No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.) a + b > c
2.) a + c > b
3.) b + c > a.
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if all the two side lengths of a triangle is greater than the third side, then it makes a triangle.
is this correct? please help !!!!!

Which is an equation of a direct proportion?
A. =1/3−2
B. =3/
C. =−3+4
D. =−3
Answer:
D. y=-3x
Step-by-step explanation:
Direct Proportion
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is the constant of proportionality.
Solving for y:
y=kx
The only choice representing a direct proportion is:
D. y=-3x

value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.
Step-by-step explanation:
We are given:
[tex]a=b^2c^2d \:and\: d=\frac{1}{a}[/tex]
We need to find a in terms of b and c
We have: [tex]a=b^2c^2d[/tex]
Put value of d [tex]d=\frac{1}{a}[/tex]
[tex]a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc[/tex]
So, value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.

The composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)
What is the result of a composition between two functions?
The composition is a binary operator between two functions, in which the input of the first function is substituted by the second function. This operation is defined by the following expression:
(f ° g) (x) = f[g(x)]
If we know that f(x) = x and g(x) = 2, then the composition between the two functions is:
(f ° g) (x) = 2
Then, the composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)

A theater is showing 2 comedies, 1 musical, and 5 action films. Each movie has 3 matinee showtimes and 7 evening performances. Each type of movie and showtime is equally likely to be chosen. If 12,400 people see a movie, how many will be expected to choose a musical during an evening showtime? A 1,085 C 1,240 B 1,189 D 1,550
Answer: 1550
Step-by-step explanation:
Number of people to see the movie = 12400
Number of comedies = 2
Number of musical = 1
Number of action films = 5
The number of people that'll be be expected to choose a musical during an evening showtime will be:

4x – 4 = 2x + 2
Answer:
x =3
Step-by-step explanation:
4x – 4 = 2x + 2
Solving for x
Subtract 2x from each side
4x-2x – 4 = 2x-2x + 2
2x-4 = 2
Add 4 to each side
2x-4+4 = 2+4
2x = 6
Divide each side by 2
2x/2 = 6/2
x =3

Which of the following does NOT describe a parent function of a family of functions?
A. The parent function is the function with a graph that is different than all the other functions in the family.
B. The graphs of the functions in the family all have the same general shape as the parent function
C. The parent function is the simplest function that still satisfies the criteria to be in the family of functions
D. All of the functions in the family can be derived algebraically from the parent function by adding or subtracting terms or by multiplying by a constant
Answer:
A. The parent function is the function with a graph that is different than all the other functions in the family.
Step-by-step explanation:
A parent function is simply a function that represents the simplest form of a family of functions.
Now, a family of functions is defined as a group of functions that share the same highest degree and therefore the same shape for their graphs.
Looking at the options, the only one that doesn't correspond to the definition of parent function with respect to family of functions is option A because it suggests that the parent function is different from the family functions. Thus, option A doesn't describe a parent function.

The same shoes are available on double dribble’s web site for $57.75. A 9% processing fee will be applied to the cost of the shoes, plus a shipping fee of $5.99 for each pair.
What is the difference in the total costs of the 12 pairs of shoes between the two sites?
The difference in the total costs of the 12 pairs of shoes between the two sites is $46.77,
How to find the cost difference and total cost?Total cost is the sum up cost for all the individual process. we can find it by adding the cost for each steps.
In the given ques,
Super Sports is offering a 20% discount.
and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.
On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.
i.e. we have to find the difference in the total costs..
Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do times 1.065 by 696. And the answer to that is $741.24.
Do the same for other store. The answer to it is 788.01.
Thus, making Super Sports a better deal.
As, we need to find the difference. So, 788.01 - 741.24 = $46.77.

A trader bought aTV set for Birr 2000 and sold it at loss of 5 1/2%. what was the selling price?
Answer: birr 1780.
Solution:
The cost price of the T.V. set = birr 2000
The loss percentage = 5 1/2%
The formula of the selling price is: Selling Price = (100 - Loss%)/100 × Cost Price
Now,
By using the above formula and by substituting the given values of C.P. and Loss%, we get
Selling Price = (100 - 11)/100 × 2000
Selling Price = 89/100 × 2000
Selling Price = 89 × 20
Selling Price = 1780
Thus, the selling price of the T.V. set was → birr Given:
A trader bought a TV set for birr 2000 and sold it at a loss of 11%

Answer:
C.None of the above
Step-by-step explanation:
Let's consider the first answer choice:
The times in the semifinals were faster on average than the times in the finals.
We don't have to calculate the mean values of each distribution because we can see visually that the center of the final round distribution is lower than the center of the semifinal round distribution.
Since lower times are faster, we can't say that the times in the semifinals were faster on average than the times in the finals.
Now, let's consider the second answer choice:
The times in the finals vary noticeably less than the times in the semifinals.
We can see visually that the final round distribution is more spread out than the semifinal round distribution. We could calculate MAD or IQR from these displays, but we can see that the range of the final round distribution is larger.
So we can't conclude that the times in the finals vary noticeably less than the times in the semifinals.
you measure the period of a mass oscillating on a vertical spring ten times as follows: period (s): 1.06, 1.31, 1.28, 0.99, 1.48, 1.37, 0.98, 1.31, 1.59, 1.55 what are the mean and (sample) standard deviation?
The mean and (sample) standard deviation σ = 0.2098.
What exactly would the standard deviation indicate?The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
According to given information:The mean is the product of the dataset's total and the sample size. Mathematically.
[tex]\bar{x}=\frac{\sum X_i}{N}[/tex]
The individual periods are Xi.
The sample size is N.
[tex]\sum X i[/tex] = 1.06 + 1.31 + 1.28 + 0.99,+ 1.48 + 1.37+ 0.98 + 1.31 + 1.59 + 1.55
[tex]\sum X i[/tex] = 12.92
N = 10
While substituting the value we get:
x = 12.96/10
x = 1.292
The samples' average is 1.292.
The standard deviation:
[tex]\sigma=\sqrt{\frac{\sum(x-\bar{x})^2}{N}}[/tex]
[tex]\sum(x-\bar{x})^2[/tex] = (1.48-1.292)^2+(1.37-1.292)^2+(0.98-1.292)^2+(1.31-1.292)^2+(1.59-1.292)^2+(1.55-1.292)^2.
[tex]\sum(x-\bar{x})^2[/tex] = 0.43996
Putting into the formula we get:
[tex]\sigma=\sqrt{\frac{0.43996}{10}}[/tex]
σ = √(0.043996)
σ = 0.2098
The mean and (sample) standard deviation σ = 0.2098.
