Those are independent events, so the probability of them both happening is the product of the individual probabilities. Since one spin has a 1 in 5 chance of coming up four, two spins each coming up four has probability
Second choice
Answer:
C) A, J, D, and G
Step-by-step explanation:
Co-planar means that all of the points lie within the same plane, by using the process of elimination you can discover that option C is the only one that does not have all 4 points within the same plane.
Circumference=2πr=2×22/7×4.7=29.5 inch (nearly)
Answer:
<h2>
D. y = cot x</h2>
look at the picture.
cot(x) not exist for x = kπ, k∈Z
(vertical asymptotes ...,-2π, -π, 0, π, 2π, ...)
tan(x) not exist for x = π/2 + kπ, k∈Z
(vertical asymptotes ...,-3π/2, -π/2, π/2, 3π/2, ...)
csc(x) not exist for x = kπ, k∈Z
(vertical asymptotes ...,-2π, -π, 0, π, 2π, ...)
cos(x) exist for any value of x
