In probabilities, variables p and q are often used as complements of another.
The value of q is 0.421The value of p is 0.129The relationship between variables p and q is:
[tex]\mathbf{p+ q = 1}[/tex]
So, we have:
(a) p = 0.579
Substitute 0.579 for p in [tex]\mathbf{p+ q = 1}[/tex]
[tex]\mathbf{0.579 + q = 1}[/tex]
Make q the subject
[tex]\mathbf{q = 1 - 0.579}[/tex]
[tex]\mathbf{q = 0.421}[/tex]
The value of q is 0.421
(b) q = 0.871
Substitute 0.871 for q in [tex]\mathbf{p+ q = 1}[/tex]
[tex]\mathbf{p + 0.871 = 1}[/tex]
Make p the subject
[tex]\mathbf{p = 1 - 0.871}[/tex]
[tex]\mathbf{p = 0.129}[/tex]
The value of p is 0.129

Which matrix multiplication is defined ?
Answer:
A. CB
Step-by-step explanation:
3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.
A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.
If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.

Han is multiplying 10x^4 by 5x^3 and gets 5x^7. He says that 0.5x^3 is not a polynomial because 0.5 is not an integer. What is the error in Han’s thinking? Explain your reasoning.
The result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong
Given the polynomial functions
r(x) = [tex]10x^4[/tex]
t(x) = [tex]5x^3[/tex]
Taking the product of both functions:
P(x) = r(x) * t(x)
P(x)= [tex]10x^4\times 5x^3[/tex]
P(x) = [tex](10\times 5) \times(x^4\times x^3) = 50x^7[/tex]
Comparing the result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong.

Fred's family wants to switch cell phone plans. Hot Spot Mobile is offering a one-time discount of $50 for families that use multiple phones with their service. Fred's family uses 5 phones, and the salesperson said the first month's payment, which includes the discount and the regular monthly rate for each phone, will be $62.25. What is the regular monthly rate for each phone?
Answer:
22.45
Step-by-step explanation:
ixl told me a
Answer:
$22.45 per month
Step-by-step explanation:
Fred's family will pay for cell service for 5 phones at a regular monthly rate of c dollars for each phone. They will also receive a discount of $50. The first month's payment will be $62.25. This equation represents the situation.
5c
−
50
=
62.25
monthly cost of cell service for 5 phones
one-time discount
first month's payment
Now, solve the equation for c.
5c–50
= 62.25
5c
= 112.25 Add 50 to both sides
c
= 22.45 Divide both sides by 5
The regular monthly rate for each phone is $22.45.
Which of these represents the conjugate of the impedance of a circuit written as 7 – i ohms?
A
–7 – i ohms
B
–7 + i ohms
C
–7i ohms
D
7 + i ohms
For the expression 7 - i ohms, the conjugate will be 7 + i ohms (the sign was changed from negative to positive)
The impedance of the circuit is written in form of a complex number.
The standard representation of a complex number is expressed as a + ib where:
a is the real part
ib is the imaginary part
The conjugate of the complex number a + ib will be a - ib. Note that the signs of the expression were changed from addition to subtraction.
Similarly for the expression 7 - i ohms, the conjugate will be 7 + iohms (the sign was chaged from negative to positive)

a. Let x represent the number of monthly calls. The answer is
(Type an inequality.)
Answer:
After 460 calls plan 1 is more economical than plan 2
Step-by-step explanation:
Plan 1: 36x + 0y
Plan 2: 13x + 0.05y
36x < 13x + 0.05y
36x - 13x < 0.05y
23x < 0.05y
23/0.05x < y
460x < y
