Answer:
2 x 2 = 4
Step-by-step explanation:
If you're trying to find the square root of say, 9, it would be 3 x 3 and your trying to find a square root something it's just something multiplied by itself again. such as the square root 1225 is 35 x 35, because 35 x 35 is 1225. Sorry if this is to complicated for you I learnt this in first term and I found it easy to grasp because of the way my math teacher taught it.
Sorry in advance ¯\_(⸟‸⸟)_/¯
Use the information to write the dimensions of each rectangle in terms of w, the width of the 1st one.
1st rectangle;
l = 2w
w = 2
2nd rectangle:
w = w
l = 2w + 4
If the area of the 2nd rectangle is 70 square meters, you will use the area formula to write an equation that you will solve using the factoring.
A = lw
70 = w(2w + 4)
70 = 2w^2 + 4w
0 = 2w^2 + 4w -70
0 = 2 (w^2 +2w - 35)
0 = 2 (w + 7) (w - 5)
To get zero, the width would need to be -7 or 5. Because it is a distance, it has to be 5 meters.
The width of both rectangles is 5 meters.
Answer:
We can find the critical value 
And for this case if the confidence increase the critical value increase so then this statement is True
Step-by-step explanation:
For a confidence level given c, we can find the significance level like this:
And with the degrees of freedom given by:
We can find the critical value
And for this case if the confidence increase the critical value increase so then this statement is True
