Answer:

a = -21 and b = 15

Step-by-step explanation:

It is given a matrix multiplication,

<u>To find the value of a and b </u>

It is given that,

| 6 -5 | * | -1 | = | a |

|-3 4 | | 3 | | b |

We can write,

a = (6 * -1) + (-5 * 3)

= -6 + -15

= -2 1

b = (-3 * -1) + (4 * 3)

= 3 + 12

= 215

Therefore the value of a = -21 and b = 15

Actually, the domain is the possible set of input values of a function that will make the function fit the specific criteria. In this case, the input value is m, where m is the number of miles that is travelled. The criteria is to travel at least 10 miles but not more than 30 miles, therefore the domain should be:

All real numbers from 10 to 30, inclusive

(should be real numbers not integer since any fractional number is included in the domain)

I cannot figure out why the choices are far from the answer.

A group of 5 men are meeting for lunch.

Sladkaya [172]

Tile:

<h2>See the explanation.</h2>

Step-by-step explanation:

(a)

There were total 5 men wearing coats.

5 coats can be returned to 5 men in 5! = 120 ways.

The coats can be returned to the accurate persons only in 1 way.

Hence, the probability that each man gets the correct coat is $\frac{1}{120}$ .

(b)

At the time of returning the first coat, the hostess will have 5 choices and for the second she will have 4 choices.

Hence, in $5\times4 = 20$ ways the hostess can return the 2 coats.

There is only 1 possible case that each of the coats will return to the correct owner.

Hence, the required probability is $\frac{1}{20}$ .
