Answer:
The correct option is option B.
Step-by-step explanation:
The given function is
We can rearrange the function as
⇒ 3(x - 4)² - 2 = 18y - 36
⇒ 3(x - 4)² = 18y - 34
⇒ 
⇒ 
⇒ 
Therefore, the inverse function will be, 
Therefore, the correct option is option B. (Answer)
Answer: Its B

Answer:
75.
Step-by-step explanation:
If the mean is 75 miles per gallon and the standard deviation is of 10 miles per gallon, it means that most values will fall between 65 and 85 miles.
The percentile 50 falls in the middle of this range, therefore, the value that represents the 50th percentile will be:
(65 +85) / 2 = 150 / 2 = 75.
Answer:
864.36 boxes
Step-by-step explanation:
In the question above, we are given the following values,
Confidence interval 95%
Since we know the confidence interval, we can find the score.
Z score = 1.96
σ , Standards deviation = 15mm
Margin of error = 1 mm
The formula to use to solve the above question is given as:
No of boxes =[ (z score × standard deviation)/ margin of error]²
No of boxes = [(1.96 × 15)/1]²
= 864.36 boxes
Based on the options above, we can round it up to 97 boxes.
