Find the cartesian product Ax B of the following sets a) A = {x:x=1,2,3},b{y:y=3-x}

BabaBlast [244]

Answer:

Step-by-step explanation:

A=(1,2,3)

B=(0,1,2)

A×B=(1,2,3)×(0,1,2)

A×B=((0,1),(1,1),(1,2),(0,2),(1,2),(2,2),(0,3),(1,3),(2,3))

What is the period for the function y = -4 cos (5x +3)? (4.3)

BlackZzzverrR [31]

The periodicity of function is $\frac{2 \pi}{5}$

Solution:

Given that we have to find the period of function

Given function is:

$y = -4 + cos(5x+3)$

Use the below formula:

$\mathrm{Periodicity\:of\:}a\cdot \cos \left(bx\:+\:c\right)\:+\:d=\frac{\mathrm{periodicity\:of}\:\cos \left(x\right)}{|b|}$

Thus,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{\text{periodicity of cos(x)}}{5}$

Now find the periodicity of cos(x)

We know that,

periodicity of cos(x) = $2 \pi$

Therefore,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{2 \pi}{5}$

Thus the periodicity of function is $\frac{2 \pi}{5}$

Since we talked about a Man on the Street survey in class today, you decided to do one yourself! You estimate that there is a 0.

Answer:

Therefore, we conclude that the probability is P=0.3456.

Step-by-step explanation:

We know that there is a 0.60 probability that a random student at UMSL has watched Game of Gnomes. We calaculate the probability that 3 of 4 students watched Game of Gnomes.

$p=0.6\\q=1-0.6=0.4\\$

Therefore, we get:

$P=C_3^4\cdot 0.6^3 \cdot 0.4^1\\\\P=4\cdot 0.6^3 \cdot 0.4\\\\P=0.3456$

Therefore, we conclude that the probability is P=0.3456.
