Answer:
Step-by-step explanation:
In order to find the slope of a line, we need to find the rise over the run.
Basically - the change in y divided by the change in x.
We can compare the two points and find both.
We go from (0, 2) to (3, 1).
From 0 to 3 (x) is 3 units.
From 2 to 1 (y) is -1 units.
Therefore we can divide the x by the y.
Hope this helped!
Answer:
personally i think x=6
Step-by-step explanation:
but heres how i got it cross multiiply 7.5/4 and x/3.2
witch makes 24=4x then divide by 4 and you get x=6
so.... yeah i think x=6
if brainiest is earned its greatly appreciated
Answer: 24.49 or 24.5 if rounded.
Step-by-step explanation: We have to use the pythagorean theorem of course...
a² + b² = c²
15² + 20² = c²
225 + 400 = c²
600 = c²
c = 24.49 (If we round to the nearest tenth then the answer is 24.5)
Answer:
Step-by-step explanation:
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
