Answer:
The correct answer has already been given (twice). I'd like to present two solutions that expand on (and explain more completely) the reasoning of the ones already given.
One is using the hypergeometric distribution, which is meant exactly for the type of problem you describe (sampling without replacement):
P(X=k)=(Kk)(N−Kn−k)(Nn)
where N is the total number of cards in the deck, K is the total number of ace cards in the deck, k is the number of ace cards you intend to select, and n is the number of cards overall that you intend to select.
P(X=2)=(42)(480)(522)
P(X=2)=61326=1221
In essence, this would give you the number of possible combinations of drawing two of the four ace cards in the deck (6, already enumerated by Ravish) over the number of possible combinations of drawing any two cards out of the 52 in the deck (1326). This is the way Ravish chose to solve the problem.
Another way is using simple probabilities and combinations:
P(X=2)=(4C1∗152)∗(3C1∗151)
P(X=2)=452∗351=1221
The chance of picking an ace for the first time (same as the chance of picking any card for the first time) is 1/52, multiplied by the number of ways you can pick one of the four aces in the deck, 4C1. This probability is multiplied by the probability of picking a card for the second time (1/51) times the number of ways to get one of the three remaining aces (3C1). This is the way Larry chose to solve the this.

Step-by-step explanation:
A standard deck of cards is made up of 52 cards.
There are 4 kings in a deck.
4/52
Bob has a 4/52 chance of picking a king.
I don't know if the cards he picked prior to this he put back or not. If he didn't then it's 3/48.

In ΔABC, AD and BE are the angle bisectors of ∠A and ∠B and DE ║ AB . If m∠ADE is with 34° smaller than m∠CAB, find the measures of the angles of ΔADE.
To find the measures of the angles in ΔADE, we can apply the angle bisector theorem and the fact that DE is parallel to AB. The measures of ∠ADE, ∠AED, and ∠DAE are denoted as x, y, and z, respectively.
Explanation:In ΔADE, we know that AD is the angle bisector of ∠A and BE is the angle bisector of ∠B. We also know that DE is parallel to AB. Given that m∠ADE is 34° smaller than m∠CAB, we need to find the measures of the angles in ΔADE.
Let's denote the measures of ∠ADE, ∠AED, and ∠DAE as x, y, and z, respectively.
From the angle bisector theorem, we know that ∠CAD = ∠DAB = y+z.
Since DE is parallel to AB, we have ∠ADE = ∠CAB = x+y+z.
Therefore, the measures of the angles in ΔADE are ∠ADE = x, ∠AED = y, and ∠DAE = z.

How many different ways can the first 12 letters of the alphabet be arranged?
There are 479001600 different ways the first 12 letters of the alphabet can be arranged.
The first 12 letters of the alphabet can be arranged in 479,001,600 different ways.
The question asks how many different ways the first 12 letters of the alphabet can be arranged. This type of problem is addressed by using permutations, which is a concept in combinatorics, a branch of mathematics. When we talk about arranging a set of items, we are often dealing with permutations.
The formula to determine the number of permutations of a set of n distinct objects is given by n!, which is read as 'n factorial'. The factorial of a number n is the product of all positive integers less than or equal to n.
So, for the first 12 letters of the alphabet, which are 'A, B, C, D, E, F, G, H, I, J, K, L', the number of different ways to arrange these letters would be:
12! (12 factorial)
To calculate 12!, you multiply all the whole numbers from 1 to 12 together:
12! = 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 479,001,600

The graphic shows the schedule network diagram (in minutes) for assembling a toy train set. What is the duration of the critical path?
A) 38 minutes
B) 41 minutes
C) 49 minutes
D) 51 minutes
The critical path in a project schedule is the longest sequence of tasks from start to finish and determines the minimum total duration for the project. Without the diagram, the correct duration from your multiple-choice options cannot be determined accurately. The correct answer represents the duration of the longest path from the given options.
Explanation:Without the graphic showing the schedule network diagram for assembling a toy train set, providing an accurate answer would be difficult. Normally, in project management, a Critical Path represents the longest sequence of tasks (or activities) in a project schedule from start to finish. It determines the minimum total duration required to complete the project. You identify the critical path by adding the times for the activities in each sequence and determining the longest path in the project.
In this case, assuming that you have the diagram in front of you and you've calculated the total duration for all paths, one of the multiple choice options (A) 38 minutes, (B) 41 minutes, (C) 49 minutes, or (D) 51 minutes would represent the duration of the critical path in the network diagram.

