Mathematics

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality. First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4. Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly trav

ivann1987 [24]

Answer:

<h2>The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.</h2>

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20$

Therefore, the equation is $y=20x$ , which shows a direct proportion between variables.

Now, in 24 hours, it would travel

$y=20(24)=480$

It would travel 480 miles.

Therefore, the right answer is the second choice.

In a given year there is a 3% chance you will get in a small accident costing around $2000 and 0.1% chance you will get in a maj

Wittaler [7]

Answer:

$475

Step-by-step explanation:

There are 3 possible accident in this question

3% chance of losing $2000

0.1% chance of losing $150,000

96.9% chance of losing $0

Then the expected value that you will lose is:

3%* $2000 + (0.1% * $15000) + (96.9% * $0)= $75

Profit made by subtracting the price with the lose. If the company want average profit $400, the charge should be:

average profit = premium price - average lose

premium price= average profit + average lose

premium price= $400 + $75 = $475

Identify all sets to which each number belongs.

gregori [183]

Answer:

14 is a positive integer, then it belongs to the set of natural numbers.

1 and 5/9 are rational numbers. The second is already a fraction and the first one, 1, is a natural number, but all the natural numbers can be written as the result of a fraction. For example: 1=6/6.

About the last number, I don't know if it's written correctly. That should be pi maybe, that is 3.14159.... In that case it's an irrational number.

Irrational numbers are all those real numbers that are not rational.

In general you have that:

ℕ ⊂ ℤ ⊂ ℚ ⊂ ℝ

ℕ. Natural numbers. It's the "smallest" one.

ℤ. Integers. Made with positive and negative natural numbers. Includes the natural numbers then.

ℚ. Rational numbers. Everything that can be written as a fraction. Includes both ℕ and ℤ.

ℝ. Real numbers. Any kind of number, fraction or not.
