When there are few data, we often fall back on personal probability. There had been just 24 space shuttle launches, all successf

ul, before the Challenger disaster in January 1986. The shuttle program management thought the chances of such a failure were only 1 in 100,000. Suppose 1 in 100,000 is a correct estimate of the chance of such a failure. If a shuttle was launched every day, about how many failures would one expect in 300 years? [a] (Round to the nearest integer.)

Answer:

  1

Step-by-step explanation:

There are about 110,000 days in 300 years, so the expected number of failures is about 10/11 ≈ 1.

_____

This assumes the launch conditions are identical for each of the launches, or that whatever variation there might be has no effect on the probability. These are bad assumptions.

Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, \mu = $23,500

Sample mean,\bar{x} = $24,500

Sample standard deviation,s = $2,800

Sample size, n =  146

Confidence interval:

\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}  

Putting the values, we get,

t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436

24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)

The confidence interval is (24116.3878,24883.6122).

How do I do this?? 7-11
mihalych1998 [28]

Answer: slope intercept is y=mx+b form s b= the y intercept and x will just be x and the m is usually a fraction which tells you the slope so what you need to do is mark these points on a line graph draw a line from one to the other and every where it crosses over a point is where you can find the slope and the y intercept giving you the answer

The coordinates of point P on a coordinate grid are (−5, −6). Point P is reflected across the y-axis to obtain point Q and acros
Llana [10]
Hey friend!
Let's figure this out!

P(−5, −6)
reflect about y axis
Q(5, -6)
reflect about x axis
R(5,6)


So that gives you the answer!
3. Q(−5, 6) and R(5, −6)



Hope this helped!
