The average rate of change per hour in the temperature is 0.83 degrees.

To find the average rate of change per hour, we need to divide the total change in temperature by the number of hours over which the temperature changed.

The temperature rose by 5 degrees from 6:00 am to 12:00 pm, which is a period of 6 hours.

Therefore, the average rate of change per hour can be calculated as follows:

average rate of change per hour = total change in temperature / number of hours

So, we have

average rate of change per hour = 5 degrees / 6 hours

average rate of change per hour = 0.83 degrees/hour (rounded to two decimal places)

So, the average rate of change per hour is 0.83 degrees.

Answer:

Step-by-step explanation:

For us,

P = 728,

r = .044,

e is Euler's number (a constant), and

t is 16. Filling in:

\(V=728e^{(.044)(16)}\) and

\(V=728e^{(.704)}\) and

V = 728(2.02182385) so

V = $1471.89

A person places $728 in an investment account earning an annual rate of 4.4%, compounded continuously. The value of the account in t years is $1471.89.

We have given that,

P = 728,

r = 0.044,

e is Euler's number (a constant), and

t = 16.

The formula of the account in t years is,

\(V = Pe^{rt}\)

Use the given value in the above formula,

V = 728(2.02182385)

Therefore we get,

V = $1471.89

Therefore, the value of the account in t years is $1471.89.

The required answers ar(a)P = $2,000,r = 4.5%,n = 2 (b)$ 2985.17, (c) 4.45%

(A) Using the given information, we can identify the following values:

P = $2,000 (the present value or initial deposit)

r = 4.5% (the annual percentage rate)

n = 2 (the number of times per year that interest is compounded, since it is compounded semi-annually)

(B) To find the future value of the account balance after 9 years, we can use the formula:

\(S(t) = P(1 + r/n)^{nt}\)

where t is the time in years. Substituting the given values:

\(S(9) = $2,000(1 + 0.045/2)^{2*9}= $2,000(1.0225)^{18}\)

= $2,000(1.505016)

= $2985.17

Therefore, Monique will have $$2985.17 in the account in 9 years.

(C) The annual percentage yield (APY) takes into account the effect of compounding on the effective interest rate. It is calculated as:

\(APY = (1 + \frac{r}{n})^n - 1\)

Substituting the given values:

\(APY = (1 + 0.045/2)^2 - 1\)

= 0.0445 or 4.45%

Therefore, the annual percentage yield for the savings account is 4.45% rounded to 3 decimal places.

Answer:

x = t(a+p)/4

Step-by-step explanation

Given the expression

​a=4x/t - p

We are to make x the subject of the formula

a=4x/t - p

Add p to both sides

a+p = 4x/t - p+p

a+p = 4x/t

Cross multiply

t(a+p) = 4x

Rearrange

4x = t(a+p)

Divide both sides by 4

4x/4 = t(a+p)/4

x = t(a+p)/4

Answer:

The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.

Step-by-step explanation:

Question 14 explanation: Because each line on the graph represents a different function, that means that the point where they intersect is the answer, as the point both appear on the equations \(y = \frac{1}{2} x+2\) and \(y=x-1\). Since the two equations' point of intersection is (6, 5), that means the solution to the system of equations is the point (6, 5).

Question 15 explanation: The solution to the system of equations \(3x+4y=-2\) and \(2x-4y=-8\) would be the x and y values that satisfy both equations. If you select the pair on selection D, you'll find that it's valid. \(3(-2)+4(1)=-2\) ⇒ \(-6+4=-2\) ⇒ \(-2 = -2\), which is true, so choice D works for the first equation. \(2(-2)-4(1)=-8\) ⇒ \(-4-4=-8\) ⇒ \(-8=-8\), which is also true. This means that x = -2 and y = 1 is the solution to the system of equations, making choice D the correct answer.

            ⇒ with 'x' being the number of child tickets bought

Since the sum of total charge from purchasing adult tickets and total charge from purchasing child tickets is equal to 400:

Step-by-step explanation:

The approximate ordered pair for f(x) = g(x) is given by the intersection between the graphs, it is (4, 22), option a is the correct one.

Here we have the graph of two functions, f(x) and g(x).

To find the ordered pair where f(x) = g(x) (basically we are solving a system of equations), we just need to identify the point on the graph where these two lines intersect.

We can see that it happens for a value of x that is between 0 and 10, and a value of y that is between 20 and 30, the only option that meets that requirements is:

(4, 22)

To solve we need to calculate the z-score, but since we are given the sample size then we shall begin as follows:

The z-score is calculated as (320 - 300)/(50/6) = 2.4, which means that the value of 320 is 2.4 standard deviations above the population mean of 300. Using a standard normal table or calculator, we can find the probability that a standard normal random variable is less than 2.4, which is approximately 0.9918.

This means that the probability that the sample mean is greater than 320 is approximately 0.9918. In other words, there is a 99.18% chance that a randomly selected sample of 36 U.S. Marines will have a mean number of pushups greater than 320.

μ=300, σ=50, n=36, x=320

So,

σ/√n

= 50/√36

= 8.33333

z=(320-300)/8.33333

z=2.4

Therefore,

P(x>320)=P(z<2.4)=0.9918.

What is the solution to an equation?

In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.

y=3x-10 and 2x+3y=3    

                   putting y=3x-10 in 2x+3y=3

          ⇒      2x+3(3x-10)=3

          ⇒      2x+9x-30=3

Irene will require approximately 2.2 repetitions to achieve the "standard" if the standard is 28 minutes per repetition.

To calculate the number of repetitions Irene will require to achieve the standard, we can use the concept of proportional reasoning. We can set up a proportion using the time taken for the initial repetition and the time taken for the next repetition.

Let's define "x" as the number of repetitions Irene will need to achieve the standard. We can set up the proportion as follows:

43 minutes / 1 repetition = 38 minutes / x repetitions

Cross-multiplying and solving for "x" gives us:

43x = 38

x = 38 / 43

x ≈ 0.8837

Since we're looking for a whole number, we need to round up. Therefore, Irene will require approximately 2.2 repetitions to achieve the "standard." Rounding up to the next whole number, she will need 3 repetitions.

Please note that this calculation assumes the time taken for each repetition is consistent and that Irene's performance improves over time. It's also worth considering that additional factors may affect Irene's progress, such as training, experience, and any potential improvements in efficiency.

An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.

In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter. The formula for combination is given by C(n,r)=n!/(r!(n-r)!).
