Answer:
A. $213.75
Step-by-step explanation:
If we add up all the numbers listed, we get a sum of 2565.
Divide $2,565 by how many numbers we added. We added 12 numbers.
2,565 ÷ 12 = 213.75.
Therefore, the average is $213.75.

Answer:
I believe that it is the 3 option Im not 100% sure but im most certain
Step-by-step explanation:
A sample of restaurants in a city shows that the average cost of an appetizer is $6.32 with a standard deviation of $0.47. A brand new restaurant wants to get noticed by offering appetizers for a much lower price. To determine the lower price, should the formula use a z-value that is greater than or less than -1?
a.
Greater than -1
c.
Greater than 1
b.
Less than -1
d.
Either way, it doesn’t matter
Answer:
D
Step-by-step explanation:
Is the corrext answer hope it helps
By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.
Option B is the correct answer.
What is a standard deviation?Standard deviation is a measure of the amount of variability or spread in a set of data.
It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.
We have,
The z-value formula is used to determine the number of standard deviations a data point is from the mean.
To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.
Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.
Recall that the z-value formula is:
z = (x - μ) / σ
where x is the value of interest, μ is the mean, and σ is the standard deviation.
Thus,
By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

The histogram that best represents the data is the first histogram.
What is an histogram?An histogram is a graph that shows the number of times each element of x was observed.
here, we have,
For this problem, we have that the data-set is given by:
3.4 1.1 1.7 3.1 5.8 3.2 3.7 3.4 1.6 3.5 3.9 3.8 1.1 1.9 1.8.
We divide the data-set into ranges, hence the number of elements in each range is given as follows:
6 students download between 0 and 2 songs per week.
8 students download between 2 and 4 songs per week.
1 student download between 4 and 6 songs per week.
Hence the first histogram best represents the data.

Two trains leave New York at the same time. One travels south 50 miles per hour and the other traveled east at 40 miles per hour. How far apart are they at the end of THREE HOURS?
Answer:
192 miles
Step-by-step explanation:
This is a right triangle problem
One leg of the triangle is
50 * 3 = 150
The other leg is
40 * 3 = 120
the distance is the hypotenuse
c^2 = 150^2 + 120^2
c^2 = 22500 + 14400
c^2 = 36900
Take the square root of both sides
c = 192.093727123
c ≈ 192 miles
Answer:
30 miles apart
Step-by-step explanation:
Im not sure if this is the corect answer to this but this is what i think what i did was get 50 x 3 and 40 x 3 since they starded at the same times and finished after 3 hours so multiply your numbers by 3 so...
50 x 3=150
40 x 3=120
150-120=30 miles apart

What are the lateral area and the surface area of the cone shown below? Round the answers to
the nearest tenth. The figure is not drawn to scale.
Answer:
lateral surface area of the cone = 829.0ft²
Hence the total surface area is 1,208.9ft²
Step-by-step explanation:
lateral surface area of the cone = πrl
l is the slant side = 24ft
r is the radius = 11ft
lateral surface area of the cone = π(11)(24)
lateral surface area of the cone = 3.14 * 264
lateral surface area of the cone = 828.96ft²
lateral surface area of the cone = 829.0ft²
Total surface area = πr(r+l)
r is the radius = 11ft
l is the slant side = 24ft
Total surface area = π(11)(11+24)
Total surface area = π(11)(35)
Total surface area = 3.14 * 385
Total surface area = 1,208.9ft²
Hence the total surface area is 1,208.9ft²

15) ? = 180° -55° = 125°
16) ? = 180° - 80° = 100°
_____
Additional comment
The quadrilateral formed by the tangents and the radii to the points of tangency has a total interior angle measure of 360°. The angles where the radii meet the tangents are 90°, so the sum of the external angle and the central angle is 360° -90° -90° = 180°. That is, the external angle and the central angle are supplementary.

At the end of Evan's party, there were 1 1 pizzas left. Evan ate į pizza for lunch the next day. What fraction of a pizza was left after Evan's lunch? Move numbers to the boxes to complete the equation. PLEASE HELP WILL GIVE BRAINLIEST
So, after Evan's lunch, there was 7/8 quantity of pizza left.
Here we can write,
The simple fraction of [tex]1\frac{1}{8}[/tex] = 9/8
So, if there were 9/8 pizzas left at the end of the party and Evan ate 2/8 of a pizza for lunch,
we can start by subtracting the amount that Evan ate from the total amount that was left,
⇒ 9/8 - 2/8
To subtract fractions with like denominators,
We can simply subtract the numerators and keep the same denominator,
⇒ 9/8 - 2/8 = 7/8
So, after Evan's lunch, there were 7/8 of a pizza left.

Amy knits 1/10 of a scarf in 4/5 of an hour. What fraction of scarf can Amy knit in 1 hour
Answer:
Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
We have that:
1/10 of a scarf - 4/5 of an hour
x of a scarf - 1 hours.
Applying cross multiplication:
[tex]\frac{4x}{5} = \frac{1}{10}[/tex]
[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]
