A sample of students is taken from the school's A honor roll. The school
estimates that there are actually 360 students on the A honor roll. Using this
sample, how many students on the A honor roll are 8th graders?
6th: 15
7th: 11
8th: 14
Please help don’t just like the others that don’t really help
Answer:
Number of 7th Graders= 360 - X
Step-by-step explanation:
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from &th grade. As we know: Total number of students on the A honor roll = 360 We are asked to calculate, number of students from 7th grade on the A honor roll. So, let's assume that "X" represents the all the students who are on the A honor roll except 7th grade. Mathematical Expression: Number of 7th Graders = Total number of students on the A honor roll - X Number of 7th Graders = 360 - X So, if you know the value of X, you can easily calculate the number of students which are from 7th grade on the A honor roll.

Answer:
B) V= 4/3πr^3
Step-by-step explanation:
The volume of the cone according to the given condition is V = 4πr³/3
What is cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.
Given that the height of a cone is two times its base diameter. we need to find the formula for the volume of cone in terms of base radius,
So, the volume of a cone in general is = π × radius² × height/3
According to the question,
The height is 2x the base diameter, that mean =
h = 2d
Since, d = 2r
So, h = 2(2r)
h = 4r
So the volume according to this condition is =
π × r² × 4r/3
V = π × 4r³/3
V = 4πr³/3
Hence the volume of the cone according to the given condition is V = 4πr³/3

Step-by-step explanation:
First change m into cm
20m -> 2000cm
2m -> 200cm
volume of wall = 2000×200×60
=> 24000000 cm³
volume of each stone = 20×30×10
=> 6000 cm³
stone needed = 24000000/6000

help me find x for both, please?
Some General Information:
⇒ both triangles are isosceles triangle
⇒because two of the angles are equal to each other
⇒ which means there are two equal sides that always join at the
same angle to the base (the third side), and meet directly above
the midpoint of the base (I attached a diagram for a better
explanation)
Question 11:
⇒ x and 10 are equal
⇒ because their sides join the third side at the base with the same
angle
⇒ so x = 10
Question 12:
⇒ '2x + 23' and 7 are equal
⇒ because their sides join the third side at the base with the same
angle
⇒ so:
[tex]2x+23=7\\2x=-16\\x = -8[/tex]
⇒ thus x = -8

Find all solutions to the equation
in the interval [0, 27). Enter the
solutions in increasing order.
cos 2x + cos x = 0
It looks like the equation is
cos(2x) + cos(x) = 0
Use the double angle identity for cosine to write this as
(2 cos²(x) - 1) + cos(x) = 0
2 cos²(x) + cos(x) - 1 = 0
Factorize the left side:
(2 cos(x) - 1) (cos(x) + 1) = 0
Then either
2 cos(x) - 1 = 0 or cos(x) + 1 = 0
2 cos(x) = 1 or cos(x) = -1
cos(x) = 1/2 or cos(x) = -1
[x = cos⁻¹(1/2) + 2nπ or x = -cos⁻¹(1/2) + 2nπ]
… or [x = cos⁻¹(-1) + 2nπ]
(where n is any integer)
x = π/3 + 2nπ or x = -π/3 + 2nπ or x = π + 2nπ
We get the following solutions in the interval [0, 2π):
x = π/3 and x = π and x = 5π/3

The functions f(x) and g(x) are different functions.
How to explain the function?The function f(x) is a cubic function, while the function g(x) is a logarithmic function. The common feature of both functions is their range
The functions are given as:
f(x) = x³ + x² - 2x + 3 and g(x) = log(x) + 2
This means that the function f(x) is a cubic function, while the function g(x) is a logarithmic function.
From the attached graph, we have the following features:
Domain: -∞ < x < ∞
Range: -∞ < y < ∞
y-intercept = 3
x - intercepts = -2.37
Function g(x)
Domain: x > 0
Range: -∞ < y < ∞
y - intercept = None
x - intercepts = 0.01

What is the domain
Answer:
Step-by-step explanation:
The domain is the allowed 'x' values that the function can take on without it being undefined. The natural log function is undefined for negative numbers and zero. It can only take on positive inputs. Therefore, we can set up an inequality:
[tex]3-4x > 0[/tex]
Subtrauct 3 on both sides:
[tex]-4x > -3[/tex]
Divide both sides by -4. When you divide an inequality by a negative number, you must switch the sign of the inequality:
[tex]x < 3/4[/tex]
Therefore, our allowed 'x' values is anything less than 3/4:
-∞ < x < 3/4

Anvils Works' requires, on average, 2,500 tons of aluminum each week, with a standard deviation of 800 tons. The lead time to receive its orders is 11 weeks. The holding cost for one ton of aluminum for one week is $11. It operates with a 0.98 in-stock probability. Use Table 11.5.
Suppose its on-hand inventory is 5050 tons, on average. What in-stock probability does it offer to its customers?
Based on the inventory on hand, the lead time, and the standard deviation, the in-stock probability will be 96.56%
What is the in-stock probability?To find the in-stock probability, you first need to find the Z score as:
= On-hand inventory / Standard deviation x √(lead time + 1)
Solving gives:
= 5,050 / 800 x √(11 + 1)
= 5,050 / 2,771.28
= 1.82
With a Z score of 1.82, the probability according to the Z tables will be 96.56%

PLEASE HELP ASAP! Find the volume of the prism.
Answer:
5 * sqrt(3)
Step-by-step explanation:
First, find the area of the triangle. Do this by determining the height of the triangle. The main triangle is really two right triangles, so do half of it at a time. This causes the base to become one.
According to the Pythagorean Theorem, the height is the square root of 3.
The area of one half of the triangle is sqrt(3)/2, but you need to double that to find the whole triangle's area, so the whole area is sqrt(3).
Now just multiply by 5.
The answer is 5 * sqrt(3), the one you have selected in the image.
