A local employer asked for help selecting a new type of desk chair. Thirty employees volunteered, and each employee used the new desk chair for two weeks and the current desk chair for two weeks. To determine which chair was used first, a coin was flipped for each employee. Heads represented using the new chair first, and tails represented using the current chair first. At the end of each two-week period, the employees were asked to rate their satisfaction with the new chair. Which of the following best describes this study?
Answer:
E-It is a well-designed experiment because there is random assignment, replication, and comparison of at least two treatment groups.
Random assignment, replication, and the ability to compare at least two treatment groups are all criteria for a well-designed experiment.

On the graph, two right triangles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope
between points E and A is the same as the slope between points A and C.
Part A
Which angles of the triangles measure 90°?
Part B
To show that the other two angle measurements in each triangle are equal, you can use parallel lines cut by a transversal.
Which two pairs of line segments formed by triangle sides are parallel, and what is the transversal for each pair?
Part C
Which angle has the same measurement as angle DEA, and how do you know that the measurement is the same?
Part D
Which angle has the same measurement as angle DAE and why (vertical, corresponding, alternate interior, or alternate exterior
angles)?
Part E
Are the two triangles congruent? Why or why not?
Part F
Are the two triangles similar? Why or why not?
Part G
Write a fraction setting the vertical length of the larger triangle over its horizontal length. What does this fraction represent?
Part H
Write a fraction setting the vertical length of the smaller triangle over its horizontal length. What does this fraction represent?
Part I
To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true? Why or
why not? What does that mean about the slope between points E and A and the slope between the points A and C?
Answer:
a: b,a,d
b:6,8
c:Angles in a triangle add up to 180:
Angles in ΔDAE=Angles in ΔABC
∠DAE+∠EDA+∠DEA=∠BCA+∠ABC+∠BAC
∠EDA+∠DEA=∠ABC+∠BAC (since ∠DAE=∠BCA, we can cancel them out)
∠DEA=∠BAC (∠EDA=∠ABC=90)
e:BCA because they are corresponding angles.

What are the x-intercepts for the graph of y=3(x-1)(x+6)?
Answer:
Step-by-step explanation:
As always, set the function equal to zero and solve for x:
x - 1 = 0 results in x = 1. Thus, (1, 0) is one of the x-intercepts.
x + 6 = 0 results in x = -6. (-6, 0) is the other x-intercept.

How can I find the area of this figure?
Answer:
Area = y² + 2x + 1
Step-by-step explanation:
You have to combine like terms:
The little square is 1 unit, so 1
The two bars are each worth x, so 2 * x = 2x
The big square is y²
The total area is the sum of all terms:
Area = y² + 2x + 1

Decomposition, find f(x) and g(x) so that the function can be
described as y = f(g(x))
y = (x – 4) + 5
f(x)=
g(x) =
Answer:
steps below
Step-by-step explanation:
f(x) = x + 5
g(x) = x - 4
f(g(x)) = f(x-4) = (x-4) + 5
5 out of 6 students baseball is their favorite sport what is the decimal equivalent for the number of students who choose baseball .
Answer:
5/6 (if using calculator enter answer) =0.833
or 5÷6 = 0.833
Step-by-step explanation:
since 5 out of the 6 people chose baseball you put 5 (the chosen) over 6(the total number) and then you change the fractional into a decimal by dividing
Mahni plans to spend the next 12 weeks saving some of her income. She will save $x a week for the first 6 weeks and then $(2x − 30) a week for the following 6 weeks. If she managed to save $213 in the first six weeks, how much did she save in total over 12 weeks? Explain correctly how to do this to get Brainliest ANSWER
For first six weeks she saved 213$
Now
For next 6weeks
[tex]\\ \sf\longmapsto 2x-30=2(213)-30=426-30=396\$[/tex]
Total savings:-
.[tex]\\ \sf\longmapsto 396+213=609\$[/tex]
Answer:
$459Step-by-step explanation:
Mahni saved 6x in the first 6 weeks which is $213.
She saves in the next 6 weeks:
6*(2x - 30) = 12x - 180 = 2*6x - 180 = 2*213 - 180 = 246Total saving is:
213 + 246 = 459Write the inequality shown by the graph.

2. Stephen Curry's record during the 2017 – 2018 NBA final game is made up of 2-point shots and 3-points.
His total points scored for the final game was 45 points with 19 shots made. How many 2-point shots did
he make? How many 3-point shots did he make?
Answer:
He made 7 3-point shots.
Step-by-step explanation:
x+y=19
2x+3y=45
y=19-x
2x+3*(19-x)=45
2x+57-3x=45
-x=45-57
-x=-12
x=12
y=19-12
y =7
