How to subtract the matrices?</h3>
The subtraction of two matrices of the same size is really direct. You just need to subtract the elements that are in the same position, then:
![A = \left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right] \\\\B = \left[\begin{array}{ccc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right]\\\\A - B = \left[\begin{array}{ccc}a_{11} - b_{11}&a_{12}-b_{12}\\a_{21} - b_{21}&a_{22}-b_{22}\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da_%7B11%7D%26a_%7B12%7D%5C%5Ca_%7B21%7D%26a_%7B22%7D%5Cend%7Barray%7D%5Cright%5D%20%5C%5C%5C%5CB%20%3D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Db_%7B11%7D%26b_%7B12%7D%5C%5Cb_%7B21%7D%26b_%7B22%7D%5Cend%7Barray%7D%5Cright%5D%5C%5C%5C%5CA%20-%20B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da_%7B11%7D%20-%20b_%7B11%7D%26a_%7B12%7D-b_%7B12%7D%5C%5Ca_%7B21%7D%20-%20b_%7B21%7D%26a_%7B22%7D-b_%7B22%7D%5Cend%7Barray%7D%5Cright%5D)
Then the missing therm will just be equal to the difference between the last two elements of each matrix:
-2 - (-6) = -2 + 6 = 4
The missing number is 4.

To calculate the area of a circle, use the equation a=pir^2 or area=3.14*radius squared
Insert the known values. We need to find the radius of the circle. Since the radius is half of the diameter, divide the diameter by 2 to get the radius.
The diameter is 20.
20/2=10
Area=3.14*10 squared
Area=3.14*100
Area=314 cm

Answer:
0.06
Step-by-step explanation:
Just type it into your calculator. For me its easier to not try and do it in your head. Plus you'll always have a calculator with you if you have a phone.
Since we are given that the relationship between x and y
is linear. Therefore this means that the given equation takes the form of:
y = m x + b
where,
b is the y intercept of the equation
m is the slope of the equation
However we should take note that the slope m is directly
proportional to the coefficient of correlation. Since our coefficient of
correlation is negative, this only means that the value of y is decreasing with
increasing x, hence plot of y and x is descending with increasing x.
Furthermore, this also tells that for every 1 unit increase of x, there is a
0.75 units decrease of y.
Answer:
Out of the 4 sports only golf does not use a net. Therefore 3/4 is the sports uses a net
The answer is more than 2/4 of the sports
