Answer:
Answer: √49
___________
√49 = 7
Step-by-step explanation:
The area of a square is equal to the square of its side or the product of its side and its side.
A = s², because the sides of a square are congruent.
Answer:
D, 64%
Step-by-step explanation:
To solve algebraic equations, you have to do the inverse or opposite, so because you are multiplying x by 50 on one side and x wants to be alone, you have to do the opposite which is divide by 50 to get x*1 or just x (because 50/50 equals 1) and what you do on one side of the = sign you do on the other, so 32/50 = 0.64. Then to make a percent you move the decimal to the right by 2 places and you get 64%
Step-by-step explanation:
let's simply do the multiplications and then compare with the original.
(x-m)² + n
right ?
or is it
let's go for the first.
x² - 2mx + m² + n = x² - 3x
-2mx + m² + n = -3x
fun there we see two things :
-2m = -3
m = 3/2
and
m² + n = 0
(3/2)² = -n
9/4 = -n
n = -9/4
so our transformed expression looks like
(x - 3/2)² - 9/4
Answer:
Independent
Step-by-step explanation:
Dependent Sampling:
Dependent sampling is one in which the individuals in one sample are used to determine the individuals in the other sample.
But the third dash graders are divided into two groups independent of each other.
So the sampling is independent.
It is qualitative because it is showing quality irrespective of the number of students .
Quantitative Sampling is one in which the results change with the number of the individuals / tests etc. But in this experiment the number of the students is fixed so it is showing quality rather than quantity.
The point Q will satisfy the equation y=-2x+3 if the coordinates are plugged into the equation, so we plug in our known coordinate of the point Q (y = 3) and then we solve for x:
3 = -2x + 3
subtract 3 from both sides
0 = -2x
divide both sides by -2
x = 0
so the coordinate Q is (0,3)
