What is the approximate diameter of a sphere with a volume of 113 cm^3
Answer:
B. 6 cm
Step-by-step explanation:
[tex]\text{Take the volume of a sphere and solve for r.}\\V=\frac{4}{3}\pi r^3\\\text{We already know that the volume is 113, so substitute that value.}\\113=\frac{4}{3}\pi r^3\\\text{Divide both sides by 4/3 pi.}\\\frac{113}{\frac{4}{3}\pi}=r^3\\\text{Divide 113 by 4/3 pi.}\\r^3=26.98\\\text{For a more accessible value, round up.}\\r^3 \approx27\\\text{Take the cube root of both sides.}\\r=3[/tex]
Now that the radius is known, all we have to do is multiply it by 2 to get the diameter. Here the answer is simply 3 * 2, or 6.
Answer:
B. 6 cm
Step-by-step explanation:
You can use the formulas [tex]d=(\frac{6V}{\pi } )^{\frac{1}{3} }[/tex] or [tex]d = \sqrt[3]{\frac{6V}{\pi } }[/tex] to solve for diameter using volume. I will use the first forumla for this problem.
1. Substitute 113 for "V":
[tex]d=(\frac{6(113)}{\pi }) ^{\frac{1}{3} }[/tex]
2. Multiply in the parenthesis:
[tex]d=(\frac{678}{\pi } )^{\frac{1}{3} }[/tex]
3. Divide by pi (3.14):
678 ÷ 3.14 = 215.923567
[tex]d=215.9^{\frac{1}{3} }[/tex]
4. Apply the exponent:
d = 5.99907...
d = 6 cm

Yes there is a bias, they are only samplying from one resturant. This resturant could be any type of resturant. the food could be bad or good which wouldnt give us the right info we are looking for. You would want to interview as many customers from as many different resturants in that area.

Write the equation of a quadratic function for which the graph opens in the same direction as the graph of y = x ^ 2 , is wider than the graph of y = x ^ 2 and is shifted up compared to the graph of y = x ^ 2
Answer:
(1/8)x^2 +3
Step-by-step explanation:
in order to widen the quadratic functions you just need to make the coefficient of x^2 less than 1. and to shift the graph upwards you need to add a positive constant at the end like +2.
answer:
(1/8)x^2 +3

Answer:
C ∪ D = (-∞, 2] ∪ (7, ∞)
C ∩ D = Ø (empty)
Step-by-step explanation:
C ∪ D: The union of two sets or intervals is the set of elements which are in either set.
C ∩ D: The intersection of two sets or intervals is the set of elements which are in both sets.
Interval notation symbols
Square brackets [ ]: both endpoints are included in the set.
Round brackets ( ): both endpoints are excluded in the set.
Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.
Square, round [ ): left endpoint is included and right endpoint is excluded in the set.
Given:
C = {x | x ≤ 2} D = {x | x > 7}Therefore,
C = (-∞, 2]D = (7, ∞)Therefore, C ∪ D = (-∞, 2] ∪ (7, ∞)
As x is either equal to or less than 2, or greater than x, there are no elements which are in both sets.
Therefore, C ∩ D = Ø (empty)
An amusement park would like to determine if they want to add in a new roller coaster. In order to decide whether or not they should add the new roller coaster, they poll people at the park to see how many rode the current roller coaster.
As people are leaving the park they randomly sample 600 people.
Out of the 600 people, 400 rode the roller coaster at the park.
Construct a 90% confidence interval to represent the proportion of riders who rode the roller coaster at the park. All conditions for inference have been met.
Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 90% confidence level, hence[tex]\alpha = 0.9[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.
The sample size and the estimate are given by:
[tex]n = 600, \pi = \frac{400}{600} = 0.6667[/tex]
Hence, the bounds of the interval are given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 - 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6350[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 + 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6984[/tex]
The 90% confidence interval is given by: (0.6350, 0.6984).

What is a quadrilateral?A quadrilateral is a polygon with 4 number of sides and 4 vertices. A few examples of a quadrilateral are square, rectangle, rhombus, parallelogram, etc.
Given that ABCD represents a field, therefore, the field is a quadrilateral. Now, as the path is going between the field. And starts from A therefore, it will end at C.
Since It is the same distance from BA and BC. Therefore, it will be the diagonal of the quadrilateral. And as BA and BC are consecutive sides and are of the same length.
Hence, the shape of the field is either square or a rhombus.

what is the equation (x-10)^2
Answer:
Step-by-step explanation:
(x - 10)² is not an equation. It is in factorized form. If you do not mention the equals sign, then that is not an equation. But however, this factorized form can be converted to expanded form using Algberaic formulae. The formulae are,
(a - b)² = a² - 2ab + b², (a + b)² = a² + 2ab + b²
According to the question,
a = x and b = 10
(x - 10)² = x² - 2 (x)(10) + 10²
= x² - 20x + 100
x² - 20x + 100 is the expanded form of (x - 10)².

Answer:
All real numbers
Step-by-step explanation:
We can start out by knowing that the domain of a graph is, the side, to side from the x axis directions.
We can see that the line continues of the graph shown, meaning it is infinite. Meaning the answer is the domain is all real numbers.
We can double check by seeing that the other options don't work or aren't enough:
[tex]x\geq 2\\and\\x\leq 2\\and\\x\geq -4[/tex]
The first wouldn't work becuase, yes that is part of the answer, but not the whole answer. The same goes for the others as well, they are on the line and are correct, but the best, and full answer is "All real numbers"
