Snow play ski park cost $35 entry fee and then $5 per hour. If you have $60, how long can you be at snow play ski park
Answers
Entry costs 35
Per hour is 5
60 - 35 = 25 left
5 per hour = 25/5
25/5 = 5 hours
Answer is 5 hours
For $60, you may spend four hours at Snow Play Ski Park.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Snow plays ski park costs a $35 entry fee and then $5 per hour. If you have $60
Let "x" be the hours you can play in the ski park
Since,
Addition charges = 35
Thus your total expenses to play x hours in the park = 5*x + 35
Since We have only 60$
So,
60 = 5x + 35
=> 5x = 25
=> x = 5
therefore, You can be at a snow play ski park for four hours for $60.

Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?
Answers
Answer: 16
Step-by-step explanation:
Find the mean absolute deviation of the data:
X : 92, 88, 90, 96, 84
Find the mean(m) of the data:
m = Σ(X) / n
n = number of samples
(92 + 88 + 90 + 96 + 84) / 5
m = 450 / 5
m = 90
Absolute Deviation of each value of the mean:
|x - m| :
|92 - 90| = 2
|88 - 90| = 2
|90 - 90| = 0
|96 - 90| = 6
|84 - 90| = 6
Σ|x - m| = 2 + 2 + 0 + 6 + 6 = 16

1. An equilateral triangle
2. A square
3. A regular pentagon
4. A regular hexagon
Answers
Answer:
A
Step-by-step explanation:
Cuz Im just right
(A) An equilateral triangle.
Circle:All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.Polygon:In geometry, a polygon is any closed curve made up of a collection of continuous line segments (sides) without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons are the three simplest polygons (five sides).Triangle:A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.Therefore, Ethan is in the process of constructing (A) an equilateral triangle.

Answers
Answer:
Explained below.
Step-by-step explanation:
The random variable X follows an exponential distribution with λ = 5.
The probability density function of X is:
[tex]f_{X}(x)=\lambda\cdot e^{-\lambda\cdot x};\ 0<x<\infty[/tex]
[tex]P(X\leq x)=1-e^{-\lambda\cdot x}\\\\P(X\geq x)=e^{-\lambda\cdot x}[/tex]
(a)
Compute the value of P (X ≤ 0) as follows:
[tex]P(X\leq 0)=1-e^{-\lambda\cdot x}[/tex]
[tex]=1-e^{-5\times 0}\\\\=1-1\\\\=0[/tex]
Thus, the value of P (X ≤ 0) is 0.
(b)
Compute the value of P (X ≥ 2) as follows:
[tex]P(X\geq 2)=e^{-5\times 2}=4.54\times 10^{-5}\approx 0[/tex]
Thus, the value of P (X ≥ 2) is approximately 0.
(c)
Compute the value of P (X ≤ 1) as follows:
[tex]P(X\leq 0)=1-e^{-\lambda\cdot x}[/tex]
[tex]=1-e^{-5\times 1}\\\\=1-0.00674\\\\=0.99326[/tex]
Thus, the value of P (X ≤ 1) is 0.99326.
(d)
Compute the value of P (1 ≤ X ≤ 2) as follows:
[tex]P(1<X<2)=\int\limits^{2}_{1} {5\times e^{-5x}} \, dx \\\\=5\times [\frac{e^{-5x}}{-5}]^{2}_{1} \\\\=5\times [\frac{0-0.00674}{-5}]\\\\=0.0067[/tex]
Thus, the value of P (1 ≤ X ≤ 2) is 0.0067.
(e)
Compute the value of x such that P (X < x) = 0.05 as follows:
[tex]P(X<x)=0.05\\\\\int\limits^{x}_{0} {5\times e^{-5x}} \, dx =0.05\\\\5\times [\frac{e^{-5x}}{-5}]^{x}_{0} =0.05\\\\1-e^{-5x}=0.05\\\\-e^{-5x}=0.95\\\\-5x=\ln(0.95)\\\\-5x=-0.05\\\\x=0.01\\\\[/tex]
Thus, the value of x is 0.01.

Find X to complete the following ratio. 12:5 = 24:X
Answers
Answer:
x = 10
Step-by-step explanation:
This is the answer because:
1) 12:5 is equivalent to the ration 24:10
2) This is because to get 24 you have to multiply 12 and 2 which is 24
3) Next, you have to do the same to the other side to make everything equal. Therefore, you have to multiply 5 with 2 which is 10.
4) Finally, your answer should be 24:10
