No, the frequencies do not decrease from the maximum frequency to a low frequency
Answer:
Yes, all the requirements are met.
Step-by-step explanation:
Frequency Distribution is a graph or table which shows the frequency of different outcome.
Normal Distribution has bell like-shape.
Since here the value of frequency is less for score 50-69 then it increases from 70- 109 then the frequency is again decreasing from score 110-149. So the curve of frequency distribution when plotted appears like bell-shaped. Hence, It appears like a normal distribution.

What is the length of the diagonal of the square shown below?
Answer:
sqrt(50)
Step-by-step explanation:
Since it is a right triangle, we can apply the Pythagorem Theorem.
a^2 + b^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt(50)
The length of the diagonal of the square is 5 [tex]\sqrt{2[/tex]
The length of the diagonal of a square is equal to the square root of 2 times the length of a side. In this case, the side length is 5, so the diagonal of the square is 5√2
Let's break down the steps to find the square root of 50:
1. **Given**: We have a right triangle with side lengths:
[tex]- \(a = 25\)\\ - \(b = 25\)2. Apply the Pythagorean Theorem: \[a^2 + b^2 = c^2\] \[25^2 + 25^2 = c^2\] \[50 = c^2\]3. Solve for \(c\): \[c = \sqrt{50}\]4. Calculate the square root of 50: \[c \approx 7.07\][/tex]
Therefore, the length of the hypotenuse (\(c\)) in this right triangle is approximately 7.07 units

A) 362,880
B) 347,760
C) 15,120
D) 3,024
The solutions for the given problems involving factorials and permutations are 8! = 40,320, 5P5 = 120, 8P4 = 1,680, 7P7 = 5,040 and the number of arrangement for 4 performers out of 9 is 3,024.
Explanation:The subject here is mathematics, specifically factorials and permutations. Factorials are represented by the symbol '!'. The factorial of a number n is the product of all positive integers less than or equal to n. For example, 8! = 8*7*6*5*4*3*2*1 = 40,320.
Permutations refer to the number of ways a set of objects can be arranged. 'nPn' always equals to the factorial of n, therefore 5P5 equals to 5! = 5*4*3*2*1 = 120 and 7P7 equals to 7! = 7*6*5*4*3*2*1 = 5,040.
'nPm' equals to n factorial divided by (n-m) factorial. So, 8P4 equals to 8!/(8-4)! = (8*7*6*5)/1 = 1,680.
For the last question, the number of ways 4 performers can stand in a row out of 9, is calculated as a permutation of '9P4' (because the order of performers matters). Thus, it will be 9!/(9-4)! = 9*8*7*6 = 3,024.

rectangular prism
Answer:
It is the Rectangular Prism.
Step-by-step explanation:
Sry, I don't have enough time to write out an explanation. Hope the answer helped!
Answer:
the cylinder container has the greatest surface area.
Step-by-step explanation:
The volume of cone is calculated by [tex]v=\frac{1}{3}\times\pi\times r^{2}\times h[/tex]
The volume of cylinder is calculated by [tex]v=\pi\times r^{2}\times h[/tex]
The volume of square pyramid is calculated by [tex]v=\pi\times r^{2}\times h[/tex]
The volume of rectangular prism is calculated by [tex]v=\frac{1}{3}\times B\times h[/tex]
The radius of cone is [tex]\frac{6}{3}[/tex]=[tex]2in[/tex], and slant height is 10 in.
height is calculated as h² = l²- r²
h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54
The volume of cone is [tex]=\frac{1}{3}\times 3.14\times 3^{2}\times 9.54[/tex]
[tex]=\frac{1}{3}\times 3.14\times 9\times 9.54[/tex]
v=89.8668
The volume of cylinder is [tex]=3.14\times 3^{2}\times 10[/tex]
[tex]=3.14\times9\times 10[/tex]
v=282.6
The volume of square pyramid
The height of pyramid is calculated as h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54
[tex]v=3.14\times 3^{2}\times 9.54[/tex]
[tex]v=3.14\times 9\times 9.54[/tex]
[tex]v=269.60[/tex]
The volume of rectangular prism[tex]v=\frac{1}{3}\times 6\times 10[/tex]

