Determine the deegres of freedom.

t=2.037 (student's appendix)



We are 95% confident that average commuting time for rute A is between 0.3 and 2.3 min shorter than for rute B.
On average, people visit Thrillville 2 more times per year than Funland.
<h3><u>Averages</u></h3>
To determine how many more times per year, on average, do people visit Thrillville than Funland, the following calculation must be performed:
- Funland: 4,1,2,1,5,6,3,2,4,3,2,6,1,3,2 = 45
- 45 / 15 = 3
- Thrillville: 8,6,5,7,2,5,4,2,1,9,3,8,3,7,5,2,9,4,2,8 = 100
- 100 / 20 = 5
- 5 - 3 = 2
Therefore, on average, people visit Thrillville 2 more times per year than Funland.

Answer:
500 phones
Step-by-step explanation:
cost of manufacturing: y = 80x + 10,000
money from phone sales: y = 100x
* note: x = #phones
solve for when they're equal;
100x = 80x + 10,000
100x - 80x = 80x - 80x + 10,000
20x = 10,000 –––––––––––> divide both sides by 20
x = 500
Answer:
The cross section will be an isosceles triangle
Step-by-step explanation:
The picture of the question in the attached figure N 1
we know that
If a plane passes through the axis of rotation of the cone, then the resultant cross-section will be a triangle with one vertex as the vertex of the cone and the two sides of the triangle through the vertex A will be equal.
Where the base of the triangle will be equal to the diameter of the circular base of cone and the two congruent sides of triangle will be equal to the slant height of the cone
therefore
The cross section will be an isosceles triangle
Answer:
25
Step-by-step explanation:
Let n be the first integer.
Then the second integer will be (n + 1).
And the third will be (n + 2).
The sum is 78. Therefore:

Solve for n. Combine like terms:

So:

Therefore:

Therefore, the first integer is 25.
So our sequene is 25, 26, and 27.
The integer closest to zero will thus be 25.
