Answer:
(C) A model with 21% training error, 21% validation error, and 75% sensitivity.
Step-by-step explanation:
In best classification models training error is equal to validation error, therefore A model with 21% training error, 21% validation error, and 75% sensitivity is most likely to be the best when applied to the test sample.
Long Piece: x + 18
Short Piece: x
(x) + (x + 18) = 84
2x + 18 = 84
2x = 66
x = 33
Long Piece: x + 18 = (33) + 18 = 51
Answer: 33 meters and 51 meters
Answer:
Option D.
Step-by-step explanation:
To find the inversion of a function follow the following procedure
1) Replace x with y in the function and clear y
------> 


2) Check. The range of f(x) is the domain of
.
So if f(a) = b, this means that
= a.


Is fulfilled. Therefore
is the inverse of 
Answer: 11/30
Step-by-step explanation: looking at this question that was given to us and to find the probability, then we will go by saying that;
Probability of an event (E) = number of outcome of Event E/total number of all event
Prob(Basebase player)=11/30
Going by this, then we are going to have our answer as 11/30
Answer:
B. $79 + 0.1($79)
Step-by-step explanation:
Given that;
the shipping cost for an order = 1/10 multiply by the cost of the items bought;
i.e. 
where
x = cost of items ordered for.
This implies that:
x + 0.1x
The objective is to determine the expression for the total cost of an order which is $79
x = 79
Then, the total cost of an order is
$79 + 0.1($79)
