Step-by-step explanation:

The interest that will accrue while the college freshman is still in school and over the 6-month grace period for this freshman year loan is, approximately, B. $2,915.06.

The interest for federal college loans is based on the simple interest formula instead of compounding.

By compounding, we mean that interest is computed on the principal and accumulated interest.

Federal Direct Unsubsidized Loan = $15,100

Number of years for college = 4 years

The number of years before repayment = 4.5 years (4 years + 6 months)

Simple interest for 4.5 years = $2,915.06 ($15,100 x 4.29% x 4.5 years)

On the other hand, one can compute the compounded interest using an online finance calculator.

N (# of periods) = 4.5 years

I/Y (Interest per year) = 4.29%

PV (Present Value) = $15,100

PMT (periodic payment) during the 4.5 years = $0

Results:

FV = $18,241.85

Total Interest = $3,141.85

Thus, the interest is Option B.

The most appropriate choice for equation of line in slope intercept form will be given by-

line K is parallel to line P

line M is not parallel to both line K and line P.

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx +c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line

For M

y + 1 = -3(x - 1)

y + 1 = -3x + 3

y = -3x + 3-1

y = -3x + 2

Slope of M = -3

For K

y = 3(x+2)

y = 3x + 6

Slope of K = 3

For P

y + 4 = 3x

y = 3x - 4

slope of P = 3

Since Slope of K = Slope of P,

line K is parallel to line P

Since slope of M is different from slope of both K and P,

line M is not parallel to both line K and line P.

To solve this problem we will need a system of equations.

Step 1. Find the first equation.

Using the statement "Emma rented a bike for 4 hours and paid £18", we will call the cost per hour h, and the flat fee f. Thus, the first equation is:

This is because Emma rented the bike for 4 hours but she had to pay a flat fee f, and the total was £18.

Step 2. Find the second equation.

We do the same but now with the statement "Louise rented a bike for 7 hours and paid £25.5". Remember that for our equation, h represents the cost per hour and f the flat fee. The second equation is:

Step 3. In summary, our system of equations is:

Step 4. To solve part a. we have to find the cost per hour "h".

To find it, we use the elimination method in our system of equations, which consists of adding or subtracting the equations in order to eliminate one variable.

Since we are interested in finding "h", we can subtract the second equation from the first one, and we get the following:

Applying the subtraction:

And we start subtracting 7h-4h, which results in 3h:

The next subtraction is f-f, which results in 0.

And then, subtract 25.5-18:

The equation we have as a result is:

Which is an equation we can use to solve for the cost per hour h.

Dividing both sides by 3:

The cost per hour is £2.5

Step 5. To find part b we need to find the rental feed, in our case, this means to find "h".

Using the first equation of the system:

And substituting the previous result:

We get:

Solving the operations:

And solving for f:

the flat fee is £8.

Step 6. To find part c, we consider the cost per hour and the flat fee.

Michael rented the bike for 2 hours.

Since the cost per hour is £2.5, and the flat fee is £8, he will pay:

Solving these operations:

It will cost £13.

Answer:

a. £2.5

b. £8

c. £13

To find how many miles did she run multiply the miles per day by 6days:

Hello there. To solve this question, we'll simply have to isolate y and plug in the value for x.

Given the equation:

4x - 3y = 8

To rewrite it using the notation y = f(x), subtract 4x on both sides and divide the equation by -3

-3y = 8 - 4x

y = - 8/3 + 4x/3

Now, plug in x = 3 in order to find f(3)

f(3) = -8/3 + 4 * 3/3 = -8/3 + 12/3 = 4/3

Answer:

Each interior angle = 180° -60° = 120°

Step-by-step explanation: We know that the three angles in a triangle, add up to 180°, and all the three angles are 60° in an equilateral triangle. The total number of angles of an enclosed space is 180° (n-2) where in is the number of sides.
A hexagon has six sides, so: s= 180° (6-2)

s= 180° x 4

s= 720°

now since in a regular shape, each interior angle is equal. We just divide the total interior angle with a number of sides

6.

