Answer:19 students
Step-by-step explanation:
First you would add together all the students that you know take a math class. So you would add 14+20+7 to get 41 students. So now you know that that many students take a math class. So you would do 60-41 because 60 is your overall number of students. After you subtract them you should get 19 which is your answer-19 students don’t take either of the subjects
Since the Venus orbits round the sun, the sun is the center of the circular path of the revolution of the planet, Venus.
Thus, the distance of the planet, Venus fron the sun is given by the distance between the points (0, 0) and (41, 53).
Recall that the distance between two points
and
is given by
Thus, the distance between the points (0, 0) and (41, 53) is given by:
Given that each unit of the plane represents 1 million miles, therefore, the distance from the sun to the Venus is 67 million miles.
It’s B because C is too much and A is to little for the correct answer
You fill the 3 gallon jug up completely, then you pour that into the 5 gallon bucket. Then you fill up the 3 gallon jug again, and pour as much as you can into the 5 gallon bucket until it is full. You should then have 1 gallon of liquid left in the 3 gallon jug, and the 5 gallon bucket would be full. I hope that makes sense!
Answer:
(a) 3, 5 and 6
Step-by-step explanation:
In the experiment, 43 are to be given a gel that contains the tooth-whitening chemicals while the remaining 42 are to be given a placebo. Therefore, a placebo is used.
The 43 that will receive the gel are to be selected randomly.
After the experiment, the whiteness of the two groups will be compared to see the effect of the gel.
Therefore for the experiment to be completely random, 3, 5, and 6 apply.
(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
