I think 0 but if I am wrong I'm sorry
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
A scalene triangle is a triangle with no sides equal. Consequently, all the angles are not equal as well.
When all the sides are equal, it's called an equilateral triangle.
When two sides are equal, it's called an isosceles triangle.
Answer: C
m = slope
m = (y2 - y1) / (x2 - x1)
2 points:
(2, -4) x1 = 2 and y1 = -4
(0, 4) x2 = 0 and y2 = 4
m = (4 - (-4)) / (0- 2)
m = 8 / -2
m = -4
Equation of the line is : y = mx + b
So we got...
y = -4x + b
Then we can use any of the two points given to solve for b. I’m going to use (0, 4).
y = -4x + b
4 = -4(0) + b
4 = 0 + b
4 = b
Therefore the equation of the line is
y = -4x + 4
Answer: It depends on which variable you're solving for.
Step-by-step explanation:
Solving for b: b=7/8mx + -1/8xy
Solving for m: m=xy+8b
______
7x
Solving for x: x=-8b
___
-7m+y
Solving for y: y=7mx-8b
______
x
