The probability that a randomly selected person at a show has seen the band play live before is 30%. A "superfan" is defined as someone who has seen the band play live at least 10 times. The probability that a person at a show is a "superfan" is 20%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are superfans?
Answer:
0.09 and 0.04
Step-by-step explanation:
The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30
The probability that a person at a show is a "superfan" is 20%=0.20
Two people are selected at random.
The probability that both people have both seen the band perform live before = The probability that the first person has seen the band live before and the second person also has seen the band live before.
=0.30 x 0.30
=0.09
Similarly, the probability that both are "superfans" = The probability that the first person is a superfan and the probability that the second person is a superfan.
=0.20 x 0.20
=0.04
Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

If the selling prices of 20 pens are equal to the cost price of 25 pens, what is the gain percentage?
[tex]\huge\bold\red{Answer:-}[/tex]
No(0)Let the cost price of the 20 pens be ₹100.
Cost of each pen=₹100/20=₹5
Selling price of each 25 pens sold=₹100/25=₹4.
%LOSS:
If cost of each pen. = 5=100%
..selling price of each pen. = 4= ?%.
Cross multiply:5? =400
?=80%
So,%loss= 100%-80%=20%

HELP HELP HELP PLS Does it matter which way you subtract the values when you are finding the distance between two numbers on a number line .Give example to support your answer please answer in complete sentence please it's about to be due.
Answer:
Yes, it matters which way you subtract values because if you subtract a larger number from a smaller number you will get a negative nummber, but when you subtract the smaller number from the bigger number you get a positive number
ex: 5-6= -1 but 6-5=1
Step-by-step explanation:
Reflect: You found that ( 3 + 4 x ) + ( 2 - x ) = 5 + 3x
Suppose x=i (the imaginary unit)
What equation do you get?
Answer must include words/explanations
(guys please help!!)
Answer:
We start with the equation:
(3 + 4x) + (2 -x) = 5 + 3x
Now we replace:
x = i
This is just changing all the "x"s in the equation by "i"s:
(3 + 4i) + (2 - i) = 5 + 3i
This can be viewed as 3 complex numbers:
z1 = 3 + 4i
z2 = 2 - i
z3 = 5 + 3i.
Now, let's check if equality remains true:
(3 + 4i) + (2 - i) = 5 + 3i
The first step is to use the associative and commutative properties to separate the real and imaginary parts.
(3 + 2) + (4i - i)
5 + (4 - 1)*i
5 + 3i
Then the equality remains true.
And this will be true always, for anything that we feed into the x in our initial equation:
(3 + 4x) + (2 -x) = 5 + 3x
This is because x is a variable, so it can be evaluated in any number, and the equality will still be true.

Molly has $45 in her wallet, which is 3 times as much money as her brother has.
Write an equation to represent this situation, where a represents the amount of money Molly’s brother has.
45 =
Answer: 45 divided by 3 equals 15
he has 15 dollars
Step-by-step explanation: 45= 3 times 15
Answer: 45=3a a=15
Step-by-step explanation:
We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

3(x + 3) + 2x + 6 = 45
Solve the equation
Answer:
x = 6
Step-by-step explanation:
3(x + 3) + 2x + 6 = 45
3x + 9 +2x + 6 = 45
5x + 15 = 45
5x = 30
x = 6

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width of one-half millimeter, and height of start fraction 3 over 8 end fraction millimeter. The volume is $$ cubic millimeter.
Answer:
The volume of the rectangular prism is 3/20 (or 0.15) mm³.
Step-by-step explanation:
The volume of the rectangular prism can be calculated as follows:
[tex] V = l*w*h [/tex] (1)
Where:
l: is the length = 4/5 mm
w: is the width = 1/2 mm
h: is the height = 3/8 mm
By entering the values of l, w, and h into equation (1) we can find the volume:
[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]
Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.
I hope it helps you!

Step-by-step explanation:
A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x sodas. (ignore what I wrote already i think it’s wrong)
Answer:
32 + 4x ≤ 50
Step-by-step explanation:
Cost of tickets = $32
Cost of soda = $4
Total spent = $50
When we say "no more than", we mean less than or equal to (≤)
He buys 1 tickets and x sodas
32 + 4x ≤ 50
4x ≤ 50 - 32
4x ≤ 18
Divide both sides by 4
x ≤ 18 / 4
x ≤ 4.5
Shawn can buy more than 4 sodas

Candace is visiting a local water park. The table shows information about the number of hours ( input values) and the total cost (output values)
Can anyone help??
(it’s a timed quiz)
Answer:
B. Domain: {1, 3.5, 5, 7.5, 9}
F. Range: {2, 6.50, 7.00, 9.00, 12.50}
Step-by-step explanation:
The set of input values make up the domain of the function, while the corresponding set of output values is the range of the function.
That is, the domain is the number of hours, while total cost is the total cost.
Domain would be: {1, 3.5, 5, 7.5, 9}
Range would be: {2, 6.50, 7.00, 9.00, 12.50}
The amount of Social Security benefits received by an individual that he or she must include in gross income:
a. May not exceed the portion contributed by the employer.
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
c. May not exceed 50% of the Social Security benefits received.
d. Is computed in the same manner as an annuity [exclusion = (cost/expected return) × amount received].
e. None of these choices are correct.
Answer:
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
Step-by-step explanation:
Social security measures an organization to guarantee individuals against certain risks (social risks). Social security is made up of a set of institutions whose function is to protect individuals from the consequences of various events or situations, generally referred to as social risks.
Social Security is a public service of the State, ensuring all the social risks of workers, employees, liberal professions, self-employed, and non-salaried workers. Social Security provides the benefits provided by the Social Security Code. However, the amount of Social Security benefits received by an individual that they must include in gross income may be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.

$53,000 + 0.8% of 1.2 mill is the answer0.8% = 0.8/100 = 0.0080.008 x 1,200,000 = 9,60053,000 + 9,600 = 62,600.Answer:
9,600

Ok the mistake yall were doing was adding 9,600 with 53,000 when they were asking for the commission so basically plus it says "what is his commission this year?"
.8%
.8 x 100 = .008
1,200,000 x .008 = 9,600
