Answer:

p(F)=0.73

Step-by-step explanation:

we have by identity

p(A\cup B)=p(A)+p(B)-p(A\cap B)

Thus for given events E and F

we havep(E\cup F)=p(E)+p(F)-p(E\cap F)

Applying values we get

p(F)=p(E\cup F)+p(E\cap F)-p(E)

Thus

p(F) = 0.82+0.09-0.18

p(F) = 0.73

What is the equation of a line in general form that does not have a y-intercept and goes through the point (3,6) ?
Dennis_Churaev [7]

Answer:

x = 3

Step-by-step explanation:

<u>Step 1:  Determine the equation</u>

So we know that our equation does not have a y-intercept which means that it doesn't intersect ANYWHERE on the y-axis.  Therefore, this means that our equation will be a straight vertical line that doesn't move side to side and just goes straight up and down.  We also know that our point is (3, 6) which means that our x-value will be 3 and this is where the equation will be located.  

There are several ways to display our answer where x = 3 is the most common way which basically means give me all of the y-values for the same x value of 3.  Another way of saying it is x - 3 = 0 which either way when adding 3 to both sides gives you x = 3 which is what I usually go with.

Answer: x = 3

The volume of the given shape will be equal to V=2827.42 cubic inches.

<h3>What is volume?</h3>

The volume is defined as the space occupied by the object in the three-dimensional plane. It requires three coordinates to find the volume of any object.

Here it is given in the question that:-

Radius of the semicircle=12 inches

Height of the cylinder =13 inches.

Now the volume will be calculated as:-

Total volume of the figure will be the sum of the Volume of the semicircle and the Volume of the cylinder.

= 2πr³+πr²l

= 2xπx(6)³+πx(6)²x13

=1357.16+1470.26

=2827.42  Cubic inches                      

Hence the volume of the given shape will be equal to V=2827.42 cubic inches.
