After the 3rd pick we have: 4 white, 3 red and 8 black marbles.
The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143
They need to sell 33, unless you round it up then 34.
Answer:
side length= 4 mm
Step-by-step explanation:
The explanation is pretty easy;
You know that to get the volume of a cube the formula is length times width times height. You also know that all sides of a cube are equal. so what multiplied by itself 3 times = 64?
That would be 4; 4 times 4 = 16 then 16 times 4 = 64
<em>Sorry if the explanation wasn't great:(</em>
ANSWER
1. k=13
2. x=-10
EXPLANATION
The given function is
To find f(x+5), plug in (x+5) wherever you see x.
This implies that:
Expand:
Simplify to obtain
We now compare with,
This implies that:
To find the smallest zero of f(x+5), we equate the function to zero and solve for x.
The smallest zero is -10.
