ok
we are ask for measuring of center
there are 3 different measures
mode, when the data value occurs the most frequently
median, is the data value in the middle of a sorted list of data
mean is the average of the numbers
so the answer is A) mean and median
Answer:
Step-by-step explanation:
We want to to rewrite
Use difference of two squares to get:
This implies that:
This finally simplifies to:
Therefore the required product is
No, this would not be a linear function. Being linear means it creates a straight line, but this function has an x squared. Anytime x^2 is in a function, the graph is a u shape, called a parabola. A simple linear function is y=x :D
if a b 9 are in GP
b÷a = 9 ÷ b
b^2 = 9a
if a - 1 b 9 are in AP
2b = a+8
b = a+8÷2
substitute
b is equal to a + 8 by 2 in b square equal to 9 a
(a+8÷2)^2 = 9a
a^2+16a+64 = 36a
a^2 -20a +64 =0
(a-16) (a-4) =0
a= 16 or a=4
when a=16 b= 12
when a=4 b= 6
Value of a and b are given above
