The area of the trapezoid is solved and height h = 2A / ( a₁ + b₁ )

Given some information, the formula for a trapezoid's area is:

Area = (1/2) (base₁ + base₂) height

where base₁ and base₂ are the lengths of the parallel sides of the trapezoid, and height is the perpendicular distance between the parallel sides.

So, to calculate the area of a trapezoid, you need to know the lengths of the two bases and the height.

Let's say base1 = b1, base2 = b2, and height = h.

Then, the formula for the area becomes:

Area = (1/2) x (b1 + b2) x h

b = longer base of trapezium

h = height of trapezium

Now , on solving for height of trapezium , we get

A = ( ( a₁ + b₁ ) h₁ ) / 2

Multiply by 2 on :

2A = ( a₁ + b₁ ) h

Divide by ( a + b ) :

h = 2A / ( a₁ + b₁ )

Hence , the height is h = 2A / ( a₁ + b₁ )

The amount Judi invested at each rate, using simple interest are;

The amount Jodi invested at 8% = $8,000

The amount Jodi invested at 6% = $2,000

A simple interest is the amount obtained from the product of a principal and an interest rate.

The amount Jodi invested at 8% last year = Part of $10,000

The amount she invested at 6% = The rest of the $10,000 amount

The amount she received as interest at the end of the year = $760

Let x represent the amount Jodi invested at 6%, we get;

(10000 - x) × 8% + x × 6% = 760

Therefore; 800 - 0.08·x + 0.06·x = 760

800 - 0.02·x = 760

0.02·x = 800 - 760 = 40

x = 40/0.02 = 2000

The amount Jodi invests at 6%, x = $2,000

The amount she invested at 8% = $10,000 - $2,000 = $8,000

Step-by-step explanation:

The equation of the parabola that opens up or down, with a vertex at (0, 5) and passing through (-6, 4), is y = (-1/36)x^2 + 5

To find the equation of a parabola that opens up or down given the vertex and a point, we can use the standard form of the equation:

y = a(x - h)^2 + k

where (h, k) represents the vertex of the parabola. In this case, the vertex is (0, 5), so we have h = 0 and k = 5.

Now, we can substitute the given point (-6, 4) into the equation to determine the value of a:

4 = a(-6 - 0)^2 + 5

4 = 36a + 5

36a = -1

a = -1/36

Substituting the value of a back into the equation, we have:

y = (-1/36)(x - 0)^2 + 5

y = (-1/36)x^2 + 5

Therefore, the equation of the parabola that opens up or down, with a vertex at (0, 5) and passing through (-6, 4), is y = (-1/36)x^2 + 5.

We need to look at the coefficients of the x and y terms in the equation. The lengths of the transverse and conjugate axes are 10 and 14, respectively.

The standard form of the equation for a hyperbola with a horizontal transverse axis is (x-h)^2/a^2 - (y-k)^2/b^2 = 1, where (h,k) is the center of the hyperbola. In this case, the equation given is already in standard form with (h,k) = (0,0).

Comparing the given equation to the standard form, we see that a^2 = 25 and b^2 = 49. Therefore, a = 5 and b = 7.

The transverse axis is the longer axis and is parallel to the x-axis, so its length is 2a = 10. The conjugate axis is the shorter axis and is perpendicular to the transverse axis, so its length is 2b = 14.

Therefore, the lengths of the transverse and conjugate axes are 10 and 14, respectively.

The equation of the hyperbola you provided is x^2/25 - y^2/49 = 1. In this equation, we can identify the terms a^2 and b^2:

a^2 = 25
b^2 = 49

To find the lengths of the transverse and conjugate axes, we need to first find the values of a and b:

a = √25 = 5
b = √49 = 7

The length of the transverse axis is 2a, and the length of the conjugate axis is 2b. Therefore:

Length of transverse axis = 2a = 2(5) = 10
Length of conjugate axis = 2b = 2(7) = 14

So, the lengths of the transverse and conjugate axes are 10 and 14, respectively.

The dimensions that minimize the length of fencing needed are approximately 28.28 feet by 28.28 feet, creating a square-shaped playground.

To minimize the length of fencing needed for the enclosure, we need to find the dimensions that maximize the area of the playground. Since one side of the playground is already bordered by the school building, we can focus on the remaining three sides.

Let's assume the length of the playground parallel to the school building is L, and the width perpendicular to the school building is W. The area of the playground can be expressed as A = L * W.

