Answer:
Class second have higher score and have greater spread.
Step-by-step explanation:
For first box plot
For second box plot
First class has greater minimum value, it means first class has lower grades.
First quartile of both classes are same, it means equal number students in both classes have less than 62 marks.
First class has greater median.
second class has greater third quartile.
Second class has greater Maximum value. It means second class have higher score than first class.
Second class has greater range. It means the data of second class has greater spread.
Second class has greater inter quartile range. It means the data of second class has greater spread.
Therefore, the class second have higher score and have greater spread.
Answer:
the answer is that a=2
Step-by-step explanation:
Answer:
f⁻¹(x) = 4x - 2
Step-by-step explanation:
To find the inverse of a function, switch the places of x and y (or f(x)).
f(x) = 1/4x + 1/2 → y = 1/4x + 1/2
Switch the variables.
x = 1/4y + 1/2
Now you want to convert the equation back into y = mx + b form.
x = 1/4y + 1/2
Subtract 1/2 from both sides.
x - 1/2 = 1/4y
Now, you want to isolate y further by dividing both sides by 1/4 (or multiplying by 4).
4(x - 1/2) = y
Distribute the 4.
4x - 2 = y → y = 4x - 2 → f⁻¹(x) = 4x - 2
This is the inverse of your given function.
Answer: is 12
Step-by-step explanation:
Answer:
Yes
