Answer:
The underlying probability distribution can't be determined with certainty in this case from the given data, but if we have to take one it would be most preferably the 'Normal Distribution'.
Step-by-step explanation:
The distribution is most probably 'Normal Distribution' as we know that it is the most general and common distribution of all and from the central limit theorem if there is a large sample from any probability distribution with finite mean and variance, the sample mean approaches a suitable normal distribution and for most of the distributions when the parameters tend to a certain value or may be that is ∞ , the resulting distribution tends to a suitable normal distribution , but the underlying probability distribution can't be determined with certainty in this case from the given data.
Answer:
Dennis skated 35/4 of track in two minutes.
35/4 = 8 3/4
Step-by-step explanation:
Given that;
Daniel skated 2 1/2 of the way around the track in two minutes
Daniel = 2 1/2 = 5/2 of track
her younger brother skated 3 1/2 of Daniels distance in two minutes
Dennis = 3 1/2 of Daniel's = 3 1/2 of 5/2
Dennis = 3 1/2 × 5/2 = 7/2 × 5/2
Dennis = 35/4 = 8 3/4
Therefore, Dennis skated 35/4 of track in two minutes.
Currently 100 students can eat for 20 days, so we need to find the number of days 125 students can eat.
Originally:
100 students eat for 20 days
New:
125 students eat for x days. Multiply original number of students by original number of days which will give the total amount of students per day. Then divide the total amount of students per day by the new number of students to find the new number of days.
x= (100 students * 20 days)/ (100+25)
x= (100 * 20)/ 125
x= 2000/125
x= 16 days
ANSWER: 125 students can eat for 16 days.
Hope this helps! :)
7(3r-1)-(r+5)=-52
21r-7-r-5=-52
21r-r-5-7=-52
20r-12=-52
Add 12 to both sides
20r=-40
Divide by 20
r=-2
Use the formula y2-y1/x2-x1
-3 - 0/ 4 - 16 = -3/-12 = 1/4
so the slope is 1/4
