Answer:

Molly earned $856 on the first day.

Step-by-step explanation:

From the information given, you know that over 3 days Molly earned $2,568 which is:

x+y+z=2568, where:

x is the amount earned on the first day

y is the amount earned on the second day

z is the amount earned on the third day

Also, you know that she earns twice as much money on the first day then the second day, which is: x=2y and that she earns 3 times as much money than the second day on the 3rd day, which is: z=3y.

Now you can replace x and y in the first equation and solve for y:

2y+y+3y=2568

6y=2568

y=2568/6

y=428

No, you can replace the value of y to find x and z:

x=2(428)

x=856

z=3(428)

z=1284

According to this, the answer is that Molly earned $856 on the first day.

The interest for the investment when the rate is 9% gives $101.25

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let y represent the interest, k represent the constant and x represent the rate. Hence:

y = kx

If the interest is $45 when the interest rate is 4%:

45 = 0.04k

k = 1125

y = 1125

When the rate is 9%:

y = 1125(0.09) = 101.25

The interest for the investment when the rate is 9% gives $101.25

Answer :- The value of dzdt at (x, y) = (4, 0) is 0

To find dzdt at (x, y) = (4, 0) given z^3 = x^3 y^2, dxdt = 3, and dydt = 2, follow these steps:

1. Write down the given equation: z^3 = x^3 y^2
2. Differentiate both sides with respect to t (using the chain rule and product rule): 3z^2(dzdt) = 3x^2(dxdt) * y^2 + x^3 * 2y(dydt)
3. Plug in the given values dxdt = 3, dydt = 2, and (x, y) = (4, 0): 3z^2(dzdt) = 3(4^2)(3) * 0^2 + 4^3 * 2(0)(2)
4. Since y = 0, the right side of the equation becomes 0: 3z^2(dzdt) = 0
5. However, we are given z > 0, which means z is not equal to 0. Thus, we can divide both sides by 3z^2: dzdt = 0

So, the value of dzdt at (x, y) = (4, 0) is 0.

Answer:

Step-by-step explanation:

False.

It is not necessary that if the mean of a given dataset is large then the standard deviation has to be large. Mean is the average of all the elements in a dataset and Standard Deviation is the average of deviation of all elements from the mean of the dataset. For instance, take 10 consecutive large numbers, then the mean of the numbers is also large but since the numbers are not widely dispersed, the standard deviation is small in magnitude.

Answer: Trevor's argument will be true if he used 100 minutes.

Let x represent the amount of minutes that Trevor would use for the cost of the phone companies to be the same.

Company A charges $35.25 a month, plus $.11/min for local calls. This means that the total cost of making x minutes of call with Company A's plan is

32.25 + 0.11x

Company B charges $14.25 a month, plus $.32/min for local calls. This means that the total cost of making x minutes of call with Company B's plan is

14.25 + 0.32x

For both costs to be the same, the number of minutes would be

35.25 + 0.11x = 14.25 + 0.32x

0.32x - 0.11x = 35.25 - 14.25

0.21x = 21

x = 21/0.21 = 100

Step-by-step explanation:

The number of visitors to the local art museum is expected to increase by 4% per month over the next 6 months. A function that models the number of visitors to the museum "t" months from now can be represented by the equation: N(t) = 3000 * \((1 + 0.04)^t.\)

To model the number of visitors to the museum "t" months from now, we need to account for the 4% increase in visitors each month. We start with the initial number of visitors, which is given as 3000.

To calculate the number of visitors after 1 month, we multiply the initial number of visitors (3000) by (1 + 0.04), which represents a 4% increase. This gives us 3000 * (1 + 0.04) = 3120.

Similarly, to calculate the number of visitors after 2 months, we multiply the previous number of visitors (3120) by (1 + 0.04) again. This process continues for each month, with each month's number of visitors being 4% greater than the previous month.

Therefore, the function that models the number of visitors to the museum "t" months from now is N(t) = 3000 * (1 + 0.04)^t, where N(t) represents the number of visitors and t represents the number of months from the current time.

Subtraction Property of Equality

Properties of equality can help manipulate literal equations to solve for specific variables.

