Answer: mean = 318.3
Median =330
Mode= 200
Step-by-step explanation:
Mean (average) is the total sum of values in a given a data set ÷ number of values
= 3820/12
Mean= 318.3
Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2
Step 1: we rearranged the data set from least to highest value to give
200,200,220, 240,300,320,340,360,380,400,420 and 440
Median= 320 + 340/2
=660/2 = 340
Mode is the value with highest frequency in a given data set, from the given question, mode = 200

Answer:
0.08
Step-by-step explanation:
L = 5W - 10
5W = L + 10
W = 1/5(L + 10)
Area = L x W
240 = L(1/5(L + 10)
L^2 + 10L = 240(5) = 1200
L^2 + 10L - 1,200 = 0

Answer:
2.02 m
or 2 m 2 cm
Step-by-step explanation:
Imagine a triangle containing the 40° angle and that this angle is at the left. Then the height of the truck bed is 1.3 m and the "shortest possible length of the ramp" is the hypotenuse of this triangle. We need to find the length of this ramp, that is, the length of the hypotenuse.
The sine function relates this 40° angle and the 1.3 m height of the truck bed:
sin 40° = opp / hyp = 1.3 m / hyp
which can be solved for 'hyp' as follows:
1.3 m
hyp = ----------------- = (1.3 m) / 0.6428)
sin 40°
1.3 m
Thus, the length of the ramp must be less than -------------- or 2.02 m
0.6428
where this last result is to the nearest cm.
If the ramp is shorter the angle of the ramp will be smaller and the ramp angle considered safer.
