Answer: correct option is A

0.100

Step-by-step explanation:

Given that

population = 500 elements.

To draw a simple random sample of 50 elements from this population. On the first selection

The probability = 50/500 = 0.1

The probability of an element being selected is 0.100

In one town, 66% of adults have health insurance. What is the probability that 4 adults selected at random from the town all ha

LiRa [457]

Answer:

Probability that randomly selected 4 persons all have insurance is = 0.1897

Step-by-step explanation:

Given that the probability of having an insurance equals 66%=0.66

Thus

Probability that person A has insurance = 0.66

Probability that person B has insurance = 0.66

Probability that person C has insurance = 0.66

Probability that person D has insurance = 0.66

Probability that randomly selected 4 persons all have insurance is

$P(A)\times P(B)\times P(C)\times P(D)\\\\=0.66\times 0.66\times 0.66\times 0.66=0.1897$

In two or more complete sentences, describe how you would draw the graph of the solution set for the following inequality. -3m+1

Marat540 [252]

First find the value of m by solving the inequality.

Solving the inequality we get value of m: m>-4

Now, for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.

Step-by-step explanation:

We need to draw the graph of the solution set for the following inequality. $-3m+18 < 30$

First we will solve the inequality and find value of m

$-3m+18 < 30$

Adding -18 on both sides

$-3m+18-18 < 30-18\\-3m$

Dividing both sides by -3 and reversing the inequality i.e < is changed into >

$\frac{-3m}{-3}-4$

So, value of m is: m>-4

So. for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.

The graph is shown in figure attached.
