The table below shows the linear relationship between the number of people at a picnic and the total cost of the picnic.
The line represented by the table is:
y = 2x + 40
How to find the linear relationship?A general linear relationship is written as:
y = ax + b
Where a is the slope and b is the y-intercept.
If the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
We can use the first two pairs:
(6, 52) and (9, 58)
Then we will get:
a = (58 - 52)/(9 - 6)
a = 6/3 = 2
y = 2x + b
To find the value of b, we replace the values of one of the points, if we use the first one (6, 52), then we will get:
52 = 2*6 + b
52 = 12 + b
52 - 12 = b
40 = b
The line is:
y = 2x + 40

what is the probability of correctly choosing (in any order) 4 numbers that match 4 randomly selected balls from a bucket of 35 balls with the different numbers 1 to 35 on them? please enter your answer as a fraction.
The probability of correctly choosing 4 numbers that match 4 randomly selected balls from a bucket of 35 balls is 1/52360.
To calculate the probability of correctly choosing 4 numbers that match 4 randomly selected balls from a bucket of 35 balls with different numbers from 1 to 35, we need to consider the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes:
Since there are 35 balls in the bucket, the total number of possible outcomes is given by the combination formula:
nCr = n! / [(n-r)! * r!]
In this case, we need to choose 4 balls out of 35, so the total number of possible outcomes is:
35C4 = 35! / [(35-4)! * 4!]
Number of favorable outcomes:
We want to choose 4 numbers that match the 4 randomly selected balls. Since there are 4 balls that need to match, we can consider this as choosing all 4 numbers correctly.
There is only 1 way to choose all 4 numbers correctly.
Therefore, the number of favorable outcomes is 1.
Probability:
The probability of an event is given by the formula:
Probability = Number of favorable outcomes / Total number of possible outcomes
In this case, the probability is:
Probability = 1 / 35C4
Now, let's calculate the probability:
35C4 = 35! / [(35-4)! * 4!]
= (35 * 34 * 33 * 32) / (4 * 3 * 2 * 1)
= 52360
Probability = 1 / 52360

show that the share of income spent on good xi can always be measured by ∂ ln[e(p, u∗ )]/∂ ln(pi ), where u∗ ≡ v(p, y)
The share of income spent on good xi can always be measured by ∂ ln[e(p, u*)]/∂ ln(p_i). This expression is often called the Hicksian demand function for good xi, which gives the optimal quantity of xi demanded as a function of prices and utility, holding income constant at its utility-maximizing level.
Let xi be a good and let p be a vector of prices for all goods, and let u∗ ≡ v(p, y) be the indirect utility function, where y is the consumer's income. We want to show that the share of income spent on good xi can be measured by the partial derivative of the logarithm of the expenditure function with respect to the logarithm of the price of good xi.
The expenditure function e(p, u) gives the minimum expenditure needed to achieve a given level of utility u, given prices p. It can be written as:
e(p, u) = min {px | v(p, x) = u}
where x is a bundle of goods that achieves the utility level u, and px is the expenditure on that bundle.
Now, consider the expenditure function at the utility level u*, which is e(p, u*) = min {px | v(p, x) = u*}. Taking the logarithm of both sides, we get:
ln(e(p, u*)) = ln(min {px | v(p, x) = u*})
Using the fact that the logarithm is a monotonic function, we can write:
ln(e(p, u*)) = ln(px*)
where x* is the bundle that minimizes expenditure at the utility level u*.
Taking the total differential of ln(e(p, u*)) with respect to p_i, we get:
d ln(e(p, u*))/d ln(p_i) = d ln(px*)/d ln(p_i)
By the chain rule of differentiation, we have:
d ln(px*)/d ln(p_i) = d ln(px*)/d p_i * p_i / px*
The first term on the right-hand side is the elasticity of expenditure on good i with respect to its own price, and the second term is the share of income spent on good i. Hence, we have:
d ln(e(p, u*))/d ln(p_i) = η_i * s_i
where η_i is the elasticity of expenditure on good i with respect to its own price, and s_i is the share of income spent on good i.

