Answer:
0.46017
Step-by-step explanation:
Given :
Mean score = 75
Standard deviation, s = 10
Areum's score = 76
Probability of scoring higher than Areum is given by :
P(x > 76)
The standardized score : (x - mean) / standard deviation
P(x > 76) = P[Z > (76 - 75) / 10]
P[(Z > 0.1)] = 0.46017 (Z probability calculator)
= 0.46017
Answer:
6 minutes 8 balloon animals. 45 minutes 60 balloon animals!
Step-by-step explanation:
I divided 15 by 6 and got 2.5, so I then divided 20 by 2.5 and got 8 balloon animals! For the next one I divided 45 by 15 and got 3 then I multiplied 20 by 3 and got 60 balloon animals! Hope this helps!
Answer:
A
Step-by-step explanation:
SO right off the bat it cannot be c, for they do definatly change.
Next, lets find out how much they change by.
The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.
This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.
Now, the mean is already 500/4. This equals 125.
So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.
That is 500/5. This equals 100.
This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25
That is 5x more of a decrease than the mean.
SO it must be A, since the mean decreased more than the median.
Answer:
89
Step-by-step explanation:
100/36= 2.77777778
2.77777778·32 = 88.8888889
89
