Answer: We on da same question i do not know

Step-by-step explanation:

The simplification of the given expression will be  \((-3x^2-15x-30)\).

Given expression is

\(-3(x+2)^2 -3+3x\)

By applying  \((a+b)^2=a^2+2ab+b^2\)  we get

\(-3(x^2+6x+9)-3+3x\)

Multiplying by -3 into the whole bracket we get

\(-3x^2-18x-27-3+3x\)

\(-3x^2-18x-30+3x\)

\(-3x^2-15x-30\)

Thus the simplification of the given expression will be  \((-3x^2-15x-30)\)

Step-by-step explanation:

Since, h(x) be an antiderivative of x3+sinxx2+2. if h(5) = π, then,

h(2) = (1/4)(2)⁴ - (1/2)√π erf(2√π/2) + 2(2) + C

In order to find the value of h(2), we can use the given information that h(x) is an antiderivative of the function x³ + sin(x²) + 2 and that h(5) is equal to π. By evaluating h(5), we can determine a relationship between h(x) and x³ + sin(x²) + 2. Then, we can use this relationship to calculate h(2).

To evaluate h(5), we can substitute x = 5 into the expression x³ + sin(x^2) + 2 and integrate it. The antiderivative of x³ is (1/4)x⁴, and the antiderivative of sin(x²) is (-1/2)√π erf(x√π/2), where erf represents the error function. However, since h(x) is an antiderivative of x³ + sin(x²) + 2, the constant term is included as well. So, we have h(x) = (1/4)x^4 - (1/2)√π erf(x√π/2) + 2x + C, where C is the constant of integration.

Given that h(5) = π, we can substitute x = 5 and π into the equation above to obtain π = (1/4)(5)⁴ - (1/2)√π erf(5√π/2) + 2(5) + C. Simplifying the equation, we can solve for C.

Now that we have the value of C, we can determine h(2) by substituting x = 2 into the expression for h(x).

Thus, h(2) = (1/4)(2)⁴ - (1/2)√π erf(2√π/2) + 2(2) + C. Plugging in the known values and the calculated value of C, we can compute the numerical result for h(2).

Answer:

A)

\(P=2x+2\pi r\)

B)

\(x=\frac{1}{2}(P-2\pi r)\)

C)

\(x\approx173\text{ feet}\)

Step-by-step explanation:

So, the track is composed of a rectangle and two semicircles.

The side length of the rectangle is x, and the radius of the semicircles is r.

Part A)

The perimeter is simply the length around the figure.

We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.

So, let's figure out the circumference of the semi-circles. The circumference of a normal circle is:

\(C_{\text{normal}}=2\pi r\)

A semi-circle is half of that. So, we will divide by 2:

\(C_{\text{ semi}}=\pi r\)

We are excluding the diameter from this.

So, our perimeter will be two times x and two times the circumference of a semi-circle (since there are two semi-circles). In other words:

\(P=2(x)+2(\pi r)\)

Simplify:

\(P=2x+2\pi r\)

Part B)

So we acquired the formula:

\(P=2x+2\pi r\)

To solve for x, first, subtract 2πr from both sides. So:

\((P)-2\pi r=(2x+2\pi r)-2\pi r\)

The right side cancels. So:

\(P-2\pi r=2x\)

Multiply both sides by 1/2:

\(\frac{1}{2}(P-2\pi r)=\frac{1}{2}(2x)\)

The right side cancels. So:

\(\frac{1}{2}(P-2\pi r)=x\)

Flip:

\(x=\frac{1}{2}(P-2\pi r)\)

Part C)

So we want to find x when the perimeter is 660 and r is 50 feet. So, substitute them into our formula. We have:

\(x=\frac{1}{2}(P-2\pi r)\)

Substitute 660 for P and 50 for r:

\(x=\frac{1}{2}(660-2\pi (50))\)

Multiply:

\(x=\frac{1}{2}(660-100\pi )\)

Distribute:

\(x=330-50\pi\)

Use a calculator. So:

\(x\approx173\text{ feet}\)

And we're done!

Answer:

\(Y= 120n+635\)

Step-by-step explanation:

Alright!

we are expected to model the total amount of money Myles have\

firstly he has with him $635

and he is earning $120 weekly

Say the number of weeks he worked is given is n

and let the amount of money Myles will have after n weeks be y

hence we can now model the equation to represent how much Myles will have after n weeks

\(Y= 120n+635\)

The expression is same as the equation for a straight line

If I have a two-way between subjects ANOVA with two groups per factor, 2 factors and 4 groups overall in the study.

In a two-way between-subjects ANOVA, the term "two-way" indicates that there are two factors being studied. Each factor has two groups. Therefore, the number of factors is 2, and the number of groups is 4.

