Given a standard deck of 52 playing cards, a) if you draw one card at random, what is the probability it is a two or a four? b) if you draw one card at random, what is the probability it is a spade or a King? c) if you draw two cards at random, what is the probability of drawing two hearts, with replacement? d) if you draw two cards at random, what is the probability of drawing two Aces, without replacement?
a) If you draw one card at random, the probability it is a two or a four is 4/52 or 1/13.
b) If you draw one card at random, the probability it is a spade or a King is 16/52 or 4/13.
c) If you draw two cards at random, the probability of drawing two hearts, with replacement is
(13/52) × (13/52) = 169/2704 or 1/16.
d) If you draw two cards at random, the probability of drawing two Aces, without replacement is (4/52) × (3/51) = 12/2652 or 1/221.
Solution details:
a) If you draw one card at random, the probability it is a two or a four is 4/52 or 1/13.
There are four 2s and four 4s in the deck.
Therefore, the probability of drawing one of these cards is 4/52.
Simplifying it, 1/13.
b) If you draw one card at random, the probability it is a spade or a King is 16/52 or 4/13.
There are four Kings in the deck, and there are 13 spades in the deck, including the King of spades.
There are four Kings, including the King of spades.
Four plus 13 equals 16 total cards.
The probability of drawing one of these cards is 16/52.
Simplifying it, 4/13.
c) If you draw two cards at random, the probability of drawing two hearts, with replacement is
(13/52) × (13/52) = 169/2704 or 1/16.
There are 13 hearts in the deck, and we’re assuming that you’re drawing with replacement.
As a result, the probability of drawing two hearts is (13/52) × (13/52).
Simplifying it, 169/2704.
d) If you draw two cards at random, the probability of drawing two Aces, without replacement is (4/52) × (3/51) = 12/2652 or 1/221.
Since the first ace has a probability of 4/52, or 1/13, the probability of the second ace is 3/51.
This is since one card has been removed from the deck, making it 51 instead of 52.
Multiplying the two probabilities gives us (4/52) × (3/51) or 12/2652. Simplifying it, 1/221.

Use iteration to guess an explicit formula for the following sequence - dx = 2dx-1 + 3k2 , for all integers k> 1 and do = 3 You must show your work.
By using iteration, we can guess the explicit formula for the given sequence. It is found that the sequence follows a quadratic pattern, and the explicit formula is dx = 3(\(2^{k-1}\)) + 3\(k^2\) - 6k + 3.
Let's start by analyzing the given sequence: dx = 2dx-1 + 3\(k^2\). We are given that d1 = 3. We can use this initial value to find d2, d3, and so on.
Substituting k = 2 into the given equation, we get d2 = 2d1 + 3(\(2^2\)) = 2(3) + 3(4) = 6 + 12 = 18.
Similarly, substituting k = 3, we get d3 = 2d2 + 3\((3^2)\) = 2(18) + 3(9) = 36 + 27 = 63.
Based on these calculations, we observe that each term in the sequence is related to the previous term by multiplying it by 2 and adding 3\(k^2\). Moreover, we notice a quadratic pattern in the sequence.
To find the explicit formula, we can express dx in terms of k:
dx = 2dx-1 + 3\(k^2\)
= 2(2dx-2 + 3\((k-1)^2\)) + 3\(k^2\)
= 4dx-2 + 6\((k-1)^2\)\((k-1)^2\) + 3\(k^2\).
We can continue this iteration process, expanding dx-2 in terms of dx-3, and so on. By continuing this process and simplifying the equation, we find that the explicit formula for the sequence is dx = 3(\(2^{k-1}\)) + 3\(k^2\) - 6k + 3.
In conclusion, by using iteration, we have determined that the explicit formula for the given sequence dx = 2dx-1 + 3\(k^2\), with d1 = 3, is dx = 3(\(2^{k-1}\)) + 3\(k^2\) - 6k + 3.

