The height is 15 feet.
0.5xbxh<_120 (equate formula for area of triangle to 120)
0.5x16xh<_120
16xh<_240 (120 divided by 0.5)
h<_15 (240 divided by 16)
Answer: 200 randomly selected students in the school
Step-by-step explanation:
Population refers to a total set of observation that can be made, a whole group or entire set which we desire to observe or test. While sample refers to a smaller manageble version of a population on which testing could be done. Samples should be selected randomly and should contain characteristics of the larger group.
In the case above the sample is the 200 randomly selected students in the school because because that is the selected set of people from which testing was done to draw conclusions about the whole population.
Answer:
f(x) = 7.5x
Step-by-step explanation:
you can find the slope by using the slope formula (y2-y1)/(x2-x1). you can use any of the values but for this example I'll be using (2, 15) and (4, 30).
(30-15)/(4-2) = 15/2 = 7.5.
now we can use one of the coordinates to find the y-intercept by plugging the known values in the equation y=mx+b where m is the slope and b is the y-intercept.
for this example I'll be using (2, 15) but you could use any of the values you gave.
15 = 7.5(2) + b
15 = 15 + b
0 = b
so now we have the function rule
f(x) = 7.5x + 0 or just f(x) = 7.5x
There should be a proof in the text book that matches the one your working on, just copy the stuff into what you're working on.
There is one potential solutions and no extraneous solutions.
