A parabola is a curved shape in a graph that has either a maximum or a minimum (which is the fixed point) and any point is equidistant from that fixed point. You can tell it is a parabola because most likely in an equation the x with be squared.
Standard error (SE)
Or
Therefore, SE of the mean = (8)/(2) =4
No circumference of a circle is very easy to me
SA=(a+b+c) h+bh
=(5+12+13)*4+5*12
=20*4+60
=80+60
=140 cm squared
A rational number is: A number that can be written as a quotient of 2 integers, where the divisor is not 0.
Example: 2/5 , -6,
Because you can write any integer as a quotient with a denominator of 1, all integers are rational numbers,
Example: 5 = 5/1
