Answer:

If the correlation coefficient is 1, then the slope must be 1 as well.

Step-by-step explanation:

Coefficient of correlation is used in statistics to determine the relationship between two variables. Correlation coefficient and slope always have same sign. It measures the strength of linear relation between two variables. The values of correlation coefficient ranges between 0 to 1. where 0 determines that there is no relationship between two variables.

Answer:

1. Y= 7t^5 +C

2. Y= 35/12x^(12/7)+C

Step-by-step explanation:

The general solution will be determined by integrating the equations as the integration is a simple integration.

For dy/dt = 35t^4

The general solution y

= integral (35t^4)dt

The general solution y

=( 35/(4+1))*t^(4+1)

= 35/5t^5

= 7t^5 +C

To prove by differentiating the above.

Y= 7t^5 +C

Dy/Dt= (5*7)t^(5-1) +0

Dy/Dt= 35t^4

For dy/dx = 5x^(5/7)

Y=integral 5x^(5/7)Dx

Y= 5/(5/7 +1)*x^(5/7+1)

Y= 5/(12/7) *x^(12/7)

Y= 35/12x^(12/7)+C

To prove by differentiating

Y= 35/12x^(12/7)+C

Dy/Dx= (35/12)*(12/7) x^(12/7-1) +0

Dy/Dx=(35/7)x^(5/7)

Dy/Dx= 5x^(5/7)

Step-by-step explanation:

Answer:

4 inches.

Step-by-step explanation:

The formula for the volume of a pyramid is v=1/3bh.

V is the volume of the shape

1/3 is just a rational number or fraction.

b is the area of the base shape of the 3d shape

h is the height of the shape (slant height).

The general formula for the volume of all shapes is V=Bh

V is the volume

B is the area of the base

h is the height of the prism.

In this case, we have a pyramid, so let's use the formula V=1/3Bh.

We know what the volume so 48=?

We can put 1/3 so 48=1/2 times ? times ?.

The base shape of this pyramid is a square, and it has an edge of 6 inches. We need to find the area of that square because it is the area of our base. the formula for finding the area of a square is A=S squared.

A is the area of the shape

S is the side length.

The reason why it is squared is because all sides of a square are equal to each other. Since the base edge is 6 inches, the other edges are 6 inches as well. There are 4 edges in a square.

A= 6 times 6.

A=36.

We have the area of the base, so we can put 48=1/3 times 36 times ?.

We are finding what the slant height is, so let's put the letter "h" to represent the slant height.

Now, 48=1/3 times 36 times h.

All we have to do is solve for h.

First we have to simplify one side of the equation.

To simplify, we have to do 1/3 times 36, or you can do 36 divided by 3. It is your choice. 36 divided by 3 is 12.

Now we have 12h=48.

Isolate h by dividing both sides by 12. 12h divided 12 is h. 48 divided by 12 is   4.

Therefore h=4 inches. The reason we divide both sides is because we have to do the inverse operation of the original equation. For instance 12h=48. To get to 48, you do 12 times h. We take the inverse (opposite) operation of multiplication (division). That will isolate for h.

The slant height of this square pyramid is 4 inches.

Hope this helps. Have a good rest of your day!

The slant height of the pyramid is 4 inches. Therefore, the option B is the correct answer.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, volume of square right pyramid = 48 cubic inches and base edge measuring 6 inches.

We know that, the volume of square based pyramid =a²h/3.

Here, a=6 inches and h=slant height

Now, 48= (6²×h)/3

48=36h/3

48=12h

h=4 inches

Therefore, the option B is the correct answer.

Answer:

[tex]A +B+C+D = 3[/tex] is the correct answer.

Step-by-step explanation:

Given:

[tex]$\frac{5}{2+\sqrt{6}}$[/tex]

To find:

[tex]A+B+C+D = ?[/tex] if given term is written as following:

[tex]$\frac{A\sqrt{B}+C}{D}$[/tex]

Solution:

We can see that the resulting expression does not contain anything under [tex]\sqrt[/tex] (square root) so we need to rationalize the denominator to remove the square root from denominator.

The rule to rationalize is:

Any term having square root term in the denominator, multiply and divide with the expression by changing the sign of square root term of the denominator.

Applying this rule to rationalize the given expression:

[tex]\dfrac{5}{2+\sqrt{6}} \times \dfrac{2-\sqrt6}{2-\sqrt6}\\\Rightarrow \dfrac{5 \times (2-\sqrt6)}{(2+\sqrt{6}) \times (2-\sqrt6)} \\\Rightarrow \dfrac{10-5\sqrt6}{2^2-(\sqrt6)^2}\ \ \ \ \ (\because \bold{(a+b)(a-b)=a^2-b^2})\\\Rightarrow \dfrac{10-5\sqrt6}{4-6}\\\Rightarrow \dfrac{10-5\sqrt6}{-2}\\\Rightarrow \dfrac{-5\sqrt6+10}{-2}\\\Rightarrow \dfrac{5\sqrt6-10}{2}[/tex]

Comparing the above expression with:

[tex]$\frac{A\sqrt{B}+C}{D}$[/tex]

A = 5, B = 6 (Not divisible by square of any prime)

C = -10

D = 2 (positive)

GCD of A, C and D is 1.

So, [tex]A +B+C+D = 5+6-10+2 = \bold3[/tex]

Answer:

16 km

Step-by-step explanation:

From Washington, as the question asks, will now be considered 0 aka the starting point.

So as of now, we know Washington from Oakdale is 6.2 km.

