Answer:
Step-by-step explanation:
Given
Probability that an inspector doe not identify low-quality timber=0.20
(a)Probability that both inspector do not identify a low quality timber
(b)Let n be the no of inspector
Probability should be less than 1%=0.01
so 
Taking 
both sides
x>2.861
thus minimum value of x is 3
(c)From part b it is clear that minimum 3 officer are required to to keep the low quality timber below 1%
on an average 2 officer are not sufficient to identify 4 low quality timber out of 100
B. If you multiply 1/12 by (-x) it's -1/12x and if you multiply 1/12 by (-4) it's -4/12 which is equivalent to -1/3.
The standard error for the distribution of sampling proportions will be 0.0686.
<h3>What is standard error for the distribution of sampling proportions?</h3>
In mathematics, the difference between a data set and the populace's true average is known as primary data deviation from the mean.
According to the National Postsecondary Student Aid Study conducted by the U.S.
Department of Education in 2008, 62% of graduates from public universities had student loans.
We randomly select 50 students at a time.
Then the standard error for the distribution of sampling proportions will be

M = (t+1)/(t-3)
m(t-3) = t+1
mt-3m = t+1
(m-1)t = 3m+1
t = (3m+1)/(m-1)
Answer:
-114
Step-by-step explanation:
f(x) = -4x^2 +5x
Let x = 6
f(6) = -4(6)^2 +5(6)
= -4(36) +30
- 144+30
= -114
