Answer:
There would be a 56% increase
Step-by-step explanation:
We need to find the amount of change before we can find the percent of change. We'll take the greater value, 78, and subtract the lesser value, 50. 78 - 50 = 28. We then take this amount of change and put it over the original amount, Percent of change = Amount of change/ original amount or for this problem, 28/50. We then use that as a division equation for 28 divided by 50. 28 divided by 50 = 0.56. Finally we move the decimal to the right two times and we can then find the percentage increase.
Answer:
omg were u taking a test lol
Step-by-step explanation:
The data is already sorted for us. The median of this set is the middle most value which is 7 (in slot 4; three values to the left and three values to the right).
So the median is originally 7
If we add 5 to each data value we get
3+5 = 8
4+5 = 9
6+5 = 11
7+5 = 12
9+5 = 14
9+5 = 14
11+5 = 16
So the old data set
{3,4,6,7,9,9,11}
shifts to
{8,9,11,12,14,14,16}
after we add 5 to each value
The middle most value of the updated set is 12. It corresponds exactly to the old median of 7.
So we technically didn't even need to add 5 to all of the values to see what the new median would be. We simply need to add 5 to the old median to get the new median
I.e,
(new median) = (old median) + 5
Student B:
1/2 / 4
= 1/2 x 1/4
= 1/8
student A:
2/3 / 6
= 2/3 x 1/6
= 1/9
student C:
4/5/ 8
= 4/5 x 1/8
= 1/10
answer
student B: 1/8 of a mile per minute
student A: 1/9 of a mile per minute
student C: 1/10 of a mile per minute
Answer:
We conclude that is the binomial distribution.
Step-by-step explanation:
We know that the binomial distribution describes the probability of k successes in n draws with replacement.
We know that: Spinning an American roulette wheel 45 times and recording the number of times the ball lands on green.
So with each new turn, we have the same opportunity for the ball to be on the green.
We conclude that is the binomial distribution.
