Solve x≤0 and x≥−4 and write the solution in interval notation. If there is no solution, type ∅.
xxTIMURxx [149]

The answer is (-∞.∞).

Draw out a number line. Plot 0 and -4 on the number line.

Shade to the left of x = 0, and have a filled in circle at the endpoint. This is the graph of x≤0

Then graph x ≥−4 by plotting a filled in circle at -4, and shading to the right.

Note how the two graphs overlap to cover the entire real number line

So if we have x≤0  or  x≥−4 then we're basically saying x is any real number. To write this in interval notation, we write (−∞,∞)

This is the interval from negative infinity to positive infinity (or just infinity). We exclude each endpoint because we can't actually reach infinity itself. Infinity is not a number. Infinity is a concept

Side note: if you change the "or" to "and", then the solution to x≤0  and  x≥−4 would be [-4, 0][−4,0] to indicate the interval from x = -4 to x = 0, including both endpoints. This is the region where the two graphs overlap.

Determine whether or not the procedure described below results in a binomial distribution. If it is not​ binomial, identify at l
ArbitrLikvidat [17]

Answer:

a) it is not a binomial, it is hypergeometric distribution.

Step-by-step explanation:

a) Four hundred different voters in a region with two major political​ parties, A and​ B, are randomly selected from the population of 3000 registered voters.

it is not a binomial because the probability of succes changes between one trial and another one, so the trials are not independent.

The cost of printing books C varies partly as the amount A charged by the printer
lawyer [7]

The equation connecting C,A and n is  C = 25A - \frac{49990000}{n}

<h3>What is variation?</h3>

Variation is a mathematical term used to show how a quantity behaves when one quantity increases or decreases.

Analysis:

C = AK + M/n

where K and M are constants

when n = 1000, A = 5000, C = 75010

75010 = 5000K + M/1000-----------1

50004 = 10000k + M/200-------------2

solving simultaneously,  K = 25, M = -49990000

C = 25A - 49990000/n

In conclusion, the equation connecting C,A and n is C = 25A - 49990000/n
