The value of angle x is determined as 107⁰.

What is the x?

The value of angle x is calculated by applying principle of intersecting chord theorem.

The intersecting chord theorem states that half of the difference between the arc of two intersecting chords is equal to the tangent angle.

Based on the angle of intersecting chord theorem, we will have the following equation.

m∠MNP = ¹/₂( arc MLP - arc MP )

x = ¹/₂ [(360 -73) - (73)]

x = ¹/₂ (287 - 73 )

x = ¹/₂ (214)

x = 107⁰

Qd=50-4Px+0.5I+10Py-2Pz

Answers

Answer:

The equation Qd = 50 - 4Px + 0.5I + 10Py - 2Pz represents the demand function for a certain good X, where Qd is the quantity demanded, Px is the price of X, I is the consumer's income, Py is the price of another good Y, and Pz is the price of another good Z.

To solve for the equilibrium price and quantity, we need to find the point where the quantity demanded equals the quantity supplied. However, without information on the supply function or market conditions, we cannot find the equilibrium price and quantity.

We can use the demand equation to determine the effect of changes in the independent variables on the quantity demanded for the good. For example, an increase in the price of X (Px) would lead to a decrease in the quantity demanded (Qd), while an increase in the price of Y (Py) or a decrease in the price of Z (Pz) would lead to an increase in the quantity demanded (Qd). An increase in income (I) would also lead to an increase in the quantity demanded (Qd).

Note that it is important to understand the context and assumptions underlying the demand function in order to make accurate economic predictions or decisions based on it.

1. What would you get in your numerator when you multiply your terms together in the first step in simplifying?

2. What two terms would you combine in the numerator to simplify?

Answers

The step in simplifying the expression 3x/(x+5) - 3/(x+6) would result in 3x² + 18x - 3x - 15. The two terms that can be combined in the numerator to simplify are -3x and 18x. So, the correct answer is A), B) and D).

When multiplying the terms together in the first step of simplifying, we would get

3x - 3(x + 5)/(x + 6)

Simplifying this expression would lead to

3x² + 15x - 3x - 15/(x + 6)

Therefore, the answer is option (b): 3x² + 18x - 3x - 15

To simplify the numerator, we need to combine like terms.

To simplify the numerator, we need to combine like terms. The given expression is

3x² + 18x - 3x - 15

Here, the terms 18x and -3x have the same variable (x) and the same power (first power), but they have opposite signs. Therefore, we can combine them by subtracting the smaller value from the larger value. In this case, we have

18x - 3x = 15x

So, the expression simplifies to

3x² + 15x - 15

Therefore, the two terms that we would combine in the numerator to simplify are -3x and 18x, which give us 15x. So, the correct option is B) and D).

Bacteria was put in a petri dish with antibacterial soap. Determine the logarithmic regression of the bacteria. Use either a
calculator or spreadsheet program.

Answers

Using the given data, a logarithmic regression equation of the form Bacteria = 447.91 * ln(12) - 1733.1 was found to model the relationship between time and bacteria population. So, the population of bacteria is about 44.1 at 12 hours.

Based on the provided data, we can use a logarithmic regression to model the relationship between time and bacteria population. Here's how to do it using Microsoft Excel

Enter the data into two columns one for time and one for bacteria population. Create a scatter plot of the data. Right-click on one of the data points in the plot and select "Add Trendline."

In the Trendline options, choose "Logarithmic" as the type of trendline. Check the box for "Display Equation on Chart" to show the equation for the trendline.

The resulting equation is

Bacteria = 447.91 * ln(Time) - 1733.1

This equation represents a logarithmic regression of the bacteria population over time.

To use this equation to predict the bacteria population at a specific time, substitute the time value into the equation and solve for the bacteria population. For example, if we want to predict the bacteria population at 12 hours, we can substitute 12 into the equation

Bacteria = 447.91 * ln(12) - 1733.1

Bacteria ≈ 44.1

So we would predict a bacteria population of about 44.1 at 12 hours.

What is a z-distribution confidence interval?

The bounds of the confidence interval are given by the rule presented as follows:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.

The margin of error is defined as follows:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

Use

S as the number of short sleeve shirts and

L as the number of long sleeve shirts.


PLS HELP

Answers

Answer:

Let's set up a system of equations to solve for S and L:

S + L = 24 (they sold a total of 24 shirts)

14S + 17L = 378 (the total amount made from selling the shirts was $378)

We can solve for one variable in the first equation and substitute it into the second equation:

S = 24 - L

14(24 - L) + 17L = 378

336 - 14L + 17L = 378

3L = 42

L = 14

So they sold 14 long sleeve shirts. We can substitute this value back into the first equation to solve for S:

S + 14 = 24

S = 10

Therefore, they sold 10 short sleeve shirts and 14 long sleeve shirts.

What are the inventory cost valuation methods?

The inventory cost valuation methods include FIFO (First In, First Out), LIFO (Last In, First Out), WAC (Weighted Average Cost), and Specific Identification.

Under the FIFO basis, the cost of inventory is evaluated based on the assumption that inventory that are first brought in are the first to be sold.

