First there are 10 socks in total and there are five red socks. The probability is 5/10 or 1/2.
Answer:
A
Step-by-step explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
Answer:
5-3x
Step-by-step explanation:
To expand this, we start with the distribution of -3 into the parentheses containing x+2
This leaves us with
11-3x-6
From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6
We combine them by subtracting 11-6 to get 5.
This leaves us with our answer,
11-6-3x
<u>5-3x</u>
An alternate way of writing this would be
<u>-3x+5</u>
But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now
The terms that come from expansion through Pascal's Triangle are x^3+9x^2+27x+27. The third term in this sequence is 27x. This is your answer.
