Answer:
Step-by-step explanation:
Some facts to establish before we try to solve: 
and another way of writing 
is 
. Also order of operations: PEMDAS
For the first option:
We solve what is in the parenthesis: 2*2=4*2=8*2=16*2=32*2=64 so , which is another way to write
For the second option: If the square root of 64 is 8, the there is no way we can multiply another value by it.
The third option: When dealing with square roots, we can solve the inside first and then take the square root:
definitely not 64 (though if you're curious it's 4096)
The fourth: Another way to write the square root is to raise the value to the 1/2 power so
Which is the same as
Fifth: Like the third, we solve the inside of the square root first
16*4= 64 and then
Sixth: We need a nice whole number (8), and 
has no clean roots, so its result will have decimals. It can't be our answer
Answer:
zero
Step-by-step explanation:
The optimally fitted straight line via the locations and points on a graph is determined via linear regression. You may use regression equations to see if your data can indeed be fitted into a formula. If you want to create assumptions from your data, either future forecasts or indicators of previous behavior, using the Regression equation is highly beneficial.
The regression line is expressed as:
where;
= dependent variable
a = intercept
b = slope
= independent variable
So, when is independent of the variation of , it means that does not linearly depend on . Thus, the slope of the regression will be zero.
Answer:
(1/2 ,3) or (0.5, 3) is the same
Step-by-step explanation:
The midpoint between (3,5) and (-2,1) would be:
Apply the formula:
x1+x2 / 2 , y1 + y2 / 2
= 3 + (-2) / 2, 5 + 1 /2
= 1/2, 6/2
= 1/2 ,3 or 0.5, 3 is the same
Hope this helped :3
Answer:
False
Step-by-step explanation:
They will have different angle measures and un-proportional sides, making them non similar.
