Answer:
4 square feet
Step-by-step explanation:
We can see that the dimensions of the hole in the carpet are 2ft by 2ft. All we have to do is find the area of that shape. Since the two side lengths are the same, and the shape appears to have 4 right angles in each of its corners, we can deduce that the shape is a square. We know that the area of a square can be found by multiplying the length and width measurements of the shape:
2ft * 2ft
= 4 ft²
Answer:
And the best option would be:
c. 1450 +/- 12
Step-by-step explanation:
Information provided
represent the sample mean for the SAT scores
population mean (variable of interest)
represent the sample variance given
n=25 represent the sample size
Solution
The confidence interval for the true mean is given by :
(1)
The sample deviation would be
The degrees of freedom are given by:
The Confidence is 0.954 or 95.4%, the value of
and
, assuming that we can use the normal distribution in order to find the quantile the critical value would be
The confidence interval would be
And the best option would be:
c. 1450 +/- 12
Answer:
a) add x , subtract 1 and divide by 4
The solution of given equation 
<u>Step-by-step explanation:</u>
Given equation 1+3 x = -x +4
<em> Add 'x' on both sides , we get</em>
1 + 3 x + x = - x + x +4
1 + 4 x = 4
<em> Subtract '1' on both sides , we get</em>
<em> 1+4 x -1 = 4 -1</em>
4 x = 3
<em> Dividing '4' on both sides, we get</em>


<u><em>Final answer</em></u>:-
<em>The solution of given equation </em>
<em></em>
