Answer:
4.5 I hope I was not to late
9 + 8 + 3x
you can only add like terms
9 and 8 are like terms so you can add those
but 3x does not have any like terms
so the answer is
17 + 3x
Answer:
Step-by-step explanation:
Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)
Since, slope of a line passing through two points and is given by,
Slope =
Slope of AB =
=
Slope of AD =
= Not defined (Parallel to y-axis)
Slope of DC =
=
Slope of BC =
= Not defined (Parallel to y-axis)
Slope of AB = slope of DC =
Slope of BC = slope of AD = Not defined (parallel to y-axis)
As per property of a parallelogram,
"Opposite sides of a parallelogram are parallel and equal in measure"
Therefore, ABCD is a parallelogram.
I believe that that is an irrational number. It appears to go on without ending and without repeating.
Answer:
n=40 boys
Step-by-step explanation:
-Margin of error is given by the formula:
-The z score for a probability of 92% is 1.75
#We make n the subject of the formula and substitute at a 92% confidence:
Hence, he needs approximately 40 boys for the study
