The BMW E30 is the second generation of BMW 3 Series, which was produced from 1982 to 1994 and replaced the E21 3 Series. The model range included 2-door sedan and convertible body styles,[4][5] as well as being the first 3 Series to be produced in 4-door sedan and wagon/estate body styles. It was powered by four-cylinder petrol, six-cylinder petrol and six-cylinder diesel engines, the latter a first for the 3 Series. The E30 325iX model was the first BMW to have all-wheel drive.

Answers

Answer: x=1/2

Step-by-step explanation: You want to get the x on one side of the equal sign, by itself. First you subtract (18/4) from both sides. 5 - (18/4) =1/2 So that’s your answer.

In a normally distributed data set with a mean of 24 and a standard deviation of 4.2, what percentage of the data would be between 19.8 and 28.2 and why

Answers

Answer:

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 24

Standard deviation = 4.2

What percentage of the data would be between 19.8 and 28.2

19.8 = 24 - 4.2

28.2 = 24 + 4.2

So within one standard deviation of the mean

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

what is the linear equation of (0.5,10) and -4.5,-10​

Answers

Answer:

The linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

[tex]y=4x+8[/tex]

Please check the attached graph also.

Step-by-step explanation:

Given the points

(0.5, 10)(-4.5, -10)

Finding the slope between (0.5, 10) and (-4.5, -10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0.5,\:10\right),\:\left(x_2,\:y_2\right)=\left(-4.5,\:-10\right)[/tex]

[tex]m=\frac{-10-10}{-4.5-0.5}[/tex]

Refine

[tex]m=4[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line(x₁, y₁) is the point

substituting the values m = 4 and the point (0.5, 10)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 10 = 4(x-0.5)[/tex]

Add 10 to both sides

[tex]y-10+10=4\left(x-0.5\right)+10[/tex]

Simplify

[tex]y=4x+8[/tex]

Therefore, the linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

[tex]y=4x+8[/tex]

For each expression, write an equivalent expression by applying the distributive
property.
2. (x + 4)(2x - 1)

Answers

2x^2 + 7x - 4 , i hope this helps

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

(x + 2) (x + 9)

(x + 4) (2x - 1)

(x - 5)²

Now,

Applying the distributive property.

1)

(x + 2) (x + 9)

x² + 9x + 2x + 18

x² + 11x + 18

2)

(x + 4) (2x - 1)

2x² - x + 8x - 4

Combining the like terms.

2x² + 7x - 4

3)

(x - 5)²

(x - 5) (x - 5)

x² - 5x - 5x + 25

x² - 10x + 25

Thus,

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25
