Let's write it down:
<span>"60 is 75% of s" means:
60=75%*s
75% is

, (percent just means "out of 100" so we just divide it by 100) so we can also write:
60=</span><span>

s
now, let's multiply both sides by 4:
240=3s
and divide by 3:
80=s
So we have the result that the original value, s, is 80!

Simplifying quantity x squared plus 6 x plus 8 end quantity over quantity x plus 2 we get x+4
Option d is correct.
Step-by-step explanation:
We need to simplify quantity x squared plus 6 x plus 8 end quantity over quantity x plus 2.
Writing in mathematical form:

Solving:
Factorizing the numerator:

So simplifying quantity x squared plus 6 x plus 8 end quantity over quantity x plus 2 we get x+4
Option d is correct.

Answer/Step-by-step explanation:
(a) The likelihood function to estimate this probability can be written as:
mat[1000, 9800]p9580(1 - p)420
(b) The value of the maximum likelihood estimate of the probability 0.958(By taking log of expression in (a) above)
(c) when the true probability is 98%, then it implies that 9800 of 10,000 bulbs did last over 6500hours.
Therefore, the likelihood is p(9800) = mat[10000, 9800]p9800(1 - p)200
(d) Method of moments estimate is the estimation of all the parameters of the population sample.
(e) The statement is FALSE because estimates by the method of moments are not necessarily sufficient statistics, because sometimes fail to take into account all relevant information in the sample. As in the above question

simple even tho im in 6th grade it would be over $100
