The probability that the mean clock life would be greater than 0.4 years is 1

We know,

                mean life = μ = 15

                variance = \(σ^{2}\) =  25

                         which implies σ = 25 = 5

                 Number of samples = n = 41

Event to compute its probability =  X ≥ 0.4

So,

             z = \(\frac{x}{y}\)

where x  = X - μ = 0.4 - 15 = -14.6

and y = σ / √n = 5 / √41 = 0.78

Therefore,

                 z = \(\frac{-14.6}{0.78}\) = -18.7

Using the properties of normal distribution,

         Pr(X ≥ 0.4) = Pr( Z ≥ -18.7)

                            = 1

Therefore,

The probability that the mean clock life would be greater than 0.4 years is 1.

To evaluate the line integral along the path C given by x = 2t, y = 4t, where 0 ≤ t ≤ 1, we can follow these steps:

1. Rewrite the given integral in terms of t using the parameterization of the path: C: x = 2t, y = 4t.
2. Compute the derivatives dx/dt and dy/dt.
3. Substitute the parameterization and derivatives into the line integral.
4. Evaluate the integral over the specified interval.

Step 1:
The integral in terms of t is: ∫(3y² dy)

Step 2:
dx/dt = 2
dy/dt = 4

Step 3:
Substitute the parameterization and derivatives:
∫(3(4t)² * 4 dt) over the interval [0, 1]

Step 4:
Evaluate the integral:
∫(3 * 16t² * 4 dt) from 0 to 1
= 192 ∫(t² dt) from 0 to 1

Now, integrate and evaluate the integral:
= 192 * [1/3 * t^3] from 0 to 1
= 192 * (1/3 * 1^3 - 1/3 * 0^3)
= 64

So, the value of the line integral along the path C is 64.

The most appropriate choice for percentage will be given by

Cost of fencing 1.1 foot = $5.995

Cost of sodding 1.1 sq. foot = $0.715

Total cost of fencing and sodding = $6.71

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

For example- 2% means \(\frac{2}{100}\)

Here,

Cost of fencing 1 foot = $5.45

10% of 1 foot = \(\frac{10}{100}\times 1\)

                     = 0.1 foot

1 foot + 10% of 1 foot = 1 + 0.1 = 1.1 feet

cost of fencing 1.1 foot = $5.45 \(\times\) 1.1 = $5.995

Cost of sodding 1 sq foot = $0.65

Cost of sodding 1.1 sq foot = $0.65 \(\times\) 1.1 = $0.715

Total cost of fencing and sodding = $(5.995 + 0.715)

                                                         = $6.71

Rational number which does the square root of 30 fall is between 5 and 5.5.

A rational number is any number that can be expressed as a ratio (or fraction) of two integers. p/q where q is not equal to 0 is the form of a rational number, which is a sort of real number in mathematics. A rational number is any fraction with a non-zero denominator. 1/2, 1/5, 3/4, and other like numbers are a few examples of rational numbers.

Given,

25 and 36, which are the squares of 5 and 6, respectively, are the perfect squares that are most similar to 30.

Therefore, the square root of 30 will lie between 5 and 6. Additionally, the square root of 30 will be between 5 and 5.5 because it is closer to 25 than it is to 36.

The average temperature of the coffee between t = 0 and t = 10 minutes is approximately 146 degrees.

Option C is the correct answer.

We have,

To find the average temperature of the coffee between t = 0 and t = 10 minutes, we need to calculate the average value of the temperature function F(t) over that interval.

The formula for the average value of a function f(x) over an interval [a, b] is given by:

Average value = (1 / (b - a)) x ∫[a to b] f(x) dx

In this case,

We want to find the average temperature over the interval [0, 10] minutes, so our formula becomes:

Average temperature = (1 / (10 - 0)) x ∫[0 to 10] F(t) dt

To find the integral of F(t), we need to calculate the antiderivative of F(t):

∫ F(t) dt = ∫ \((72 + 118e^{-0.093t}) dt\)

Using the power rule of integration and the fact that the integral of \(e^x\) is \(e^x\), we can evaluate the integral:

∫ F(t) dt =\(72t - (118 / 0.093) \times e^{-0.093t}\)

Now,

Average temperature = (1 / 10) x ∫[0 to 10] F(t) dt

Average temperature = (1 / 10) x (72(10) - (118 / 0.093) x \(e^{-0.093(10)}\) - (72(0) - (118 / 0.093) x \(e^{-0.093(0)}))\)

Simplifying further:

Average temperature = (1 / 10) x (720 - (118 / 0.093) x \(e^{-0.93}\) - 0)

Using a calculator, we find:

Average temperature ≈ 146 degrees

Therefore,

The average temperature of the coffee between t = 0 and t = 10 minutes is approximately 146 degrees.

