Answer:
P = 1.214
Step-by-step explanation:
Draw a normal probability curve.
Find the z score which comes out to be 0.18 (0.181578947)
look for the probability in the table.
look across 0.1 and under 8.
Get the probability and add 0.5 to it
so rhats:
0.714 + 0.5 = 1.214
B, because it is the one that is closest together, and it is like a upside down V, unlike Graph A, which is spread out so much.
Answer:
32
Step-by-step explanation:
let the number be n , then
n + 
n = 12 ( multiply through by 8 to clear the fractions )
2n + n = 96
3n = 96 ( divide both sides by 3 )
n = 32
The number is 32
We can write a proportion between short and long legs:
Solving for k yields
