Answer: 65
adding all flat surfaces equals 65
12+24+12+16+25 = 65
Answer:
Factor.
Step-by-step explanation:
In Mathematics, the quadratic formula is used for determining the two factors (roots) of any quadratic equation.
The standard form of a quadratic equation is ax² + bx + c = 0
Mathematically, the quadratic equation is given by the formula;
Hence, the quadratic formula allows us to find factor solutions to any quadratic equation.
Answer: b. 3
Step-by-step explanation:
We know that , the indicator variable is a dummy variable in regression analysis which is used to denote either presence ( by 1 ) or absence ( by 0 ) of a nominal variable that can be responsible for the change in output.
Number of indicator variables = (all levels in the original variable)-1
Here , the given categories as per the location are northeast, northwest, southeast, or southwest.
i.e. all levels in the original variable = 4
Then, the umber of indicator variables we need = 4-1 =3
Hence, we need 3 indicator variables.
Thus , the correct answer is b. 3.
Answer: if u mean 3.05 x 10^6 then Hannah is correct.
Step-by-step explanation:
With scientific notations you should have one number on the left side of the decimal so 3.05 is correct and since you move the decimal to the right six times you would get 3.05 * 10^6
