Answer: Third option.
Step-by-step explanation:
You know that the drawbridge rises at a rate of
feet per minute. This means that the drawbridge rises
in a minutes.
Convert from mixed fraction to decimal number:
Since the drawbridge rises to a height of 50 feet, you need to apply this procedure in order to find the time the drawbridge takes to completely rise:
or
First, convert 3 tons to ounces.
3 tons = 96,000 ounces. Divide this by 12 ounces.
96,000/12 = 8000
So, 8000 boxes can be filled each week!

Answer:
Answer choice A(57%)
Step-by-step explanation:
The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)
Answer:
the answer is: '-2'
Step-by-step explanation:
" A residual value is a difference between observed y-value(from scatter plot) and the predicted y-value( from regression equation line) ".
when we look at the scatter plot we see that the value of y at
is 
,and when we substitute the value
into the given equation 
we get 
so, the residual value is given as: 
Hence, the residual value at x=-2 is -2.
