Answer:

D

Step-by-step explanation:

Because of the fact that she opened a savings account and deposited $43 you are going to add that to 16x. Why? Because x represents the number of weeks she deposits $16 in her savings account. The y represents the money in her bank account, which is what we are trying to find.

I hope I've helped! Please leave a Thanks and Vote/Rate.

The correct equation representing the amount of money in Toniqua's bank account after x weeks is y = 43 + 16x. It combines the initial deposit of $43 with the $16 added each week multiplied by the number of weeks.

The question asks for an equation that represents the amount of money in Toniqua's bank account, y, after x weeks. Considering that Toniqua starts with a deposit of $43 and then adds $16 each week, the total amount of money after x weeks would be the initial deposit plus the weekly deposit amount times the number of weeks. Therefore, the correct equation would be:

y = 43 + 16x

The initial deposit is a one-time amount, so it does not multiply by the number of weeks, hence the 43 is not multiplied by x. However, the weekly deposit of $16 does multiply by the number of weeks, which gives us the 16x term in the linear equation.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation y = -4x2 is a parabola that opens downward due to the negative coefficient of the x² term, indicating it has a maximum value. The specific maximum value would depend on the values of x.

The equation y = -4x2 is a quadratic equation. In this case, the coefficient of the x² term is negative, which means the parabola opens downwards. In such situations, the vertex of the parabola represents a maximum value. Hence, y = -4x2 has a maximum value, not a minimum.

To find the actual maximum value, we would need more information, such as values for x. However, unless there are restrictions on the domain, this function does not have a highest maximum value number as it goes towards positive infinity on the y-axis. Instead, we refer to the maximum point being the peak of the parabola, where it turns from increasing to decreasing.

To solve the equation 3tan^2 = sqrt3 tanx for all real values of x, divide both sides of the equation by tan(x) and then take the inverse tangent of both sides. The solutions for x are 30°, 210°, 390°, ...

To solve the equation 3tan^2 = sqrt3 tanx for all real values of x, we can start by rearranging the equation. Divide both sides of the equation by tan(x) to get:

3tan(x) = sqrt3

Next, divide both sides of the equation by 3 to get:

tan(x) = sqrt3/3

Now, we need to find the values of x where the tangent function equals sqrt3/3. We can use the inverse tangent function to find the angles. Taking the inverse tangent of both sides gives:

x = arctan(sqrt3/3)

Then, we can simplify the expression:

x = 30° + n * 180°

Answer:

Im going to go with C.

Step-by-step explanation:

I think that is correct.

The correct answer is C) 105°.

The sum of the angles in a triangle is 180 degrees. Since we know the measures of two of the angles, we can find the measure of the third angle by subtracting the sum of the first two angles from 180 degrees.

In this case, m∠X + m∠Y = 55° + 75° = 130°.

Therefore, m∠W = 180° - 130° = 50°.

However, the diagram shows angle W as an exterior angle of the triangle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles. In this case, the remote interior angles are ∠X and ∠Y.

Therefore, m∠W = m∠X + m∠Y = 55° + 75° = 130°.

Answer Choice Explanation:

A) 20° is too small.

B) 35° is too small.

C) 105° is correct.

D) 130° is too large.

Therefore, the correct answer is C) 105°.

Step-by-step explanation:

The probability that Jaime eats a cherry flavored jellybean first and a green apple flavored jellybean second, for the given condition, is given by: Option D: 5/78

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For two events A and B, by chain rule, we have:

[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(B|A)[/tex]

where P(A|B) is probability of occurrence of A given that B already occurred.

For this case, we're specified that:

Let we take:

A = event that the first jellybean he chose is cherry flavored.

Then, as there are 10 ways to choose a cherry flavored jellybean, and 40 ways to choose a single jellybean randomly, so we get:

n(A) = 10, and n(choosing a random jellybean from a bag of 40 jellybean) = 40

Thus, we get: P(A) = 10/40 = 1/4 = 0.25

Now, let we take B = event that after eating first jellybean (first can be of any flavor), the second jellybean he eats is of green apple flavored.

For second random picking, there are only 39 jellybeans remaining.

P(B|A) = Probability that the second jellybean chosen is green apple flavored given that the first jellybean was cherry flavored.

Since if first jellybean was cherry flavored, so there are still 10 green apple flavored jellybean.