The width of a picnic table is 3 times its length. If the length is 5/6 yd long, what is the area of the picnic table in square feet?
Answer:
The area of the picnic table is [tex]18.75\ ft^{2}[/tex] or [tex]18\frac{3}{4}\ ft^{2}[/tex]
Step-by-step explanation:
we know that
[tex]1\ yd= 3\ ft[/tex]
Let
L-----> the length of the table
W----> the width of the table
the area of the table is
[tex]A=LW[/tex]
Convert yards to feet
[tex]L=\frac{5}{6}\ yd=\frac{5}{6}*3=\frac{5}{2}\ ft[/tex]
[tex]W=3L[/tex]
[tex]W=3(\frac{5}{2})=\frac{15}{2}\ ft[/tex]
substitute in the formula
[tex]A=\frac{5}{2}(\frac{15}{2})=\frac{75}{4}=18.75\ ft^{2}[/tex]
To calculate the area of the picnic table, convert the length to feet and multiply by the width, also in feet, to find the area in square feet.
Explanation:The student is asking about the area of a picnic table in square feet when the width is 3 times the length and the length is given as 5/6 yard. To find the area, first, calculate the width by multiplying the length of 5/6 yard by 3, which gives 5/2 yards (or 2.5 yards).
Since there are 3 feet in a yard, we convert the measurements to feet: 5/6 yard is equal to 5/6 * 3 feet, and the width is 2.5 * 3 feet. Next, multiply the length and width in feet to find the area.
It is important to note that converting measurements should retain unit consistency throughout the calculation.

3 A classroom is arranged with 8 seats in the front row, 10 seats in the mid
Answer:
Option F. [tex]200.96\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
in this problem
[tex]D=64\ ft[/tex]
substitute
[tex]C=\pi (64)=64\pi\ ft[/tex] -----> exact value of the circumference
Find the approximate value of the circumference
assume
[tex]\pi=3.14[/tex]
[tex]64\pi\ ft=64(3.14)=200.96\ ft[/tex]
The correct answer is option F. The measurement is closest to the circumference of the base of the observatory is 200.96 ft.
To find the circumference of the base of the observatory, we use the formula for the circumference of a circle, which is [tex]\( C = \pi \times d \)[/tex], where [tex]\( C \)[/tex] is the circumference and [tex]\( d \)[/tex] is the diameter of the circle.
Given that the diameter of the floor of the observatory is 64 feet, we can plug this value into the formula:
[tex]\( C = \pi \times 64 \) feet[/tex]
Using the approximation [tex]\( \pi \approx 3.14159 \)[/tex], we calculate the circumference as follows:
[tex]\( C \approx 3.14159 \times 64 \)[/tex] feet,
[tex]\( C \approx 200.96 \)[/tex] feet.
The complete question is:
An observatory is shaped like a cylinder standing on one of its bases with a dome on top. The diameter of the floor of the observatory is 64 feet, as shown in the diagram.

Which inequality represents all possible solutions of -6n < -12?
The inequality -6n < -12 has all numbers greater than 2 as its solution after isolating 'n'. We achieve this by dividing both sides by -6 and flipping the inequality sign.
Explanation:To solve this inequality, -6n < -12, you first need to isolate 'n' on one side of the inequality. We do this by dividing both sides of the inequality by -6. It's important to remember that when we divide or multiply an inequality by a negative number, we need to flip the direction of the inequality sign. So, the inequality would become n > 2. This means that all numbers greater than 2 are the solutions of the inequality.

The adult population of a town in 2000 was 400. The child population of the town in 2000 was 120. Both the adult and child populations increased by the same percent from 2000 to 2010. If the adult population in 2000 was 500, how many children lived in the town then?
Answer:
150
Step-by-step explanation:
500 is 125% of 400 (500/400) so you need to get what 125% of 120 is
120 x 1.25 =150
^number of children ^125% as a decimal
To find the number of children after the same percent increase in population as the adults, calculate a 25% increase based on the adult growth from 400 to 500. Applying this to the original child population (120), there were 150 children in 2010.
The question pertains to the percent increase in population and requires finding the number of children in a town given the increase in adult population. Specifically, the child population in 2000 was 120, and the adult population increased from 400 to 500 from 2000 to 2010. Assuming that the child population increased by the same percent as the adult population, we need to calculate this percentage increase and then apply it to the number of children to find the updated child population in 2010.
To find the percentage increase in the adult population:
Calculate the increase by subtracting the original number from the new number (500 - 400 = 100).Divide the increase by the original number (100 / 400 = 0.25).Convert the decimal to a percentage by multiplying by 100 (0.25 × 100 = 25%).Since the child population increased by the same percentage, we then:
Apply the 25% increase to the original child population (120).Multiply 120 by 0.25 to find the increase (120 × 0.25 = 30).Add the increase to the original child population (120 + 30 = 150).Therefore, there were 150 children in the town in 2010.
Solve the equation. −5 = c7
