Answer:
Step-by-step explanation:
N(106,14²)
(calculated using excel, let me know if you were supposed to use a normal table) = 0.4715
85.34
Q1:96.56
Q3:115.44
IQR (which is Q3-Q1)= 115.44-96.56= 18.88
Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.
Best of Luck!
Answer:
x = 15
Step-by-step explanation:
6/4 = 1.5
1.5*10 = 15
Check your work:
15/10 = 6/4 = 1.5
x = 15 is right
