Answer:

m∠1 = 130°

m∠2 = 158°

Step-by-step explanation:

For the given figure, we have;

The measure of angle m∠1 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;

m∠1 = 99° + 31° = 130°

m∠1 = 130°

Similarly, the measure of angle m∠2 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;

m∠2 = 28° + m∠1 = 28° + 130° = 158°

m∠2 = 158°.

The change in the price of the company's stock from the beginning of the 6-week period to the end of it is a decrease of $7.50.

The change in the price of the company's stock from the beginning of the 6-week period to the end of it is calculated by multiplying the number of weekdays in 6 weeks by the daily decrease in stock price.

First, we need to determine the number of weekdays in 6 weeks. There are 5 weekdays in a week, so we multiply 5 by 6 to get 30 weekdays.

Next, we multiply the number of weekdays (30) by the daily decrease in stock price ($0.25) to find the total decrease in stock price over the 6-week period.

30 weekdays * $0.25 decrease per day = $7.50

Therefore, the change in the price of the company's stock from the beginning of the 6-week period to the end of it is a decrease of $7.50.

He continues to double the FULL amount so he doubles 20 for March which gets us 40, then we again take 6 away leaving us with 34. We do the same thing for April. Double 40 getting 80, take away 6 you get 74. Done.

Answer b. The probability that at least 41 of them like to swim is 33%.

Solution:

The probability of an event is always 1 or 100%

The probability of at most 40 of them like to swim is 67% = 0.67

The probability of at most 40 not swimming = 1 - 0.67 = 0.33

Hence the probability of at least 41 people swimming is 33%.

A solution that does not simultaneously satisfy all constraints is called an infeasible solution.

Option (C) is correct.

What is linear programming?

Linear programming, also known as linear optimization, is a method for achieving the best result in a mathematical model with requirements represented by linear relationships. Linear programming is a special case of mathematical programming.

In linear programming, a solution that does not simultaneously satisfy all constraints is called an infeasible solution.

In some cases, there is no feasible solution area, i.e., there are no points that satisfy all constraints of the problem. An infeasible LP problem with two decision variables can be identified through its graph. For example, let us consider the following linear programming problem.

Minimize z = 200x1 + 300x2

subject to

2x1 + 3x2 ≥ 1200

x1 + x2 ≤ 400

2x1 + 1.5x2 ≥ 900

x1, x2 ≥ 0

The region located on the right of PQR includes all solutions, which satisfy the first and the third constraints. The region located on the left of ST includes all solutions, which satisfy the second constraint. Thus, the problem is infeasible because there is no set of points that satisfies all three constraints.

Hence, a solution that does not simultaneously satisfy all constraints is called an infeasible solution.

Answer: the height is 18 cm.

Step-by-step explanation:

The equation for the volume of a cone is the following: V = 1/3 × B × h, where B (base) = πr². Because we are given the radius of the base, but not the base’s area itself, we will use V = 1/3πr²h.

Here, we are trying to solve for h, the height, so first we can first rearrange the equation to solve for h:

1) V = 1/3πr²h

2) h = V ÷ 1/3πr² (divide both sides by 1/3πr²h)

Now, we just need to input the given values: V = 471, π = 3.14, r = 5

h = 471 ÷ 1/3(3.14)(5²)

= 471 ÷ 1/3(3.14)(25)

= 471 ÷ 1/3(78.5)

= 471 ÷ (78.5/3)

= 18 cm

A firm should record an impairment in the value of property, plant, or equipment by reducing the carrying amount of the asset and recognizing the impairment loss as an expense in the financial statements.

When the value of property, plant, or equipment is impaired, meaning its recoverable amount is lower than its carrying amount, a firm should recognize this impairment in its financial statements. The impairment is recorded by reducing the carrying amount of the asset to its recoverable amount, which is the higher of its fair value less costs to sell or its value in use. The difference between the carrying amount and the recoverable amount is recognized as an impairment loss and recorded as an expense in the income statement. This adjustment reflects the decrease in the value of the asset and allows the firm to accurately report its financial position and performance.

The value of R2 always lies between 0 and 1.The value of R2 represents the proportion of the variation in the dependent variable that can be explained by the independent variables, ranging from 0 to 1.

The value of R2, also known as the coefficient of determination, measures the goodness of fit of a regression model. It represents the proportion of the total variation in the dependent variable that is explained by the independent variables in the model.

R2 ranges between 0 and 1, where 0 indicates that the independent variables have no explanatory power and cannot predict the dependent variable's variation. On the other hand, an R2 value of 1 indicates that the independent variables perfectly explain all the variation in the dependent variable.

An R2 value greater than 1 or less than 0 is not possible because it would imply that the model explains more than 100% or less than 0% of the dependent variable's variation, which is not meaningful. Therefore, the value of R2 always lies between 0 and 1, providing a measure of the model's explanatory power.

