Answer:
the probability is:
P(A) 2/6 =1/3
Now let's take rolling a prime number:
A prime number is a natural number greater than 1 which can only be divided without a remainder by 1 and itself. So from the numbers on the cube prime numbers are:
2, 3 and 5. The probability of getting a prime number in a single roll is:
P(B) =3/6=1/2
Now to calculate the probability of A and B
you have to multiply both probabilities:
P(A-B)=P(A) . P(B) = 1/3 . 1/2 = 1/6

A basketball player completed 44.2% of his field goals in the most recent season. He made 287 field goals. How many did he attempt?
44.2%= 287
Let the total attempt = x
(287/x) ×100 = 44.2
287/x = 44.2/100
287/x = 0.442
x = 287/0.442

7. Cho Sasaki demonstrates microwave ovens at the National Home Show. She is
paid $7 each for the first 7 demonstrations and $11 for each demonstration over 7.
What is her commission for a day in which she makes 12 demonstrations
Answer:
The commission made is $104
Step-by-step explanation:
Here, given the payment analysis, we want to know the total pay for a day in which 12 demonstrations were made.
From the question, we can deduce the following;
For the first 7 demonstrations , $7 is paid
Now for the remaining 5 out of the total 12, the amount paid per demonstration is $11
So the total commission earned will be;
$7(7) + $11(5)
= $49 + $55 = $104

Peyton received a $5,000 bonus at work, and plans to invest it today. Her investment account will earn a 5% interest rate, compounded monthly. What will her account value be in 20 years? Peyton will have $___ in the account after 20 years.
Answer:
$ 13,563.20
Step-by-step explanation:
Formula for total amount accrued or gathered after interest is compounded monthly = A = P(1 + r/n)^nt
A = Amount after t years
P = Initial amount Invested = $5,000
r = Interest rate = 5% = 0.05
n = compounding frequency = Every month = 12
t = time in years = 20
A = $5000(1 + 0.05/12)^20 × 12
A = $ 13,563.20
Therefore, Peyton will have $13,563.20 in the account after 20 years.
Answer:
FV = PV (1 + )nt
PV = $5,000
r = 0.05
n = 12
t = 20
FV = 5,000 (1 + )12 · 20
= 13,563

whats the product of 0.02 x0.3?PLEASE ANSWER WITH STEPS PLEASEEEE,ITS URGENT
Answer:
0.006
Step-by-step explanation:
This is the answer because:
Short Way:
1) We know 3 x 2 is 6
2) When we multiply with zeros, how many ever zeros there are in the factors together, should be in the answer. In this case, in the answer we should have 3 zeros, one before the decimal point and two after the decimal point, because in 0.02 there are two zeros while in 0.3 there is only one zero.
3) Finally, the answer would be 0.006
Long Way:
1) You can do long multiplication to solve for the answer.
2) 0.02
× 0.3
Is 0.006 because 3 x 2 is 6, and then 3 x 0 is 0 and then 3 x 0 is 0.

If a club charges dues of $200 a year, it will have 50 members. For each $5 it raises its dues, it loses a member. USE AN EQUATION to determine what the club should charge to maximize its income from dues.
Answer:
The value is [tex]y = \$ 225[/tex]
Step-by-step explanation:
From the question we are told that
The amount charge per year is [tex]k = \$ 200[/tex]
The number of members it will have at this amount is [tex]n = 50[/tex]
The amount amount increase that will lead to the loss of a single member is [tex]z = \$ 5[/tex]
Generally the total amount the club would obtain from its members is mathematically represented as
[tex]I = Amount \ due\ paid * Number \ of members[/tex]
Now let x denote the number of member lost
Hence
[tex]I = (k + zx) (n-x )[/tex]
=> [tex]I = (200 + 5x) (50-x )[/tex]
=> [tex]I = 10000+50x-5x^2[/tex]
Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero
[tex]\frac{dI}{dx} = 50-10x[/tex]
=> [tex] x = 5[/tex]
So from [tex]I = (200 + 5x) (50-x )[/tex] we have
[tex]I = (200 + 5 (5)) (50-5 )[/tex]
[tex]I = \$ 10125 [/tex]
So the amount the club should charge is
[tex]y = \frac{10125}{50 - 5}[/tex]
[tex]y = \$ 225[/tex]
A king and his army will attempt to capture a fortress. The left and right flanks break off from the main group to attack the west and east guard towers. Suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. If both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort. If, however, only the left flank captures its tower, the king has an 80% chance of success; if only the right flank succeeds, the king has a 50% chance. If both flanks fail, then the king's chance of capturing the fort drops to 20%. What is the chance the king will capture the fort
Answer:
Step-by-step explanation:
Let the probability of winning from left side be L and from right side by R .
Let the probability of winning by king be K .
Given information can be summarised as follows :
P(L) = .6
P(R) = .75
P K/(L∩R)=.98
P K/(L∩R')= .8
P K/(L'∩R) = .5
P K/(L∩R)' = .2
Probability of win by King can be summarised as follows .
P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'
P(L∩R) = .6 X .75 = .45
P(L∪R) = P(L) +P(R) - P(L∩R)
= .6 +.75 - .45 = .90
P(L∪R)' = 1 - P(L∪R) = .10
P(L∩R') = P(L) - P(L∩R) = .6 - .45 = .15
P(L'∩R) = P(R) - P(L∩R) = .75 - .45 = .30
P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'
= .45 x .98 + .15 x .8 + .30 x .5 + .1 x .2
= .441 + .12 + .15 + .02
= .73 approx .

