1. the total of an area under the curve must be equal to one. 2. Every point of the curve must have an vertical height that is 0 or greater.

Step-by-step explanation:

1. The area under the curve adds up to 1.0, because the sum of probabilities in all situations/events is 1.0.

2. The domain is (-infinity, +infinity). The impossible events are given a probability of zero, if applicable.

Graph the line with the equation

pochemuha

The graph of the linear equation can be seen in the image below.

<h3 /><h3>How to graph the linear equation?</h3>

Here we have the linear equation:

y = (2/5)*x - 6

To graph it, we just need to find two points on the line, and then connect them with a line.

To find the points we just evaluate in two values of x.

if x = 0.

y = (2/5)*0 - 6 = -6

Then we have the point (0, -6)

If x = 5.

y = (2/5)*5 - 6 = 2 - 6 = -4

Then we have the point (5, - 4)

Now we can graph these two points and connect them with a line. The graph of the line can be seen below.

A football coach gives half his players a protein bar to eat before each game; the other players do not receive the protein bar.

timofeeve [1]

To make the sure the results did not happen by chance, the coach can ensure that the protein bars are the only difference between the two groups. For example, he can make sure that both groups are drinking the same amounts of water and getting in the same amount of practice; that way, he will be able to determine that one group is performing better due to the protein bars only. Also, the coach can repeat this experiment multiple times to make sure that the results weren't a random, one-time thing.

The sum of three numbers is 8. twice the smaller is 2 less than the largest, while the sum of the largest and smallest is 5. use

Lorico [155]

X + Y + Z = 8
2x = Z - 2
X + Z = 5
X = 1
1 + Y + Z = 8
Y + Z = 6
1 + Z = 5
Z = 4
1 + Y + 4 = 8
5 + Y = 8
Y = 3
The variables are 1, 3, 4.

F(x) = -3x+17 and g(x) = x^2 -6 find g(5)-f(5)

aniked [119]

Answer:

For the given functions, the value of g(5)-f(5) = 17

Step-by-step explanation:

Here, the given functions are:

f(x) = -3x + 17

$g(x) = x ^2 - 6$

So, f(5) = -3(5) + 17

= -15 + 17 = 2

And $g(5) = (5)^2 - 6 = 25 - 6 = 19$

So, f(5) = 2 and g(5) = 19

⇒g(5) - f(5) = 19 - 2 = 17

Hence, for the given functions, the value of g(5)-f(5) = 17
