Answer:
90 is the answer
Step-by-step explanation:
P(10,2) = [tex]\frac{10!}{(10-2)!}[/tex] = [tex]\frac{10!}{8!}[/tex] = [tex]\frac{10x9x8!}{8!}[/tex]
10x9
=90
The number of ways should be 90.
Calculation of no of ways:Since There are 10 doors to a coliseum.
So, here we used the permutation
[tex]= \frac{10!}{(10!-2!)}\\\\ = \frac{10!}{8!} \\\\= \frac{10\times 9\times 8!}{8!} \\\\= 10\times 9[/tex]
= 90

What is the domain and range of this function?
f(x) = logs(x - 2) + 1
OA.
domain: x > -2; range: all positive real numbers
OB.
domain: x> 2; range: all positive real numbers
OC. domain: x>-2; range: all real numbers
OD. domain: x> 2; range: all real numbers
Answer:
Domain = x > 2 , Range = {R}
Step-by-step explanation:
The given function to us is ,
[tex]\implies f(x) = log_{10} ( x - 2 ) + 1 [/tex]
Since logarithm are defined only for positive numbers therefore ,
=> (x - 2) > 0
=> x > 2
Therefore the domain of the function is x > 2 and it can have all positive real numbers .
3x = -6у + 3
2y = -x+1
Answer:
3x = -6у + 3 and 2y = -x+1 are the same
i dont know what the question is but this should help. they are the same line on a graph
Step-by-step explanation:
3x = -6y + 3
2y = -x + 1 adding x on both sides and subtracting 2y on both sides
x = -2y + 1 multiply by 3
3x = -6y + 3

Step-by-step explanation:
To find the surface area you just need to find the area of every side of the box and add them together.
SO- the equation for this would be
SA (Surface Area) = 2(20 x 10) + 2(20 x 3) + 2(10 x 3)
SA = 2(200) + 2(60) + 2(30)
SA = 400 + 120 + 60
SA = 520 + 60
SA = 580

Answer:
x^2 =5
Step-by-step explanation:
Answer:
x² + 10x + 25 = 0
Step-by-step explanation:
Given that x = - 5 is a root then (x + 5) is a factor
Since it is a double root then (x + 5)² so equation is
(x + 5)² = 0 ← expand factor using FOIL
x² + 10x + 25 = 0

HELP
Answer:
d. The relative frequency of the people that chose drama is 0.1[tex]\overline 6[/tex]
e. The relative frequency of the people that chose action is 0.2
Step-by-step explanation:
The result of the survey is expressed as follows;
C, C, R, R, D, R, H, H, C, A, A, R, A, A, A, R, R, H, H, H, C, H, A, R, D, D, D, D, H, R

A, A, A, A, A, A, C, C, C, C, D, D, D, D, D, H, H, H, H, H, H, H, R, R, R, R, R, R, R, R
From the pivot table created with Microsoft Excel, we have
The frequency of As = 6
The frequency of Cs = 4
The frequency of Ds = 5
The frequency of Hs = 7
The frequency of Rs = 8
The sum of all frequency = 6 + 4 + 5 + 7 + 8 = 30
d. The relative frequency of the people that chose drama is given as follows;
[tex]Relative \, frequency = \dfrac{Frequency \ of \ observation}{Sum \ of \ all \ frequencies}[/tex]
The frequency of the people that chose drama = 5
The sum of all frequency = 30
[tex]Relative \, frequency \ of \ the \ people \ that \ chose \ drama = \dfrac{5}{30} = \dfrac{1}{6} = 0.1\overline 6[/tex]
The relative frequency of the people that chose drama = 0.1[tex]\overline 6[/tex]
e. The relative frequency of the people that chose action, RF action, is given as follows;
[tex]RF \ action = \dfrac{Frequency \ of \ the \ people \ that \ chose \ action}{Sum \ of \ all \ frequencies} = \dfrac{6}{30} = \dfrac{1}{5} = 0.2[/tex]
The relative frequency of the people that chose action, RF action = 0.2.

1,209 cm squared
955.5 cm squared
1,029 cm squared
Answer:
4. A = 1029 cm²Steps:
A = (35×21)+(21+2×3.5)×21/2
A = 735 + (21+7)×21/2
A = 735 + 28×21/2
A = 735 + 588/2
A = 735 + 294
A = 1029 cm²The sum of two numbers is 20. When the second number is subtracted from the first number, the difference is 4. Find the two numbers. What are the two numbers?

An artist is painting flower pots that each require 1/32 gallon of paint. What is the maximum number of flower pots the artist can paint with 3/4 gallon of paint?
Answer:
24 flower pots
Step-by-step explanation:
Fraction of paint required per flower pot = 1/32
Number of pots that can be painted with 3/4 galoons of paint :
Total Fraction of paint had / fraction of paint required per flower pot
3/4 ÷ 1/32
3/4 * 32 / 1
(3*32) / 4
96 /4
= 24 flower pots

Okay so i need to know the area of the rectangle on the inside its 5ft on the right side its 6ft and on the bottom its 5ft please and thank you :)
Answer:
30ft^2
Step-by-step explanation:
Area of a rectangle = Length * Width
Given
Length = 6ft
Width = 5ft
Substitute
Area of the rectangle = 6ft *5ft
Area of the rectangle = 30ft^2
Hence the area of the rectangle is 30ft^2