Under the Weighted Average Cost method, the average cost is computed by dividing the total cost of goods available for sale by the number of units.

Other inventory cost valuation methods include LIFO and Specific Identification.

FIFO Basis:

Cost of Goods Sold = $80,000 ($10,000 x 3 + $12,000 x 2 + $13,000 x 2)

Sales Revenue = $106,000 ($15,000 x 7)

Total                          30                     90                           120

In this situation there were total 120 seventh and eighth grade CAVA students. And there were a total of 60 eighth grade students.

Total number of students = 120

This means that the number of students in 7th grade : 120- 60 = 60

Out of 120 seventh and eighth grade students, 30 students chose Music as their elechive course.

This means that remaining 120 - 30 = 90 students chose World Language as their elechive course.

Here, 40 eighth grade students chose World Language as their elective.

This means that out of total 90 students 90 - 40 = 50 students of 7th Grade  chose World Language as their elective.

Now consider the 8th grade students,

Out of 60 students 40 chose World Language.

So, 60 - 40 = 20 must chose Music as their elective.

Now consider the 7th grade students,

Out of 60 students 50 chose World Language.

So, 60 - 50 = 10 students must chose Music as their elective.

How to describe the distribution ?

One can utilize the Central Limit Theorem (CLT) for proportions to detail the dispersion of the sample proportion. Explained by the CLT, if the size of the sample is sufficiently significant enough, then the distribution with respect to the sample proportion will be mostly indistinguishable from a typical distribution.

np ≥ 10

Step-by-step explanation:

First, we need to find the values of A-C and B-D:

A-C = < 3, 6 > - < 7, -3 > = < -4, 9 >

B-D = < 4, -7 > - < 0, 2 > = < 4, -9 >

Next, we need to find the magnitude of A-C, which is denoted by |A-C| and is equal to the square root of the sum of the squares of its components:

|A-C| = √((-4)^2 + 9^2) =√(97)

Now we can substitute all the values into the expression |A-C|(B-D) and evaluate:

|A-C|(B-D) = √(97) * < 4, -9 >

= < 4√(97), -9√(97) >

So the final answer is < 4√(97), -9√(97) >.

cost minimal of logistic form factory to
warehouse mathematical problem

Answers

Answer:

To calculate the minimal cost of logistics from a factory to a warehouse, you would need to consider various factors such as the distance between the factory and the warehouse, the mode of transportation, the weight and volume of the goods being transported, the number of trips required, and any applicable taxes or fees.

To formulate this as a mathematical problem, you could use linear programming, which is a method for optimizing a linear objective function subject to linear equality and inequality constraints.

Let's say we have a factory that produces goods and a warehouse that stores those goods. We want to transport the goods from the factory to the warehouse in a cost-effective way. Let's assume that there are three transportation options available: truck, train, and ship. Each option has a different cost per unit of distance traveled, and a different maximum weight and volume capacity.

Let x1, x2, and x3 be the number of units transported by truck, train, and ship, respectively. Then, the objective function we want to minimize would be:

C = 10x1 + 8x2 + 6x3

where C is the total cost of transportation.

Next, we would need to set up constraints based on the transportation options and the available resources. For example:

Truck capacity: 3x1 <= 15000 (maximum weight capacity of 15000 units for the truck)

Train capacity: 5x2 + 2x1 <= 40000 (maximum weight capacity of 40000 units for the train)

Ship capacity: 2x3 + 3x1 <= 30000 (maximum weight capacity of 30000 units for the ship)

Distance constraint: 2x1 + 3x2 + 5x3 <= 10000 (maximum distance of 10000 units for all transportation modes combined)

The above constraints limit the total weight transported, the capacity of each mode of transport, and the total distance that the goods are transported.

Finally, we would need to add non-negative constraints to ensure that all variables are greater than or equal to zero:

x1 >= 0, x2 >= 0, x3 >= 0

Once we have set up this linear programming problem, we can use optimization techniques to solve for the values of x1, x2, and x3 that minimize the cost of transportation while satisfying all of the constraints.

Answers

We would expect 138 groups in the larger zoo to have 5 or more people based on the relative frequency of group sizes in Julia's data.

To determine how many groups of 5 or more people we would expect to see in a larger zoo with 600 groups of visitors in a day, we need to use the relative frequency of each group size in Julia's data.

To calculate the relative frequency of each group size, we need to divide the frequency of each group size by the total number of groups:

Group Size   Frequency   Relative Frequency

1                          9             9/150 = 0.06

2                         52           52/150 = 0.35

3                         27            27/150 = 0.18

4                         38            38/150 = 0.25

5                         16             16/150 = 0.11

6                          6              6/150 = 0.04

7                          5              5/150 = 0.03

8                          7              7/150 = 0.05

We can see that the relative frequency of groups with 5 or more people is 0.11 + 0.04 + 0.03 + 0.05 = 0.23. This means that we would expect 23% of the 600 groups in the larger zoo to have 5 or more people.

To calculate the actual number of groups with 5 or more people, we multiply the total number of groups by the relative frequency:

Number of groups with 5 or more people = 600 x 0.23 = 138