With similar triangles the corresponding angles are equal.
In similar triangles, corresponding angles are equal.
Similar triangles are triangles that have the same shape but may have different sizes. When two triangles are similar, their corresponding angles are equal. This means that if you have two triangles with the same angles, their corresponding sides will be proportional. Corresponding angles are the angles that occupy the same position in each triangle. For example, if two triangles have corresponding angles of 30° and 50°, then the corresponding angles in any other pair of similar triangles with the same shape will also be 30° and 50°. This property is useful in solving problems involving similar triangles, such as finding missing side lengths or angles.

Answer:
1256 meters
Step-by-step explanation:
The distance around the circle (circumference) can be found using the formula \(2\pi r\). r is the radius, which you're given. So 2 * pi * 10 is 62.8 if you use 3.14 as pi. Since the horse went around 20 times, we multiply the circumference by 20. 62.83 * 20 = 1256

Answer: v(t)=
The velocity v as a function of t is 4t³ - 4
Now, we are asked to find the velocity v as a function of t. Velocity is the rate of change of position with respect to time. Mathematically, we can express velocity as the derivative of position with respect to time, or v = ds/dt, where s is the position function and t is the time variable.
To find the velocity v as a function of t, we need to take the derivative of the position function s with respect to time. In this case, s = t⁴ - 4t, so we can use the power rule of differentiation to find ds/dt:
ds/dt = 4t³ - 4
Therefore, the velocity v as a function of time t is:

At age 45 when the deferred payments from his current contract ends, all-star shortstop Alex Rodriguez plans to have $230 million in savings from his baseball playing days. He wants two things from his savings: a 40-year ordinary annuity and $500 million at age 60 in order to purchase majority ownership in his native Miami's Florida Marlins. How large can his annual annuity payment be based on this information and assuming his savings can earn 8% annually after age 45 ? $6,069,727 $5,620,118 $6,906,832 $6,395,215
Therefore, the annual annuity payment can be approximately $6,069,727.
To calculate the size of the annual annuity payment, we can use the present value formula for an ordinary annuity. The formula is given by:
PMT = PV / [(1 - (1 + r)⁻ⁿ) / r]
Where:
PMT = Annual annuity payment
PV = Present value of the annuity
r = Annual interest rate
n = Number of periods
Given:
PV = $230 million
r = 8% = 0.08
n = 40 years
Using the formula, we can calculate the annual annuity payment:
PMT = 230,000,000 / [(1 - (1 + 0.08)⁻⁴⁰) / 0.08]
PMT ≈ $6,069,727

Use generating functions to select the correct number of different ways 10 identical balloons can be given to four children if each child receives at least two balloons. a. 8
b. 9
c. 10 d. 11
The correct number of different ways 10 identical balloons can be given to four children if each child receives at least two balloons is 11. This can be answered by the concept of Combination.
To solve this problem, we can use generating functions, which are a powerful tool in combinatorics for counting the number of ways to distribute objects. Let's define a generating function for each child, representing the number of balloons they receive.
Let the generating function for the first child be represented as x², as each child must receive at least two balloons. Similarly, the generating functions for the other three children would also be x² each.
Now, we can multiply these generating functions together to represent the combined number of balloons given to all four children. Multiplying x² four times gives us (x²)⁴, which simplifies to x⁸.
Finally, we need to find the coefficient of x¹⁰ in the expansion of x⁸. This represents the number of ways to distribute 10 identical balloons among the four children, with each child receiving at least two balloons.
Using the binomial theorem or simply by expanding (x²)⁴, we get the coefficient of x¹⁰ to be 11.
Therefore, The correct number of different ways 10 identical balloons can be given to four children if each child receives at least two balloons is 11
