A physician is testing the effectiveness of wo new exercise plans on 70 subjects. To assign the subjects to the two treatment groups, he writes "Plan 1" on one stip of paper and "Plan 2" on another slip of paper. He randomly picks one of the slips, and assigns the first 35 subjects who signed up to that plan, and assigns the last 35 subjects to the other plan. Select the statement that best describes the composition of the treatment groups.
The treatment groups might not be comparable, because there is not a control group
The treatment groups should be comparable, because there are a large number of subjects in each group.
The treatment groups should be comparable, because the exercise plan for each group was randomly selected
The treatment groups might not be comparable, because the first 35 subjects to sign up for the study might share a characteristic related to exercise, such as high motivation.

Which of the following is a binomial with degree 2?
A: 2+5x-3x^3
B: 2xy^2
C: 2x^3+xy
D: 3x+3x^2
Answer:
D
Step-by-step explanation:
Binomial means that it will have two terms, so by process of elemination, we are only left with C and D. Degree would be the power, and D is the only one that has a power of 2.

Answer:
x = 5.
y = -2
Step-by-step explanation:
y = x - 7
2x + y = 8
substitute the first equation into the second
2x + (x -7) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 8 + 7
3x/3 = 15/3
x = 5.
substitute 5 in the second equation
y = 5 - 7
y = -2
Please help! Slope intercept form
Answer:
3x + 5
Step-by-step explanation:
plug in (1,8) as x in y so it looks like this
8 = 3(1) + B then solve for B to get 5 then plug it in as y=3x+5

Franklin needs 1.25 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 25 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of the same dimension can he wrap using the spool of ribbon?
Answer:
6
Step-by-step explanation:
convert 1.25 meters to feet
1 meter = 3 feet
1.25 meters = 1.25 x 3 = 3.75 feet
Number of gifts he can warp = 25 feet / 3.75 = 6.6
Find the perimeter of A ABC. If necessary, round to the nearest tenth.
Answer:
37.6
Step-by-step explanation:
A to B - just count up the numbers, it's 10
B to C - just count up the numbers, it's 12
A to C - Now this is a right triangle, so use the Pythagorean theorem(10^2 + 12^2 = 244, and take the square root of that, which is 15.62 and round to 15.6
And just add them together 10+12+15.6 to get 37.6

George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.
Complete question − How many kilometres did they travel by bus and by bicycle.
Answer:George and carmen traveled by bus in 135km and by bikein 215km
Step-by-step explanation:
Total Miles traveled = 350 miles
Let Number of kilometres they traveled with bus = x
and Let Number of kilometres they traveled with bike = x + 80
so that the total distance traveled with bus and bike be expressed as
x + x + 80 = 350 miles
2x + 80 = 350 miles
2x = 350 − 80
2x =270
x=135
George and Carmen traveled by bus in 135km
and by bicycle=x + 80 = 135 km + 80 =215km
What is the solution to this system? Solve by substitution. y= 4x +3 and 2x - 3y = 21
Answer:
x= -3
y= -9
Step-by-step explanation:
Y-4X =3 ; 2x-3y=21
Y= 3+ 4x
2x -3( 3+4x)= 21
2x- 9- 12x= 21
-10x -9= 21
-10x -9+9= 21+9
-10x = 30
X= 30/-10= -3
Y= 3+4x = 3+ 4* (-3)= 3-12= -9
Gina is comparing the membership fees for two museums. The art museum charges a one-time fee of $7.25 plus $3.50 per month. - The science museum charges a one-time fee of $10.50 plus $4.50 per month. How much does she save after m months by joining the art museum instead of the science museum? (Hint: write the expressions for the art museum and the science museum FIRST and then find the difference)
Answer:
here two links for your answer. https://quizlet.com/325167814/financial-math-flash-cards/ https://quizlet.com/475135130/financial-math-e2020-flash-cards $2.5
Step-by-step explanation:
The art museum charges a one-time fee of $8.25 plus $2.25 per month.
So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)
Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.
Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)
So, from both the equations it is clear that for only joining the monthly charges are zero.
So, f(0) = 8.25 and g(0) = 10.75.
Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)

The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64
and a standard deviation of 4. What percent of bags of cookies will contain between 60
and 68 cookies?
Answer:
68% i think yeah?
The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.
What is standard deviation?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
[tex]\mu[/tex]= 64, [tex]\sigma[/tex]= 4,
[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]
= 60-64/4
= -1
again,
[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]
= 68-64/4
= 1
Thus, P( 60<X<68)
= p(-1<Z<1)
= 0.6829
= 68.29%

Becky is working on a weekly budget. She earns $385 per week. Becky spends $200 per week on rent and utilities plus $57 on food. After paying for rent, utilities, and food, Becky deposits 3/4 of the amount left over into a savings account. She spends the rest on entertainment. How much money does she spend on entertainment?
Answer:
$32
Step-by-step explanation:
200 + 57 = 257.
385 - 257 = 128
128 x 3/4 = 96 (deposited)
128 - 96 = 32
Becky spends $32 on entertainment
32 is what percent of 110? (round to the nearest percent)

Answer:
any coordinate outside the parabola is a reasonable answer.
Step-by-step explanation:
test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.
x = 0
y = 0
(0)^2 - 2(0) - 3 = -3
-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.
