The expression P(B|C) is an illustration of probability, and the value of P(B|C) is 0.38
How to determine the value of the probability expression?From the question, we have the following highlights:
n(B and C) = 9
n(C) = 24
The equation to calculate the probability expression is:
P(B|C) = n(B and C)/n(C)
Substitute known values
P(B|C) = 9/24
Evaluate the expression
P(B|C) = 0.38
Hence, the value of P(B|C) is 0.38

What is area of rectangle?Area of rectangle is the product of its sides
i.e., Area of rectangle = length x breadth
What is area of circle?The area of a circle is pi times the radius squared (A = π r²).
What is circumference of circle?The circumference of a circle is defined as the linear distance around it.
( C= 2πr)
The can of red bull is in shape of cylinder.
If we open the cylinder it will have two circular surfaces( at bottom and top) and one rectangular sheet.
Like the given figure given.
The can is 6.5 inches tall and has a diameter of about 2.5 inches.
It shows that the two circle will have the diameter 2.5 inches.
d= 2.5 inch
= 0.208 ft
radius, r= [tex]\frac{d}{2}[/tex]
r= [tex]\frac{0.208}{2}[/tex]
r= 0.104 ft
To get the length of the rectangle , we have to calculate the circumference of the circle.Circumference of the circle be,
= 2πr
= 2 x 3.14 x 0.104
= 0.653 ft
The rectangular sheet will have,
length= 0.653 ft, breadth= 6.5 inches = 0.541 ft
Now, area of rectangular sheet be,= length x breadth
= 0.653 x 0.541
=[tex]0.3532 ft^{2}[/tex]
Area of 2 circle( top and bottom of can) be,= 2 x π[tex]r^{2}[/tex]
= 2 x 3.14 x 0.104 x 0.104
= 6.28 x 0.010816
= 0.0679 [tex]ft^{2}[/tex]
Total area of can be,= Area of rectangular sheet + Area of 2 circle( top and bottom of can)
= 0.3532 + 0.0679
= 0.4211 [tex]ft^{2}[/tex]
Now, we have the wall of dimensions
length= 9 ft, breadth= 20 ft
Area of wall be,= length x breadth
=9 x 20
= 180 [tex]ft^{2}[/tex]
Number of cans required to cover the whole wall be,=[tex]\frac{area \;of\; wall}{area \;of\; can}[/tex]

Answer:
Yes it has infinity of solutions.
Step-by-step explanation:
If you plug in certain numbers it will make the statements true.
Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=−6;4x+6y=−12
Step: Solve2x+3y=−6for x:
2x+3y=−6
2x+3y+−3y=−6+−3y(Add -3y to both sides)
2x=−3y−6
2x/2 = −3y−6/2
(Divide both sides by 2)
x= −3/2y−3
Step: Substitute −3/2y−3 for x in 4x+6y=−12:

<A+60=180<A=120°You are asked to create a 5 LETTER password, how many different passwords can you create if.
a) All letters are capitals and repetition is allowed
b) All letters can be either capitals or lower case, but repetition is
not allowed.
Detailed explanations are most welcome.
We will see that the number of different combinations for each case are:
a) 11,881,376b) 311,875,200How many passwords can we make?
We have 5 selections for each password, we need to find the number of options for each one of these selections.
a) Here we can use only capitals an we can repeat, so for each selection (each letter), we have 26 options.
The total number of combinations will be equal to the product between the numbers of options:
C = 26*26*26*26*26 = 11,881,376
b)Now we can use either capitals or lower case, but we can't repeat. (Here I assume that A is different than a, so we can't use A two times, but we could use A and a).
Then we have 26*2 = 52 options.
For the first letter, we have 52 options.
For the second letter, we have 51 options (because one letter was already used).
For the third letter, we have 50 options, and so on.
The total number of combinations will be:
C = 52*51*50*49*48 = 311,875,200

How to calculate the multiples of the number 8?To calculate the multiples of 8 we must multiply 8 by any number and the result will be a multiple of 8.
To identify the multiples of 8 that are between the number 1 and 100, we must multiply the number 8 by the number sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 .

Find the area of the parallelogram please.
Answer: 76.8 mi²
Step-by-step explanation:
The area of a parallelogram can be found be multiplying the base times the height.
A = B * H
A = 9.6 * 8
A = 76.8 mi²
Confused as to why this works? We use the same formula that we do for a rectangle because the "extra triangle" on the left can be moved to fill the empty space on the right. This then gives us a normal rectangle, which allows us to solve for the area
In this question we are provided with the base and height of a parallelogram and we are asked to calculate the area of the parallelogram using the formula.
It is given that the base is 9.6 mi and height is 8 mi.
We know,
[tex] \small\boxed{ \sf {Area_{(parallelogram)} = B × H}}[/tex]
Where,
B stand for BaseH stand for HeightSubstituting the values we get
[tex] \small\sf{ Area_{(parallelogram)} = (9.6 × 8) mi} = 76.8 {mi}^{2} [/tex]
Hence the area of the parallelogram is 76.8 mi².-2-0.5b+12=0.3b+6.2
Step-by-step explanation:
-2 -0.5b + 12 = 0.3b + 6.2
-2 + 12 - 6.2 = 0.3b + 0.5b
3.8 = 0.8b
b = 3.8/0.8
= 4.75
Answer:
4.75
Step-by-step explanation:
-2-0.5b + 12 = 0.3b + 6.2
Move all terms to the left:
-2-0.5b + 12 - (0.3b + 6.2) = 0
Add all the numbers together, and all the variables
-0.5b - (0.3b + 6.2) + 10 = 0
Get rid of parentheses
-0.5b - 0.3b - 6.2 + 10 = 0
Add all the numbers together, and all the variables
-0.8b + 3.8 = 0
Move all terms containing b to the left, all other terms to the right
-0.8b = -3.8
b= -3.8/-0.8
b= 4+0.6/0.8
b= 4.75

The annuity of the monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years is $333.71
What is annuity?An annuity is a series of payments made at equal period of time.
future value = annuity x [(1 + i)ⁿ - 1] / i
annuity = $125.30
i = 1.5% / 12 = 0.00125
n = 35 years x 12 months = 420
future value = $125.30 x [(1 + 0.00125)⁴²⁰ - 1] / 0.00125
future value = $69,156.049 ≈ $69,156.05
annuity = [i x (present value)] / [1 - (1 + i)⁻ⁿ]
i = 1.5% / 12 = 0.00125
n = 20 years x 12 months = 240
present value = $69,156.05
annuity = (0.00125 x $69,156.05) / [1 - (1 + 0.00125)⁻²⁴⁰]
annuity = $86.45 / 0.25904