Find the value of X in the diagram. HELP ASAP!!
Answer:
10 =x
Step-by-step explanation:
The figure in the diagram is an equilateral triangle, which means all sides are equal and all angles are equal. If all angles are equal, each angle is equal to 60 degrees (180/3=60). Therefore <B =60.
60 = 5x+10
Subtract 10 from each side
60-10 = 5x+10 -10
50 = 5x
Divide each side by 5
50/5 = 5x/x

There are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year. Write a function that gives the deer population P(t) on the reservation t years from now.
Answer:
[tex]P(t)=170\cdot (1.30)^t[/tex]
Step-by-step explanation:
We have been given that there are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year.
We can see that deer population is increasing exponentially as each next year the population will be 30% more than last year.
Since we know that an exponential growth function is in form: [tex]f(x)=a*(1+r)^x[/tex], where a= initial value, r=growth rate in decimal form.
It is given that a=170 and r=30%.
Let us convert our given growth rate in decimal form.
[tex]30\text{ percent}=\frac{30}{100}=0.30[/tex]
Upon substituting our given values in exponential function form we will get,
[tex]P(t)=170\cdot (1+0.30)^t[/tex]
[tex]P(t)=170\cdot (1.30)^t[/tex]
Therefore, the function [tex]P(t)=170\cdot (1.30)^t[/tex] will give the deer population P(t) on the reservation t years from now.

When navigating the maze, the robot will only need to go north, south, east, and west. It can be useful to use the complex plane to represent these directions. When using the complex plane this way, we use numbers such that their magnitude is equal to 1. If we let the value i represent the robot facing due north, what values represent the robot facing east, south, and west?
Answer:
N=i
S = -i
E =1
W = -1
Step-by-step explanation:
If facing north is represented by i, then facing south would be the opposite or -i.
We can let facing east be 1 because the magnitude has to be 1, so facing west would be the opposite or -1

What is the sum of the first 75 even numbers starting with 2? Enter your answer in the box.
Answer:
5700
Step-by-step explanation:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 2, 4, 6, 8, 10, 12, . . . . , 150.
The first term a = 2
The common difference d = 2
Total number of terms n = 75
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 75/2 x (2 + 150)
= (75 x 152)/ 2
= 11400/2
2 + 4 + 6 + 8 + 10 + 12 + . . . . + 150 = 5700
Therefore, 5700 is the sum of first 75 even numbers.
Final answer:
To find the sum of the first 75 even numbers starting with 2, use the sum of arithmetic sequence formula: (75/2) * (2 + 150) = 5,700.
Explanation:
The sum of the first 75 even numbers starting with 2 can be calculated using the formula for the sum of an arithmetic sequence. An arithmetic sequence is a sequence of numbers with a constant difference between consecutive terms. In this case, the common difference is 2, since we are dealing with even numbers.
To find the sum of the first 75 even numbers, we use the formula: Sum = (n/2) * (first term + last term), where 'n' is the number of terms. The first term is 2 and the 75th even number can be found by the formula: last term = first term + (n-1)*difference. Thus, the last term = 2 + (75-1)*2 = 2 + 148 = 150.
Using the sum formula: Sum = (75/2) * (2 + 150) = 37.5 * 152 = 5,700. Therefore, the sum of the first 75 even numbers starting with 2 is 5,700.

One side of a kite is 5 cm less than 2 times the length of another. If the perimeter is 14 cm, find the length of each side of the kite.
A) 5 cm, 5 cm
B) 4.2 cm, 3.4 cm
C) 6.3 cm, 7.7 cm
D) 4 cm, 3 cm
D) 4 cm, 3 cm
Step-by-step explanation:Let x represent the length of "another" side. Then "one side" can be represented by (2x -5 cm).
The perimeter of the kite is the sum of two sides of each length:
... P = 14 cm = 2(x) + 2(2x -5 cm)
Dividing by 2 and collecting terms, we have ...
... 7 cm = 3x -5 cm
... 12 cm = 3x
... 4 cm = x . . . . the length of "another" side
... 2(4 cm) -5 cm = 3 cm . . . . the length of "one side"
The two different side lengths are 4 cm and 3 cm.
A store has a sale on paper cups, 2 packs for $15.00. There are 100 cups in each pack. During the sale, what is the unit price per cup?
15/2=7.5
7.5/100=0.075
0.075$ per cup.
-TheOneandOnly003
The unit price per cup during the sale is calculated by dividing the total cost of $15.00 by the total number of cups (200). The result is $0.075 per cup.
Explanation:To find the unit price per cup during the sale, we must first determine the total amount of cups you are getting for the price. Given that you purchase 2 packs for $15.00, and each pack contains 100 cups, you're buying a total of 200 cups for $15.00. To get the price per cup, you then divide the total price by the total number of cups.
Step 1: Calculate the total number of cups: 2 packs * 100 cups/pack = 200 cups
Step 2: Calculate the price per cup: $15.00 / 200 cups = $0.075 per cup
So, the unit price per cup during the sale is $0.075.

