Answer:
Substituting 4 for x:
ƒ(4) = 3(4 - 5)
ƒ(4) = -3
So, ƒ(4) = -3
Step-by-step explanation:
Answer:
x = the price of one coffee mug.
n = number of coffee mugs sold
115.50 = x × n
n = 115.50÷ x
you cant solve it without additional informations.
Answer:
B.) 6
Step-by-step explanation:
Given the data:
64 53 60 60 56 58 51 55 60
Reordered data : 51, 53, 55, 56, 58, 60, 60, 60, 64
Interquartile range = upper quartile (Q3) - Lower quartile (Q1)
Q3 = 3/4(n+1)th term
n = sample size = 9
Q3 = 3/4(9+1) = 3/4 (10) = 30/4 = 7.5 th term
Q3 = 60
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(9+1) = 1/4 (10) = 10/4 = 2.5 th term
Q1 = (53 + 55) / 2
Q1 = 54
Q3 - Q1
60 - 54 = 6
Your answer would be option C. x² + y² + 6x - 24y + 128 = 0.
This is because the formula for the equation of a circle is (x - [x coordinate])² + (y - [y coordinate])² = radius², so you have to substitute in the coordinates and the radius, and then expand and simplify. I have done this in paper as it is easier to write than type, but let me know if you would like me to explain any part of it.
I hope this helps!
