8% of the kids are left handed. I used 12/150 to yield 0.08 which equals 8%
Answer:
14.48 ft
Step-by-step explanation:
The relation between the location of the focus (c), the vertex on the major axis (a) and the vertex on the minor axis (b) with respect the center is:
b² = a² - c²
From the question:
c = 4 ft
a= 30/2 = 15 ft
Replacing into the equation:
b² = 15² - 4²
b = √209
b = 14.48 ft
So, he should build the whisper chamber at 14.48 ft out from the center along the minor axis
D. 5root3
x = 15/root3 = 15root3/3 = 5root3
We can write a system of equations.
x + y = 77
y = x + 5
Plug in x + 5 into the first equation:
x + y = 77
x + (x + 5) = 77
So this is our answer.
Answer:
Read a bit so you can understand which one you want.
<u>Percentage</u>
15 skittles, 3 of the 15 are orange.
3 over 15, or 0.2 as a percentage.
So there is a 0.8% chance that he will NOT pick an orange skittle.
<u>Fraction</u>
15 skittles, 3 over 15.
3 over 15 can be 1 over 5.
So there is a 4 over 5 chance that he WONT grab an orange skittle, pretty good odds.
