Well, if it was out of 50, it would be 76%.
So the answer might be 50 questions total, but maybe there was 49 questions total.
I would probably go with 50 questions total.
Answer:
534 is the mean.
Step-by-step explanation:
to calculate the mean you add all the numbers together (for example this set of numbers):
785, 585, 465, 409, 495, 465
=3204
then divide the number of numbers that you added together , (in this case 6)
3204/6
=
534
Answer:
The points are sqrt(164) or 2sqrt(41) units apart.
Explanation:
You didn't provide the options in your question. But to find the distance, you need to use the distance formula.
d=sqrt((y2-y1)^2 + (x2-x1)^2)
d is the distance, and (x1, y1) and (x2, y2) are the points.
Use point J (-4,-6) for (x1,y1) and point K (4,4) for (x2, y2).
d=sqrt((4-(-6))^2 + (4-(-4))^2)
=sqrt(10^2 + 8^2)
=sqrt(100+64)
=sqrt(164)=2sqrt(41)
You can compare this to the answer options and find the closest. Hope I could help! :)
The area of the field will be given by:
Area=[area of the semi circle]+[area of rectangle]
Area of semicircle is given by:
Area=πr^2
where;
radius,r=66/2=33 m
thus;
Area=3.14*33^2
3,419.46 m^2
The area of the rectangle is given by:
Area=89*66
=5,874 m^2
Hence the area of the field will be:
A=(5,874)+(3,419.46)
A=9,293.46 m^2
