To find the midpoint you find the average x and the average y values. The average of 1 and 9 is 5, and the average of 4 and 16 is 10. The midpoint would be (5,10).
Answer:
20hours
Step-by-step explanation:
Jack can complete the painting in 30hours. The fraction he can paint per hour is thus 1/30
Trainee can complete the painting in 45hours, the fraction he can paint per hour is 1/45
If they are working together, the fraction that can paint in an hour is :
1/45 + 1/30 = 5/90 = 1/18
Now we know they can paint 1/18 of the room in an hour, the number of hours needed to completely paint the room is thus 1/1/18 = 18 hours
Rounding up answer to the nearest tenth is 20hours
Two sample hypothesis testing assumes that the samples are; <u>A: Independent samples.</u>
<h3>How to interpret two sample hypothesis?</h3>
In two sample hypothesis testing, we can say that there are few assumptions that must be considered before being confident that the right test was applied to the given data. Thus, In a two sample hypothesis testing, it is pertinent to note that the two sample are assumed to be independent to each other.
Now, the two sample hypothesis testing is also said to be aimed at testing and comparing samples that are not even related. Therefore, if the two samples are dependent on each other, then the two samples definitely came from the very same population.
Thus, the correct answer among the choice is option A.

Answer:
B) 4/10 and 3/10
Step-by-step explanation:
2/5 x 2/2 = 4/10 They both no have the same denominator now
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
