How are percents related to rates?

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.

The measure of angle B= 73.739.

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.

There are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then

given:

AC= 24, BC= 25

Now,

The opposite is the side facing the angle while the adjacent is the other third side.

Using Trigonometry

sin B = P/B

sin B= 24/25

sin B= 0.96

B= arc sin(0.96)

B= 73.739

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.

Answer:

5. y = 2x + 4

6. y = (-1/2)x - 2

Step-by-step explanation:

5. We want to find the slope-intercept form of this, which is y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Here, let's take two random points: (-2, 0) and (0, 4). Then we have:

m = (4 - 0) / (0 - (-2)) = 4 / 2 = 2

The slope is thus 2.

The y-intercept is where the line crosses the y-axis. We see it does so at the point (0, 4), so b = 4.

Our equation is thus: y = 2x + 4.

6. Again, let's find the slope. Pick any two points: (-4, 0) and (0, -2). The slope will be:

m = (-2 - 0) / (0 - (-4)) = -2 / 4 = -1/2

Now, look at the point (0, -2); that's where the line crosses the y-axis, so the y-intercept is b = -2.

Thus, the equation is: y = (-1/2)x - 2.

Answer:

5. y = 2x + 4

6. y = -0.5x - 2

Step-by-step explanation:

5. Slope: (4-0)/(0--2) = 4/2 = 2

y-intercept: 4

y = 2x + 4

6. slope: (-2-0)/(0--4) = -2/4 = -0.5

y-intercept: -2

y = -0.5x - 2

Theta =  120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

90  to 870 degrees for theta.

sin (theta) = root(3) /2

We see this comes from a 30-60-90 triangle.

theta is 60 degrees

but we want theta from 90 to 870 degrees.

120 degrees works too.

so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Answer: 15.7

Step-by-step explanation: hope it helps

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.

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
