$8.88
Step-by-step explanation:
12.00 - 26%(3.12)= $8.88
The question is incomplete. The complete question is as follows:
Solve for X. Assume X is a 2x2 matrix and I denotes the 2x2 identity matrix. Do not use decimal numbers in your answer. If there are fractions, leave them unevaluated.
· X· =<em>I</em>.
First, we have to identify the matrix <em>I. </em>As it was said, the matrix is the identiy matrix, which means
<em>I</em> =
So, · X· =
Isolating the X, we have
X·= -
Resolving:
X·=
X·=
Now, we have a problem similar to A.X=B. To solve it and because we don't divide matrices, we do X=A⁻¹·B. In this case,
X=⁻¹·
Now, a matrix with index -1 is called Inverse Matrix and is calculated as: A . A⁻¹ = I.
So,
·=
9a - 3b = 1
7a - 6b = 0
9c - 3d = 0
7c - 6d = 1
Resolving these equations, we have a=; b=; c= and d=. Substituting:
X= ·
Multiplying the matrices, we have
X=
You would divide 44 by 16 so the wing span is 2.75 ft.
What is the third quartile of the data set? 23, 35, 55, 61, 64, 67, 68, 71, 75, 94, 99

Answer:
he multiplied by 0.8 not .08
Step-by-step explanation:
when doing 8% you go back 2 places so 0.08
34×0.08= 2.72
34+2.72= 36.72