Given that the total area of the enclosure is 800 square feet, we have the constraint L * W = 800.

To minimize the length of fencing needed, we want to maximize the area A. This occurs when the length and width are as close as possible to each other. In other words, we want to find the dimensions that form a square shape.

In a square, the length and width are equal, so we can solve the constraint equation L * L = 800.

Taking the square root of both sides, we find L = √800 ≈ 28.28 feet.

Answer:

The mean is an average general view of the data while median is the value which divides a distribution into two equal parts showing where 50% of the data lies.

Answer:

Shown below.

Step-by-step explanation:

The mean and median are both ways to describe the center of a set of numbers.

The mean is the average of all the numbers in the set. To find the mean, you add up all the numbers and divide by how many there are.

The median is the middle number in a set of numbers when they are arranged in order from smallest to largest. If there are two numbers in the middle, then the answer is simply whatever is between them.

(Ex. if the numbers were 3 and 4, the median will be 3.5.)

The biggest difference between the mean and median is that the mean is affected by outliers, which are values that are much larger or smaller than the other values in a set of data. If there are outliers in a data set, the mean will be affected more than the median.

To solve, we'll work left to right.

First, we have division. When we are dividing terms with exponents, given that the base is the same, then we need to subtract the exponents.

10^4 / 10^3 = 10^1

Next, we have multiplication. When we are multiplying terms with exponents, given that the base is the same, then we need to add the exponents.

10^1 x 10^9 = 10^10

Juan made a 10% down payment of $198 on a $1,980 tool set, leaving a remaining balance of $1,782. He will make 16 monthly payments of $116 to cover the remaining balance.

Juan purchased a tool set for $1,980 using an installment plan.
1. Down payment: Juan made a 10% down payment on the $1,980 tool set. To calculate this, multiply the total cost by the down payment percentage:
  $1,980 * 0.10 = $198
2. Remaining balance: Subtract the down payment from the total cost to find the remaining balance:
  $1,980 - $198 = $1,782
3. Monthly payments: Juan agreed to pay $116 per month to cover the remaining balance. To determine the number of months needed to pay off the balance, divide the remaining balance by the monthly payment:
  $1,782 / $116 ≈ 15.36
Since Juan can't make partial payments, he will need to make 16 monthly payments to fully pay off the balance.
4. In conclusion, Juan made a 10% down payment of $198 on a $1,980 tool set, leaving a remaining balance of $1,782. He will make 16 monthly payments of $116 to cover the remaining balance.

Answer: 5

Step-by-step explanation:

You could multiply every number but that would take too much time

Instead you have to logic through the problem

Numbers in multiplication follow cyclical sets. i.e. the ones place in the multiples of 3 goes 3,6,9,2,5,8,1,4,7,0,3 forever. (That is why 3 is a "mod 10" number there are 10 possible 1s place values)

The helpful number here is 5

5 is mod 2 because any multiple ends in a 5 or a 0. Given that you are doing all of the odd numbers, five times any odd number will end in a 5, and any odd number ending in 5 times another odd number will also end in 5 so the ones place for all odd numbers multiplied from 1 to 2023 is 5.

When multiplying all the odd numbers from 1 to 2023, inclusive, the last digit of the product will be 5. This is based on the pattern observed in the last digits of the products of odd numbers.

In mathematics, specifically in number theory, we often make use of patterns to solve problems. When you're asked to find the last digit of the product when you multiply all the odd numbers from 1 to 2023, inclusive, it is helpful to look for a pattern in the last digits of the products of odd numbers.

Let's start small. The first five odd numbers are 1, 3, 5, 7, and 9. The product of these numbers is 945, and the last digit, or unit digit, is 5. Let's add another odd number to the product, 11. The product becomes 10395, and again, the unit's digit is 5. As you can see, the pattern is that no matter how many odd numbers you multiply together, the unit's digit (or the last digit) of the product is always 5.

Therefore, when you multiply all the odd numbers from 1 to 2023, inclusive, the last digit of the product will be 5.

Therefore, the estimated average length of the line is 3 customers.

We can approach this problem by using the M/M/1 queueing model, which assumes a Poisson arrival process, an exponential service time distribution, and a single server.

In this case, the arrival rate (lambda) is 10 customers per hour, the service rate (mu) is 5 customers per hour (since the average servicem time is 14 minutes or 0.2333 hours), and there is one server.

