Step-by-step explanation:
Use (a - b) (a + b) = a^2 -b^2 to simplify the product.
[tex](2x)^{2} - (7y)^{2} [/tex]
To raise the product to a power, raise each factor to that power:

Participants enter a research study with unique characteristics that produce different scores from one person to another. For an independent-measures study, these individual differences can cause problems. How can these problems be eliminated or reduced with a repeated-measures study? Check all that apply. In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions. In a repeated-measures study, you eliminate extraneous changes to the individuals in the sample over time. In a repeated-measures study, both samples consist of the same individuals, eliminating systematic differences between the two samples, which bias the results. In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.

• In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
Step-by-step explanation:
An independent measures design, is an experimental design whereby the condition of the experiment is such that there are different group of participants. Based on the information given, the problems can be eliminated or reduced with a repeated-measures study through:
• In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions
• In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
Therefore, the correct options are A and D.
A committee consisting of 5-studnts is to be formed out of 10, of which 4-are females and 6-are males. How many committees can be formed if 3 males are to be included
Answers
Answer:
120 committees can be formed if 3 males are to be included
Step-by-step explanation:
Total members in the committee = 5
Out of 10 people, 6 are males and 4 are females
In committee of 5 people, 3 males are to be chosen out of 6 and 2 females are to be choses out of 4
Total number of outcomes = 4C2 * 6C3
Total number of outcomes = 6 * 20 = 120

Choice C: Lauren is faster than Kevin, slower than Jeremy.
Step-by-step explanation:
Ok, so it directly says that Jeremy is going at y=12x, or 12 miles per hour. To find how fast Kevin is riding, take two points of the table and use the slope formula to get the speed(.
Slope Formula: (y2-y1) / (x2-x1)
So lets take the table plots (2, 22) and (4, 33) to do this.
(y2-y1) / (x2-x1)
(33-22) / (4-2)
(11) / (2)
The speed of Kevin is 5.5 miles by hour.
Then, it asks for how fast Lauren is going, saying she is twice as fast as Kevin. Therefore, simply do:
5.5 * 2 = 11 miles per hour
To get the third biker's speed.
Now, with all of the speeds of the bikers, we can now compare them. Here's a listing of their speeds to make things easier to compare:
Jeremy: 12 mph
Kevin: 5.5 mph
Lauren: 11 mph
From this, we can see that Lauren is the second fastest. She is slower than Jeremy but faster than Kevin. Therefore, the correct answer choice is C.
A person playing a game of chance has a 0.20 probability of winning. If that person plays the game 20 times and wins half of that number of times, what is the difference between the theoretical probability and the experimental probability of that person winning?
Answers
Answer:
Step-by-step explanation:
The theoretical result is 0.2 * 20 = 4
The experimental result is 1/2 * 20 = 10
The difference is 10 - 4 = 6
The probability difference = 6/20 = 0.3

A farmer sells 7.5 kilograms of apples and pears at the farmer's market. 3/4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answers
Answer: 1.87 kg of pears
Step-by-step explanation:
7.5 kg of both apples and pears were sold. 3/4 of this 7.5 kg is apples which means the amount of apples sold is:
= 7.5 * 3/4
= 5.63 kg of apples
The amount of pears sold would therefore be:
= Total amount sold - Amount of apples
= 7.5 - 5.63
= 1.87 kg of pears

A yield sign is an equilateral triangle with a side length of 36 inches. What is the height (h) of the sign? Leave your answer in simplest radical form.
Answers
Answer:
18[tex]\sqrt{3}[/tex] inches
Step-by-step explanation:
Applying,
Pythagoras theorem,
a²= b²+c²
Where a = hypotenus, b = base of the triangle, c = height.
make c the subject of the equation
c = √(a²-b²)................. Equation 2
From the diagram attached,
Given: a = 36 in, b = (36/2) in = 18 in
Substitute these values into equation 2
c = √(36²-18²)
c = √(1296-324)
c = √(972)
c = √(972)
c = √(324×3)
c = 18[tex]\sqrt{3}[/tex] inches

Please help, nobody is helping I need to find surface area
Answers
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same
[tex]A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20[/tex]
This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6

What value of x would prove a || b (a parallel to b)? (Hint: Add consecutive interior angles to solve for x).
Answers
Answer:
x=8
Step-by-step explanation:
19x-13+6x-7=180
x=8
We have a || b (a parallel to b), the interior angle property. Therefore, the value of x would be 8.
What is the sum of interior angles of parallel lines?The sum of all the interior angles of parallel lines is equal to 180 degrees.
We have a || b (a parallel to b), the interior angle property
19x - 13 + 6x - 7 = 180
25x - 20 = 180
25x= 200
x = 8
Therefore, the value of x would be 8.
