explanation: the equation of the snack shop is y=1.25x while for the sports field it is y=1.30x
1.25 < 1.30
Answer:
The Snack Shop
Step-by-step explanation:
The equation given, y=1.25x means this store sells a bar of granola for $1.25.
The other store sells their granola bar for $1.30.
1.25 is less than 1.30.
Hence, the snack shop sells their granola bars for a lower price.

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.
Answers
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 the approximate diameter of a sphere with a volume of 113 cm^3
Answers
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

what is the equation (x-10)^2
Answers
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.

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.
