Topic: Similar Triangles
Determine whether the triangles are similar by AA ~, SSS ~, SAS~, or not similar. If the triangles are similar, write a valid similarity statement.
Answers
Answer:
The triangles are not similar
Step-by-step explanation:
The ratios of the 2 triangles are not equivalent to each other so the triangles are not proportional. Since the triangles are not proportional, the triangles are not similar.
16/26= 8/13
21/32= 21/32
Plus, you can't determine if the triangles are similar by SAS and SSS since the problem doesn't give you enough information.

A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32% buy something and decide to test the claim. You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase. The value of the test statistic is about:
A. 1.74
B. 1.60
C. 1.48
D. -1.60
E. -1.48
Answers
Answer:
E. -1.48
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase.
This means that:
[tex]\mu = 0.32[/tex]
[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]
You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.
This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]
The value of the test statistic is about:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]
[tex]t = -1.48[/tex]
So the correct answer is given by option E.
HURRY PLZ HELP 60% oF MY GRADE!! 9. You are selling tickets for a high school concert. Student tickets cost $4 and
general admission tickets cost $6. You sell 450 tickets and collect $2340. How
many of each type of ticket did you sell?
Answers
Answer:
hjeoo
Step-by-step explanation:
x + y = 450 --> y = 450 - x
4x + 6(450 - x) = 2340
4x + 2700 - 6x = 2340
-2x = -360
x = 180 --> there were 180 $4 tickets sold.
and
450 - 180 = 270 $6 tickets

The total area of three walls, each 8' feet high; 14, long, and other is 10' long?
Answers
Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²

Intro
Done
Answers
Answer:
x = -2; or x = -8
Step-by-step explanation:
Solve the quadratic function by completing the square. What are the missing pieces in the steps? -32=2(x^2+10)
-32+___=2(x2+10x+25)
18=2(x+5)^2
9=(x+5)^2
+-___=x+5
X=-2 or x=___
Solution:
From the first line:
-32+___=2(x2+10x+25)
Also, in the second line:
18=2(x+5)^2
Let the missing piece on line 2 be a, hence:
x² + 10x + 25 = (x + 5)² and -32 + a = 18
a = 18 + 32 = 50
-32 + 50 =2(x²+10x+25)
18 = 2(x+5)²
Dividing through by 2:
18 / 2= [2(x+5)² / 2]
9 = (x + 5)²
Taking square root of both sides:
√9 = √(x + 5)²
± 3 = x+5
Simplifying the equation to get:
3 = x + 5; -3 = x + 5
x = 3 - 5; or x = -3 - 5
x = -2; or x = -8

the mean of 16,18,x,12 and 15 calculate the value of x
Answers
Answer:
29
Step-by-step explanation:
Mean = sum of datas/Sample size
Given the data 16,18,x,12 and 15
Sum = 16+18+x+12
Sum = 46+x
Mean = 15
Sample size = 5
Substitute
15 = 46+x/5
15 * 5 = 46+x
75 = 46 + x
x = 75-46
x = 29
Hence the value of x is 29

A line that passes through (-1, 6) and the origin
Answers
Answer: The equation is y = -6*x
Step-by-step explanation:
I suppose that we want to find the equation for a line that passes through the point (-1, 6) and the origin (remember that the origin is the point (0,0))
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If this line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of the line is equal to:
a = (y₂ - y₁)/(x₂ - x₁)
Now we know that our line passes through the points (0, 0) and (-1, 6), then the slope is:
a = (6 - 0)/(-1 - 0) = 6/-1 = -6
Then our equation is something like:
y = -6*x + b
To find the value of b we can use the fact that this line passes through the point (0, 0).
This means that when x = 0, y is also equal to zero.
If we replace these values in the equation we get:
0 = -6*0 + b
0 = b
Then our equation is:
y = -6*x

A. 10(a) A shoe company is going to close one of its two stores and combine all the inventory from both stores. These polynomials represent
the inventory in each store:
Store A:1/2g^2+7/2
Store B: 3g^2-4/5g+1/4
Which expression represents the combined inventory of the two stores?
Answers
Answer: answer should be A , 7/2g2-4/5g+15/4
Step-by-step explanation:
The combined inventory of the store is 7 / 2 g² - 4 / 5 g + 15 / 4
Combining polynomial
Combining polynomial simply means to add the polynomials. Therefore,
Store A = 1 / 2 g² + 7 / 2
Store B = 3 g² - 4 / 5 g + 1 / 4
The combine inventory of the store is as follows;
Combine inventory = 1 / 2 g² + 7 / 2 + 3 g² - 4 / 5 g + 1 / 4
Combine like terms
Combine inventory = 1 / 2 g² + 3 g² - 4 / 5 g + 7 / 2 + 1 / 4
Combine inventory = 7 / 2 g² - 4 / 5 g + 15 / 4
Combine inventory = 7 / 2 g² - 4 / 5 g + 15 / 4
