The slope is 4/3 because rise over run (if u have heard of that expression)
Answer:
I most likely think it is approximately 19%
Step-by-step explanation:
Assuming you mean still receive an allowance even though they dont do chores:
Ok In all the total number of students is 21. Out of those 21, 4 still receive an allowance even though they dont do chores. This is 4/21. Now all we have to do is convert 4/21 into a percentage. To do this we have to divide 100 by 21, then times 4 by that number:
100 / 21 = >> approximately 4.76
Now 4 times 4.76 :
4 * 4.76 = >>> approximately 19.04 % . We round it to 19%.
So the answer is 19%.
Assuming the question marks are minus signs
to find max, take derivitive and test 0's and endpoints
take derivitive
f'(x)=18x²-18x-108
it equal 0 at x=-2 and 3
if we make a sign chart to find the change of signs
the sign changes from (+) to (-) at x=-2 and from (-) to (+) at x=3
so a reletive max at x=-2 and a reletive min at x=3
test entpoints
f(-3)=83
f(-2)=134
f(3)=-241
f(4)=-190
the min is at x=3 and max is at x=-2
My prediction would be 1,659 defective brakes. I hope this helps you
