Assume that the normal resting HR range of 70-73 beats per minute applies to the subjects both before and after exercise.

Assume that the average HR of the subjects before exercise falls within this range, then any increase or decrease in average HR with exercise would be relative to this baseline.

The average heart rate (HR) changed with exercise.

We would need to compare the resting HR to the HR after exercise. Without this information, we cannot conclusively determine whether the average HR increased, decreased, or remained the same with exercise.

Assume that the normal resting HR range of 70-73 beats per minute applies to the subjects both before and after exercise.

Assume that the average HR of the subjects before exercise falls within this range, then any increase or decrease in average HR with exercise would be relative to this baseline.

The average HR of the subjects before exercise was 72 beats per minute, and the average HR after exercise was 80 beats per minute.

We could conclude that the average HR increased with exercise. Conversely, if the average HR after exercise was 68 beats per minute, we could conclude that the average HR decreased with exercise.

Without further information about the HR of the subjects before and after exercise.

We cannot determine whether the average HR increased, decreased, or remained the same with exercise.

Step-by-step explanation:

f(x) = 12 × 4^x = 3×4 × 4^x = 3 × 4^(x + 1)

on day 0 (x = 0) the new participants are 3×4 = 12, as each of the 3 founders is sending the message out to 4 friends. so, 12 contacted friends as new participants.

on day 1 (x = 1), the new participants are 3×4×4 = 48, as each of the 12 new participants of day 0 are sending out 4 new messages.

on day 2 (x = 2), the new participants are 3×4×4×4 = 192, as each of the 48 new participants of day 1 are sending out 4 new messages.

and so on.

every new day the number of new participants of the previous day sends out 4 new messages, so, the number of the new participants of the new day is 4 times the number of new participants of the previous day.

so, the result of the previous day is multiplied by 4. and that is multiplied by 4. and that again. and so on.

but the starting value is 12. therefore, we need the 3×4 at the beginning, and we keep it, of course, as the foundation for all the future multiplications by 4.

Magada's loan factor is approximately 0.006367. This means that for every $1 borrowed, Magada will have to pay approximately $0.006367 per month for the next 25 years to repay the loan with an interest rate of 10.75%.

To calculate the loan factor, we first need to calculate the monthly interest rate and the total number of monthly payments.

Monthly interest rate = Annual interest rate / 12

= 10.75% / 12

= 0.8958%

Monthly payments = Number of years * 12

= 25 * 12

= 300

Now, we can use loan factor formula, which is:

Loan factor = [monthly interest rate * (1 + monthly interest rate)^n] / [(1 + monthly interest rate)^n - 1]

Substituting the values, we get:

Loan factor = [0.008958 * (1 + 0.008958)^300] / [(1 + 0.008958)^300 - 1]

= 0.006367

The solution to the given system of equations is x = 5, y = -1.

The system of equations is given as follows:

7x - 2y = 37    ....(i)

4x + y = 19     ....(ii)

To eliminate y, we need to multiply the second equation by 2 so that the coefficients of y in both equations become opposites:

7x - 2y = 37

8x + 2y = 38

Now we can add the two equations together to eliminate y:

15x = 75

x = 5

Now we can substitute x = 5 into equation (ii) to solve for y.

4x + y = 19

4(5) + y = 19

20 + y = 19

The equation of the circle with center at (3,-4) that passes through (-1,-4) is (x - 3)²+ (y + 4)² = 16

The equation of a circle with center (a, b) and radius r is given by:

(x - a)² + (y - b)² = r²

We are given that the center of the circle is (3, -4), so we can substitute a = 3 and b = -4 in the above equation to get:

(x - 3)² + (y + 4)² = r²

We also know that the circle passes through the point (-1, -4).

Substituting this point into the above equation, we get:

(-1 - 3)²+ (-4 + 4)² = r²

16 = r²

The distance from point A to point B is approximately 926.4 feet.

An angle is a measure of the amount of rotation between two lines, rays, or line segments that share a common endpoint, called the vertex. It is typically measured in degrees or radians.

