Two angles are vertical angles. If the angles are also complementary angles, what is the degree of the angle

1 answer:

4 0

Vertical angles are congruent according to the vertical angles theorem. If they are complementary as well, then they both sum up to 90 degrees. So, form an algebraic equation!

x+x=90 or 2x=90... Using the division property of equality, the angle measure (or x) equals 45...

Happy Solving!

What is the slope of the line through (3, 2) and (-3 ,4)

Delicious77 [7]

Answer:

Slope = $-\frac{2}{3}$

Step-by-step explanation:

Slope = $\frac{rise}{run}$

Slope = $\frac{y2-y1}{x2-x1}$

Slope = $\frac{4-2}{-3-3}$

Slope = $-\frac{4}{6}$

Slope = $-\frac{2}{3}$

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the

maria [59]

Answer:

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

Step-by-step explanation:

Given that:

Total Number of cameras (n) = 8

Defective cameras = 4

X: number of defective cameras

For a binomial distribution :

P(x) = nCx * p^x * (1 - p)^(n - x)

Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5

If 2 samples are chosen at random :

Then, the binomial probability distribution will be :

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
