357
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
because you do 2-1 and then 3 * 3 the equation would look like this
1 + (3*3) /
1+9/ 3
1 + 3
4
Answer: ![0.861](https://tex.z-dn.net/?f=0.861%3C%5Cmu%3C%200.865)
Step-by-step explanation:
The confidence interval for population mean
is given by :-
, where n=sample size
= sample mean
=sample standard deviation
= critical t-value (for two tailed )
Let
be the confidence interval for the population mean mercury concentration.
As per given , we have
Sample size : n= 28
degree of freedom = 27 [df=n-1]
Sample mean :
cc/cubic meter
Sample standard deviation : s= 0.0036
Significance level : ![\alpha=1-0.98=0.02](https://tex.z-dn.net/?f=%5Calpha%3D1-0.98%3D0.02)
Critical two-tailed test value :
(Using t-distribution table.)
We assume the population is approximately normal.
Now, the 98% confidence interval for the population mean mercury concentration will be :-
Required confidence interval : ![0.861](https://tex.z-dn.net/?f=0.861%3C%5Cmu%3C%200.865)
Logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.
<h3>What is the Logarithm function?</h3>
A log function is a way to find how much a number must be raised in order to get the desired number.
![a^c =b](https://tex.z-dn.net/?f=a%5Ec%20%3Db)
can be written as
![\rm{log_ab=c](https://tex.z-dn.net/?f=%5Crm%7Blog_ab%3Dc)
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Given to us
2⁵ = 32
As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,
![2^5 = 32\\\\\rm log_2 32 = 5](https://tex.z-dn.net/?f=2%5E5%20%3D%2032%5C%5C%5C%5C%5Crm%20log_2%2032%20%3D%205)
Hence, the logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.
