Answer:
7
Step-by-step explanation:
Step-by-step explanation:
Given expression;
2x + y = -5;
The given equation must be written in a form where the slope is the negative inverse of the given one.
A line perpendicular to another will have a negative inverse slope.
2x + y = -5
Equation of a straight line is generally written as;
y = mx + c
y and x are the coordinates
m is the slope
c is y - intercept
2x + y = -5
y = -2x -5
The slope of the perpendicular =
So,
the new line;
y =
x -5
Any line with slope of
will be perpendicular
Answer:
19958400 ways
Step-by-step explanation:
As the question involves arrangement, permutation will be used.
P(n,r) = n! / (n-r)!
Here
n=12
and
r = 8
So,
P(12,8) = 12!/(12-8)!
= 12!/ 4!
=19958400 ways
Therefore, the 8 objects from 12 can be arranged in 19958400 ways ..
Answer:
Step-by-step explanation:
Smaller values of the standard deviation result in a normal curve that is narrower and more peaked.
