Answer:
9
Step-by-step explanation:
Loblolly Pine is 3 in 150
450/150 times 3 Loblolly Pine = Loblolly Pine in 450 square meteres
450/150 = 3
3 times 3 = 9
No it is not greater because the whole number is bigger
Answer:
The answer is E. Impossible to determine
Step-by-step explanation:
Normally, you would find the Confidence interval of a normal sample by using
X(-+) Z* Sigma/n
Where x is the mean, sigma the standard deviation n the size of the sample and z the value determined by your confidence interval size of 95%
.However, this approximation of a confidence interval may only be used for a sample if the number of observations is at least 30 or above. When we have less observations than 30 we must use the standard deviation of the populations. But we only have a sample standard deviation so its not adequate or possible to determine CI the true mean of the population with such a small sample size.
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
If we go back to the defenition of logs, we can find this solution quickly.
What you're saying when you say ㏒₂(5x+7) = 5 is that
2⁵ = 5x+7
So
32 = 5x+7
25 = 5x
x = 5