When multiplying: Numbers multiply with numbers and for the x's, add the exponents

If there is no exponent, you can assume an imaginary 1 is the exponent

2x⁴ (3x³ − x² + 4x)

= 6x⁷ -2x⁶ + 8x⁵

Answer:

A. \(6x^{7} - 2x^{6} + 8x^{5}\)

Label the parts of the expression:

Outside the parentheses = \(2x^{4}\)

Inside parentheses = \(3x^{3} -x^{2} + 4x\)

You must distribute what is outside the parentheses with all the values inside the parentheses. Distribution means that you multiply what is outside the parentheses with each value inside the parentheses

\(2x^{4}\) × \(3x^{3}\)

\(2x^{4}\) × \(-x^{2}\)

\(2x^{4}\) × \(4x\)

First, multiply the whole numbers of each value before the variables

2 x 3 = 6

2 x -1 = -2

2 x 4 = 8

Now you have:

6\(x^{4}x^{3}\)

-2\(x^{4}x^{2}\)

8\(x^{4} x\)

When you multiply exponents together, you multiply the bases as normal and add the exponents together

\(6x^{4+3}\) = \(6x^{7}\)

\(-2x^{4+2}\) = \(-2x^{6}\)

\(8x^{4+1}\) = \(8x^{5}\)

The percent error in estimating the number of students who will try out for the cross-country team is 11.11%.

How to calculate percent error?

Percent error can be calculated by using the following formula:

percent error = ( | estimated value - actual value | / actual value ) x 100,

where |...| indicates the absolute value (the positive difference between the two values).

Ms. Brown estimated 63 students would try out for the cross-country team this year, but 70 students tried out.

Actual value = 70

Estimated value = 63

Using the formula, percent error = (| estimated value - actual value | / actual value) x 100percent

                                              error = (| 63 - 70 | / 70) x 100= 11.11%

Therefore, the percent error is 11.11%.

The data described is a combination of both nominal and ordinal data. In the first round of the spelling bee is nominal data, and in the last round of the spelling bee is ordinal data.

The first round of the spelling bee is nominal data as it is a categorical variable that describes the order in which the participants ranked in that round. The first round did not have a specific rank or order, it was simply a categorical grouping. However, the last round of the spelling bee is an example of ordinal data as it is based on a specific order or rank. The participant came in first place in the last round, which is an example of ordinal data.

Ordinal data is a type of data that represents a specific order or ranking, while nominal data represents a categorical grouping. In the context of the spelling bee, the first round is an example of nominal data because it is simply a grouping of participants who performed in a certain way. In contrast, the last round of the spelling bee is an example of ordinal data because it involves a specific ranking or order that the participants achieved.

As it involves both categorical groupings and specific rankings. Understanding the difference between nominal and ordinal data is important when analyzing and interpreting data, as it can affect the statistical methods and techniques used to analyze the data.

Step-by-step explanation:

√ 26*(26/2)

=√ 26*13 = √ 338 = 13√ 2

The length of the segment  cut from the line by the two other sides of the triangle is \(13\sqrt{2\)

The length of the side is given as:

L= 26 inches

The length (d) of the line that divides the segment is calculated as:

\(d = \sqrt{(L/2)^2 + (L/2)^2\)

So, we have:

\(d = \sqrt{(26/2)^2 + (26/2)^2\)

Evaluate the quotients

\(d = \sqrt{13^2 + 13^2\)

Rewrite the expression as:

\(d = \sqrt{13^2* 2\)

Take the square root

\(d = 13\sqrt{2\)

The estimated change in yy using differentials is -0.00679. This means that if xx is increased by 0.005, then yy is estimated to decrease by 0.00679. The differential of yy is dy=-5sin(5x)dxdy=−5sin⁡(5x)dx. We are given that y=cos(5x)=π/30y=cos⁡(5x)=π/30 and x=0.055x=0.055.

We want to estimate ΔyΔy, which is the change in yy when xx is increased by 0.005. We can use the differential to estimate ΔyΔy as follows:

Δy≈dy≈dy=-5sin(5x)dx
