Write the slope-intercept form of the equation for the line

Answer:

268.08 inches3

Step-by-step explanation:

the volume rounded to the nearest tenth is 268.08 in³.

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume. Volume is another word for capacity.

given the radius of a basketball is 4 inches.

Since basketball has the shape of a sphere,

thus from the general formula of the volume of the Sphere:

Volume = 4/3 πr³

Where r is the radius

in our case

r = 4

Thus volume = 4/3 π 4³

The volume of basketball = 268.08 in³

therefore, the volume of the given basketball is 268.08 in³.

Explanation:

The domain is the horizontal extent of the graph of the function. It is the set of all values of the independent variable for which the function is defined.

In a table or list of (x, y) or (x, f(x)) values the domain is the list of x-values.

On a graph, the domain is the horizontal extent of the graph, excluding any "holes" or vertical asymptotes. (The function is "undefined" at those places.)

__

For a polynomial, the domain is generally "all real numbers."

For rational functions, the domain always excludes any x-values that make any denominator be zero.

For functions such as logarithms or roots, the domain is the set of values for which the function is defined. Even roots (square root, 4th root, ...) are only defined for non-negative numbers. Logarithms are only defined for positive numbers.

__

In some problems, a model is often used that is defined for all values of the independent variable. For example, a height function may be modeled using a quadratic: h(t) = -4.9t^2 +30t +6. This is defined for all values of t, but the "practical domain" is the set of values of t ≥ 0 and before h(t) = 0. That is, we don't care about negative time or negative height.

Answer:

  6120 cm³

Step-by-step explanation:

You want the volume of a rectangular prism 17 cm by 20 cm by 18 cm.

The volume of a rectangular prism is given by the formula ...

  V = LWH

Using the given values for length, width, and height, we find the volume to be ...

  V = (17 cm)(18 cm)(20 cm) = 6120 cm³

The volume of the prism is 6120 cubic centimeters.

Answer:

X = unknown

The highest degree of x is 2 .

Step-by-step explanation:

First of all x is the unknown variable to be determined by solving quadratically

Quadratic equation was chooses because of the degree of x.

The highest degree of x is 2 .

That's the the reason why the value of x will always be double.

If solving linear equation that has degree one, the value of x is one

If solving polynomial, the value of x will be 3 above.

Answer:

2310m^3

Step-by-step explanation:

base area which is the circle = πr^2

But diameter, d = 14, r = 14/2 = 7

area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154

Volume = base area × height

= 154 × 15 = 2310

Answer:

2309.1

Step-by-step explanation:

Deltamath

The equation of a circle is written as (x – h)^2 + (y – k)^2 = r^2

h and k are the center point and r is the radius.

In the given equation h = -6 and k = 7 and r would be the square root of 81, which is 9.

Center (-6,7)

Radius = 9

The required center is [tex](-6,7)[/tex] and the radius is 9 units.

Given equation is,

[tex](x + 6)^2 + (y-7)^2 = 81[/tex]....(1)

Equation of the circle: The general equation of the circle with the center (a,b) and the radius r is represented by,

[tex](x-a)^2+(y-b)^2=r^2[/tex]...(2)

We can write the given equation as,

[tex](x + 6)^2 + (y-7)^2 = (9)^2[/tex]

Comparing equations (1) and (2) we get,

The Centre of the given circle is [tex](-6,7)[/tex]

The radius of the given circle is 9 units.

Step-by-step explanation:

A suitable table or calculator is needed.

One standard deviation from the mean includes 68.27% of the total, so the number of bottles in the range 20 ± 0.16 ounces will be ...

  0.6827·26,000 = 17,750 . . . . . within 20 ± 0.16

__

The number below 1.5 standard deviations below the mean is about 6.68%, so for the given sample size is expected to be ...

  0.66799·26,000 = 1737 . . . . . below 19.76

_____

Comment on the first number

The "empirical rule" tells you that 68% of the population is within 1 standard deviation (0.16 ounces) of the mean. When the number involved is expected to be expressed to 5 significant digits, your probability value needs better accuracy than that. To 6 digits, the value is 0.682689, which gives the same "rounded to the nearest integer" value as the one shown above.

