Section 208 of nassau veterans Memorial Coliseum has 17 rows. The first row has 13 seats in it. If you add two seats to the previous row for each row in the section, how many seats are in row 15? How many seats total are there in the section?
Answers
We can write the explicit formula for an arithmetic sequence to represent this, since we add 2 each time:
13+2(n-1)
Using 15 for n,
13+2(15-1) = 13+2(14) = 13+28 = 41
To find the total number of seats, we evaluate the sum
[tex]\Sigma_{n=1}^{17} 13+2(n-1)[/tex]
Using technology to evaluate this sum, it is 493.

what is the difference between theoretical and experimental probability
Answers
Before I leave this part of the discussion, there is a computer simulation that mimics this game. It is called the Monte Carlo method. What you do is run a million draws from a computer deck of cards (1 to 52) and draw 1 card. If it is either the King of hearts or the king of diamonds you give yourself 1 point and record that a draw has taken place. If not you just record that a draw has taken place.
I just ran this simulation and out of a million draws, 38575/1000000 came back as successful. 1/26 = 0.03846 which means that the rounded version was accurate to 3 decimal places. But it was not the same as the theoretical draw.
A real world or experimental probability is like the Monte Carlo method. A survey is another real world or experimental probability. Who would have predicted the results of the last American election? Who would have thought that though Hillary got the popular vote, she was not elected?
Theoretical: what you calculate.
Experimental: what you get from a sample for example or a survey. Think elections or insurance policies.

how to tell if an ordered pair is a solution to a function
Answers
B) yes
C) no
For each of these, substitute the value of x in the ordered pair into x in the function.
For A, x = -5; -5<2, so the piece of the function we want is f(x) = 3. In our ordered pair, y=f(x)=3, so yes, it is a solution.
For B, x = 2; 2≤2<6, so the piece of the function we want is f(x) = -x+1. In our ordered pair, y=f(x)=-1; -2+1=-1, so yes, it is a solution.
For C, x = 8; 8≥6, so the piece of the function we want is f(x) = x. In our ordered pair, y=f(x)=-7; -7≠8, so no, it is not a solution.

What do you do about the arc? It is 211o - 1? That value = the central angle. A central angle is the angle going from K to the center of the circle to M. 1/2 that amount is the angle going to anywhere on the arc of the circle. So that is 1/2 of 211 - 1 = 105.5x - 1/2
These two angles when added together = 180o
105.5x - 1/2 + 104x + 1 = 180o Collect like terms on the left
209.5x + 1/2 = 180 Subtract 1/2 from both sides
209.5x = 180 - 1/2
209.5x = 179.5 Divide by 209.5
x = 179.5 / 209.5

Two points move along a circle of length 120m with a constant speed. If they move in different directions, then they meet every 15 seconds. When going in the same direction, one point catches up to the second every 60 seconds. Find the speeds of the points.
Answers
Let x and y be the speeds of the two points. The circle is of length 120m that is Circumference of circle is 120m.When the points are moving in opposite directions, they meet in every 15 seconds.That is the points cover 120m in 15 seconds.As they are moving in opposite directions, so the relative speed will be equal to the sum of speeds of both points.Speed= Distance ÷Time = 120÷15=8m per seconds.
x+y=8
When going in the same direction, one point catches up to the second every 60 seconds.Speed= 120÷60=2 m per seconds
x-y=2.
Solving the two equations by elimination method:
x+y=8.
x-y=2
Adding the equations:
2x=10 ,x=5m / sec.
x+y=8
5+y=8
y=3m/sec.
Thus, the speed of the two points is 5 m/s and 3 m/s.