Let's call the distance between point A and the lighthouse "x" and the distance between point B and the lighthouse "y". We want to find the value of "y".

From point A, the crew measures the angle of elevation to the lighthouse to be 6. This means that the angle formed between the horizontal line passing through point A and the line connecting point A to the top of the lighthouse is 6. We can draw a right triangle ABC where point A is the bottom left corner, point B is the bottom right corner, and point C is the top of the lighthouse. The line segment AC represents the height of the lighthouse (111 feet) and the line segment AB represents the distance between point A and the lighthouse (x).

Using trigonometry, we know that:

tan(6) = AC/AB

tan(6) = 111/x

x = 111/tan(6)

Now, from point B, the crew measures the angle of elevation to the lighthouse to be 13. This means that the angle formed between the horizontal line passing through point B and the line connecting point B to the top of the lighthouse is 13. We can draw a right triangle BCD where point B is the bottom left corner, point C is the top of the lighthouse (the same point as in the previous triangle), and point D is the bottom right corner. The line segment CD represents the height of the lighthouse (111 feet) and the line segment BD represents the distance between point B and the lighthouse (y).

Using trigonometry, we know that:

tan(13) = CD/BD

tan(13) = 111/y

y = 111/tan(13)

Therefore, the distance between point A and point B is:

y - x = 111/tan(13) - 111/tan(6)

Using a calculator, we get:

y - x ≈ 926.4 feet

Rounding to the nearest tenth of a foot, the distance from point A to point B is approximately 926.4 feet.

The probability that they run or bike for exercise is 0.91

The probability that a randomly selected executive runs or bikes for exercise can be calculated by adding the probability of running and biking for exercise, subtracting the probability of running and biking for exercise simultaneously (which would be double counted).

This can be expressed mathematically as:

A recent poll of 300 executives revealed how they exercise.

95 reported running, 127 reported biking and 49 reported that they both bike and run for exercise.

If one of these executives is randomly selected, the probability that they run or bike for exercise is 0.91.

This can be calculated by adding the probability of running and biking for exercise, subtracting the probability of running and biking for exercise simultaneously (which would be double counted).

This shows that the majority of executives prefer to exercise by running or biking.

P(Run or Bike for exercise) = P(Run) + P(Bike) - P(Run and Bike)

Plugging in our given values, we get:

P(Run or Bike for exercise) = P(Run) + P(Bike) - P(Run and Bike)

P(Run or Bike for exercise) = 95/300 + 127/300 - 49/300

C = 13.25 + 0.55n.

b) The number of toppings where the cost is the same at either Pizza Palace or Tasty Pizza is 5.

What is a system of equations?

A system of equations is two or more equations solved concurrently.

A system of equations is also called simultaneous equations because the equations are solved at the same time or simultaneously.

                              Pizza Palace    Tasty Pizza

Pizza cost per unit       $11.50             $13.25

Topping cost per unit  $0.90              $0.55

Let the number of toppings = n

Let the total cost for the pizza at each pizza place = c

Equations:

The total cost at Pizza Palace C = 11.50 + 0.9n... Equation 1

The total cost at Tasty Pizza, C = 13.25 + 0.55n... Equation 2

For the total cost, c, to be the same at the pizza places, Equation 1 must equate Equation 2:

That is, C = C.

Substituting the values of C:

11.50 + 0.9n = 13.25 + 0.55n

0.35n = 1.75

n = 5

The given set of side lengths 11, 24, and 26 does not form a right triangle.

To determine whether the set of side lengths form a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we have side lengths 11, 24, and 26. Let's check whether they satisfy the Pythagorean theorem.

Using the theorem, we have:

26^2 = 11^2 + 24^2

Simplifying the right-hand side, we get:

676 = 121 + 576

Therefore, the equation is false, and the set of side lengths satisfies the Pythagorean theorem.

What is equation?

An equation is a mathematical statement which is made by two expressions connected by an equal sign. For example, 3x – 8 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 8.

Let, the cost for 1 movie ticket in Japan = $x

the cost for 1 movie ticket in Switzerland = $y

It would cost $78.40 to buy three tickets in Japan plus two tickets in Switzerland.

