Answer: A. 51.9, 52, 49, 6
Step-by-step explanation:
The given data : 49, 49, 54, 55, 52, 49, 55
[tex]{\text{Mean =}\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
[tex]{\text{Mean =}\dfrac{363}{7}=51.8571428571\approx51.9[/tex]
For Median , first we arrange observations in order.
49, 49, 49, 52, 54, 55, 55
Median = Middlemost observation = 52
Mode = Most repeated observation = 49
Range = Maximum number -Minimum number
[tex]=55-49=6[/tex]

The shelf is made of 3 pieces of wood, each 0.3 meter wide. There is also 0.05 meter of space between the shelf and the wall on each side. What is the width, in meters, of the closet?
A. 0.4
B. 0.8
C. 1
D. 1.9
The correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.
To determine the width of the closet, we need to add up the widths of the three pieces of wood and the spaces on each side.
Given:
- Width of each piece of wood: 0.3 meters
- Number of pieces of wood: 3
- Space on each side between the shelf and the wall: 0.05 meters
Now, calculate the total width:
[tex]\[ \text{Total Width} = (\text{Width of one piece of wood} \times \text{Number of pieces of wood}) + (\text{Space on one side} \times 2) \][/tex]
[tex]\[ \text{Total Width} = (0.3 \times 3) + (0.05 \times 2) \][/tex]
[tex]\[ \text{Total Width} = 0.9 + 0.1 \][/tex]
[tex]\[ \text{Total Width} = 1 \, \text{meter} \][/tex]
The width of the closet is 1 meter, considering the combined width of the three pieces of wood and the spaces on each side.
Therefore, the correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.

Which of the following ordered pairs lies on the graph of h(x) = -2x^2?
(1, -4)
(1, -2)
(1, 4)
Answer: The correct option is second,i.e., (1,-2).
Explanation:
The given equation is,
[tex]h(x)=-2x^2[/tex]
We have to find which of the ordered pair lies on the graph of h(x). A
In all ordered pairs the values of x coordinate are same that is 1 and the values of y coordinate are different.
Put x = 1 in the given function.
[tex]h(1)=-2(1)^2[/tex]
[tex]h(1)=-2(1)[/tex]
[tex]h(1)=-2[/tex]
The value of function is -2 at x = 1, so the ordered pair (1,-2) lies on the graph of the function h(x).
Therefore, the second option is correct.

Dale has a special deck of cards. Each card has a different rational number on it. The cards are 0.25,4/5,2/9,0.48, and 8/11. How many cards have a value that is greater than 1/2
Answer:
Below:
Step-by-step explanation:
There are two cards which have a value greater than 1/2. In order to calculate this, you need to look at the numbers. 0.25 equals 1/4, which is not greater than a half. 2/9 would also not be greater than one half. 1/2 is .50, so .48 would also not be greater.

The histogram shows the scores of students on their most recent history test. How many students scored 80% or better on the test?
The number of students who scored 80% or better can be partially determined from the histogram data, with five students explicitly scored between 90 and 99%. The exact number scoring between 80 and 89% isn't provided, but those students would also be included in the count.
Explanation:To determine how many students scored 80% or better on their most recent history test, we need to focus on the histogram's data for the ranges of 80 to less than 90 and 90 to less than 100. According to the information provided, five students scored between 90 and 99% (A range). However, the exact number of students who scored between 80 and 89% is not directly stated. Nevertheless, the data suggest that most students scored within the 70-89% range, with some scoring in the 60-69% range and a few in the 90-100% range.
Given that five students received an A (90-99%), and assuming the distribution includes students scoring between 80-89%, we would also count those students. Without the specific number for the 80-89% range, it's crucial to analyze the provided data to estimate or directly state numbers within this context. Thus, our primary focus for students who scored 80% or better combines those explicitly mentioned five students with an undefined number scoring within the 80-89% range.

Which postulate or theorem proves that these two triangles are congruent?
AAS Congruence Theorem
SAS Congruence Postulate
ASA Congruence Postulate
HL Congruence Theorem
From the figure,
JHGF is a parallelogram.
From the properties of parallelogram,
∠ F = ∠ H (opposite angles are equal)
FG = JH (opposite sides are equal)
Also, note that FG || JH and JG is a transversal.
Therefore,
∠ FGJ = ∠ GJH (Alternate interior angles are equal)
Now, in Δ FGJ and Δ GJH,
FG = JH
∠ F = ∠ H and
∠ FGJ = ∠ GJH
Hence, the triangles are congruent by AAS Congruence Theorem.
The triangles [tex]\triangle \text{FJG}[/tex] and [tex]\triangle \text{JHG}[/tex] are congruent by [tex]\fbox{\begin\\\ \bf {AAS congruence theorem}\\\end{minispace}}[/tex].
Further explanation:
From the given figure it is observed that there are two triangles [tex]\triangle \text{FJG}[/tex] and [tex]\triangle \text{JHG}[/tex] inside the quadrilateral.
Two triangles are said to be congruent if both the triangles have same angles and sides or it can be said that two triangles are congruent if they completely overlap with each other.
The theorems to check the congruency for the two triangles are as follows:
1) SSS congruence theorem:
As per the SSS congruence theorem if all the three sides of the first triangle are equal to all the three sides of the second triangle then the two triangles are called congruent triangles.
2) SAS congruence theorem:
As per the SAS congruence theorem if the two sides of first triangle are equal to the two sides of the second triangle and the including angles are equal then the two triangles are called congruent triangles.
3) AAS congruence rule:
As per the AAS congruence theorem if the two angles of first triangle are equal to the two angles of the second triangle and the similarly located sides are equal then the two triangles are called congruent triangles.
4) HL congruence rule:
As per the HL congruence theorem if the hypotenuse and the one other side of a triangle is equal to the hypotenuse and the corresponding other side of the second triangle then the two triangles are called congruent triangles.
From the given figure it is observed that [tex]\angle \text{GJH}[/tex] is equal to the [tex]\angle \text{JGF}[/tex], [tex]\angle \text{GHJ}[/tex] is equal to the [tex]\angle \text{GFJ}[/tex] and the side JG is the common side for [tex]\triangle \text{FJG}[/tex] and [tex]\triangle \text{JHG}[/tex].
From figure 1 (attached in the end) it is observed that the [tex]\angle \text{GJH}[/tex] and the [tex]\angle \text{JGF}[/tex] lies on same side, [tex]\angle \text{GHJ}[/tex] and the [tex]\angle \text{GFJ}[/tex] lies on the same side and the side JG is common for the [tex]\triangle \text{FJG}[/tex] and [tex]\triangle \text{JHG}[/tex].
For triangles [tex]\triangle \text{FJG}[/tex] and [tex]\triangle \text{JHG}[/tex].
[tex]\fbox{\begin\\\ \begin{aligned}\angle\text{GJH}&=\angle\text{JGF}\\ \angle\text{GHJ}&=\angle\text{GFJ}\\ \text{JG}&=\text{JG}\end{aligned}\\\end{minispace}}[/tex]
So, as per the concept of AAS congruence theorem the two triangles [tex]\triangle\text{FJG}[/tex] and [tex]\triangle\text{JHG}[/tex] are the congruent triangles.
Therefore, the theorem according to which the triangles [tex]\triangle\text{FJG}[/tex] and [tex]\triangle\text{JHG}[/tex] are congruent is [tex]\fbox{\begin\\\ \bf {AAS congruence theorem}\\\end{minispace}}[/tex].