Thus, P(B|A) = 10/39

Using the chain rule, we get:

P(First jellybean is cherry flavored and second jellybean is green apple flavored) = [tex]P(A \cap B) = P(A)P(B|A) = \dfrac{10}{40} \times \dfrac{10}{39} = \dfrac{10}{156} = \dfrac{5}{78}[/tex]

Thus, the probability that Jaime eats a cherry flavored jellybean first and a green apple flavored jellybean second, for the given condition, is given by: Option D: 5/78

Final answer:

To calculate how much lower Ashlee's monthly payment will be if she purchases the points, we first need to calculate her monthly payment with and without the points. Ashlee will make a 20% down payment on the $125,000 home. By purchasing the points, Ashlee will lower her interest rate by 2%. The difference in monthly payments is approximately $115.44.

Explanation:

To calculate how much lower Ashlee's monthly payment will be if she purchases the points, we first need to calculate her monthly payment with and without the points.

1. Calculate the loan amount: Ashlee will make a 20% down payment on the $125,000 home, which is $25,000. So, the loan amount will be $125,000 - $25,000 = $100,000.

2. Calculate the monthly payment without the points: Using the loan amount of $100,000, the interest rate of 4.75%, and the loan term of 30 years, we can use a mortgage calculator to find the monthly payment. The monthly payment without the points is approximately $522.62.

3. Calculate the monthly payment with the points: Ashlee is considering purchasing 2 points. Each point is equal to 1% of the loan amount, so 2 points would be 2% of $100,000, which is $2,000. By purchasing the points, Ashlee will lower her interest rate by 2% to 4.75% - 2% = 2.75%. Using the loan amount of $100,000, the new interest rate of 2.75%, and the loan term of 30 years, we can again use a mortgage calculator to find the monthly payment. The monthly payment with the points is approximately $407.18.

4. Calculate the difference in monthly payments: The difference in monthly payments is $522.62 - $407.18 = $115.44. Therefore, Ashlee's monthly payment will be approximately $115.44 lower if she purchases the points.

Ashlee's monthly payment would be approximately $50.44 lower if she purchases 2 points.

1. Calculate the loan amount after the down payment:

Down payment amount = 20% * $125,000 = $25,000

Loan amount = $125,000 - $25,000 = $100,000

2. Calculate the monthly payment without buying points:

Convert the interest rate to a decimal: 4.75% = 0.0475

Number of months in the loan term: 30 years * 12 months/year = 360 months

Use a mortgage calculator or the following formula to calculate the monthly payment:

Monthly payment = (Loan amount * Interest rate * (1 + Interest rate)^Number of months) / ((1 + Interest rate)^Number of months - 1)

3. Calculate the cost of buying 2 points:

Each point typically costs 1% of the loan amount.

Cost of 2 points = 2 points * 1% * $100,000 = $2,000

4. Calculate the reduced interest rate with points:

Each point usually reduces the interest rate by 0.25%.

Reduced interest rate = Original interest rate - Points reduction * Number of points

Reduced interest rate = 0.0475 - 0.0025 * 2 = 0.0425

5. Calculate the monthly payment with points:

Use the same formula as in step 2 but with the reduced interest rate.

6. Calculate the difference in monthly payments:

Difference = Monthly payment without points - Monthly payment with points

Example calculation:

Let's assume the monthly payment without points is $522.62 (calculated using a mortgage calculator) and the monthly payment with points is $472.18.

Difference in monthly payment = $522.62 - $472.18 = $50.44

Therefore, Ashlee's monthly payment would be approximately $50.44 lower if she purchases 2 points.

Ratio = 2πr/2r = π

Thus ratio comes out to be 'π'

Answer:

The situations that show strong correlation are;

1), 3), 4)

Step-by-step explanation:

To answer the question, we analyze each of the options in turn as follows

1) Since the speed of a car is given by the distance covered per unit time or speed = distance/time then, speed is inversely proportional to time that is an increase in speed will lead to a decrease in time to cover a given distance hence there is a strong correlation implying causation

2) Here, we have that the profit of the company is the difference between the total revenue and the total cost hence;

Profit = Revenue - Cost

As advertising is a cost, increasing the advertising budget, increases the cost and where the revenue remains, constant the profit will decrease

Therefore there is no correlation between increasing the advertising budget and increase in profit

3) When the weather is hot, people get thirsty and will like to cool down their body temperature, hence more people buy ice cream to cool down and quench some thirst hence there is a strong correlation between increase in temperature and an increase in ice cream sales which implies  causation

4) For very low income employments, some employees seek excuses to try to make the most of their time hence whereby it is difficult to have another employee stand in for them, some employees may select the recognized excuse of being sick so as to explain absence from work, hence when the salary is increased, they will find more reasons to come to work hence there is a strong correlation between increase in salary and decrease in sick days.