Subtraction Property of Equality

The subtraction PoE states:

This means if an equivalent quality is subtracted from both sides of an equation, then the equation is still true. In the equation above, 3x is subtracted from both sides of the equation. The subtraction PoE tells us that we are allowed to do this and maintain equality.

Other Properties of Equality

There is a multitude of PoEs including Addition, Multiplication, and Division. All of the properties also state that if an equal operation is done on both sides of an equation, then it is still equal. So, the subtraction PoE applies to all operations. There are also other properties of equality like Reflexive and Transitive that also help to solve literal equations.

To evaluate \(L[t^2 e^{-2t}]\) using the derivatives of transforms, we can apply the formula for finding the Laplace transform of the product of a function and a power of t. Therefore, \(L[t^2 e^{-2t}] = 2/(s + 2)^3.\)

The formula for the nth derivative of the Laplace transform is:

\(L[t^n f(t)] = (-1)^n \frac{d^n}{ds^n} L[f(t)]\)

First, let's find the Laplace transform of \(e^{-2t}:\)

\(L[e^{-2t} ]= 1/(s + 2)\)

Now, we can find the Laplace transform of \(t^2 e^{-2t}\) using the derivatives of transforms:

\(L[t^2 e^{-2t}] = (-1)^2 \frac{d^2}{ds^2} L[e^{-2t}]\)

Differentiating \(L[e^{-2t}]\) twice with respect to s gives us:

\(d^2/ds^2 (1/(s + 2)) = 2!/(s + 2)^3 = 2/(s + 2)^3\)

Therefore, \(L[t^2 e^{-2t}] = 2/(s + 2)^3.\)

The correct description is that moon is waxing.

The theory used in this question is the lunar cycle, which is the process by which the moon changes its shape and illumination over the course of a month.

The waxing phase of the lunar cycle is when the moon is gradually getting bigger and more illuminated.

The waning phase is when the moon is gradually getting smaller and less illuminated.

The moon is waxing:

This is an accurate description because when the moon changes from a new moon to a full moon, it is said to be waxing.

This means that the moon is gradually getting bigger, and its illuminated side is increasing.

This process is called the waxing phase of the moon's cycle.

Answer:

a₈ = 39366

Step-by-step explanation:

The terms have a common ratio between consecutive terms

r = 54 ÷ 18 = 162 ÷ 54 = 3

This indicates the sequence is geometric with nth term

\(a_{n}\) = a₁ \((r)^{n-1}\)

where a₁ is the first term and r the common ratio

Here a₁ = 18 and r = 3 , then

a₈ = 18 × \(3^{7}\) = 18 × 2187 = 39366

Answer:

B

Step-by-step explanation:

Therefore, we can say with 95% confidence interval that the true difference in mean body temperatures between men and women is between -1.144 and -0.056 degrees Fahrenheit.

a) Hypothesis test setup:

Let μ1 be the population mean body temperature of men and μ2 be the population mean body temperature of women.

Null hypothesis: H0: μ1 = μ2 (The mean body temperature is the same for men and women)

Alternative hypothesis: Ha: μ1 ≠ μ2 (The mean body temperature differs for men and women)

We will use a two-sample t-test for independent samples to test this hypothesis.

b) The exact p-value for the two-sample t-test with the given data is 0.0117. This p-value indicates that if the null hypothesis were true, the probability of obtaining a sample as extreme as the observed sample (or more extreme) is 0.0117. Since this p-value is less than the commonly used significance level of 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to indicate that mean body temperatures differ for men and women.

c) To construct a 95% confidence interval for the difference in population means (μ1 - μ2), we can use the following formula:

CI = (x1 - x2) ± tα/2,ν * SE

where x1 and x2 are the sample means for men and women, tα/2,ν is the t-value for the desired confidence level and degrees of freedom (df), and SE is the standard error of the difference in sample means.

Using the given data, we have:

x1 = 97.5, x2 = 98.4

s1 = 0.35, s2 = 0.366

n1 = 8, n2 = 9

df = n1 + n2 - 2 = 15

t0.025,15 = 2.131 (from t-distribution table)

SE = sqrt(s1^2/n1 + s2^2/n2) = 0.126

CI = (97.5 - 98.4) ± 2.131 * 0.126

CI = (-1.144, -0.056)