Which of the following ordered pairs belongs to the graph of f(x)
- 3x + 9?
O (1, – 10)
O (-1, 12)
O (2, – 3)
O (-2, 13)
Answer:
The second choice, [tex](-1,\, 12)[/tex].
Step-by-step explanation:
Note, that the expression [tex]y = f(x)[/tex] is an equation. A point [tex](x,\, y)[/tex] is on the graph of [tex]y = f(x)\![/tex] if and only if the value of [tex]x[/tex] and [tex]y[/tex] satisfy this equation; that is: in other words, the [tex]y\![/tex]-coordinate of that point (the second number in the tuple) should be equal to [tex]f(x)[/tex], which is equal to [tex](-3\, x +9)[/tex] (evaluated where [tex]x\![/tex] is equal to the first number in the tuple.
For each tuple in the choices, calculate the value of [tex]f(x)[/tex] where [tex]x[/tex] is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on [tex]y = f(x)[/tex] only if these two numbers match.
First choice: [tex]x = 1[/tex], [tex]f(x) = f(1) = -3 + 9 = 6[/tex]. That's not the same as the second number, [tex]-10[/tex]. Therefore, this point isn't on the graph of [tex]y = f(x)[/tex].Second choice: [tex]x = -1[/tex], [tex]f(x) = f(-1) = (-3)\times (-1) + 9 = 3 + 9 = 12[/tex]. That matches the second number in the tuple. Therefore, this point is on the graph of [tex]y = f(x)[/tex].Third choice: [tex]x = 2[/tex], [tex]f(x) = f(2) = (-3)\times 2 + 9 = 3[/tex]. That's not the same as the second number, [tex](-3)[/tex]. Therefore, this point isn't on the graph of [tex]y = f(x)[/tex].Fourth choice: [tex]x = -2[/tex], [tex]f(x) = f(-2) = (-3)\times (-2) + 9 = 15[/tex]. That's not the same as the second number, [tex]13[/tex]. Therefore, this point isn't on the graph of [tex]y = f(x)[/tex].2+99999999-7+638378892=?

Three messenger services deliver to a small town in Oregon. Service A has 60% of all the scheduled deliveries, service B has 30%, and service C has the remaining 10%. Their on-time rates are 80%, 60%, and 40% respectively. a. What proportion of the packages in the town are delivered on time
Answer:
Proportion of total delivered on time is 70% or 7/10
Step-by-step explanation:
Here, we want to know the proportion of all the packages delivered on time.
Moving away from the percentage, let’s say the total produced package amongst the 3 is 100
So;
Service A has 60% which is 60
Service B has 30% which is 30
Service C has 10% which is 10
Now from here, we move as follows;
on time rate for service A is 80%
This means 80/100 of the 60 is delivered on time
That will be 80/100 * 60 = 48
For service B, 60% is delivered on time; Thus we have ;
60/100 * 30 = 1800/100 = 18
For service C , 40% of 10
40/100 * 10 = 4
So the total on time delivery will be;
18 + 4+ 48 = 70
So the proportion delivered on time will be 70/100 = 7/10 or 70%