Answer:
53/100
Step-by-step explanation:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
8 / 15 = 0.533
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 533
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:
0.53
Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:
0.53 = 0.53/1
Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:
(0.53 x 100) / (1 x 100) = 53/100
That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):

One day, you decide to buy a Mega Millions ticket, and you end up winning $20000. You invest your winnings with PNC Bank in a money market account which earns 6% interest every half-year.
How much money in interest have you earned from your Mega Millions winnings after 7 years of investing in your PNC Bank money market account? [Include a dollar sign in your answer and round to the nearest penny.]
$45218.1
.
The amount of interest earned from the Mega Millions winnings after 7 years of investing in the PNC Bank money market account at 6% interest every half-year is $25,218.08.
How the interest is computed?The interest rate is increased to 12% because 6% every half-year translates to 12% annually.
The compounding period is 14 semi-annual periods because in 7 years there are 14 compounding periods.
N (# of periods) = 14 semi-annual periods (7 years x 2)
I/Y (Interest per year) = 12% (6% x 2)
PV (Present Value) = $20,000
PMT (Periodic Payment) = $0
Results:
Future Value (FV) = $45,218.08
Total Interest = $25,218.08
Thus, from the investment of $20,000 at 6% every half- year, you earn an interest of $25,218.08.

5. It is known that 15% of the seniors in a large high school enter military
service upon graduation. If a group of 20 seniors are randomly selected,
what is the probability of observing two who will be entering military
service? *
Answer:
Hope this helps you. Do mark me as brainliest.
The probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.
What is a Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
\(P(x) = ^nC_x p^xq^{(n-x)}\)
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
As it is given that 15% of the seniors in a large high school enter military
service upon graduation. Therefore, the probability of a large high school entering the military services will be 0.15. Similarly, the probability of a senior from a large high school not joining entering the military can be written as,
\(q = (1-p)\\\\q = 1-0.15\\\\q=0.85\)
Now, the probability of 2 seniors out of 20 serving in the military will be,
\(P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(20-2)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(18)}\)
Hence, the probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.

Consider the function g(x)=−(x−1)^3−2. Which ordered pair lies on the inverse of the function?
(62,−3)
(−4, 123)
(3, 1)
(3,−6)
The ordered pair lie on the inverse of the function is (62,−3).
Option A is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = -(x - 1)³ - 2
The inverse of f(x).
y = -(x - 1)³ - 2
interchange x and y and solve for y.
x = -(y - 1)3 - 2
(y - 1)³ = -2 - x
(y - 1)³ = -(2 + x)
Cuberoot on both sides.
y - 1 = ∛-(2 + x)
y = ∛-(2 + x) + 1
Now,
Substitute in the inverse of g(x).
(62, -3) = (x, y)
(−4, 123) = (x, y)
(3, 1) = (x, y)
(3,−6) = (x, y)
So,
y = ∛-(2 + x) + 1
y = ∛-(2 + 62) + 1
∛-1 = -1
y = -1∛64 + 1
y = -1 x 4 + 1
y = -4 + 1
y = -3
So,
(62, -3) ______(1)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 - 4) + 1
∛-1 = -1
y = ∛(-2 + 4) + 1
y = ∛2 + 1
y = 1.26 + 1
y = 2.26
So,
(-4, 2.26) _______(2)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 + 3) + 1
∛-1 = -1
y = -1∛5 + 1
y = -1 x 1.71 + 1
y = -1.71 + 1
y = -0.71
So,
(3, -0.71) _______(3)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 + 3) + 1
∛-1 = -1
y = -1∛5 + 1
y = -1 x 1.71 + 1
y = -1.71 + 1
y = -0.71
So,
(3, -0.71) ______(4)
Thus,
From (1), (2), (3), (4) we see that,
(62, -3) is the solution to the inverse of g(x).

