Find the probability that a randomly selected point within the circle falls in the red shaded area (square). Round to the nearest tenth of a percent.
Answers
Answer:
probability of selecting the square is 63.7% approximately
Step-by-step explanation:
First of all, the probability of the point of choice is within the red square can be obtained with this formula
probability = expected outcome / total number of possible outcomes
In this case, we are not dealing with discrete values which can be counted. instead, we are dealing with areas.
We are to go about this problem by finding the area of the internal square and dividing it by the area of the circle.
Area of the square
Area of the square = [tex]l^2[/tex]
where length = [tex]4\sqrt{2}[/tex]
Area = [tex](4\sqrt{2}) ^2 = 32cm^2[/tex]
Area of the circle
Area of the circle = [tex]\pi r^2[/tex]
area of circle =[tex]\pi \times 4^2 =50.26cm^2[/tex]
Probablity of selecting the square =
32/50.26 = 0.6366
To express this as a percentage, we multiply our answer by 100.
This will give us 0.6366 X 100 = 63.7% approximately

Answers
Answer:
96 in.²
Step-by-step explanation:
Surface Area of the prism = 2(area of the 2 equal triangles) + area of rectangle A + rectangle B + rectangle C
✔️Area of the two triangles with the following dimensions:
height = 3 in.
base = 4 in.
Area = 2(½*4*3) = 12 in.²
✔️Area of rectangle A = L*W
L = 7 in
W = 5 in
Area of rectangle A = 7*5 = 35 in.²
✔️Area of rectangle B = L*W
L = 7 in
W = 4 in
Area of rectangle B = 7*4 = 28 in.²
✔️Area of rectangle C = L*W
L = 7 in
W = 3 in
Area of rectangle C = 7*3 = 21 in.²
✔️surface area of the prism = 12 + 35 + 28 + 21 = 96 in.²

Answer:
8x^2 - 26x - 10
Step-by-step explanation:
3(6x2 + 3x - 5 ) = 18x^2 + 9 -15
5(2x2 + 7x - 1) = 10x^2 + 35 - 5

Answer:
Both are TRUE
Step-by-step explanation:
✔️The statement, "angles 1 and 5 are corresponding angles" is TRUE.
Rationale/reason:
Angles that have corners that match are called corresponding angles. Angles 1 and 5 are angles found in the corners that match each other. Therefore, they are corresponding.
✔️The statement, "Angle 6 is congruent to angle 4" is TRUE.
Rationale/reason:
When two lines that are parallel is crossed by a transversal, the alternate interior angles formed are congruent to each other.
Angles 4 and 6 are interior angles that alternate each other along the transversal. Therefore they are congruent to each other.

in an office building,92 offices are currently being rented. This represents 80% of the total units. How many offices are in the building?
Answers
Answer:
Number of offices in the building = 115
Step-by-step explanation:
Let x be the total number of offices.
Then 80% x= 92 or 80/100 * x =92
Hence, x = 92*100/80 = 9200/80= 115
Solve for the missing side lengths indicated by the question mark.
Answers
Answer:
6; 40
Step-by-step explanation:
Problem 1:
Based on the triangle similarity theorem, we would have the following equation:
Let the missing side length = x
Thus:
(15 + x)/15 = 14/(14 - 4)
(15 + x)/15 = 14/10
(15 + x)/15 = 7/5
Cross multiply
5(15 + x) = 7*15
75 + 5x = 105
5x = 105 - 75
5x = 30
x = 30/5
x = 6
Missing side = 6
Problem 2:
Applying similarly theorem also, we have:
Let the missing side = x
x/(x - 25) = 24/(24 - 15)
X/(x - 25) = 24/9
x/(x - 25) = 8/3
Cross multiply
x*3 = 8(x - 25)
3x = 8x - 200
3x - 8x = -200
-5x = -200
x = -200/-5
x = 40
Missing side = 40

So for 7 days it costs $90 720
First we need to find what 1 day cost
So you will divide $90 720 by 7
90 720÷7= $12 960
To find the cost for 3 days your gonna multiply $12 960 by 3
12 960×3= $38 880

Answer:
they are alternate interior angles to parallel lines.
Step-by-step explanation:
The reason for this is that they are alternate interior angles to parallel lines. The straight dotted lines that represent the line of sight of each individual are parallel to each other while the elevation line in this scenario would be considered the Transversal as it passes through both of them. This ultimately causes the angles between the transversal and the line of sight to be alternate interior angles which are equal to one another, as can be seen in the attached demonstration in the image below.
Choose all values of the correlation coefficient, r, that indicate a strong, but not perfect, linear association between two variables.
A r=-0.85
B. r=-0.10
C. r= 0.15
D. r=0.90
E r= 1.00
Answers
Answer:
D. r = 90
A. r = -0.85
Explaination:
• r = 1 is perfect and strong.
• So r = 90 is strong but not perfect.
• Same with -0.85, but as negative.
-0.85, and 0.90 indicate a strong relationship between the two variables but not a perfect linear association between the two variables option (A) and (D) are correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have a value of correlation coefficients.
We know when the correlation coefficient r is 1 then we can say the relation between two variables is perfect and strong.
When the value of correlation coefficients lies between 0.8 to 1 the relation between two variables is said to be strong.
Similarly when the value of correlation coefficients lies between -0.8 to -1 the relation between two variables is said to be strong.
For the r = -0.85, this indicates a strong relationship but is not perfect.
For the r = -0.10 this indicates a weak relationship but is not perfect.
For the r = 0.15 this indicates a weak relationship but is not perfect.
For the r = 0.90 this indicates a strong relationship but is not perfect.
For the r = 1 this indicates a strong relationship and perfect.
Thus, -0.85, and 0.90 indicate a strong relationship between the two variables but not a perfect linear association between the two variables option (A) and (D) are correct.

Construye una fórmula que permita calcular el dinero recaudado en un autobús en función de los billetes vendidos, sabiendo que cada uno cuesta 1,2 euros. Represéntala. ¿Se pueden unir los puntos?
Answers
Answer:
1.2X = $
Step-by-step explanation:
Para construir una fórmula que permita calcular el dinero recaudado en un autobús en función de los billetes vendidos, sabiendo que cada uno cuesta 1,2 euros, se debe realizar el siguiente razonamiento lógico matemático:
1.2(variable fija) x X (número de billetes vendidos) = $ (Dinero recaudado)
1.2X = $
Por lo tanto, si por ejemplo se hubiesen vendido 100 billetes, la ecuación operaría de la siguiente manera:
1.2 x 100 = $
120 = $

Candy and Hershel folded the same-size square papers.
Candy shaded 2/4 and Hershel shaded 1/2 . Are the fractions equivalent?
Answers
Answer:
The fractions are equivalent.
Step-by-step explanation:
2/4 can be simplifyed as 1/2 meaning they are equivalent.
Candy shaded 2/4 and Hershel shaded 1/2 represent the same amount of shaded area on their respective square papers.
To determine whether the fractions 2/4 and 1/2 are equivalent, we can simplify both fractions and compare them.
First, let's simplify the fraction 2/4:
The numerator and denominator of 2/4 have a common factor of 2. By dividing both the numerator and denominator by 2, we get:
2/4 ÷ 2/2 = 1/2
Now, let's compare the simplified fraction 1/2 to the fraction 1/2 that Hershel shaded.
Since both fractions are now 1/2, we can conclude that the fractions are indeed equivalent. Therefore, Candy shaded 2/4 and Hershel shaded 1/2 represent the same amount of shaded area on their respective square papers.
