Answer:
please give me brainlist and follow
Step-by-step explanation:
Correct option is
A
5/7
As A and B are independent
0.8=P(A∪B)=P(A)+P(B)−P(A)P(B)
=0.3+P(B)−(0.3)P(B)
⇒0.5=(0.7)P(B)⇒7P(B)=5
If you know how to do this correctly, please help me!! Thank you. 30 points :)

Dante is mailing a box with a length of nine 1/2 inches a width of 8 inches and a height of 6 inches what is the volume of the box
Answer:
456 in³
Step-by-step explanation:
To find the volume of the box, use the volume formula, V = lwh
Plug in the length, width, and height:
V = lwh
V = (9.5)(8)(6)
V = 456
So, the volume of the box is 456 in³

What is the distance between points (4,214) ( 4 , 2 1 4 ) and (4,712) ( 4 , 7 1 2 ) on a coordinate grid?
Answer:
5 1/4 units
Step-by-step explanation:
Determine number of solutions
What is the slope-intercept form of this equation?
8x + y = 12
Answers:
Y= 2/3x + 2
Y= 4/3x + 6
Y= -4/3x + 6
Y= -4/3x + 2
Answer:
y = -8x + 12
Step-by-step explanation:
Slope intercept form: y = mx + b
m ---> Slope & b ----> y-intercept
8x + y = 12
Subtract 8x from both sides
y = -8x + 12

Use matrix method to solve 2+y=3,x+2y=9
Answer:
x= -1, y= 5
Step-by-step explanation:
Please see the attached picture for the full solution.
Matrix A is called the coefficient matrix. This means that its elements are the coefficient of x and y. In matrix X, write the unknown variables. Then write the constants in matrix B.
Theorem:
[tex]{A}^{ - 1} A = I[/tex]
☆ I is an identity matrix and can be treated as 1 when multiplying.
[tex] {A}^{ - 1} = \frac{1}{ |A| } adj(A)[/tex]
☆ [tex] |A|[/tex] is the determinant of A
☆ adj(A) is the adjoint of matrix A
Use the distributive property to rewrite the expression -1 (x -2)
Answer:
Step-by-step explanation:
Distributive property: a*(b + c) =(a*b) + (a*c)
Multiply x by (-1) and (-2) by (-1)
-1(x - 2 ) = (-1)*x - 2 *(-1)
= -x + 2

9.4 + p - 9.4 = 4.8 - 9.4
p = -4.6
Answer: p=-4.6
Step-by-step explanation:
you need to rearrange the terms first.
9.4+p=4.8
p+9.4-9.4=4.8-9.4
p=-4.6 after you subtract

what is the vaule of x ?
Answer:
5
Step-by-step explanation:
(5x + 10) + 55 = 90
5x + 10 + 55 = 90
5x + 65 = 90
5x + 65 - 65 = 90 - 65 (the 65 crosses off)
5x = 25
5x/5 = 25/5
x = 5
