E and F are two events and that P(E)=0.2 and P(F/E)=0.6 what is P(E and F)

AVprozaik [17]

The probability of E and F expressed as P(E and F) equals;0.12

<h3>How to solve Conditional Probability?</h3>

We are given;

P(E) = 0.2

P(F|E) = 0.6

Now, P(F/E) is known as conditional probability and it means the probability of event F given the probability of another event E. This can be expressed as; P(F|E) = P(E and F)/P(E)

Thus;

P(E and F) = 0.2 * 0.6

P(E and F) = 0.12

The total width of two standard shortboards

sergey [27]

Answer:

2s + t = 23.5

Step-by-step explanation:

There are two types of shortboards:

standard

technical

Let the width of a standard shortboard be represented by s.

Similarly, Let the width of a technical shortboard be represented by t.

As per the given information: total width of two standard shortboards

and a technical shortboard is 23.5 inches.

Representing it as an equation in terms of the variables defined:

2s + t = 23.5

5. What is the y-intercept of the line of best fit?

Verizon [17]

6. The y-intercept is 8

7. the slope is -1/2

8. Equation of line is: $y = -\frac{1}{2}x+8$

Step-by-step explanation:

Let us define y-intercept first

The y-intercept of the line is where the line intersects the y-axis.

<u>5. What is the y-intercept of the line of best fit?</u>

The given line on graph intersects the y-axis on 8 so the y intercept of the line of best fit is 8

<u>6. What is the slope of the line of best fit for this scatter plot?</u>

The slope can be calculated by locating two points on line.

In the given line, we can easily observe two points

(2,7) and (4,6)

The slope is calculated by the formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Here (x1, y1) are the coordinates of first point on line and (x2,y2) are the coordinated of second point on line

So, putting the values

$m=\frac{6-7}{4-2}\\=\frac{-1}{2}\\=-\frac{1}{2}$

<u>7. What is the equation of the line of best fit?</u>

The slope intercept form of any line is given by:

$y=mx+b$

where m is slope and b is y-intercept of the line

As we already know

m = -1/2 and y-intercept is 8

Putting the values in the equation

$y = -\frac{1}{2}x+8$
