Answer:
See the figure attached
Step-by-step explanation:
Let's call :
x: positive response
y: negative response
then the score is:
2x - 3y
A career placement test eliminates a profession when a person receives a score of 18 or less, that's represented by the following inequality:
2x - 3y ≤ 18
Answer:
The true mean
it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:

For this case the value for the sample size is n =190 and the calculated sample mean is
. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean
since we probably have variability from the data of the students at City College.
So we can conclude that the true mean
it probably could be larger, smaller, or equal to 22
Answer:
here ya go
Step-by-step explanation:
-5 + -4 = -9
17 - 6 = 11
(negatives cancel out) -13 + 5 = -8
(negs cancel out again) -6 + 3 = -3
Answer:
length = 3x = 3 × 11 = 33 m
breadth = 2x = 2 × 11 = 22 m
Step-by-step explanation:
here's the solution :-
let's take the ratio constants be x
so, length = 3x
breadth = 2x
And, we know that area of rectangle =
length × breadth
So,
=》

=》

so, length = 3x = 3 × 11 = 33 m
breadth = 2x = 2 × 11 = 22 m