let ~u and ~v be vectors in three dimensional space. if ~u ×~v = ~0, then ~u = ~0 or ~v = ~0. state if this is true or false. explain why.
The statement is true because if the cross product of two vectors ~u and ~v in three-dimensional space is equal to the zero vector ~0, then it implies that either ~u or ~v is equal to the zero vector ~0.
The cross product ~u × ~v produces a vector that is perpendicular (orthogonal) to both ~u and ~v. If the resulting cross product is the zero vector ~0, it means that ~u and ~v are either parallel or collinear.
If ~u and ~v are parallel or collinear, it implies that they are scalar multiples of each other. In this case, one of the vectors can be expressed as a scaled version of the other. Consequently, either ~u or ~v can be the zero vector ~0.

1. Determine the lateral and total surface
area of the pyramid.
(I need full explanation on how to solve
Answer:
Laterial surface area: 73 cm²Total surface area: 93 cm²Step-by-step explanation:
The laterial surface area is the sum of the areas of the triangles. There are two triangles with dimensions: base = 4 cm, height = 8cm and two triangles with dimensions: base = 5cm, height = 8.2cm.
The laterial surface area LSA is:
LSA = 2 • ( 4.8/2) + 2 • ( 5 • 8.2/2)
LSA = 4 • 8 + 5 • 8.2
LSA = 73 cm²
The total surface area SA is the LSA plus the area of the base of the pyramid, which is a rectangle with dimensions: 4cm x 5cm:
SA = LSA + 4 • 5
SA = 73 cm + 20 cm²
SA = 93 cm²

production possibilities frontier for a country is typically
concave to the origin (le,, bowed out) because productive resources
(land, labour and physical capital)
Answers A - D
A.are used in equal p
The production possibilities frontier (PPF) for a country is typically concave to the origin, meaning it is bowed outwards. This occurs because productive resources, such as land, labor, and physical capital, are not equally efficient in producing different goods or services.
The concave shape of the production possibilities frontier (PPF) reflects the concept of diminishing returns or increasing opportunity costs. As a country allocates more resources to the production of one good, it must sacrifice the production of other goods. However, as more resources are diverted towards a specific good, the additional output gained becomes smaller and smaller.
This occurs because not all productive resources are equally efficient in producing all goods or services. Some resources may be better suited for specific industries or have specialized skills. As a result, the PPF is bowed outwards, indicating that the opportunity cost of producing more of one good increases as the production of the other good is reduced.
In summary, the concave shape of the production possibilities frontier is a result of the varying efficiency and specialization of productive resources in different industries. This leads to increasing opportunity costs and the bowed-out nature of the PPF.

The number of children admitted is 164 and the number of adults admitted is 195
Finding Unkown numbers using Linear EquationA linear Equation is a mathematical expression that is used to find unknown numbers. In this, we use different variables to represent the unknown number.
To find the unknown number obtain a linear equation according to the given condition and solve the equations.
Here we have,
The admission fee for children is 1.5 dollars
The admission fee for adults is 4 dollars
On a certain day, 359 entered the park
Since we don't know the number of children and adults we will use different variables to represent them as shown below
Let x be the number of children
Let y be the number of adults
From the given data
=> x + y = 359 -----(1)
Admission fee collected for x children = 1.5 × x = 1.5x
Admission fee collected for y adults = 4 × y = 4y
And total fee collected = 1.5x + 4y = 1026 ----(2)
To find the number of children and adults solve (1) and (2)
(1) × 1.5 => 1.5x + 1.5y = 538.5 ---- (3)
Now do (2) - (3)
=> 1.5x + 4y - (1.5x + 1.5y) = 1026 - 538.5
=> 1.5x + 4y - 1.5x - 1.5y = 487. 5
=> 2.5y = 487. 5
=> y = 487. 5 /2 = 195
Now substitute y = 195 in (1)
=> x + 195 = 359
=> x = 164
Therefore,
The number of children admitted is 164 and the number of adults admitted is 195
