Find the inverse of the matrix , if it exists
Montano1993 [528]

Answer:

So, option A is correct.

Step-by-step explanation:

To find the inverse of the matrix, the formula is:

A^{-1} = 1/|A| * Adj A

Inverse of the matrix exists if |A| does not equal to 0

|A| = 7 * 9 -( -2 * -10)

|A| = 63 - 20

|A| = 43

AS |A| ≠ 0

so inverse exist.

now finding Adj A

Adj A = \left[\begin{array}{cc}9&2\\10&7\end{array}\right]

\left[\begin{array}{cc}9/43&2/43\\10/43&7/43\end{array}\right]

So, option A is correct.

Suppose that the probabilities of a customer purchasing​ 0, 1, or 2 books at a book store are 0.4​, 0.2​, and 0.4​, respectively
Volgvan

Answer:

Expected number of books = 1.0

Step-by-step explanation:

Expected number of books, E(x) = ∑xp(x)

∑ = Summation

x = books

p(x) = probability of purchasing a book

E(x) = (0*0.4) + (1*0.2) + (2*0.4)

E(x) = 0 + 0.2 + 0.8 = 1.0

Americans eat an average of 100 acres of pizza per year. That is equivalent to 4,356,000 square feet of pizza per year. How is t
Maru [420]

Answer:

D.  4.356 * 10^6 ft²

Step-by-step explanation:

Scientific notation of a number is expressed in the following form, a * 10^b

Where,

a = decimal number (1 ≤ |a| < 10)

b = the power of 10 whereby the scientific notation is equivalent to the original number.

To express 4,356,000 square feet in scientific notation, do the following:

1. Move the decimal point to the left up to the last non-zero digit =  a = 4.356

2. Since we moved the decimal point by 6 decimal places, therefore, b = 6

3. Substitute the values of the variables into  

Thus:

4,356,000 = 3. Substitute the values of the variables into  

a * 10^b

Thus:

4,356,000 = 4.356 * 10^6