720° divided by 6 is equal to 120°

the hypotenuse of the right angled triiangle = x = 13cm (option A)

Explanation:

Area of B = 144cm²

Area of a square = length²

length = √Area of a square

shape of B is a square, hence the length of B:

the length of one of the side of B = √144 = 12cm

Area of A = 25cm²

shape of A is a square

the length of one of the side of A = √25 = 5cm

Triangle is a right angled-triangle

From the diagram, the length of the side of B = opposite = 12cm

The length of the side of A = adjacent = 5cm

The length of the third square marked x = hypotenuse

Using pythagoras' theorem:

Hypotenuse² = opposite² + adjacent²

x² = 12² + 5²

x² = 144 + 25

x² = 169

x = √169

x = 13cm

Hence, the hypotenuse of the right angled triiangle = x = 13cm (option A)

Remember the formua to calculate the slope of a line between to points

is:

So to calculate the slope of the table, let's use the points

A(0 , 0) and B(30 , 156). Thus,

You can check that this slope works for any consecutive pair of points of the table, since the data is related with a straight line (constant slope)

To get a better sense of what a slope means, let's think about the original units of measurement of the data. Notice that the units for x data is "Miles traveled" and the units for y data is "Gallons of fuel".

In the formula for slope, we divide y data by x data. Therefore, the whole slope, with units of measurement, would be

Thus, the slope of the table would mean the gallons of fuel consumed per each mile traveled

Now, remember the y-intercept occurs when x = 0.

In this case, the y-intercept would be 0, meaning that the plane didn't use any fuel until it started the journey. Perhaps it was parked and with the engines off.

To come up with an equation for the table, lets use the slope we calculated, point A(0 , 0) and the slope-point form of a line, as following:

Answers:

a)

The slope of the table means the gallons of fuel consumed per each mile traveled.

b) The y-intercept is 0. It means the plane didn't use any fuel until it started the journey.

c)

A scatter plot shows a positive correlation when the values of y tend to increase as the values of x increases.

From this scatter plot, we can see that as the values of x increase, the values of y also increase. Therefore, this scatter plot shows a positive linear correlation.

An outlier is the the dot which doesn't fit with other dots or is far away from the rest of the dots. Here, we have one outlier.

Therefore, we can say the scatter plot shows positive linear with one outlier correlation because as the plotted values of x increase, the values of y generally increase.

ANSWER:

The scatter plot shows positive linear with one outlier correlation because as the plotted values of x increase, the values of y generally increase.

We have a parabola with the vertex at (0,0).

If we write the equation in vertex form, we have:

We have to find the value of the parameter a.

As the parabola is concave down, we already know that a<0.

As a<0 and y=a*x^2, the only option that satisfies this condition is y=-1/2*x^2.

Answer: y=-(1/2)*x^2 [Option C]

Answer:

Major axis (0, +-14)

Explanation:

The equation of an ellipse with the center in the origin is:

So, to transform the equation into this form, we need to divide both sides by 784 as:

It means that a² = 16 and b² = 49. So, a = ±4 and b = ±7

Now, the major axis is 2 times the greater value between a and b. Since the greater value is b = 7, 2 times b is:

Major axis = (0, ±7*2) = (0, ±14)

Given data:

The first point on the graph is (-1,0).

The second point on the graph is (0, -1).

The expression fo the equation of the line is,

Thus, the equation of the line is y=-x-1

The probability of birthday being in July is 1/12.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a numeric value and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is flipping a fair (impartial) coin. The chance of either "heads" or "tails" is half because there are only two possible outcomes (heads or tails), and because the coin is fair, both outcomes (heads and tails) are equally likely.

Probability of birthday being in July = 1/12 (12 months in a year)

Given the following function:

Both θ and y are functions of the time (t)

We will find the derivatives of θ and y with respect of the time (t) as follows:

So, the answer will be:

Not necessarily. The least-squares line is the best fit for all the points in the scatterplot. if it so happens that in order to get close to some point on the plot the line has to go a little further away from some other point, the line will be adjusted to accommodate that.

Hence, the least square line does not always pass through at least one point on the line.
