What is the probability that a five-card poker hand contains the two of diamonds, the three of spades, the six of hearts, the ten of clubs, and the king of hearts?
The probability of drawing the two of diamonds, the three of spades, the six of hearts, the ten of clubs, and the king of hearts in that order from a 52-card deck is approximately 1 in 380,204,032.
Explanation:The subject of the question is the probability of drawing specific cards from a 52-card deck. This problem involves choosing five specific cards: the two of diamonds, the three of spades, the six of hearts, the ten of clubs, and the king of hearts.
To find the probability, we need to consider that the deck contains 52 distinct cards. Assuming that each card is equally likely to be drawn, the probability of drawing any specific card is 1 out of 52 (or 1/52). And because we want to draw these cards one after another, we multiply these probabilities together.
Thus, the probability of drawing these five specific cards from a 52-card deck in this order is (1/52) * (1/52) * (1/52) * (1/52) * (1/52), which is approximately 1 in 380,204,032. Please note that this probability is infinitesimally small because the event is highly specific. Also, the order of the cards matters in this calculation. If the order does not matter, the probability will be higher.

Martin says the area of a tile with a length of 1 foot by a width of 1 foot has an area of 1 square foot. And, to find 1/2 of this area, he would need to find 1/2 of the width and 1/2 of the length, and then multiply those two values. Unfortunately, his method is incorrect. Show at least one equation to show why this method would not work, and briefly state a method that will find 1/2 of 1 square foot.
Answer:
His method is incorrect. By finding 1/2 the width and 1/2 the length, if we multiply them , we would get 1/4 of the original area.
Area = 0.5*l*0.5*w = 0.25*l*w = l*w/4
Let us establish
length = l
width = w
Original Area = l*w
Half the area = (a*l)*(b*w) = 0.5*(l*w)
This means that
a*b = 0.5
if b is equal to a, then
a = √0.5 = √2/2 = 0.707
Then, if a factor of a, where to be introduced in the lenght and width of the tile, we would obtain half the area.

The perimeter of a rectangle is 42 centimeters.What is the length and width if the width is 3 centimeters more than half the length? Please include work.
The rectangle's length is 12 cm, and the width is 9 cm, calculated by setting up a system of equations using the given perimeter and the relationship between length and width.
Explanation:To find the length and width of the rectangle when given its perimeter and a relationship between its length and width, we can set up a system of equations. First, let's denote the length of the rectangle as L and the width as W. According to the question, the width is 3 centimeters more than half the length, so we have W = ½L + 3.
Since the perimeter (P) of a rectangle is given by P = 2L + 2W, and we know the perimeter is 42 centimeters, we can set up an equation: 42 = 2L + 2(½L + 3). Simplifying this, we get 42 = 2L + L + 6 or 42 = 3L + 6. Subtracting 6 from both sides gives us 36 = 3L or L = 12 centimeters for the length.
Now we can find the width using the previous relationship W = ½L + 3. Substituting the value of L, we get W = ½(12) + 3 = 6 + 3 = 9 centimeters for the width.
Therefore, the length is 12 centimeters and the width is 9 centimeters.

Follow the steps above and find c, the total of the payments, and the monthly payment. Choose the right answers. Jane Smart buys a new SUV. The price, including tax, is $22,500.00. She finances the vehicle over 60 months after making a $2,000 down payment. The true annual interest rate is 12%. What are Jane's monthly payments (principal plus interest)? To the nearest penny, c = $. Total of payments = amount financed + c = $. Total of payments ÷ number of payments = monthly payment = $.
To calculate Jane's monthly car loan payments, we must determine the amount financed, total of the payments, and monthly payment. After deducting the down payment from the price of the SUV, we find the amount financed. To calculate the total of the payments, we multiply the amount financed by the monthly interest rate. Finally, we divide the total of the payments by the number of months to find the monthly payment.
Explanation:To find the monthly payments for Jane Smart's car loan, we need to calculate the amount financed, the total of the payments, and the monthly payment.
First, we calculate the amount financed by subtracting the down payment from the price of the SUV: $22,500 - $2,000 = $20,500.Next, we calculate the total of the payments, which is the amount financed plus the interest. To calculate the interest, we multiply the amount financed by the true annual interest rate and divide by 12 to get the monthly interest rate: ($20,500 * 0.12) / 12 = $205.Then, we add the amount financed to the total interest to get the total of the payments: $20,500 + $205 = $20,705.Finally, we calculate the monthly payment by dividing the total of the payments by the number of months: $20,705 / 60 = $345.08 (rounded to the nearest penny).So, Jane's monthly payment for the SUV is $345.08.

In which graph does y vary directly as x? It’s not C, I got it wrong.
Answer:
A
Step-by-step explanation:
A graph where y varies directly as x is a straight line that passes through the origin (0, 0). This is because when two variables vary directly, their ratio is constant, and in the case of y and x, this ratio is the slope of the line.
The equation for direct variation is y = kx, where k is the constant of variation. When we plot this equation on a graph with y on the vertical axis and x on the horizontal axis, we get a straight line that passes through the origin, with a slope of k.
For example, if we have a set of data points that vary directly, such as (1, 2), (2, 4), (3, 6), and so on, we can plot these points on a graph and draw a straight line that passes through the origin and all the points. This line represents the direct variation between y and x, and any other points that satisfy the equation y = kx will lie on this line.
In summary, a graph where y varies directly as x is a straight line that passes through the origin, with a constant slope representing the constant of variation.

You have $3,750 to deposit. If you deposit the money in a savings account at your local bank, you will earn 1.75% annual interest and will be able to make ATM withdrawals at your bank’s ATMs. If you deposit the money in an online savings account, you will earn 3.25% interest, but you will be charged $4 every time you make an ATM withdrawal. Assuming that your ATM withdrawals do not reduce the amount of interest you earn, roughly how often must you make an ATM withdrawal for the local savings account to be a better deal than the online savings account?
To determine how often ATM withdrawals must be made for the local savings account to be a better deal than the online savings account, we compare the interest earned and ATM fees. By solving the inequality, it is found that more than $14.06 ATM withdrawals must be made in a year.
Explanation:To determine how often you must make ATM withdrawals for the local savings account to be a better deal than the online savings account, we need to compare the interest earned from each account and the fees associated with ATM withdrawals. Let's assume the time period is one year.
For the local savings account, you earn interest of 1.75% annually. So, if you deposit $3,750, you will earn ($3,750 * 1.75%) = $65.63 in interest.
For the online savings account, you earn interest of 3.25% annually. However, each ATM withdrawal incurs a fee of $4. Let's assume you make 'x' withdrawals in a year. So, the total interest earned would be ($3,750 * 3.25%) - ($4 * x).
We need to find the point where the interest earned from the online savings account is less than the interest earned from the local savings account. This can be calculated as:
($3,750 * 3.25%) - ($4 * x) < $65.63
Simplifying this inequality, we get:
0.0325 * $3,750 - $4 * x < $65.63
Adding $4 * x to both sides, we have:
0.0325 * $3,750 < $65.63 + $4 * x
Simplifying further, we get:
$121.87 < $65.63 + $4 * x
Subtracting $65.63 from both sides, we have:
$121.87 - $65.63 < $4 * x
Simplifying again, we get:
$56.24 < $4 * x
Dividing both sides by $4, we find:
$14.06 < x
So, you must make more than $14.06 ATM withdrawals in a year for the local savings account to be a better deal than the online savings account.
