Answer:
.Lower quartile = 3.5
Step-by-step explanation:
Rearranging the data from lowest to highest.
2, 3, 4, 5, 6, 7, 8, 9 , 10, 15
First finding the median to make it easier to find the lower quartile.
median : 6 and 7 but right now they're irrelevant so we don't honestly need to work that out.
The lower quartile would be 3 and 4
3+4= 7 divide by 2 = 3.5 is your lower quartile
Answer: y = 3/2x + 5
Step-by-step explanation:
Find the slope/gradient:
Plug in a point to the equation:
Solve for b:
New equation:
F (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing: you plug –1 in for x, multiply by the 2, and then add in the 3, simplifying to get a final value of +1
(6-x)=24
X=-18
If you subtract a negative number with a positive number it adds them together making it positive (6- -18)=24
Answer:
the answer is D
Step-by-step explanation:
I don't know how to explain it very well but the line starts at 2 then ends at 8
