Use the table below to determine whether the argument is valid. TableI start to fall asleep if I read a math book. I drink soda whenever I start to fall asleep. If I drink a soda, then I must eat a candy bar. Therefore, if I read a math book, then I eat a candy bar.The argument is _____________
Answers
Okay, here we have this:
Considering the provided information, we obtain the following:
I read a math book. (p)
I start to fall asleep (q)
I drink soda (r)
I must eat a candy bar. (s)
Therefore:
I start to fall asleep if I read a math book. This can be rewritten as: "if I read a math book then I start to fall asleep". And this is p⇒q.
I drink soda whenever I start to fall asleep. This can be rewritten as:"if I start to fall asleep then I drink soda" . And this is q⇒r.
If I drink a soda, then I must eat a candy bar. And this is r⇒s
Now, we need to check: "If I read a math book, then I eat a candy bar.". That is p⇒s.
So, according with the table this argument satisfy the Transitive Reasoning, so this means that the argument is valid.

The common difference of the sequence is d, and the number a is the first term. [tex]a_{n}[/tex] = a + (n - 1)d is the formula for an arithmetic sequence's nth term.
The common difference, or d, is the difference between any two consecutive terms in an arithmetic sequence, and it may be calculated by deducting any pair of terms beginning with a and ending with [tex]a_{n+1}[/tex] Accordingly, d = [tex]a_{n+1}[/tex] - [tex]a_{n}[/tex]
It is given that height of each stair is 18 cm
Height of first stair = 18 cm
Height of second stair = 18 + 18 = 36 cm
Height of third stair = 36 + 18 = 54 cm
and so on.
This data will make a sequence such as 18 , 36 , 54 , 72 ..........

Common difference , d = 36 - 18 = 18
For the height of nth stair , use the formula of [tex]a_{n}[/tex]

Circle M dilated by a scale factor of 3 gives circle N. If the circumference of circle N is 6 cm, what is the circumference of circle M?
Answers
For this problem, we are given two circles, M and N, that are related by a scale factor of 3, we know that the circumference of the larger circle is 6 cm, and we need to determine the circumference of the smaller one.
The circumference of a circle can be found by using the following expression:
[tex]C=2\pi r[/tex]Where 'r' is the radius. When the circles are scaled, their radii should be scaled at the same proportion, so the following demonstrates the relation between both radii:
[tex]r_n=3\cdot r_m[/tex]We know that the circumference for the circle N is equal to 6 cm, therefore we have:
[tex]6=2\pi\cdot r_n[/tex]If we replace the radius for circle n, with the second expression, we will obtain:

Determine the value of altitude BD to the nearest tenth.
Answers
1) Given the altitude BD, let's find its measure using some trigonometric relations on the Right Triangle:
1.2) Pythagorean Theorem to find the other leg
b²=a²+c² The hypotenuse, in this case, is labeled as "b"
32²=16²+a²
1024=256+a²
1024-256=a²
768=a²
√768=√c²
a=16√3
2) Now, let's use one trigonometric relation on the Right Triangle, based on the similarity of the triangles:
ah=bc Adjusting it:
bh=ac
32h=16√3*16
32h=256√3
h=256√3/32
h=8√3 ≈ 13.85 ≈13.9
3) So the altitude BC of that triangle is approximately 13.9
2.Which data set is more likely to produce a histogram with a symmetric distribution? Explain yourreasoning.Data on the number of seconds on a track of music in a pop album.Data on the number of seconds spent talking on the phone yesterday by everyone in theschool.
Answers
A histogram with a symmetric distribution looks like this:
Leaving aside the quality of the drawing, the left and the right side of the histogram are identical if we split it by the red line. Is like having a reflexion axis.
Now, we have to discuss what of the 2 data sets may have such an histogram. This means that we must think which of them may have the same number of ocurrences for very short and very long durations, for regular to short and regular to long durations, and so on and so furth.
Pop album tracks:
In the same album we may have arround 12 tracks (small number), all of them with a duration of arround 3 minutes. We could imagine a histogram like the following:
All the songs last between 170 and 190 seconds, and one or two last a little bit more.
Phone talks:
In this case, we can think that there are some calls to say something like "mom, I'm on my way home" and other like "let me tell you the hole movie I saw yesterday night", so very short and very long calls, but they are no so common. There are a lot of "regular" calls that might last for 60 seconds.
Also, in this case, we are taking into account all the calls from people in the school in one day (yesterday), so, may be 1.000 calls? The actual number really doesn't matter, but the fact that the number is very big. Because of the big number, we can expect a symmetric distribution.

