The product of a complex number and its complex conjugate is
a real number.

Answer:

Number 2: -3/10 (I think)

Number 4: 10a-5b-4

Number 6: x=5/2

Number 8: x=6

Step-by-step explanation:

Number 2:

3ysquared/2y-4x2

3(-1)squared/2(-1)-4x2

3x1/2(-1)-4x2

3x1/-10

-3/10

(I might be wrong with this one though)

Number 4:

10a-3b-4-2b

10a-5b-4

Number 6:

2(-3x+8)=4x-9

-6x+16=4x-9

-6x+16-16=4x-9-16

-6x=4x-25

-6x-4x=4x-25-4x

-10x=-25

-10x/-10=-25/-10

x=5/2

Number 8:

1(4x-8)/4=-x+10

4x-8/4=-x+10

4x-8/4+x=-x+10+x

8x-8/4=10

4x8x-8/4=4x10

8x-8=4x10

8x-8=40

8x-8+8=40+8

8x=48

8x/8=48/8

x=6

Answer: 67

Step-by-step explanation:

When you multiply with numbers like 10, 100, 1000, 10000, and so on you just have too right or left (division : left)(multiplication : right) according to the zero's. Like 100 has 2 zero's so then if you're multiplying with that you will go 2 to the right, and dividing you will go 2 to the left. Lets apply the same logic here, the question is 6.7 x 10, 10 has 1 zero and we are multiplying here so then, we have to go to the right, so 6.7 will become 67.

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the population variance, we first need the mean:

[tex]\bar{x}=\frac{4+6+8+9+9}{5}=\frac{36}{5}=7.2[/tex] so the mean is 7.2. To find the population variance (which is almost exactly the same as the sample variance except for a small difference in the denominators of the formula) we have to take each number minus the mean, and then square the difference. Add together all these squared numbers and then divide by the number of numbers. Like this:

[tex](4-7.2)^2=10.24\\(6-7.2)^2=1.44\\(8-7.2)^2=.64\\(9-7.2)^2=3.24\\(9-7.2)^2=3.24[/tex]

Add together those numbers and divide them by 5:

[tex]\sigma=\frac{10.24+1.44+.64+3.24+3.24}{5}=\frac{18.8}{5}=3.76[/tex]

Step-by-step explanation:

1/2x = -3

x = -6

4x + 34

4*(-6) + 34

-24 + 34 = 10

Step-by-step explanation:

[tex]3(2x - 5) = 6(x + 3)[/tex]

[tex]6x - 15 = 6(x + 3)[/tex]