A)14,76 B)16,74 C)15,78. D)13,77
Answer:
A
Step-by-step explanation:
let one acute angle be x then the other is 2x + 48
Their sum is 90 , hence
x + 2x + 48 = 90
3x + 48 = 90 ( subtract 48 from both sides )
3x = 42 ( divide both sides by 3 )
x = 14
the 2 acute angles are x = 14° and (2 × 14 ) + 48 = 28 + 48 = 76°

Daniel is 25% older than Patricia. Ten years ago, Daniel was 50% older than Patricia.
That gives us the equations 1.25d=p and 1.5(d−10)=(p−10). Solving gives us 25 for Daniel and 20 for Patricia.
Paul is two years younger than Patricia.
20−2=18
To solve the problem, we set up an equation based on the given relationships and information. After solving it, we find that Patricia is 40 years old and Paul (who is 2 years younger) is 38 years old.
Explanation:Let's denote Patricia's current age as 'P', Paul's age as 'P-2' (since Paul is 2 years younger than Patricia), and Daniel's age as 'P+0.25P' (since Daniel is 25% older than Patricia).
According to the problem, ten years ago, Daniel was 50% older than Patricia. So, we create the equation '0.5(P-10) = P+0.25P-10' to represent this situation.
Solving the equation, we find P (Patricia's current age) equals 40 years. Hence, Paul's current age would be 'P-2', which is 38 years.

How much does Robbie pay in twelve months?
$
How much more does Robbie pay?
$
What percentage does Robbie pay (to the nearest percent)?
%
Answer:
Robbie pay in twelve months $1080 .
$92.47 more Robbie pay and 9.36 %(Approx) Robbie pay.
Step-by-step explanation:
As given
Robbie Morse has a $47,500 insurance policy.
The annual premium is $987.53.
Robbie pays $90.00 monthly.
First find out the Robbie pay in twelve months .
Robbie pay in twelve months = 12 × 90
= $ 1080
Second find out how much more does Robbie pay .
Robbie pay extra = Robbie pay in twelve months - annual premium
= $ 1080 - $987.53
= $92.47
Therefore the $92.47 more Robbie pay .
Third find out the what percentage does Robbie pay .
Formula
[tex]Percentage = \frac{Robbies\ pay\ more\times 100}{annual\ premium}[/tex]
Robbies pay more = $92.47
Annual premium = $987.53
Put in the above
[tex]Percentage = \frac{92.47\times 100}{987.53}[/tex]
[tex]Percentage = \frac{9247}{987.53}[/tex]
Percentage = 9.36 % (Approx)
9.36 %(Approx) Robbie pay.
Robbie pays a total of $1,080.00 over twelve months, which is $92.47 more than the annual premium. This amount is approximately 9% more than the original annual premium.
To determine how much Robbie pays for his monthly premium over twelve months, we need to perform the following calculations:
First, calculate the total amount Robbie pays monthly. He pays $90.00 monthly, so over twelve months:
$90.00 times 12 = $1,080.00
Next, we need to find out how much more Robbie pays compared to the annual premium of $987.53:
$1,080.00 - $987.53 = $92.47
Percentage Calculation:
To find the percentage Robbie pays compared to the original annual premium, use the formula:
(difference / original amount) times 100
($92.47 / $987.53) times 100 ≈ 9%
Thus, Robbie pays approximately 9% more than the annual premium.

[tex]\text{Let the two fractions be : }\frac{1}{x}\thinspace and\thinspace \frac{1}{y}\\\\\implies \frac{1}{x}+\frac{1}{y}=\frac{3}{5}\\\\\implies 5\cdot x +5\cdot y-3\cdot x\cdot y=0[/tex]
By hit and trial method, if we put x = 2 and y = 10 then the resulting equation (1) is satisfied and all the conditions hold.
So, the denominators are 2 and 10
Through the hit and trial method, the value of the denominator 'a' is 2 and the value of denominator 'b' is 10 and there is also the use of arithmetic operations.
Given :
Noah is thinking of two fractions that have the same sum of 3/5.Each fraction has a numerator of 1.To determine the denominator of the two fractions whose sum is 3/5, first, let that numbers be 1/a and 1/b.
[tex]\dfrac{1}{a}+\dfrac{1}{b}= \dfrac{3}{5}[/tex]
[tex]5a + 5b = 3ab[/tex]
Now, put a = 2 then b becomes:
[tex]10 + 5b = 6b[/tex]
b = 10
So, through the hit and trial method, the value of a is 2 and the value of b is 10.