The two factors in the ANOVA refer to the independent variables or conditions being manipulated in the study. Each factor has two levels or groups, which are the different conditions or treatment combinations being compared. In total, there are four groups formed by the combinations of the two factors.

Understanding the number of factors and groups is important in interpreting and analyzing the results of the ANOVA. It helps identify the specific independent variables under investigation and the various groups or conditions within each factor. This knowledge is essential for conducting appropriate statistical tests and drawing meaningful conclusions from the study.

Given:

Number of green peas = 475

Number of yellow peas = 193

Let's find the 94% confidence interval to estimate the percentage of yellow peas.

Where:

Total number of peas = 475 + 193 = 668

For the sample proportion, we have:

For a 94% confidence interval, the significance level will be:

1 - 0.94 = 0.06

For the critical value, using the z-table, we have:

Now, to find the 94% confidence interval, apply the formula::

Where:

To find the margin of error E, we have:

Thus, we have:

Hence the confidence interval will be:

Lower limit = 0.2559 ==> 25.59%

Upper limit = 0.3219 ==> 32.19 %

The confidence interval does not contain 0.25, hence we can say that the true results contradicts the expectations.

ANSWER:

The confidence interval does not contain the expectation of 25%, hence, the true results contradicts the expectation.

Step-by-step explanation:

"Rate of change" is the real-world problem way of saying "slope."

So whenever a question asks you to find "rate of change", simply look for the slope.

y = mx + b

e = 3h + 200

mx = slope/rate of change

So, 3 would be your answer.

The magnitude of the vector (3, 9) is 3√10 and the measure of the angle is 71.6°

The cosine of the angle between the vectors and their magnitude are combined to form the dot product.

The dot product is represented by A.B = ABCos θ.

The sine of the angle between the vectors and their magnitude are combined to form the cross-product.

The cross product is represented by A×B = ABSin θ.

We know, The magnitude of a vector (a, b) is √(a² + b²), and the angle it possesses with respect to the positive x-axis is, tan(b/a).

Therefore, The magnitude of the vector (3, 9) is,

= √(3² + 9²).

= √90.

= 3√10.

And the angle is, Ф = tan⁻¹(9/3).

Ф = tan⁻¹(3).

Ф = 71.6°.

0.25 recurring can be expressed as the fraction 25/99.

A fraction is a mathematical expression representing a part of a whole, or a ratio between two numbers. It consists of a numerator, which represents the part or ratio being considered, and a denominator, which represents the whole or total.

To express 0.25 recurring as a fraction, we can use the following method:

Let x = 0.25 recurring

Then 100x = 25.25 recurring (multiply both sides by 100 to move the decimal point)

Subtracting the first equation from the second equation, we get:

100x - x = 25.25 recurring - 0.25 recurring

99x = 25

x = 25/99

Therefore, 0.25 recurring can be expressed as the fraction 25/99.

The linear expression that does not belong with the other three is (x-6)-(-x-10).

The reason is that the other three expressions involve subtracting two terms that are being multiplied by a negative number. In expression a, we have (-5x+3)-(-7x-1), where the second term is the negative of (-7x-1). In expression b, we have ((-3x+3)-(-5x-2)), where the second term is the negative of (-5x-2). In expression d, we have (-7x+2)-(-9x-2), where the second term is the negative of (-9x-2).

However, in expression c, we have (x-6)-(-x-10), where the second term is the negative of (-x-10). This expression does not fit the pattern of the other three, and therefore it is the expression that does not belong.

Step-by-step explanation:

The rejection region for this one-dimensional chi-square test with k = 5 and α = 0.025 is: Chi-square test statistic > C.

To obtain the rejection region for a one-dimensional chi-square test with a null hypothesis concerning k = 5 and α = 0.025, we need to determine the critical chi-square value.

The rejection region for a chi-square test is determined by the significance level (α) and the degrees of freedom (df).

In this case, k = 5 represents the number of categories or groups in the test, and the degrees of freedom (df) for a one-dimensional chi-square test are given by df = k - 1.

Since k = 5, the degrees of freedom would be df = 5 - 1 = 4.

To find the critical chi-square value at α = 0.025 and df = 4, we can refer to chi-square distribution tables or use statistical software.

The critical chi-square value for this test would be denoted as χ^2(0.025, 4).

Let's assume that the critical chi-square value is C.

The rejection region for the test would be the right-tail region of the chi-square distribution beyond the critical value C.

In other words, if the calculated chi-square test statistic is greater than C, we reject the null hypothesis.

So, the rejection region = Chi-square test statistic > C.
