Answer:

x = -2

y = 2

Step-by-step explanation:

Take the value of x from the first equation: x = 2 − 2 y ( 1 ) , and substitute for x into the second: y = 2 ( 2 − 2 y ) + 6 solve for y ; y = 4 − 4 y + 6 y = 10 5 = 2 Substitute back into ( 1 ) and find x : x = 2 − 4 = − 2

We're dealing with percentage. hence, our universal set: U=100%.

Let:A = set of those that read magazine A

B = set of those that read magazine B

C = set of those that read magazine C

(i) we are looking for n{(A n B) u (B n C)}

so, n{(A n B) u (B n C)} = n(A n B) + n(B n C) -n(A n B n C)

n{(A n B) u (B n C)} = 20% + 30% - 10%

: n{(A n B) u (B n C)} = 40%

(ii) We're looking for {A' n B' n C'}

{A' n B' n C'} = n(U) - n(A u B u C)

{A' n B' n C'} = 100% - n(A u B u C)

n(A u B u C) = n(A) + n(B) + n(C) - n{(A n B) - n(A n C) -n(B n C) + n(A n B n C)

n(A u B u C) = 60% + 50% + 50% -30% - 30% - 20% + 10%

n(A u B u C) = 90%

however, {A' n B' n C'} = 100% - n(A u B u C)

: {A' n B' n C'} = 100% - 90%

{A' n B' n C'} = 10%

Answer:

y = 3

Step-by-step explanation:

Subtract 3 from both sides of the equation

y + 3-3 = -y + 9-3

Simplify

y = -y + 6

Add y to both sides of the equation

y+y=-y+6+y

Simplify

2y = 6

Divide both sides of the equation by the same term

2y/2 = 6/2

Simplify

y = 3

[RevyBreeze]

The solution of the Equation is y= 3.

We have, the equation is

y + 3 = -y + 9

y + y = 9 - 3

2y = 6

Now, divide both side we get

2y = 6

2y/ 2 = 6/ 2

y = 3

Thus, the solution of y is 3.

= 3(x+2)+1

Answer: -5

Step-by-step explanation:

You have to find a. Here's some steps you can take.

1.) Subtract 12 on the left side of the equal sign to get -6a by itself. When subtracting 12 you must subtract 12 from 42 as well.

2.) Your new equation would be -6a = 30

3.) Now you need to get a by itself. How do we do that? By dividing -6a by -6. REMEMBER: You must also do the same to the right side of the equal sign which is 30 (30/-6)

4.) Your problem should end up looking like this: a = -5

The number 4.905 can be written as in the expanded form 4x10⁰ + 9x10⁻¹ + 0.0x10⁻² + 5x10⁻³.

The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.

It is given that:

The number is 4.905

The number can be written in the expanded form as:

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

4.905 = 4x10⁰ + 9x10⁻¹ + 0.0x10⁻² + 5x10⁻³

Thus, the number 4.905 can be written as in the expanded form 4x10⁰ + 9x10⁻¹ + 0.0x10⁻² + 5x10⁻³.

Using the normal distribution, it is found that there is a 0.7452 = 74.52% probability of randomly selecting a vehicle with an engine between than 3.1 L and 4.2 L.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Researching the problem on the internet, it is found that:

The probability is the p-value of Z when X = 4.2 subtracted by the p-value of Z when X = 3.1, hence:

X = 4.2

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{4.2 - 3.59804}{0.47986}[/tex]

[tex]Z = 1.25[/tex]

[tex]Z = 1.25[/tex] has a p-value of 0.8944.

X = 3.1

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{3.1 - 3.59804}{0.47986}[/tex]

[tex]Z = -1.04[/tex]

[tex]Z = -1.04[/tex] has a p-value of 0.1492.

0.8944 - 0.1492 = 0.7452.

0.7452 = 74.52% probability of randomly selecting a vehicle with an engine between than 3.1 L and 4.2 L.

Step-by-step explanation:

Interest rate has to be a decimal.

To convert percent to a decimal, divide by 100:

6.3% = 6.3/100 = 0.063
