Answer:x= 10
Step-by-step explanation:
40% of 50 is 20. So, 20/50 students who take the random sample prefer chocolate over vanilla ice cream. In order to find the number of students who prefer chocolate over vanilla ice cream out of 200 students in total, it is best to set up a proportion. Here: 20/50=x/200. Once you solve the proportion you will get x as 80.
Hope the explanation helped!
Answer:
C. The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.
Step-by-step explanation:
If t=3 or t=6 take the 3 and replace it for t. d(3)= 4.9(3)^2= 44.1 so with that answered you can now narrow the answer down to A. and C. so if we go back to the question the coin was dropped from the top of a building that then narrows it down to C.
40%=4/10=4*(1/10)
60%=6/10=6*(1/10)
-----------------------------
1/10 of 300 is 30, therefore 4/10 of 300 is 120.
-------------------------------
1/10 of 300 is 30, therefore 6/10 of 300 is 180.
-----------------------------
So, 120 students voted for Jennifer and 180 students voted for Kevin therefore, Kevin received 60 more votes.
