Answer:
x= 50°
w= 130°
y°= 110°
z°=30°
Step-by-step explanation:
x°= 180° - 60°- 70° ( angle sum of triangle)
= 50°
w°= 180° - 50° ( adjacent angles on a straight line)
= 130°
y°= 180° - 70° ( adjacent angles on a straight line)
= 110°
z°= 180 - 40° - 110° ( angle sum of triangle)
= 30°

You've developed a protein drink that you think cures arthritis. to test it, you find 200 volunteers (100 men and 100 women) and test them to measure the amount of discomfort they feel from their arthritis. then you give the treatment to half the subjects and a placebo to the others. you then test them all at regular intervals and measure their improvement. you find that the subjects who received the treatment show marked improvement. the people performing the tests are not told that they're studying an arthritis medication. you excitedly report your findings in an infomercial that is seen by millions of people, and sales skyrocket. but were the test results truly useful for determining the effectiveness of the treatment? why or why not? a. no, there was no control. b. yes, it's a blind-study. c. yes, it's a valid before-and-after design. d. can't be determined without knowing how much improvement was measured. e. no, there was no replication.
Answers
Answer:
I would say C
Step-by-step explanation:
In this experiment the subjects do not know whether they are being given the real treatment or a placebo. Also the testers do not know that treatment for arthritis has been given. The subjects being given the treatment "show marked improvement" according to the tests. Therefore this is a valid double blind experiment, making C the correct choice.

Sarah visits an amusement park with an admissions cost of $24. Each ride costs $3. She does not buy any food or drink while she is there. If y represents the total she spends at the park and she takes x rides, which of the following is a function that represents her total spending?
A. y=24x+3
B. x+y=27
C. y=3x+24
D. y=27x
Answers
Answer:
Option C. y=3x+24 is the correct answer
Step-by-step explanation:
Using the given information,
Number of rides = x
Total cost = y
Admission cost = $24
The admission cost is a one-time cost that will remain constant while each ride costs 3 dollar so for x rides the cost will be 3x.
The total cost, if she buys no food or drink will be: 24+3x
Now we know that total cost is equal to y then
y = 24+3x
OR
y = 3x+24
Hence,
Option C. y=3x+24 is the correct answer

300x + 300 x plus StartFraction 500 over 7 EndFraction left-parenthesis 87.5 right-parenthesis equals 10,000.y = 10000
Answers
Answer:
x = 12.5
Step-by-step explanation:
The correct question can be found in the attachment
300x + 500/7y = 10,000
Find x if y = 87.5
Substitute y = 87.5 into the equation
300x + 500/7(87.5) = 10,000
300x + 43,750/7 = 10,000
300x + 6,250 = 10,000
Subtract 6,250 from both sides
300x + 6,250 - 6,250 = 10,000 - 6,250
300x = 3,750
Divide both sides by 300
x = 3,750/300
= 12.5
x = 12.5 when y = 87.5

Karl is making a pot of chili. The recipe calls for 3/8 cup of chili powder, but Karl only wants to use half as much so it won’t be so spicy. How much chili powder should Karl use?
Answers
Answer:
KArl should use 3/16 cups of chili powder
Step-by-step explanation:
Given that:
Recipe's requirement : 3/8 cups
Karl wants to use half : 1/2
The given question involves fractions. When the number of cups has to be divided into half, it will be multiplied with 1/2.
So,
Multiplying the chili powder requirement of the recipe to 1/2
[tex]=\frac{3}{8} * \frac{1}{2}\\= \frac{3}{16}[/tex]
Hence,
KArl should use 3/16 cups of chili powder

A coffee distributor plans to mix some Rift Valley coffee that normally sells for $12.10 per pound with some Mexican Shade Grown coffee that normally sells for $13.10 per pound to create 50 pounds of a new coffee blend that can sell for $12.62 per pound. How many pounds of each kind of coffee should they mix? Answer: pounds of Rift Valley coffee? pounds of Mexican Shade Grown coffee? Round your answers to the nearest whole number of pounds.
Answers
Answer:
24 pounds of Rift Valley coffee
26 pounds of Mexican Shade Grown coffee
Step-by-step explanation:
If R is pounds of Rift Valley coffee, and M is pounds of Mexican Shade Grown coffee, then:
R + M = 50
12.10 R + 13.10 M = 12.62 (50)
Substitute:
12.10 R + 13.10 (50 − R) = 12.62 (50)
12.10 R + 655 − 13.10 R = 631
R = 24
M = 26
A teacher estimates there are about 600 students at their school. If there are actually 625 students, then what is the percent error of this estimate?
Answers
Answer:
4%
Step-by-step explanation:
(|600-625|)/625 x 100
=4%
Answer:
The percent error for this estimate was 4%.
Step-by-step explanation:
Teacher's estimated students = 600
Actual students = 625
625-600 = 25 students are more than the teacher's estimate.
In other words, the measurement error = 25 students
Now the percent error can be calculated by dividing 25 (measuring error) by the actual students.
Percent error = 25/625 = 0.04 which is 4%
Therefore, the percent error for this estimate was 4%.
