3 because the x value has been repeated

3) {(−1,6),(1,3),(2,5),(1,7)}

Step-by-step explanation:

functions have to pass the vertical line test to be called a function

if they don't pass they are <em><u>not</u></em> a function

this means that no x values can repeat

In option 1

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

1, 2, 3, 4

in option 2

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

4,2,-3,3

in option 3

one of the x values repeats so that means it is <em><u>not</u></em><em><u> </u></em><u>a</u><u> </u><u>func</u><u>tion</u>

-1,<em><u>1</u></em>,2,<em><u>1</u></em><em><u> </u></em> the ones repeat

in option 4

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

-1,0,5,2

so that means that <em>option 3 is not a function </em>

Subtract 3 both sides first. R-3=ts²

next, divide both sides by t, (R-3)/t=s²

finally, take the square root of both sides

√(R-3)/t = s. 2nd choice.

VladimirAG [237]

Step-by-step explanation:

275 \times 5 = 1375

The rate of the motorboat on still water is 1375

405 \times 5 = 2025

The current rate of the motorboat is 2025

Assume that 8​% of people are​ left-handed. We select 6 people at random. ​a) How many lefties do you​ expect? ​b) With what sta
klemol [59]

Answer:

a) 0.48

b) 0.6645

c) 12.5

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they are left-handed, or they are not. The probabilities of each person being left-handed are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

The number of trials expected to find r sucesses is given by

N = \frac{r}{p}

In this problem we have that:

Assume that 8​% of people are​ left-handed. We select 6 people at random. ​

This means that p = 0.08, n = 6

a) How many lefties do you​ expect?

E(X) = np = 6*0.08 = 0.48

​b) With what standard​ deviation?

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{6*0.08*0.92} = 0.6645

​c) If we keep picking people until we find a​ lefty, how long do you expect it will​ take?

Number of trials to find 1 success. So

N = \frac{r}{p} = \frac{1}{0.08} = 12.5
