Answer:
B is the correct option.
Step-by-step explanation:
We have to find the inverse of the logarithmic function
Below are the steps to find the inverse:-
Step 1:-
Set f(x) =y
Step 2:-
Interchange x and y
Step 3:-
Solve for y
We know the relation:-
If
Using this relation, we have
b=2
Step 3:-
The value of y is the inverse of the function.
B is the correct option.
Answer:
Step-by-step explanation: The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The probability of selecting a respondent who does not prefer Cell C is 0.775
<h3>How to determine the probability?</h3>
The complete question is in the attached image
From the attachment, we have
Prefer cell C = 90
Total = 400
So, the number of respondents that do not prefer cell C is
Do not = 400 - 90
Do not = 310
The probability is then calculated as:
P = 310/400
Evaluate
P = 0.775
Hence, the probability of selecting a respondent who does not prefer Cell C is 0.775

4^6(x^8)(y^-2) / 4^7(x^4)(y^2)
= 4^-1(x^4)(y^-4)
= x^4 / 4y^4
Therefore A is the correct answer. Obtained using exponent laws.
Laws used:
- Anything to the power of 0 is 1, which eliminates the base.
- When you divide like bases with exponents, you subtract the exponents to simplify.
