Mathematics
1 answer:
Cloud [144]3 years ago
7 0

Answer:

The curve is on or above the horizontal axis ⇒ 1st

The total area under the curve is 1 ⇒ 2nd

The proportion of data values between two numbers and is the area

under the curve between a and b ⇒ 4th

Step-by-step explanation:

* Lets explain the meaning of density curve

- Density curve  is a mathematical model for a distribution of a variable

- It is another type of graph that represents a quantitative variables

- It describes the overall pattern of a distribution

- <u><em>Its area is always on or above the horizontal axis</em></u>

- <u><em>Its area under the curve is exactly 1</em></u>

- It can come in many shapes - symmetric, right-skewed, left-skewed

- <u><em>The area under the curve and above any range of values on the </em></u>

  <u><em>horizontal axis is the proportion of all observations that fall in</em></u>

  <u><em>that range</em></u>

- Ex: density curve describes the probability distribution of a

 continuous random variable

 The probability of any event is the area under the curve and above

 the values that make up the event.

* Now lets chose the true statements

# <u><em>The curve is on or above the horizontal axis</em></u>

# <u><em>The total area under the curve is 1</em></u>

# <u><em>The proportion of data values between two numbers and is the area</em></u>

  <u><em>under the curve between a and b</em></u>

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop?
konstantin123 [22]

Answer:

Coffee(time)

Step-by-step explanation:

A function's output variable will be:

output(input)

So we need to find the input variable and the output variable.

We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.

The time of day then becomes our input as the coffee sold relies on that number.

That leaves coffee sold as our output!

So the best name for a function in this scenario is Coffee(time).

Hope this helped!

Center: (2,8), Radius: 3
Rzqust [24]

Answer:

I’m not sure what this question is asking, but I’ll write an equation of this circle you are describing. Here, the x coordinate of the center is h, the y coordinate is k, and radius is r in the equation : (x-h)^2+(y-k)^2=r^2, meaning the equation in this situation is the following: (x-2)^2+(y-8)^2=9

How do I solve : COT pi/4 ...?
Wewaii [24]
Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