And from Stanford to Salem is 11.9 km, also Salem to Washington is 10.3 km. Hence the addition of 11.9 km and 10.3 km to figure out the whole distance between Stanford and Washington.

11.9 km + 10.3 km = 22.2 km

Now we subtract 22.2 km to 6.2 km for the product of 16 km.

Five-number summary in ascending order: [tex] 0.58, 0.89, 0.98, 1.26, 1.42 [/tex]

Step-by-step Explanation:

The number summary, in ascending order, includes the minimum value, maximum value, median value, upper quartile and lower quartile.

To find each of the above values, first, order the data set in ascending order. Our values given, when ordered, would be:

0.58, 0.59, 0.89, 0.96, 0.97,| 0.98|, 1.07, 1.14, 1.26, 1.28, 1.42

1.The minimum value (the least value or lower value in the given data set).

From the ordered data set, minimum value = 0.58

2. The maximum value is the highest value in the data set = 1.42

3. Median value is the middle value of the data set. The middle value is the 6th value = 0.98.

The median value divides the data set into lower and upper region, as shown below.

0.58, 0.59, 0.89, 0.96, 0.97,|0.98|, 1.07, 1.14, 1.26, 1.28, 1.42

4. Lower Quartile (Q2) is the middle value of the lower region = 0.89, as shown below,

0.58, 0.59, [0.89], 0.96, 0.97,|0.98|, 1.07, 1.14, 1.26, 1.28, 1.42

5. Upper Quartile (Q3) is the middle value of the upper region = 1.26, as shown below.

0.58, 0.59, 0.89, 0.96, 0.97,|0.98|, 1.07, 1.14, [1.26], 1.28, 1.42

: this is the middle value of lower region, after our median divides the data set into two.

0.58, 0.59, 0.89, 0.96, 0.97,|0.98|, 1.07, 1.14, 1.26, 1.28, 1.42

Therefore, the five-number summary in ascending order is as follows: [tex] 0.58, 0.89, 0.98, 1.26, 1.42 [/tex]

Min = 0.58

Q1 = 0.89

Median = 0.98

Q3 = 1.26

Max = 1.42

A = 59.63cm^2

Step-by-step explanation:

You have the following function for the surface area of the container:

[tex]A=\pi r^2+\frac{100}{r}[/tex]                (1)

where r is the radius of the cross sectional area of the container.

In order to find the minimum surface are you first calculate the derivative of A respect to r, to find the value of r that makes the surface area a minimum.

[tex]\frac{dA}{dr}=\frac{d}{dr}[\pi r^2+\frac{100}{r}]\\\\\frac{dA}{dr}=2\pi r-\frac{100}{r^2}[/tex]         (2)

Next, you equal the expression (2) to zero and solve for r:

[tex]2\pi r-\frac{100}{r^2}=0\\\\2\pi r=\frac{100}{r^2}\\\\r^3=\frac{50}{\pi}\\\\r=(\frac{50}{\pi})^{1/3}[/tex]

Finally, you replace the previous result in the equation (1):

[tex]A=\pi (\frac{50}{\pi})^{2/3}+\frac{100}{(\frac{50}{\pi})^{1/3}}}[/tex]

[tex]A=59.63[/tex]

The minimum total surface area is 59.63cm^2

Answer:

A.) Even.

Step-by-step explanation:

If a function is an even function, then

F(-x) = f(x)

Also, if a function is an odd function, then, f(-x) = -f(x)

You are given the below function

f(x) = 1 + 3x^2 − x^4

Let x = 2

Substitute 2 for x in the function

F(x) = 1 + 3(2)^2 - (2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Also, Substitute -2 for x in the function

F(x) = 1 + 3(-2)^2 - (-2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Since f(-x) = f(x), we can conclude that

F(x) = 1 + 3x^2 - x^4 is even

Substitute the value of T in the above formula.

[tex]\omega=\frac{2\pi}{\frac{1}{1.6}}\\\omega=3.2\pi[/tex]

If the center of the wheel is at the origin then for [tex]t=0[/tex] the rest position is [tex]-a[/tex].

This can be written as:

[tex]h(t)=-a\cos(\omega t)\\h(t)=-82.5cos(32.\pi t)[/tex]

The actual height of the rider from the ground is:

[tex]h(t)=\text{ Initial height from bottom}+\text{ radius}-82.5\cos(3.2\pi t)\\h(t)=15+82.5-82.5\cos(3.2\pi t)\\h(t)=97.5-82.5\cos(3.2\pi t)[/tex]

[tex]0.51 - 1.96 \sqrt{\frac{0.51(1-0.51)}{557}}=0.468[/tex]

[tex]0.51 + 1.96 \sqrt{\frac{0.56(1-0.56)}{1507}}=0.552[/tex]

And the 95% confidence interval would be given (0.468;0.552).

Step-by-step explanation:

The estimated proportion of people who say that were underpaid is given by:

[tex]\hat p=\frac{284}{557}=0.510[/tex]

The confidence interval would be given by this formula

[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

For the 95% confidence interval the value of [tex]\alpha=1-0.95=0.05[/tex] and [tex]\alpha/2=0.025[/tex], with that value we can find the quantile required for the interval in the normal standard distribution.

[tex]z_{\alpha/2}=1.96[/tex]

And replacing into the confidence interval formula we got:

[tex]0.51 - 1.96 \sqrt{\frac{0.51(1-0.51)}{557}}=0.468[/tex]

[tex]0.51 + 1.96 \sqrt{\frac{0.56(1-0.56)}{1507}}=0.552[/tex]

And the 95% confidence interval would be given (0.468;0.552).
