which of these is an example of a discrete random variable 1) hours worked at job, weight of a child, number of siblings, length

lozanna [386]

Answer:

hours worked at job, number of siblings are examples of discrete random variable.

Step-by-step explanation:

Discrete random variable has values that can be counted. It has finite data that does not change continuously.

Hours worked at a job can be counted at the end of the day.

The weight of a child keeps changing continuously therefore it is not a discrete random variable.

Number of siblings can be counted.

The length of a fish can keep changing day by day therefore it is not a discrete random variable.

Decide whether the relation defines a function.

diamong [38]

Answer:

Step-by-step explanation:

Lets first solve the relation for "y". Shown below:

$3x=9-4y\\4y=-3x+9\\y=-\frac{3}{4}x+\frac{9}{4}$

This is clearly an equation of a line in the form $y=mx+c$

It will be a negatively sloped line, when graphed.

We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.

Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.

So, this is definitely an equation of a function

Correct answer is A

Answer:

<h2>120 Pennies</h2>

Step-by-step explanation:

First, we need to find 80% of 400

400 x 0.8 = 320

Now 50% of 400 is 200

320 - 200 = 120

The graph of an arithmetic sequence is shown.

GalinKa [24]

Answer:

The fifth term is 7

Step-by-step explanation:

Looking at the graph

we have the ordered pairs

(1,5),(2,5.5),(3,6),(4,6.5),(5,7)

Let

$a_1=5\\a_2=5.5\\a_3=6\\a_4=6.6\\a_5=7$

The common difference in this arithmetic sequence is 0.5

The value of the fifth term is a_5

therefore

The fifth term is 7
