Mean is when you take all the numbers and add them together and divide by the amount of numbers there
Example: Find the mean of :3,4,6,7
So you a 3+4+6+7=20 divide that by 4(because there you added 4 numbers) and that equals 5
Answer:
the answer would be 2x^2-4x
Given
12 black socks
16 white socks
Without looking, Mario takes one sock out of the drawer and then takes out another without replacing the first sock
Which expression shows one way to find the probability that he will take out two white socks?
Procedure
for the first white socks
for the second white socks
Answer: Choice C. (x-7)(x-8)
-------------------------------------------------------
Find two numbers that...
* Multiply to 56 (last term)
* Add to -15 (middle coefficient)
Those two numbers are -7 and -8. So that's why x^2-15x+56 factors to (x-7)(x-8)
D. 360 cm squared
Explanation:
Multiply each faces edges.
18x7(WxL)
3x6(HxW)
3x18(HxL)
multiply each equations answer by 2, because the opposite face is the same.
108x2=216
18x2=36
54x2=108
add these together to get 360 cm squared.
