Answer: The second matrix
If we want to write a proper matrix to represent the given system of equations, we have to arrange it in order:
After this, we can write the matrix with the coefficients of each equation:
![\left[\begin{array}{ccc|c}1&1&1&180\\2&-1&0&0\\4&0&-1&-5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Cc%7D1%261%261%26180%5C%5C2%26-1%260%260%5C%5C4%260%26-1%26-5%5Cend%7Barray%7D%5Cright%5D)
Being this, the matrix that represents the measure of each angle in Ming's triangle
Answer:
0.5375
Step-by-step explanation:
The point estimate of proportion of all Americans who are in favor of outlawing cheese can be computed as
p=x/n
Here. x is the number of favorable outcomes and n is sample size.
We are given that x=2150 and n=4000, So,
p=2150/4000
p=0.5375.
Thus, the point estimate of proportion of all Americans who are in favor of outlawing cheese is 0.5375.
Step-by-step explanation:
soo here is the answer
170 degree is the value of =x
and the value of uly is 110 degree
Answer:
answer 3:
They are proportion so just put equal sign and see if hey make sense.
Or you can realize that longer side of tringle for the 2 trangles are 10 and 5 and shorter side of triangle are 5 and 2.5 respectively
To find the decimal you divide the number on the top of the fraction by the number on the bottom of the fraction. so...:
258/300=0.86
now, to find the percent, you simply convert the decimal:
0.86 represents 86 hundredths (which is the second place after the decimal point)
which can also be stated at 86%
