(3,4) and (18,24) are ordered pairs on a line that represents a proportional relationship. which other ordered pair could be on the line?

The probability that all four will be heads or all four will be tails is 1/8.

What is probability?

Total number of outcomes = 2⁴

Probability of all four will be tails:

P(TTTT) = 1/2⁴

Probability of all four will be heads:

P(HHHH) = 1/2⁴

P(TTTT or HHHH)

= P(TTTT) + P(HHHH)

=  1/2⁴ +  1/2⁴

= 1/16 + 1/16

= 2/16

P(TTTT or HHHH) = 1/8

Hence, the probability that all four will be heads or all four will be tails is 1/8.

The reading at finished grade would be 1.5 feet.

To determine the reading at finished grade, you need to subtract the difference in elevation between the benchmark and finished grade from the initial site reading at the benchmark. In this case, the benchmark is at an elevation of 100 feet and the finish grade is set at 97 feet, which means there is a difference of 3 feet in elevation.

Given that the site reading at the benchmark is 4.5 feet, you need to subtract the 3 feet difference in elevation.

Therefore, your reading at finished grade would be 4.5 feet - 3 feet = 1.5 feet.

In conclusion, the reading at finished grade would be 1.5 feet.

Highest Common Factor is the full name for HCF in mathematics.

According to the laws of mathematics, the highest positive integer that divides two or more positive integers without leaving a residual is known as the greatest common divisor, or gcd.

Least Common Multiple is the full name for LCM in mathematics.

LCM (a,b) in mathematics stands for the least common multiple, or LCM, of two numbers, such as a and b. The smallest or least positive integer that is divisible by both a and b is known as the LCM.

We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.

Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.

We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:

288 / x² = (16*18) / x² = 288 / x²

Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.

As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

We can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.

To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.

The total area of the cake is:

16 inches x 18 inches = 288 square inches

To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:

√(288 square inches) ≈ 16.97 inches

Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:

Each piece of cake will be approximately 16 inches by 16 inches.

To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:

288 square inches ÷ (16 inches x 16 inches) = 18

Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

Solution :

From the output of regression equation given by

Number of death of children in 1991 = \($-5.21226+1.003538 \times \text{ No. of child death in 1985}$\)

Now, number of death of children in the year 1991 = \($-5.21226+1.003538 \times \text{ No. of child death in 1985}$\)

For x = no. of deaths of children in the year 1985 = 65

So substituting in the regression equation,

No. of deaths of children in year 1991 =  \($-5.21226+1.003538 \times 65$\)

                                                              = \($60.01771$\)

                                                              ≈ 60

Now residual = \($\text{observed y - predicted y}$\)

                      = \($42-60$\)

                      \($-18$\)

Part(a): Number of child deaths is,

\(1991=-5.21226+1.003538\times\)  number of child deaths in 1985

Part(b):

The number of child deaths in 1991 is 60.

Part(c): The observed is -18.

Part(a):

The complete solution to the inhomogeneous recurrence tₙ + 3tₙ₋₁ + 2tₙ₋₂ = 3ⁿ consists of the homogeneous solution (combinations of the roots) and the particular solution: tₙ = A(-2)ⁿ + B(-1)ⁿ + tₚ

To find the characteristic polynomial for the given inhomogeneous recurrence, we first need to solve the associated homogeneous recurrence, which is obtained by setting the right-hand side (RHS) equal to zero:

tₙ + 3tₙ₋₁ + 2tₙ₋₂ = 0

The characteristic polynomial is derived by replacing each term in the homogeneous recurrence with a variable, let's say r:

r² + 3r + 2 = 0

Now we can solve this quadratic equation to find the roots:

(r + 2)(r + 1) = 0

This equation has two roots:

r₁ = -2

r₂ = -1

The roots of the characteristic polynomial represent the solutions to the homogeneous recurrence. Since the equation is second-order, there are two distinct roots.

Next, we need to consider the inhomogeneous part of the recurrence, which is 3ⁿ. The inhomogeneous part does not affect the roots of the characteristic polynomial but instead contributes to the particular solution.

Since the inhomogeneous part can be parsed as 1 * 3ⁿ, we have p(n) = 1 and b = 3.

The characteristic polynomial remains unchanged:

(r + 2)(r + 1) = 0

The roots of the characteristic polynomial are:

r₁ = -2 (with multiplicity 1)

r₂ = -1 (with multiplicity 1)

These roots represent the solutions to the homogeneous recurrence.

