Answer:
A. True
Step-by-step explanation:
A paired T- test is also sometimes called the dependent sample t-test. It may be defined as a statistical procedure that is mainly used to determine if the mean variance between the two samples or units of the observations are zero or not.
It helps to compare the two means which are taken from the same objects, related units or from same in individual.
According to the question, the answer is true as the paired T-test can be reduced to the single mean T- test.

Line Q is represented by the following equation: 2x + y = 11
Which equation completes the system that is satisfied by the solution (3, 5)? (4 points)
a
x + 2y = 15
b
x + y = 15
c
x + y = 8
d
x − y = 2
Answer:
C) x+y=8
Step-by-step explanation:
I enter (3,5) into 2x+y=11
2*(3) + 5 = 11
11=11 correct
You now you need to enter the (3,5) into all the equations and see if they are correct
A: x + 2y = 15
3+ 2*5=15
13 = 15 is not correct
B. X+ y = 15
3+5= 15
8=15 not correct
C.x + y=8
3+5=8
8=8 correct
D. X-y = 2
3-5=2
-2= 2 not correct
Answer:
The answer is C
Step-by-step explanation:
I know this because I took the test, I also responded so you can mark the other person brainliest

What is the LCD of 1/2 and 2/17
Answer:
34
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/2, 2/17
For the denominators (2, 17) the least common multiple (LCM) is 34.
LCM(2, 17)
Therefore, the least common denominator (LCD) is 34.
consider n proper fraction such that the numerator is 2 less than the denominator. If the numerator and denominator are each increased by 1, then the ratio of the numerator and denominator of the new fraction is 4:5. Determine the original fraction
the original fraction would be 4:5 divided by 2 and 1 making the answer clear and then what you do is take your answer multiplying it by the improper fraction and subtracting it by the mixed and the others that you should know and then you get your real answer.

How are corresponding side lengths of two similar figures related?
Answer:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Step-by-step explanation:
Answer:
If two objects have the same shape, they are similar. If they are similar, the ratios of side lengths are equal. If the base of a rectangle was 22 feet and it was dilated by 2, the base would be 44 feet. The angle measures however, stay the same, or the two figures would not be similar.

In the equation y = x +2, x represents Jean's age in years, and y represents the age of Jean's older sister, Rachel. Which is the graph of this equation? (please help)
Answer:
C.
Step-by-step explanation:
The equation is already in y = mx + b format. M means slope and b means is the y-intercept. Since we can see the slope is 1 and the y-intercept is 2, we can find the graph that matches this. In graph C, the line intercepts the y axis at the point 2 and the line goes up 1 on the y axis for every 1 on the x axis so it is true.

It is computed that when a basketball player shoots a free throw the odds in favor of his making our 23 to 3 find the probability that when does basketball player shoot a free throw he misses it out of every 100 free throws he attempts on the average how many should he make
Answer:
Step-by-step explanation:
So think like a percent 3 percent of 23 of mean multiply so first 23 divided by 100 equals what then to check the answer multiply it by 3
Using the probability concept, it is found that:
There is a 0.115 = 11.5% probability that he misses.Out of 100, on average, he would make 88.5.A probability is the number of desired outcomes divided by the number of total outcomes.
The odds in favor of his making is 23 to 3, which means that, for each free throw he takes:
The probability of making it is [tex]\frac{23}{23 + 3} = \frac{23}{26} = 0.885[/tex].The probability of missing it is [tex]\frac{3}{26} = 0.115[/tex].There is a 0.115 = 11.5% probability that he misses.
Out of 100, on average, he would make 0.885(100) = 88.5.

One of Camille’s graduation gifts is a trip on Amtrak from his home in Atlanta to New York to visit a cousin. Camille is afraid he may experience motion sickness so he has decided to take 50 mg of dimenhydrinate (which will help prevent motion sickness) before boarding Amtrak. Suppose that 85% of this medication remains in the bloodstream after 1 hour. Represent the amount of dimenhydrinate in Camille’s bloodstream for the first 4 hours of taking the drug. Let t be the number of hours after reaching its peak level of 50 mg. Explain how you determined the amount of dimenhydrinate in Camille’s bloodstream.
Answer:
26.10 mgStep-by-step explanation:
Initial amount of drug = 50 mgRemains after each hour = 85%Time = tThis relationship can be shown as a function:
y(t) = 50(0.85)^tAfter 4 hours remaining drug in blood:
y(4) = 50(0.85)^4 = 50(0.522) = 26.10 mg
