Answers
Answer: B
Step-by-step explanation:
The prime numbers here are outcomes 2, 3, and 5.
Therefore, we must add the frequency numbers for these prime numbers:
36 + 44 + 30 = 110
Out of 200 dice rolls, 110 were prime numbers. This can be represented as:
110/200 = 11/20 (fraction form)
= 0.55 (decimal form)
Therefore, the answer is b. 0.55

(1\6-1)(3-2/5)-(1/3-1/2)
Answers
Answer:
2 1/3 (simplified)
Step-by-step explanation:
(1/6 - 1) = -5/6
(1 = 6/6)
(3 - 2/5) = 2 3/5
[3= 18 (3 * 6)]
(1/3 - 1/2) = -1/6
(you can change both of the denominators to 6 by multiplying them both by 3 / 2
So the equation now is
(-5/6)(2 3/5) - (-1/6)
-5/6 * 2 3/5 = 2 1/6 (simplified)
2 1/6 - -1/6 = 2 1/3 (simplified)

Answers
9514 1404 393
Answer:
F = 3.84×10^23/R²
Step-by-step explanation:
No units are given for distance, so we cannot give a constant of proportionality that has suitable units.
The general form for inverse square variation is ...
F = k/R²
Then the value of k can be found from ...
k = F·R² = (6×10^5)(8×10^8)^2 = 3.84×10^23
The formula relating the given F and R is ...
F = 3.84×10^23/R²

(assuming the. values are the shaded areas)
area = x^2 + 2x +2
perimeter = 4x + 8
Step-by-step explanation:
you have all the side except the side of the 2 squares at the top.
The squares are 1 unit on each side because the area of the 2 slender rectangles on each side is x.
So the area is x^2 + x + x + 1 + 1
The perimeter is 1+x+1+1+1+x+1+1+1+x+1+x
(starting from the lower left side and walking around the perimeter clockwise)

Answers
a. Coefficient matrix A:
A = [[2, 3, 1],
[3, 3, 1],
[2, 4, 1]]
Augmented matrix [AL]:
[A|b] = [[2, 3, 1, -1],
[3, 3, 1, 1],
[2, 4, 1, -2]]
b. The resulting matrix will be [I|A^(-1)], where A^(-1) is the inverse of the coefficient matrix A.
c. The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.
a. The coefficient matrix A and the augmented matrix [A|b] for the given system of linear equations are as follows:
Coefficient matrix A:
A = [[2, 3, 1],
[3, 3, 1],
[2, 4, 1]]
Augmented matrix [AL]:
[A|b] = [[2, 3, 1, -1],
[3, 3, 1, 1],
[2, 4, 1, -2]]
b. To find the inverse of the coefficient matrix A using the Gauss-Jordan method, we perform elementary row operations until A is transformed into an identity matrix [tex][I|A^{(-1)][/tex].
Gauss-Jordan elimination steps:
Step 1: Perform row operations to convert the first column of A to [1, 0, 0]:
R1' = R1/2
R2' = R2 - (3/2)R1
R3' = R3 - R1
Step 2: Perform row operations to convert the second column of A to [0, 1, 0]:
R2'' = R2''/3
R1'' = R1'' - (3/2)R2''
R3'' = R3'' - (3/2)R2''
Step 3: Perform row operations to convert the third column of A to [0, 0, 1]:
R3''' = R3'''/2
R1''' = R1''' - R3'''
R2''' = R2''' - R3'''
The resulting matrix will be[tex][I|A^{(-1)][/tex], where [tex]A^{(-1)[/tex] is the inverse of the coefficient matrix A.
c. Once we have the inverse matrix A^(-1), we can find the solution set of the system of linear equations by multiplying A^(-1) with the augmented matrix [A|b]:
[A|b] [tex]\times[/tex] [tex]A^{(-1)[/tex] = [x1, x2, x3]
The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.
Note: To provide the numerical values for the inverse matrix [tex]A^{(-1)[/tex] and the solution set, the calculations need to be performed manually using the given coefficients of the equations.

find the least common multiple of 16,30,36 no links or file
Answers
9514 1404 393
Answer:
720
Step-by-step explanation:
The LCM of these numbers will have every factor that is part of these numbers.
16 = 2^4
30 = 2 × 3 × 5
36 = 2^2 × 3^2
So, the LCM will have factors of 2^4, 3^2, and 5:
LCM(16, 30, 36) = 2^4 × 3^2 × 5 = 720
720 = 16×45 = 30×24 = 36×20
The least common multiple is 720.
