What is the length of CO?

Answer:

Pythagorean theorem, eh?

Step-by-step explanation:

The way to do this is use the radius-tangent angle theorem thing...

It states that, a radius that intersects a point of tangency(I think that's what it's called) is perpendicular to the tangent. Thus, CW is perpendicular to OW!

Thus, it forms a right triangle, where we can use Pythagorean Theorem!

If you don't know what it is, check the internet! It's pretty simple.

CW^2+OW^2=OC^2\\144+81=OC^2\\225=OC^2\\OC=15

So, there you go! Hope this helps!

NOTE: This answer was recently deleted for violating community guidelines, so I just re-uploaded it!(and edited it) So if you do need more help, do some research!

A random sample of 56 fluorescent light bulbs has a mean life of 645 hours. Assume the population standard deviation is 31 hours
bezimeni [28]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the population mean.

Number of sample, n = 56

Mean, u = 645 hours

Standard deviation, s = 31 hours

For a confidence level of 95%, the corresponding z value is 1.96.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

645 ± 1.96 × 31/√56

= 645 ± 1.96 × 4.142

= 645 ± 8.12

The lower end of the confidence interval is 645 - 8.12 =636.88

The upper end of the confidence interval is 645 + 8.12 =653.12

Therefore, with 95% confidence interval for the population mean life of fluorescent light bulbs is between 636.88 hours and 653.12 hours
