If you mean 4 / (11/8)
= 4 * 8/11
= 32/11
= 2 10/11
= 2.909
Answer:
The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
Step-by-step explanation:
Regression Output :
Predictor Coefficient
Constant 3.0979
Square root of items 2.7633
R.sq.- 96.7%
So, with this data the regression equation is,
Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items
Substitute x =22 in equation
Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
I need to answer two questions to ask again sorry
Answer:
Step-by-step explanation:
-3X-3<6
-3X<9
X>-3 (NOTICE THE SIGN CHANGE BECAUSE WE DIVIDED BY A NEGATIVE NUMBER)
(-3,00) INTERVAL NOTATION
X = 4 ; x = 3 + i ; x = 3 - i
(If you get a zero that is adding or subtracting, you always need to write it twice but change the sign do they cancel out)
f(x) = (x-4)(x-3-i)(x-3+i)
Distributing the last two parenthesis first is always the best way to start off
(x-3-i)(x-3+i) has (x-3) in common so it can be separated to
(x-3)^2 + (-i)(+i)
(x^2 - 6x + 9) ; (-i)(+i) is always +1
(x^2 - 6x + 9) + 1
(x^2 - 6x + 10)
Now multiply this with (x-4)
x^3 - 6x^2 + 10x
- 4x^2 + 24x - 40
x^3 - 10x^2 + 34x - 40 = f(x)