Answer:

  54 yd²

Step-by-step explanation:

The surface area of the prism is the sum of the areas of its faces. Opposite faces have the same area, so we can write the formula as ...

  SA = 2(LW +WH +LH) = 2(LW +H(L +W))

Filling in the numbers, we have ...

  SA = 2(6·3 +1(6 +3)) = 2(18 +9) = 54 . . . . square yards

The area is 54 square yards.

Answer:

The 99% confidence interval for this sample mean is between 2.895 ppb and 2.903 ppb.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 7 - 1 = 6

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 3.7074

The margin of error is:

M = T*s = 3.7074*0.001 = 0.004

In which s is the standard deviation of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 2.899 - 0.004 = 2.895 ppb.

The upper end of the interval is the sample mean added to M. So it is 2.899 + 0.004 = 2.903 ppb.

The 99% confidence interval for this sample mean is between 2.895 ppb and 2.903 ppb.

Answer:

12.57

Step-by-step explanation:

The 5 in the number 10.059 is placed at the hundredth place. i.e. the value of 5 in 10.059 is 0.05. Now, ten times the value of 5 = 10 × 0.05 =  0.5. Let us take 12.57. We see that 5 is placed at the tenths place and has value 10 times the value of 5 in 10.059. Hence, the number comes out to be 12.57.

From what I see in the problem, the expression is

[tex](\frac{3^a^2}{3a^-1} )^k[/tex]

To solve, plug in a and k.

[tex](\frac{3^(5)^2}{3*5^-1} )^-2[/tex]

3*5^2=75

(3*5)^-1 = 1/15

[tex]75 / \frac{1}{15} = 5[/tex]

Step-by-step explanation:

Including the uncertainty, the mass of dog is -

35.7 + 0.1 kg.

We have Mason's Dog.

We have to determine how should Mason express his dog's weight, including the uncertainty.

The uncertainty is the experimenter's best estimate of how far an experimental quantity might be from the true value.

According to the question -

The scale has increments of 0.1 kilograms (kg).

Mason's actual weight - 35.7 kg

Therefore, including the uncertainty, the mass of dog is -

35.7 + 0.1 kg

Hence,  including the uncertainty, the mass of dog is -

Answer:

[tex]\mu_{\hat p}= 0.06[/tex]

[tex] \sigma_{\hat p}= \sqrt{\frac{0.06*(1-0.06)}{280}}= 0.0142[/tex]

And we want to find this probability:

[tex] p(\hat p <0.09)[/tex]

[tex] z = \frac{p \mu_{\hat p}}{\sigma_{\hat p}}[/tex]

[tex] z = \frac{0.09-0.06}{0.0142}= 2.114[/tex]

And we can find this probability:

[tex] P(z<2.114)[/tex]

And using the normal table or excel we got:

[tex] P(z<2.114)= 0.9827[/tex]

Step-by-step explanation:

For this case we have the following info given:

[tex] n = 280[/tex] represent the sample size

[tex] p =0.06[/tex] represent the true proportion

The sample proportion can be approximated with this distribution:

[tex] \hat p \sim N (p ,\sqrt{\frac{p(1-p)}{n}})[/tex]

The mean is given by:

[tex]\mu_{\hat p}= 0.06[/tex]

And the deviation is given by:

[tex] \sigma_{\hat p}= \sqrt{\frac{0.06*(1-0.06)}{280}}= 0.0142[/tex]

And we want to find this probability:

[tex] p(\hat p <0.09)[/tex]

And we can use the z score formula given by:

[tex] z = \frac{p \mu_{\hat p}}{\sigma_{\hat p}}[/tex]

And replacing we got:

[tex] z = \frac{0.09-0.06}{0.0142}= 2.114[/tex]

And we can find this probability:

[tex] P(z<2.114)[/tex]

And using the normal table or excel we got:

[tex] P(z<2.114)= 0.9827[/tex]
