Answer: Choice D

The graph will be discrete because there is no such thing as a partial person to sign up, and the booth is set up once each day for sign ups.

=========================================================

Explanation:

Let's start with the independent variable d. This acts as the variable x. It's the input. The value of d only takes on positive whole numbers (eg: d = 1, d = 2, d = 3, etc). We cannot have something like d = 2.718

So this bit of evidence shows that our function is discrete. Discrete input values (d) plug into the function to produce corresponding discrete output values (m).

Furthermore, we know that m is discrete because the number of people cannot be a fractional or decimal number. We can't have half a person for instance.

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

A quick way to see if a set is discrete or continuous is to ask the question: "is it possible to apply the midpoint formula for ANY two values, and have the output make sense?"

So a set like {1,2,3,4,5,...} is discrete because the midpoint of 2 and 3 is 2.5, but that value is not in the set mentioned.

In other words, discrete sets have "gaps" so to speak, while continuous ones do not.

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

Another useful property is that let's say that a < x < b, and x is drawn from the domain set. This reduced set will be finite if we're dealing with discrete data. Eg: The set {1,2,3,4,5,...} has the subset {2,3,4} which is finite and discrete.

In contrast, the subset of real numbers x such that 2 \le x \le 4 is continuous and this subset is infinitely large (has infinitely many members) because we could have things like 2.718 or 3.14 etc

Help this will save my grade. I’m right on the edge of failing!
8090 [49]

Answer:

Step-by-step explanation:

1.  The slope is -5/2

2. There is no slope for the second one it's just y=3

3. The slope is 3

4. These are perpendicular lines

5. These lines are parallel.

6. These lines are neither perpendicular nor parallel.

7. These lines are perpendicular

8.  y = 4/3x - 2

9.  y = -1/2x + 5

10. x = -1  

Hope this helps!

The average speed of one team in a relay race is about 10 miles per hour. What is the speed in feet per second?
ki77a [65]

10 miles per second in feet per second is 14.67 feet per second

Step-by-step explanation:

The average speed of one team in a relay race = 10 miles per hour.

We need to find the speed in feet per second.

  • The conversion rule is:

             1 mile per hour = 1.467 feet per second

So, Speed in feet per second is:

 1 mile per hour = 1.467 feet per second

10 miles per hour = 10*1.467 feet per second

                             = 14.67 feet per second

So, 10 miles per second in feet per second is 14.67 feet per second

Allan drew a polygon with 4 sides and 4 angles. All four sides are equal. None of the angles are right angles. What figure did A
Lady_Fox [76]

Answer: The figure drawn by Alan is a rhombus.


Step-by-step explanation:

Given: Allan drew a polygon with 4 sides and 4 angles with two properties:-

  • All four sides are equal.
  • None of the angles are right angles.

We know that only a rhombus is a flat shape with 4 equal straight sides and 4 angles .All sides have equal length. Its angles need not to be right angle.

Therefore, the figure drawn by Alan is a rhombus.

Marcus needs to bike at least 80 mi this week for a training if he has already bike 25 mi this week then how many miles should h
Rashid [163]

Marcus needs to bike at least 11 miles each day.

Step-by-step explanation:

Given,

Distance to cover = 80 miles at least

Distance already biked = 25 miles

Number of days left = 5

Let,

x be the distance to cover in 5 days.

According to given statement;

Number of days left * Distance to cover + distance already bike ≥ Total distance to travel

5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55

Dividing both sides by 5

\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11

Marcus needs to bike at least 11 miles each day.