If the total price for two cars at the dealership is $87,000, where one car’s price is $6000 less than twice the other, what is the price of the cheaper vehicle?
Answers
The price of the cheaper vehicle, given the total price of the two cars can be found to be $40, 500
How to find the price?Assuming the price of the cheaper car is denoted as x, the formula for the price of the more expensive car would be:
= Price of cheaper car + $6, 000
= 6, 000 + x
Finding the value of the cheaper car in the dealership can be found by the formula:
x + (6, 000 + x) = 87, 000
2x + 6, 000 = 87, 000
2x = 87, 000 - 6, 000
x = 81, 000 / 2

What is the difference between exponential growth and exponential decay?An exponential function has the generic formula y = abx, where a = 0 and b = a positive real number. When describing an exponential function, the base b is a constant.

Answers
Solving the equations for the total number of adults and children and respective ticket costs, we find out that the number of adults and children that attended the movie theater are 13 adults and 6 children.
It is given to us that -
A total of 19 people attended the movie theater which was a mix of adults and children
Each adult ticket was $9
Each child’s ticket was $5.50.
Total cost for the party was $150
We have to find out the number of adults and children that attended the movie theater.
Let us assume that the number of adults and children that attended the movie theater be [tex]x[/tex] and [tex]y[/tex] respectively.
Since, a total of 19 people attended the movie theater including both adults and children, we can say that -
[tex]x+y=19[/tex] ------ (1)
It is also given that each adult ticket was $9 and each child’s ticket was $5.50. So,
For [tex]x[/tex] adults, the ticket price = [tex]9x[/tex], and
For [tex]y[/tex] children, the ticket price = [tex]5.5y[/tex]
It is given that the total cost for the party was $150
[tex]= > 9x+5.5y=150[/tex] ------- (2)
From equation (1), we have
[tex]x+y=19\\= > y =19-x[/tex] ------ (3)
Substituting this value of [tex]y[/tex] in equation (2),
[tex]= > 9x+5.5y=150\\= > 9x+5.5(19-x)=150\\= > 9x +104.5-5.5x=150\\= > 3.5x=45.5\\= > x=13[/tex]------ (4)
Substituting this value of [tex]x[/tex] from equation (4) in equation (3), we get
[tex]y=19-x\\= > y=19-13\\= > y=6[/tex]

The length of the rectangle is 40
yards less than twice the width.
What are the dimensions of the
park?
Answers
The dimensions of the rectangular park are 200 yards by 120 yards.
We have a park. The shape of the park is a rectangle. The perimeter of the rectangular park is 640 yards. We know that the length of the rectangle is 40 yards, less than twice its width. We need to find the dimensions of the rectangular park.
Let the perimeter, length, and width of the rectangle be represented by the variables "P", "l", and "b", respectively. The perimeter of the rectangle is twice the sum of its length and width.
l = 2b - 40
P = 2*(l + b)
640 = 2(2b - 40 + b)
320 = 3b - 40
3b = 360
b = 120
Hence, the width of the rectangular park is 120 yards. We will substitute this value in the above equation to find the length.
l = 2b - 40
l = 2(120) - 40
l = 240 - 40
l = 200
Hence, the length of the rectangular park is 200 yards.
