(x + 2)(7x - 1) + 3x^ -2
= 7x^2 + 14x - x - 2 + 3x^2 - 2
= 10x^2 + 13x - 4 Answer
Its choice A
The answer is c u welcome
Y= mx+b (I think) m is the slope, and b is the y intercept
F ( x ) = x + 4
x = 3 p
f ( 3 p ) = 3 p + 4
Answer. D )
The ordered pair is:
( x, y ) = ( 3 p, 3 p + 4 )
Thank you.
The mean of the frequency distribution is 6.0 .
In mathematics and statistics, the arithmetic mean or arithmetic average is referred to as the sum of a set of numbers divided by the total number of numbers in the set.
The formula to calculate mean is,
Mean = sum of all observations / total number of observations
x = 4 5 6 7 8
f = 12 1 8 18 4
∑f = 12 + 1 + 8 + 18 + 4 = 43
fx = 48 5 48 126 32
∑fx = 48 + 5 + 48 + 126 + 32 = 259
Mean = ∑fx / ∑f
Mean = 259 / 43
Mean = 6.02
Mean = 6.0 ( After Round Off )
So, we can conclude that the mean of the frequency distribution is 6.0 .
