The fastest way to find the missing endpoint is to determine from the known endpoint to the midpoint and then performing the same transformation on the midpoint.

I'm going to try to let you answer this yourself so you can learn for yourself ok. :3

You want to find the volume of the solid obtained by rotating about the x-axis the region under the curve y = x 1 / 6 y=x1/6 fro

Natasha2012 [34]

Answer:

Area = πr², where "r" is some distance "y" and/or the function "(1/6)x"; depending on the situation

Step-by-step explanation:

If I'm picturing this correctly, you'll have conical shape after revolving the function about the x-axis. If you took some generic slice and wanted to find the area of the resulting cross-section, then you would have a circle whose radius is some arbitrary value of the line that matches the slice.

For example:

y = (1/6)x right?

If you took a slice at x = 2, then the radius of the resulting cross-sectional circle would be equal to y = (1/6)•2 =1/3.

From here you just plug it into the area of a circle, πr², to get an area of π/3.

Except with an integral you need to take all the points on the interval, so the radius comes out to be the function itself.

Assuming your integral is in terms of dx, r=y. But in order to integrate in terms of dx you must replace "y" with its function (1/6)x. So ultimately r=(1/6)x and Area = π(1/6)x.

A botanist wishes to estimate the mean number of seeds for a certain fruit. She samples 11 specimens and finds the average numbe

Aliun [14]

Answer:

a)The 98% of confidence intervals are

Lower bound of CI = 47 -3.82436 = 43.1756

Upper bound of CI = 47 + 3.82436 = 50.8243

b) The conditions are required for the validity of the interval

A) μ known

Step-by-step explanation:

Explanation:-

The given sample size is 'n' =11

Given the average number of seeds is 47 with a standard deviation of 7

Sample mean (x⁻) = 47

Standard deviation (S) = 7

The 98% of confidence intervals are

$(x^{-} - t_{0.02} \frac{S}{\sqrt{n} } , x^{-} + t_{0.02}\frac{S}{\sqrt{n} } )$

$(47 - t_{0.02} \frac{7}{\sqrt{11} } , 47+ t_{0.02}\frac{7}{\sqrt{11} } )$

The degrees of freedom = n-1 =11-1 =10

t₀.₀₂= 1.812 ( from t - table)

now the intervals are

$(47 - 1.812 \frac{7}{\sqrt{11} } , 47+ 1.812\frac{7}{\sqrt{11} } )$

Lower bound of CI = 47 -3.82436 = 43.1756

Upper bound of CI = 47 + 3.82436 = 50.8243

The conditions are required for the validity of the interval

A) μ known

Explanation:-

If a random sample xi of size 'n' has been drawn from a normal population with a specified mean (μ) known.

The limit for (μ) is given by

$(x^{-} - t_{0.02} \frac{S}{\sqrt{n} } , x^{-} + t_{0.02}\frac{S}{\sqrt{n} } )$

Use any method to solve the equation. If necessary, round to the nearest hundredth. 9x^2 = 17

irina [24]

Answer:

1.37

Step-by-step explanation:

First, we want to isolate the variable x. Do this by dividing both sides by 9:

$\frac{9x^2}{9} =17/9$

$x^{2} =17/9$

Now, square root both sides:

$\sqrt{x^2}= \sqrt{17/9}$

x = $\sqrt{17/9} =\sqrt{17}/3$

Finally, we can use a calculator to finish off the problem:

x = $\sqrt{17}/3$ ≈ 1.37

Hope this helps!

Help me i can’t do this

DerKrebs [107]

Answer:

$\huge\boxed{\sf Star = 14}$

Step-by-step explanation:

Let snowman be x , star be y and shopping bag be z.

So, the given equations are:

1) x + y = 20 (Eq. 1)

2) z = x + x

z = 2x (Eq. 2)

3) z + x = 18 (Eq. 3)

Put Eq. (2) in Eq. (3)

2x + x = 18

3x = 18

Divide both sides by 3

x = 18 / 3

x = snowman = 6

Now, Put x in (Eq. 1)

6 + y = 20

Subtract 6 to both sides

y = 20 - 6

y = 14

So,

Star = 14

$\rule[225]{225}{2}$

Hope this helped!

(5, 10.5) and (25, 12.5 slope

saul85 [17]

Answer:

Step-by-step explanation:

slope = (difference of y-coordinates)/(difference of x-coordinates)

= (12.5-10.5)/(25-5)

= 2/20

= 1/10
