Answer:

f^-1(x) = 4x-3

Step-by-step explanation:

f(x) = (x+3)/4

y = (x+3)/4

Exchange x and y

x = (y+3)/4

Solve for y

4x = y+3

Subtract 3

4x-3 = y

The inverse

f^-1(x) = 4x-3

to go to the dog beach, it costs $3 plus $2 per dog. write an equation that shows this situation, where "x" represents the numbe

bixtya [17]

The equation representing this situation would be 3 + 2x = c, where c is the total cost.

To find the cost to bring 12 dogs, you will replace the x with the number 12.

3 + 2 x 12 = 27

The cost would be $27.

Determine whether each expression represents the statement divide the sum 15 and 6 by the difference of 10 and 3.

iris [78.8K]

Answer:

$\frac{15+6}{10-3}$

Step-by-step explanation:

Sum of 15 and 6 = 15 + 6

Difference of 10 and 3 = 10 - 3

So, the expression is

$\frac {15 + 6}{10-3}$

This is the required expression.

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.

Lyrx [107]

It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:

c) Since the sum of the probabilities is not equal to 1.

-----------------------------------------

For the sequence $(x, P(X = x))$ representing a probability distribution, it is needed that:

All probabilities are between 0 and 1, that is, for all values of x, $0 \leq P(X = x) \leq 1$ .
The sum of all probabilities is 1, that is: $\sum_{i = 1}^n P(x_i) = 1$
