butalik [34]

Answer:

C) Uniform distribution

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.

We can calculate the probability.

Uniform probability distribution

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformily distributed over a 90 minute interval, that is, between 0 and 90, so $b = 90$ and $a = 0$ .

We want to find $P(X \leq 15) = \frac{15-0}{90-0} = 0.167$

Answer: 4/5

Step-by-step explanation:

The slope : rise over run, or the change in y/ change in x

Change in y = 40 (50 - 90)

Change in x = 50 (50 - 100)

40/50 or 4/5

taurus [48]

Step-by-step explanation:

If the library surveyed 240 people and only 15% chose documentaries, then only 36 people chose documentaries and the other 204 chose something else other than documentaries. You had to get 15% into decimal form and to do that you move the "." in 15.0% left 2 places so you get 0.15. Then you multiply 240 by 0.15 and you get 36.

Answer:

$- 4 + 3b {}^{2 } = 143 \\ 3b {}^{2} = 143 + 4 \\ 3b {}^{2} = 147 \\ b {}^{2} = \frac{147}{3} \\ b {}^{2} = 49 \\ b = 7$