To find the particular solution, we use the fact that b/p(n) = 3/1 = 3. Since p(n) = 1, the particular solution is a constant, which we can denote as tₚ.

Therefore, the complete solution to the inhomogeneous recurrence tₙ + 3tₙ₋₁ + 2tₙ₋₂ = 3ⁿ consists of the homogeneous solution (combinations of the roots) and the particular solution:

tₙ = A(-2)ⁿ + B(-1)ⁿ + tₚ

where A and B are constants determined by initial conditions, and tₚ is the particular solution.

Answer:

It looks like you are trying to find the retail price for a given quantity of pairs. To write an equation that could be used to find the retail price for each range of quantities, you will need to know the following information:

The retail price for the first range (0-20 pairs)

The retail price for the second range (21-40 pairs)

The retail price for the third range (41-60 pairs)

The retail price for the fourth range (61-80 pairs)

The retail price for the fifth range (81 or more pairs)

Once you have this information, you can use an if-then statement to create an equation that will work consistently for each range. The equation might look something like this:

if (quantity >= 0 and quantity <= 20):

retail_price = price for 0-20 pairs

elif (quantity >= 21 and quantity <= 40):

retail_price = price for 21-40 pairs

elif (quantity >= 41 and quantity <= 60):

retail_price = price for 41-60 pairs

elif (quantity >= 61 and quantity <= 80):

retail_price = price for 61-80 pairs

else:

retail_price = price for 81 or more pairs

This equation will work consistently for each range because it uses a series of conditions to determine which retail price to use based on the quantity of pairs.

EDIT:

To find the retail price for a given quantity of pairs based on the wholesale prices you provided, you can use the following equation:

if (quantity >= 0 and quantity <= 20):

retail_price = 25.00

elif (quantity >= 21 and quantity <= 40):

retail_price = 23.00

elif (quantity >= 41 and quantity <= 60):

retail_price = 21.00

elif (quantity >= 61 and quantity <= 80):

retail_price = 19.00

else:

retail_price = 17.00

This equation will work consistently for each range because it uses a series of conditions to determine the retail price based on the quantity of pairs. The retail price will be 25.00 for quantities in the first range (0-20 pairs), 23.00 for quantities in the second range (21-40 pairs), 21.00 for quantities in the third range (41-60 pairs), 19.00 for quantities in the fourth range (61-80 pairs), and 17.00 for quantities in the fifth range (81 or more pairs).

The probability of winning by picking the number 30 in roulette is 1/38.

In the game of roulette, the wheel consists of 38 spaces, with numbers 0 through 36 and an additional space marked 00. When you pick a specific number, such as 30, the probability of that number coming up on the wheel can be determined by calculating the ratio of favorable outcomes to the total number of possible outcomes.

In this case, there is only one favorable outcome, which is the ball landing on the number 30. The total number of possible outcomes is 38 since there are 37 numbered spaces (0 through 36) and one additional space for 00. Therefore, the probability of winning by picking the number 30 is 1 out of 38.

To put it simply, if you were to play roulette many times, you would expect the number 30 to come up approximately once every 38 spins on average. This probability remains the same for each individual spin, as each spin of the roulette wheel is an independent event.

The function f satisfying the given conditions is

f(x) = (1/2) sin(x) cos(0) + 10 = (1/2) sin(x) + 10

How to determine the function f?

To determine the function f satisfying the given conditions f ' (x) = sin(x) cos(x), f (2p) = 10, and f (x) = A sinB(x) cosC(x) + D, where A > 0, we need to follow these steps:

1. Integrate f ' (x) to find f (x).
∫(sin(x) cos(x)) dx = (1/2) * sin^2(x) + C

2. Apply the given condition f (2p) = 10.
(1/2) * sin^2(2p) + C = 10
Since sin(2p) = 0, the equation becomes:
C = 10

3. Now, we have f(x) = (1/2) * sin^2(x) + 10. We need to express this function in the form of A sinB(x) cosC(x) + D.
We can rewrite the given function as:
f(x) = A sin(2x/2) cos(0) + D
Comparing this with f(x) = (1/2) * sin^2(x) + 10, we get:

A = 1/2
B = 2/2 = 1
C = 0
D = 10

So, the function f satisfying the given conditions is:

f(x) = (1/2) sin(x) cos(0) + 10 = (1/2) sin(x) + 10