________________________________________________________
Explanation:

The formula for the volume, "V" , of a cylinder is:
→ V = [tex] \pi [/tex] * r² * h ;
→ in which "r = length of radius" ; "h = height" ; ________________________________________________________
{Note that the formula for the volume, "V" , of a cylinder is:
→ " Base area * height " .
________________________________________________________
→ Specifically, for a cylinder, the "Base area" is the area of a "circle", because the base is a circle;
→ and the formula for the "area of a circle = [tex] \pi [/tex] * r² " ;
→ in which "r = length of the radius" .
As such, the formula for the volume, "V" , of a cylinder is:
______________________________________________________
→ Volume = (Base area) * (height) ;
= ( [tex] \pi [/tex] r² ) * h ;
______________________________________________________
→ V = [tex] \pi [/tex] r² h ;
in which: "V = volume {in "cubic units" ; or, write as " units³ " } ;
"r = radius length" ;
"h = height" ;
_____________________________________________________
→ Now, we shall solve for the volume, "V", of the given cylinder in this question/problem:
_____________________________________________________
→ V = [tex] \pi [/tex] r² h ;
in which: "r = radius = ? " ;
→ To find "r" ; We are given the diameter, "d = 40 mm" ;
→ Note that: "r = d/2 = (40 mm) / 2 = 20 mm " ;
{i.e., "the radius is half of the diameter".}.
→ " r = 20 mm " ;
→ " h = height = 30 mm " {given in figure) ;
→ For [tex] \pi [/tex] ; let us use " 3.14 " — which is a commonly used approximation.
→ For this question/problem, none of the answer choices are given "in terms of [tex] \pi [/tex] " ;
→ so we shall use this "numerical value" as an "approximation" ;
_______________________________________________________
Now, let us plug in our known values into the formula;
and calculate to find the volume, "V", of our given cylinder; as follows:
_______________________________________________________
→ V = [tex] \pi [/tex] r² h ;
= (3.14) * (20 mm)² * (30 mm) ;
= (3.14) * (20)² * (mm)² * (30 mm) ;
= (3.14) * (20)² * (30) * (mm³) ;
= (3.14) * (400) * (30) * (mm³) ;
= 37, 680 mm³

$119.66
in interest over the course of a year if he transfers his balance to a credit
card with an APR of 19.1%, compounded monthly. The correct answer between all
the choices given is the first choice or letter A.
Answer:
Barney will save about $119.66.
Step-by-step explanation:
The compound interest formula is:
A=[tex]p(1+\frac{r}{n})^{nt}[/tex]
Case 1:
when p = 780
r = 0.313
n = 12
t = 1
Putting the values in formula:
[tex]780(1+\frac{0.313}{12})^{12}[/tex]
A = [tex]1.36204\times780=1062.39[/tex]dollars
Interest accured = [tex]1062.39-780=282.39[/tex] dollars
Case 2:
when p = 780
r = 0.191
n = 12
t = 1
Putting the values in formula:
[tex]780(1+\frac{0.191}{12})^{12}[/tex]
A = [tex]1.20863\times780=942.73[/tex]dollars
Interest accured = [tex]942.73-780=162.73[/tex] dollars
Now difference in interest in both cases = [tex]282.39-162.73=119.66[/tex] dollars
Hence, Barney will save about $119.66.

Which fraction is multiple of 1/10
Answers
Final answer:
A multiple of 1/10 is any fraction obtained by multiplying 1/10 by an integer. For example, 1/10 multiplied by 2 is 2/10, which simplifies to 1/5. Dividing by powers of 10 shifts the decimal point left, making 1.9436 divided by 1,000 equal to 0.0019436.
Explanation:
In mathematics, when identifying a multiple of a fraction, you look for fractions that can be created by multiplying the original fraction by an integer. In the case of 1/10, a multiple would be any fraction where 1/10 is multiplied by a whole number.
For instance:
1/10 multiplied by 2 is 2/10, which simplifies to 1/5 - thus 1/5 is a multiple of 1/10.1/10 multiplied by 3 is 3/10 - hence, 3/10 is a multiple of 1/10.Multiplying 1.9436 by powers of 10 shifts the decimal point accordingly:
1.9436 × 10 = 19.4361.9436 × 100 = 194.361.9436 × 1,000 = 1,943.6Conversely, dividing by powers of 10 will shift the decimal point to the left, making the number smaller:
1.9436 ÷ 10 = 0.194361.9436 ÷ 100 = 0.0194361.9436 ÷ 1,000 = 0.0019436The fraction 15 can be simplified by dividing both the numerator and the denominator by the greatest common factor, in this case, 15, yielding a value of 1.

A one-tablespoon serving of olive oil contains 120 calories. The label on a bottle of olive oil states that it contains 66 servings. How many calories are in the whole bottle of olive oil?
Answers
The whole bottle of olive oil contains 7920 calories.
To find the total number of calories in the entire bottle of olive oil, one must multiply the number of calories in one serving by the total number of servings in the bottle.
Given that one tablespoon serving of olive oil contains 120 calories, and the bottle contains 66 servings, the calculation is as follows:
Total calories in the bottle = Calories per serving [tex]\times[/tex] Number of servings
Total calories in the bottle = 120 calories/serving [tex]\times[/tex] 66 servings
Total calories in the bottle = 7920 calories
Therefore, the whole bottle of olive oil contains 7920 calories.
