Answer:
9 minutes
Step-by-step explanation:
In terms of hours, the travel times are ...
time = distance/speed
<u>Expected time</u>
te = (30 mi)/(50 mi/h) = 3/5 h = 36 minutes
<u>Actual time</u>
ta = (30 mi)/(40 mi/h) = 3/4 h = 45 minutes
Then the extra time taken is ...
(45 -36) min = 9 minutes
The journey took 9 minutes longer than expected.
The answer is 100/11 to ur question
Median
Median is the mean of 18 and 32 because they are in the middle, so it's 25. Median is the best representation because most numbers are around 20-30. 115 makes the mean go super high, which is not good, 11 drags the mean down, which is not good either.
Extras:
Mean: 11+11+18+32+34+115 =
221 divided by 6 =
36.88
Answer:
The answer you put is correct.
Step-by-step explanation:
It is B.
Given
centre of circle O(3,2)=O(x0,y0)
point on circle P(6,-2)
Standard equation of circle:
(x-x0)^2+(y-y0)^2=r^2
r=radius of circle
= (distance OP)
= sqrt((6-3)^2+(-2-2)^2)
=sqrt(3^2+(-4)^2)
=sqrt(25)
=>
r^2=(sqrt(25))^2=25
Equation of circle
(x-x0)^2+(y-y0)^2=r^2
(x-3)^2+(y-2)^2=25 ............... standard equation of circle
