What are the values of m and n in the matrix addition below?

Aleksandr [31]

ANSWER

The correct answer is $m=45,n=12$ .

EXPLANATION

We were given the matrix equation;

$\left[\begin{array}{cc}n-1&6\\-19&m+3\end{array}\right] +\left[\begin{array}{cc}-1&0\\16&-8\end{array}\right] =\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

We must first simplify the Left Hand Side of the equation by adding corresponding entries.

$\left[\begin{array}{cc}n-1+-1&6+0\\-19+16&m+3-8\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

That is;

$\left[\begin{array}{cc}n-2&6\\-3&m-5\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right]$ .

Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.

This implies that;

$n-2=10$

We got this equation from row one-column one entry of both matrices.

$n=12$

Also, the row three-column three entries of both matrices will give us the equation;

$m-5=40$

$m=45$

Hence the correct answer is $m=45,n=12$ .

The correct option is option 2

Select the correct answer. This table shows information on types of fragrances sold to men and women in a day at a beauty supply

maria [59]

Answer: C. 27% of men like woody fragrances, and 45% of the people who like citrus fragrances are women

Step-by-step explanation:

Here, Given table,

Citrus Fruity Woody

Men : 27 21 18

Women : 22 26 15

Thus, The percentage of men like woody fragrances

= $\frac{\text{Number of men who like woody fragrance}}{\text{total number of Men}} \times 100$

= $\frac{18}{66}\times 100$

= $\frac{1800}{66}$

= 27.2727..... %

≈ 27 %

Now, The percentage of men like woody fragrances

= $\frac{\text{Number of women who like citrus fragrance}}{\text{total number of persons who like citrus}} \times 100$

= $\frac{22}{49}\times 100$

= $\frac{2200}{49}$

= 44.8979591837 %

≈ 45 %

Thus, Option C is correct.
