Answer:
The teacher is 1.416667 times taller than the student
Step-by-step explanation:
(5 2/3)/4
=1.416667
What I did was take 22,000 and divide by 100 to get 1 percent of the value (22,000). I got 220. I multiplied 220 by 20 (to get what 20 percent would be) and got 4,400. Now subtract 4,400 twice (or 8,800 once) from 22,000. The value of the car at the end of the second year would be $13,200.
This can be solved using the formula for t test which is = x - mu over standard deviation divided by the square root of the number of samples. In this case, it is 1185 - 1200 over 70 divided by square root of 100 which give us a value of 2.14 which is equal to .9839 in area. Only rarely, just over one time in a hundred tries of 100 light bulbs, would the average life exceed 1200 hours.
To find the dimensions you can just factor the equation...
x^2+4x-21
x^2-3x+7x-21
x(x-3)+7(x-3)
(x+7)(x-3) and this is equal to LW or WL
And note that x>3 for any possible solution.