So the first equation will be,

3x+2y= 78.40 ------------(1)

Three tickets in Switzerland plus two tickets in Japan would cost $74.05

From this the 2nd equation will be,

2x+3y= 74.05 --------------(2)

Multiplying equation (1) by 2 and multiplying equation (2) by 3 we get,

6x+4y= 156.8 --------------(3)

6x+9y= 222.15 ------------(4)

equation (4)- (3) gives,

5y= 65.35

y= 13.07

What is perimeter of a triangle?

The perimeter of a triangle is the total length of the three sides of the triangle. It is a fundamental geometric concept that is important in many applications, including architecture, engineering, and construction.

To calculate the perimeter of a triangle, you simply add up the lengths of its three sides. This is expressed by the following formula,

Perimeter = side a + side b + side c

where "a," "b," and "c" are the lengths of the three sides of the triangle.

Here Alfonso's error is that he added the three side lengths incorrectly. The correct way to find the perimeter of a triangle is to add up all three sides.

In this case, the three side lengths are 22 cm, 11 cm, and 27 cm. Adding them up, we get,

Step-by-step explanation: In each trial of the reenactment, Scott chooses one card from the stack and records its digit. Based on the given data, a digit of or 1 speaks to a objective scored, and a digit of 2 through 9 speaks to a missed endeavor.

Out of the 5 endeavors per amusement, on the off chance that Scott scores precisely 2 objectives, it implies he missed 3 endeavors. Subsequently, the likelihood of this occasion can be calculated as:

P(exactly 2 objectives) = (0.2)²(0.8)³ = 0.008192

This likelihood can be utilized to discover the anticipated number of diversions in which Scott scores precisely 2 objectives, by duplicating it by the overall number of diversions reenacted:

Anticipated number of recreations = P(exactly 2 objectives) × Add up to number of recreations = 0.008192 × 84 ≈ 0.68

Adjusting to the closest entire number, we get that Scott is anticipated to score precisely 2 objectives in 1 diversion out of the 84 recreated diversions.

The price of each book must be either $38.53 or $10.8 to generate a total sales revenue of $1,24,875.

If the prices of a book is $16 then 10000 copies will be sold.

For every dollar that increase in price, 300 books will not be sold.

So if the price of a book increases $x then the total price of sold books is given by,

y = (16 + x)*(10000-300x)

Now total sales revenue of the books is $124875, that is, y = 124875.

So, (16+x)*(10000-300x) = 124875

160000 + 10000x - 4800x - 300x² = 124875

35125 + 5200x - 300x² = 0

On that particular day, approximately 272.32 BTUs of heat were transferred through the wall.

To calculate the amount of heat transferred through the walls on a particular day, we can use the formula:

Q = U × A × deltaT

where Q is the heat transferred (in BTUs), U is the overall heat transfer coefficient (in BTU/hr·ft^2·°F), A is the area of the wall (in ft^2), and deltaT is the temperature difference between the inside and outside of the wall (in °F).

First, let's calculate the area of the wall. The room has four walls, but we are only interested in the heat transferred through the wall with an R-value of 15. We can calculate the area of this wall as follows:

Area = Length × Height = 13 ft × 9 ft = 117 ft^2

Next, we need to calculate the overall heat transfer coefficient, U. The U-value is the reciprocal of the R-value, so:

U = 1 / R = 1 / 15 = 0.0667 BTU/hr·ft^2·°F

Now we need to calculate the temperature difference between the inside and outside of the wall. We are given that the outside temperature is 36 °F, but we don't know the inside temperature. Let's assume that the inside temperature is 70 °F, which is a typical room temperature. Then the temperature difference is:

deltaT = 70 °F - 36 °F = 34 °F

Finally, we can plug these values into the formula:

Q = U × A × deltaT

Q = 0.0667 BTU/hr·ft^2·°F × 117 ft^2 × 34 °F

Q ≈ 272.32 BTUs

Therefore, on that particular day, approximately 272.32 BTUs of heat were transferred through the wall.
