Based on the corresponding angles theorem, since lines m and n are parallel lines, the value of x = -3.

The corresponding angles that are formed when two parallel lines are intersected by a transversal are congruent, according to the corresponding angles theorem.

Given that lines m and n are parallel lines that are intersected by transversal t, therefore:

2x + 9 = 7x + 24

Solve for x

2x + 9 - 9 = 7x + 24 - 9 [subtraction property of equality]

2x = 7x + 15

2x - 7x = 7x + 15 - 7x [subtraction property of equality]

-5x = 15

-5x/-5 = 15/-5 [division property of equality]

x = -3

Therefore, based on the corresponding angles theorem, since lines m and n are parallel lines, the value of x = -3.

Answer: 124.3%

Step-by-step explanation:

318.2/256=1.24296875

1.24296875*100=124.296875

124.296875=124.3%

Since 318.2 is greater than 256, the percent is going to be greater than 100, because the number 318.2 is more than 100 of 256 which basically translates to 318.2 being greater than 256.

Binomial distribution describes the variety of successes k accomplished in n trials, wherein opportunity of achievement is p. Geometric distribution is a unique case of bad binomial distribution, wherein the test is stopped in the beginning failure (r = 1).

The not common definition of the Geometric distribution is the variety of trials till the primary achievement.. The following is an instance for the distinction among the Binomial and Geometric distributions: If a own circle of relatives comes to a decision to have five youngsters, then the variety of girls (successes) within side the own circle of relatives has a binomial distribution. If the own circle of relatives comes to a decision to have youngsters till they have got the primary lady after which stop, the the variety of youngsters within side the own circle of relatives has a Geometric distribution . A variant at the Geometric distribution is counting the variety of failures till the primary achievement, after which the variety may be 0,1,2,... In the instance it might be counting the variety of boys within side the own circle of relatives earlier than the primary lady turned into born, and now no longer the entire variety of youngsters. The distinction among the 2 versions is usually 1.

Answer:

x = 6

Step-by-step explanation:

2x + 4 = 3x - 2

2x - 3x = -2 - 4

-x = -6

x = 6

Answer:

x = 6

Step-by-step explanation:

We are given this equation:

2x + 4 = 3x - 2

And we want to evaluate the equation for x.

To do this, we need to isolate the variable (x) on one side of the equation.

We can start by putting the numbers on one side.

We can subtract 4 from both sides of the equation to start. Remember that when solving equations, whatever we do on one side of the equation, we need to do it on the other side as well.

2x + 4 = 3x - 2

     -4          -4

___________________

2x = 3x - 6

Now, let's put the variables on the other side.

Subtract 3x from both sides.

2x = 3x - 6

-3x   -3x

______________

-x = -6

Now, the numbers and variables are on different sides, however we are not done yet, as we need to take care of the negatives, as x shouldn't be negative in this case.

-x is the same as -1x, or -1 * x.

So, in order to get rid of the negatives, we can either multiply or divide both sides by -1.

Let's multiply both sides by -1.

-1(-x) = -1(-6)

x = 6

The value of x is 6.

A guardrail's acceptable height range is 99cm to 113cm and the definite absolute value inequality is as follows | h - 106cm | ≤ 7cm,

We understand that the height must be 106cm with a maximum absolute deviation of 7cm.

As a result, the maximum height is:

106cm plus 7cm = 113cm

The bare minimum is:

99cm = 106cm -7cm

This is represented by the absolute value equation:

| h - 106cm | ≤ 7cm

In which h is the guardrail's height.

A guardrail's acceptable height range is 99cm to 113cm.

The slope of the line is zero.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope or gradient. In the coordinate plane, it represents the slope of the line.

From the given figure we can see that the line is parallel to the x-axis.

Any line parallel to the x-axis is given by the general equation y = a .

This equation can also be written as:

y = 0 x + a.

Comparing the above equation with the general equation of a straight line  y = mx + c

we see m = 0 and c = a (a is a constant)

Hence the slope of the line is 0.

To the nearest tenth of a mile, the length of one side of this tract of land is 0.64 miles

This problem can be solved by using the concept of scale factor. Scale factor is useful in finding proportional measurements.

Proportion implies having the same ratio.

Scale factor can be defined as the ratio of the measurement of the model to the measurement of the actual form in the simplest form. In other words, the ratio of any two corresponding lengths in two similar geometric figures is called a scale factor.

If the scale factor is more than 1, that is, scale factor > 1,

then it is an enlargement,

If the scale factor is less than 1, that is, scale factor < 1,

then it is a reduction.
