sides gives q=46
Answer:
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Step-by-step explanation:
Solve each equation to see if it works.
Q - 22 = 24 does work.

Step-by-step explanation:
Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to 1. response bias. 2. instrumentation bias. 3. researcher bias. 4. sampling bias.
Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.
