Answer:

y = 3/4x + 3

Step-by-step explanation:

you should only have y in one side and everything in other side of the equation. so you will first have -4y = -3x -12 , then you'll have to divide the right part of the equation by -4 . then you will have y = 3/4x + 3

What equation does the model represent?

Vesnalui [34]

It would be 62+23=94 because you'll need to add the tens and the ones, then add it up

What is the range of the function in the graph below(photo imported)

olga55 [171]

Answer: y is less than or equal to -1

How?

The graphs highest value it will ever reach, range wise, is -1. Therefore it isnt 0, or all real numbers.

The reason why it is -1 and not -2 is because the curve hits -1. Sure, -2 is included in the range, but y is less than or equal to -1 INCLUDES -2

A survey was conducted about the colors of shoes that people

alex41 [277]

Answer:

Option B) 0.797

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

step 1

Find the probability that a randomly selected person was female

In this problem we have

$x=33$ ----> total females

$y=31+33=64$ ---> total males plus total females

substitute

$P=\frac{33}{64}$

step 2

Find the probability that a randomly selected person was was wearing brown shoes

In this problem we have

$x=18$ ----> total brown shoes

$y=64$ ---> total shoes

substitute

$P=\frac{18}{64}$

step 3

Find the probability that a randomly selected person was either female or was wearing brown shoes

Adds the probabilities

$P=\frac{33}{64}+\frac{18}{64}=\frac{51}{64}=0.797$