The utilization factor (rho) is given by rho = lambda / mu = 10 / 5 = 2, which is greater than 1. This means that the system is not stable, and the queue will grow indefinitely.

To find the average length of the line, we can use Little's Law, which states that the long-term average number of customers in a stable system is equal to the long-term average arrival rate multiplied by the long-term average time spent in the system:

L = lambda * W

where L is the average number of customers in the system, lambda is the arrival rate, and W is the average time spent in the system.

In this case, since the system is not stable, we cannot use Little's Law directly. However, we can still estimate the average length of the line as follows:

Let's assume that the queue is at its steady-state when there are N customers in the system (i.e., being served plus waiting in the line). Then, the average length of the line (Lq) is:

Lq = N - 1

since one customer is being served and the remaining N-1 customers are waiting in the line.

The steady-state condition requires that the arrival rate equals the departure rate, which is the service rate in this case. Therefore, we can use the following formula to estimate N:

N = lambda / (mu - lambda)

Plugging in the values, we get:

N = 10 / (5 - 10) = -2

This negative value indicates that the system is not stable, and there are more customers arriving than the system can handle. However, we can still estimate the average length of the line as:

Lq = |N - 1| = |-2 - 1| = 3

Answer:

the 1rst one.

Step-by-step explanation:

because the other ones represent vertical curves which is impossible.

The probability that strictly more than 5 customers arrive in a given hour is approximately 0.8335 (or 83.35%).

Let's denote the random variable representing the number of customers arriving in an hour as X, which follows a Poisson distribution with a mean of 11.

To calculate P(X > 5), we need to sum the probabilities of X being greater than 5 for all possible values of X greater than 5.

P(X > 5) = 1 - P(X ≤ 5)

Using the Poisson distribution formula, we can calculate the cumulative probability of X being less than or equal to 5:

P(X ≤ 5) = Σ [e^(-λ) * (λ^k) / k!] for k = 0 to 5

Substituting the mean λ = 11 into the formula, we get:

P(X ≤ 5) = Σ [e^(-11) * (11^k) / k!] for k = 0 to 5

P(X ≤ 5) ≈ 0.1665

Finally, calculating P(X > 5) using the complement rule:

P(X > 5) = 1 - P(X ≤ 5)

P(X > 5) ≈ 1 - 0.1665

P(X > 5) ≈ 0.8335

Next, we need to find out the minimum percent of people who like tennis that could also like baseball. To do this, we need to consider the fact that there could be some people who like tennis but not baseball, and we want to find the lowest possible percentage of people who like both sports.

Let's say that x% of people surveyed like tennis but not baseball. This means that (100-x)% of people who like tennis also like baseball. We want to find the minimum value of (100-x)% that would still satisfy the conditions given in the problem.

We know that 10% of people surveyed like both baseball and tennis. This means that (100-x)% of people who like tennis but not baseball is equal to 90%.

Using a bit of algebra, we can solve for x:

(100-x)% * 90% = 10%

Simplifying this equation, we get:

(100-x)% = 10%/90%

(100-x)% = 11.11%

Therefore, the minimum percent of surveyed people who like tennis that could also like baseball is 11.11%.

In summary, of the surveyed people that like tennis, the minimum percent that could like baseball is 11.11%. This is found by considering the fact that 50% of people who like baseball also like tennis, and finding the minimum percentage of people who like tennis but not baseball that would still allow for the 10% of people who like both sports.

For the given quadrilateral the value of p is 8, UV = 70 and VW = 34. The property of parallelogram used is the opposite sides are parallel and equal.

Step-by-step explanation:

A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides consist of equal length, and the opposing angles are of equal size. Also, the interior angles that are additional to the transversal on the same side. 360 degrees is the total of all interior angles.

The opposing sides are equal and parallel. Angles on either side are equivalent.  All of the angles will be at right angles if any one of them is a right angle.

We know that the opposite sides of a parallelogram are parallel and equal making this:

8p + 6 = 9p – 2

6 + 2 = 9p – 8p

8 = p

Now, the value of side is:

UV = 8(8) + 6 = 70

The value of side VW is:

VW = 5(8) – 6 = 34

The given quadrilateral the value of p is 8, UV = 70 and VW = 34. The property of parallelogram used is the opposite sides are parallel and equal.
