#7 is B, the trapezoid is reflected across the x axis
#8 is C, unlike D, answer C is still the same shape as triangle A. Answer A is just the same triangle in the same position, can't tell if it moved or not bc it never showed us. B is a reflection, it's flipped.
#9 is D, nothing has changed except it's position; it's been moved to the right
#10 is C, the points of the triangle are at different positions, and it didn't look like it flipped over the x or y axis, so it's reflection. It's also moved to the right, so translation

1. Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting seashells. Marisol started with zero seashells in her collection. Pilar adds 10 seashells to her collection each week for x weeks. • Marisol adds 20 seashells to her collection each week for x weeks.
(a) Write an inequality to represent the situation when the number of seashells in Marisol's collection is greater than the number of seashells in Pilar's collection
(b) Solve the inequality in part (a) for the x. Show your work and explain your answer.
Answers
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Answer:
Pilar started with 80 and adds 10 each week.
y= 10x + 80 (ten seashells • weeks + 80 she started with)
Marisol started with 0 and adds 20 each week.
y = 20x (no need to add + 0 because she started with nothing)
Inequality:
y = 10x + 80 < y = 20x

3. A certain academic department at a local university will conduct a research project. The department will need to hire graduate research assistants and professional researchers. Each graduate research assistant will need to work 23 hours per week on fieldwork and 17 hours per week at the university's research center. Each professional researcher will need to work 15 hours per week on fieldwork and 25 hours per week at the university's research center. The minimum number of hours needed per week for fieldwork is 154 and the minimum number of hours needed per week at the research center is 140.

Step-by-step explanation:
1) Energize pills cost 40 cents each, while Excel pills cost 100 cents each. If x represent the energize pills and y represent the excel pills, the objective function would be:
minimize cost = cost of energize pill + cost of excel pill
Minimize cost = 40x + 100y
2) Let x = the number of mountain bikes they produce, and let y = the number of racing bikes they produce.
7 hours of assemble time to produce a mountain bike and 8 hours of assemble time to produce a racing bike. Since the company has at most 190 hours for assemble time, it can be represented as:
7x + 8y≤ 190
5 hours of mechanical tuning to produce a mountain bike and 4 hours of mechanical tuning to produce a racing bike. Since the company has at most 22 hours for mechanical tuning, it can be represented as:
5x + 4y ≤ 22
Also assemble time and mechanical time must be greater than 0, hence:
x ≥ 0, y ≥ 0
3) The fieldwork constraint can be represented as:
23x + 15y ≥ 154
The time to be spent at university research center can be represented as:
17x + 25y ≥ 140
Both fieldwork time and time spent at university research center mut be greater than 0, hence:
x ≥ 0, y≥ 0
The cost equation is:
Minimize cost = 295x + 416y

Answers
Answer:
The correct selections are:
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Step-by-step explanation:
What this question requires from you, is to identify the correct characteristics of the study described. Let us explain why each of the selections was made.
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups: The purpose of the study is to determine the difference in the effectiveness of two methods of fundraising. Therefore at the end of the study, the average total amount raised from each group will be compared to determine which was more effective.
C) A placebo is not being used: Placebos are sham treatments used in a control group without their knowledge. The placebos do not produce any effect similar to the results anticipated the actual treatment. Here, no group is given sham treatment, there is no "control" group given placebos hence placebos are not used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call: To remove any form of bias in the study, the selection of the groups is done at random, and the number of participants in each group is the same, so as to maintain uniformity during the comparison.
The right statement selection will be of these are:
A) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Use a random number generator to choose from a list of [tex]1000[/tex] past donors, half will be i.e.,[tex]=\frac{1000}{2} =500[/tex] will be sent literature, and the other 500 donors will be contacted by phone.
And the percentage of people from each group will be compared i.e. we make the total amount from each of the two treatment groups.
In this case, Placebo is not used.

A new version of the Medical College Admissions Test (MCAT) was introduced in spring 2015 and is intended to shift the focus from what applicants know to how well they can use what they know. One result of the change is that the scale on which the exam is graded was modified, with the total score of the four sections on the test ranging from 472 to 528. In spring 2015, the mean score was 500.0 with a standard deviation of 10.6.

b. 472 to 528.
c. 491.096 to 508.904.
d. 480 to 520.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Assume a normal distribution with:
Mean (m) = 500
Standard deviation (sd) = 10.6
A) The median of the MCAT scores :
For a normal distribution, the Median = mean = 50% = 0.5
Zscore at 0.5 = - 0.0
-0.0 = (x - m) / sd
-0.0 = (x - 500) / 10.6
0 = x - 500
x = 500
B) the first quartile (Q1) score = 25% = 0.25
Using :
Zscore at 25% = 0.25 = -0.675
Zscore = (X - m) / sd
-0.675 = (X - 500) / 10.6
-7.155 = x - 500
x = - 7.155 + 500
X = 492.845
C.) the third quartile (Q3) score = 75% = 0.75
Using :
Zscore at 75% = 0.25 = 0.675
Zscore = (X - m) / sd
0.675 = (X - 500) / 10.6
7.155 = x - 500
x = 7.155 + 500
X = 507.155
D.) The interquartile range :
Q3 - Q1
= 507.155 - 492. 845
= 14.31
2.) Interval which contains 80% of MCAT Scores:
Zscore of the (100-80)% / 2 at the extremes ; = 20%/2 = 0.1 ; 0.1 = - 1.28
Interval:
(-1.28 * sd) + mean and (1.28 * sd) + mean
(- 1.28 * 10.6) + 500 and (1.28 * 10.6) + 500
-13.568 + 500 and 13.568 + 500

Each desktop computer takes 10 hours of assembly time and 2 hours of quality control time. Each laptop computer takes 6 hours of assembly time and 7 hours of quality control time. The company has a maximum of 2,800 assembly hours and 1,000 quality control hours per week. In your answer, let x be the number of desktops to produce, and let y be the number of laptops to produce. Write the linear programming problem which must be solved to determine how many of each kind of computer should be made in order to maximize profit.
Answers
Answer:
248x+259y>=P (objective function)constraints10x+6y<=2800------12x+7y<=1000-------2To maximize profit(P>=$79,905)the company needs to produce 35 desktop computers and 275 laptops computersStep-by-step explanation:
let x be the number of desktops to produce, and
let y be the number of laptops to produce.
let the profit be p
maximize P (objective function)
248x+259y>=P
The products are subject to the constraints (that is, the restrictions)
1. Assembly hours
assembly time 10 hours and 6 hours for desktop and laptop respectively
maximum assembly hours is 2800
10x+6y<=2800------1
2. Quality control time
Quality control time 2 hours and 7 hours for desktop and laptop respectively
maximum assembly hours is 1000
2x+7y<=1000-------2
we can now solve equation 1 and 2 to get the values of x and y
10x+6y<=2800------1
2x+7y<=1000-------2
multiply equation 2 by 5 we have
10x+6y<=2800------1
10x+14y<5000-----3
subtract equation 3 from 1 we have
0x-8y<=-2200
8y<=2200
divide both sides by 8
y<=275
substitute y=275 in equation 1 we have
10x+6y<=2800------1
10x+6(275)<=2800------1
10x+1650<=2800
10x<=2800-1650
10x<=350
divide both sides by 10 we have
x<=35
we proceed by substituting x=35 and y=275 in the objective function we have
248x+259y>=P
248(35)+259(275)>=P
8680+71225>=P
P>=$79,905
Solve for p.