Step-by-step explanation:

In inferential statistics, the objective is to determine the probability of the alternative hypothesis being true or the null hypothesis being true.

This involves using sample data to make inferences and draw conclusions about a larger population. By analyzing the data and performing statistical tests, we assess the likelihood of the alternative hypothesis or the null hypothesis being accurate.

The alternative hypothesis represents a claim or statement that contradicts the null hypothesis and suggests that there is a significant relationship or difference between variables. To determine its probability, statistical methods such as hypothesis testing and p-values are employed. These methods evaluate the strength of evidence against the null hypothesis and support the alternative hypothesis when the evidence is substantial.

Answer:

Step-by-step explanation:

Albert:

$1000 earned 1.2% annual interest compounded monthly

= 1000 (1+.001)120

(periodic interest = .012/12 ,n is periods = 10yr x 12 mos)

$500 lost 2% over the course of the 10 years

= 500 (.98)

$500 grew compounded continuously at rate of 0.8% annually

= 500 e^008(10) 10 years interest .008 (in decimal form)

Add these three to see how Albert did with his investments

The balance of Albert is $2159.07; the balance of Marie is $2244.99, the balance of Hans is $2188.35, and the balance of Max is $2147.40. Marie is $10,000 richer at the end of the competition.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

To determine the balance of Albert’s $2000 after 10 years :

If the amount of $1000 at 1.2 % compounded monthly,

A = P(1 +r/n)ⁿ n = 10 years

here P = $1000 and r = 1.2

A = 1000(1 + 0.001)¹²⁰

A = $1127.43

If Albert $500 losing 2%

So 0.98 × 500 = $490

If $500 compounded continuously at 0.8%

So A = P\(e^{rt}\)

A = 500\(e^{0.008\times 10}\)

A = 541.6

So the balance of Albert’s $2000 after 10 years :

Total balance = 1127.43 + 490.00+ 541.64 = $2159.07

To determine the balance of Marie’s $2000 after 10 years:

If 1500 at 1.4 % compounded quarterly,

A = 1500(1 + 0.0035)⁴⁰ = $1724.99

If $500 Marie’s gaining 4 %

So 1.04 × 500 = $520.00

So the balance of Marie’s $2000 after 10 years

Total balance = 1724.99 + 520.00 = $2244.99

To determine the balance of Hans’ $2000 after 10 years:

If $2000 compounded continuously at 0.9%

So A = 2000\(e^{0.009\times 10}\)

A = $2188.3

To determine the balance of Max’s $2000 after 10 years :

If $1000 decreasing exponentially at 0.5 % annually

So A = 1000(1 - 0.005)¹⁰= $951.11

If $1000 at 1.8 % compounded bi-annually

So A = 1000(1 + 0.009)²⁰ = $1196.29

So the balance of Max’s $2000 after 10 years

Total balance = 951.11 + 1196.29 = $2147.40

Therefore, Marie is $10,000 richer at the end of the competition.

The winning jump in the long jump competition is 5.63m.

Complete Question: Sarah competes in a long jump competition.  Her first jump is 4.25m.  Her best jump is 12% more than this.  However her best best jump is 15% lower than the winning jump.  Work out the length of the winning jump.

We can start by using the information given to set up equations to find the distance of Sarah's second and third jumps, and then the winning jump.

We know that Sarah's first jump is 4.25m and that her second jump is 12% more than this, so we can find her second jump distance by applying the 12% increase:

4.25m + (12/100)*4.25m = 4.25m + 0.51m = 4.76m

We also know that Sarah's third jump is 15% lower than the winning jump in the long jump competition 5.63m. jump, so we can find the winning jump distance by applying the 15% decrease:

Winning Jump = 4.76m / (1- 15/100) = 4.76m / 0.85 = 5.63m

So the winning jump in the long jump competition is 5.63m.

Therefore, The winning jump in the long jump competition is 5.63m.

Step-by-step explanation:

This question is written very poorly because it is hard to know what x represents, as well as the end equation. I have come to the conclusion that x represents the amount of days and the end equation represents the exact same equation given (as it asks to rewrite the equation)

So, it is obvious that only one equation matches the one given -- as (1.03)^7 is approximately 1.23, which is close enough to 1.25 (compared to the other options), D is our answer

A and B have both 1.25^7 = around 4.77 (480% ish), and C has 1.03^x, which is not very close to 1.25

The growth of the weed is shown by each day will be f(x) = 197(1.03)⁷ˣ. Then the correct option is D.

Consider the function:

y = a (1 ± r)ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

Initially, there were only 197 weeds at the park. The weeds grew at a rate of 25% each week. The following function represents the weekly weed growth:

f(x) = 197(1.25)ˣ

If the growth of the weed is shown by each day will be given as,

r = 0.25 / 7

r = 0.03

Then the function is given as,

f(x) = 197(1.03)⁷ˣ

The growth of the weed is shown by each day will be f(x) = 197(1.03)⁷ˣ. Then the correct option is D.
