A professor grades a set of exams and then computes the quartiles:
Q0 = 60. Q1 = 70. Q2 = 80 Q3 = 87. Q4 = 95
If the professor curves every grade up by 10 points, then how will Q2 be affected by the curve?
I. It will increase by 10 points
ii. It will be 10 points higher than the median for the noncurved data
III It will be halfway between Q1 and Q3 for the curved data
a. I only
b. II and III
c. I, II and III
d. I and II
e. I and III
Answers
Answer:
Answer is c. I, II and II
Step-by-step explanation:
Solution:
Answer is c. I, II and II
It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.
Median for noncurved data = Q2 = 80
Median for curved data = 90
It will increase by 10 points = 90
It will be 10 points higher than the noncurved data = 90-80 = 10 points
if the set contains 20 values then, noncurved data will be:
60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95
Curved data will be: (all grades increased by 10 points)
70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105
Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97
Hence, C is the right answer

You want to put a fence around your large yard. There are two companies that you have found to do the work. They have each given you a quote for how much the work will cost. Of course, you want to find out which company will be the cheapest. The boundary of your yard is determined by five trees. The lines connecting them form the edge of your property. Shown below are the descriptions for the positions of the trees relative to your house.
TREE Position (relative to your house)
1 100 ft. east 2 40 ft east, 80 ft south 3 40 ft west, 120 ft south 4 90 ft west, 60 ft north 5 20 ft east, 110 ft north
STEP 1: On graph paper, mark the position of each of the trees on your land. Let each block of the graph paper represent a 10-foot by 10-foot square. Using a straightedge, connect Tree 1 to Tree 2, Tree 2 to Tree 3, Tree 3 to Tree 4, and so on.
STEP 2: Use the Pythagorean Theorem to find the length of each side of your property. Round
STEP 2
Length of segment 1 - 2 = √(8² + 6²) = 10 × 10 = 100 feet
Length of segment 2 - 3 = √(4² + 8²) = 4·√5× 10 = 40·√5 feet = 89.44 ft.
Length of segment 3 - 4 = √(5² + 18²) = √349 = 10·√349 feet = 186.82 ft.
Length of segment 4 - 5 = √(11² + 5²) = √146 = 10·√146 feet = 120.83 ft.
Length of segment 5 - 1 = √(11² + 8²) = √185 = 10·√185 feet = 136.01 ft.

From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]

Because both triangles are similar, we use the following equivalent ratios:

Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]

Answer: No, it is not commutative. If used a square as an example, centered at (1,1). If a dilation is performed on the square of a scale factor of 3, and the square is translated 5 units downward, then the result would be different than if I switched the order, doing the translation downward first and then performing the dilation centered at (1,1).

B) The model predicts that studying for 1.5 hours will result in an exam score of 60.
C) The model predicts that studying for 2.5 hours will result in an exam score of 70.
A scatter plot is a collection of points plotted on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the extent, if any, of correlation between the values of observed quantities or phenomena (called variables).
The scatter plot shows a positive relationship between study time and exam scores, with exam scores generally increasing as study time increases. However, the relationship is not linear and the increase in exam score is not always 10 points for each additional hour of study.
A) is not correct because the relationship between study time and exam score is not linear, and the increase in exam score is not always 10 points for each additional hour of study.
D) is not correct because the wording is unclear, it should be "The model predicts that studying for 4 hours will result in an exam score of (a specific number)".

Describe the possible lengths of the third side of the triangle given that the lengths of the other two sides are 12 feet and 18 feet.
I attached the picture too.
Answers
Answer:
6 ft < L₃ < 30 ft
Step-by-step explanation:
To obtain the answer to the question given above, we must bear in mind that:
The sum of the length of two sides of any triangle is always greater than the 3rd length i.e
L₁ + L₂ > L₃
With the above information in mind, we can obtain the answer to the question given above as follow:
Length 1 (L₁) = 12 feet
Length 2 (L₂) = 18 feet
Length 3 (L₃) =..?
Case 1:
L₁ + L₂ > L₃
12 + 18 > L₃
30 > L₃
L₃ < 30 feet
Case 2:
L₁ + L₃ > L₂
12 + L₃ > 18
Collect like terms
L₃ > 18 – 12
L₃ > 6 feet
Thus,
6 feet < L₃
Combining case 1 and 2,we obtained:
6 ft < L₃ < 30 ft
Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

3 more than a number is greater than 27
Answers
Answer:
n+3 > 27
Step-by-step explanation:
The inequality that represents the statement is x + 3 > 27 and the values of (x) which are greater than 24 are the possible solutions of this inequality.
What is inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It uses the following following operators to make comparison → >, <, ≤, ≥.
Given is the following mathematical verbal statement -
3 more than a number is greater than 27
We will first convert it into the inequality and then solve it. The inequality expression can be written by assuming a number. Let it be (x). So, we can write -
x + 3 > 27
Subtract 3 from both sides -
x + 3 - 3 > 27 - 3
x > 24
The inequality given above represents the statement and the values of (x) which are greater than 24 are the possible solutions of this inequality.
Therefore, the inequality that represents the statement is x + 3 > 27 and the values of (x) which are greater than 24 are the possible solutions of this inequality.

b. 40
d. 80
Please select the best answer from the choices provided
B
Look at image^^^
Answers
Answer:
d. 80
Step-by-step explanation:
Similarity ratio of ABCD to EFGH = 4:3.
This implies that the ratio of AD to EH = 4:3
If EH = 60, then:
AD:60 = 4:3
AD/60 = 4/3
Multiply both sides by 60
AD = ⁴/3 × 60
AD = 80
Mae Ling earns a weekly salary of $325 plus a 7.5% commission
on sales at a gift shop. How much would she make in a work week if she sold
$5,800 worth of merchandise? Write in money format.
Answers
Answer:
$760
Step-by-step explanation:
Given data
weekly = $325
commission= 7.5%
if she sold $5,800 worth of merchandise
Her earnings will be
Week earning= base salary+ 7.5% of sales
Week earning= 325+ 7.5/100*5800
Week earning= 325+ 0.075*5800
Week earning= 325+ 435
Week earning= $760

Answers
Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs
What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
