Answer:
The answer is 51,200 in².
Step-by-step explanation:
(4x40)x(8x40)=51,200
Angles<span> can be either straight, right, acute or obtuse. An angle</span><span> is a fraction of a circle where the whole circle is 360°. A straight </span>angle<span> is the same as half the circle and is 180° whereas a right </span>angle<span> is a quarter of a circle and is 90°

Answer:
a)
b) r =-0.932
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained by the linear model is 86.87%.
Step-by-step explanation:
Assuming the following dataset:
Monthly Sales (Y) Interest Rate (X)
22 9.2
20 7.6
10 10.4
45 5.3
Part a
And we want a linear model on this way y=mx+b, where m represent the slope and b the intercept. In order to find the slope we have this formula:
Where:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Part b
For this case we need to calculate the correlation coefficient given by:
So then the correlation coefficient would be r =-0.932
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained by the linear model is 86.87%.

Answer:</h2>
<u>The length is</u><u> 12 feet</u>
<h2>
Step-by-step explanation:</h2>
The width of the garden is 5 feet
After that the total edging is telling us the area
We know that
<h3>Area of rectangle = length x width</h3>
So
60 = length x 5
Length = 60 / 5
Length = 12 feet
1km is 1000 m
1000m+125m-375m=750m
