The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
I'm sorry, but I don't know how to do the standard deviation...
Hope this helped!
Same as before
total=(2w+75)(2w+35)=4w²+220w+2625
pool=75 times 35=2625
minus pool from total
4w²+220w+2625-2625=4w²+220w
-3^2= -(3)^2
The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.
We can divide each digit by 7. So 56/7=8 and 21/7=3
so.... 8:3
You go A to B & B 2A + 8 + B to A&A to B&B to a and then you go see 2D to see 2D to see you today to see 2D which equals a + 8 + 8 + 8 + 8 and that's your answer for this question I know it doesn't look like it makes sense but it's correct I think
