The relationship between numbers in list X and list Y follows the rule Y = X +2.05 what diagram shows this relationship
dexar [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=x+2.05

This is a linear equation ( equation of a line)

To graph the line find the intercepts

<u>The y-intercept</u> is the value of y when the value of x is equal to zero

For x=0

y=0+2.05=2.5

The y-intercept is the point (0,2.05)

<u>The x-intercept</u> is the value of x when the value of y is equal to zero

For y=0

0=x+2.05

x=-2.05

The x-intercept is the point (-2.05,0)

To graph the line plot the intercepts and then join the points

using  graphing tool

see the attached figure

Assume that we have two events, and , that are mutually exclusive. Assume further that we know and . If an amount is zero, enter
sweet [91]

Answer:

Explained below.

Step-by-step explanation:

The complete question is:

Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.30 and P(B) =0.40.

What is P(A and B)?

What is P(A | B)?

Is P(A | B) equal to P(A)?

Are events A and B dependent or independent?

A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent. Is this statement accurate?

What general conclusion would you make about mutually exclusive and independent events given the results of this problem?

Solution:

The probability of the two events <em>A</em> and <em>B</em> are:

P(A) = 0.30 and P(B) =0.40

(a)

Compute the value of P (A ∩ B) as follows:

P(A\cap B)=0

This is because mutually exclusive events are those events that cannot occur together.

(b)

Compute the value of P (A | B) as follows:

P(A|B)=\frac{P(A\cap B)}{P(B)}=\frac{0}{0.40}=0

Thus, the value of P (A | B) is 0.

(c)

No, P (A | B) is not equal to the P (A).

(d)

As mentioned in part (a), mutually exclusive events are those events which cannot occur together.

That is, P(A\cap B)=0.

Events A and B are independent  if the chance of their concurrent happening is equivalent to the multiplication of their distinct probabilities.

That is, P(A\cap B)=P(A)\times P(B).

The concepts of mutually exclusive events and independent events are not the same.

(e)

As the it is provided that A and B are mutually exclusive events, we know that P(A\cap B)=0.

Now compute the value of P(A)\times P(B) as follows:

               P(A)\times P(B)=0.30\times 0.40=0.12\neq 0

Thus, the events A and B are not independent.

Thus, if two events are mutually exclusive events they cannot be independent.

Determine the angle at the centre of a circle with radius 6.0 cm for an arc length of 8.0 cm.
sveta [45]

Answer:

Third option.

Step-by-step explanation:

You need to remember that the formula used to calculate the arc lenght is:

arc\ length=r C

Where "r" is the radius and "C" is the central angle in radians.

You need to solve for "C":

C=\frac{arc\ length}{r}

You know the radius and the arc lenght, therefore, you can substitute values to calculate the central angle in radians. Therefore, this is:

C=\frac{8.0cm}{6.0cm}

C=\frac{4}{3}radians
