Answer:
0.28
Step-by-step explanation:
If the probability that the student does take statistics is 0.72, then it must mean that the rest of the students will not take statistics.
1 - 0.72 = 0.28
0.28 will be the probability that the student does not take statistics.
I agree with the person above, I think its C
Using the equation y=9x you can substitute x for the hours. Y=9 times 5 and y=9 times 8. Y=45 and y=72. The range is $45-$72
Equailateral means that base=40mm
solve for height
split the triangle in half with a line perpendicular to the base
now you have 2 right triangles with base 40/2=20 and hypotonuse 40
solve for height or the other side
use pythagorean theorem
a^2+b^2=c^2
20^2+b^2=40^2
400+b^2=1600
subtract 400 fromb oth sides
b^2=1200
square root boht sides
b=√1200=20√3
the height =20√3
area of triangle=1/2base times height
base=40
height=20√3
1/2 times 40 times 20√3=20 times 20√3=400√3
the area is 400√3 mm^2
Answer:
slope = -8/3 (-8 over 3)
Step-by-step explanation:
rise over run
rise is negative since the line is going down = -8
run = 3
