Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles in a quadrilateral is 360°. This means:
x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this
3 1/2x - 25 = 360° - now add 25 to both sides
3 1/2x = 385 - finally divide both sides by 3 1/2
x = 385 ÷ 3.5 = 110
x = 110°

The graph of g is a translation 1 unit down of the graph of f(x) = 3|x| – 4. The rate of change of g over the interval 2 ≤ x ≤ 5 is
The solution is: the rate of change is 3.
Here, we have,
Since the graph of f(x) is translated 1 unit down, we need to decrease the value of f(x) by 1 to find g(x):
g(x) = f(x) - 1
f(x) = 3|x| – 4
so, we get,
g(x) = 3|x| – 4 - 1
= 3|x| – 5
Now, to calculate the rate of change over the interval 2 <= x <= 5, we can use the formula below:
rate = g(5) - g(2)/ 5-2
so, we get,
rate = 9/3 = 3
Therefore the rate of change is 3.

Answer:

write the inequality shown -4x+y=-3
The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.
To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.
Starting with -4x + y = -3, we isolate y by adding 4x to both sides:
y = 4x - 3
Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.
If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:
y > 4x - 3
If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:
y < 4x - 3
The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.
For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.

Looking at the diagram, there is a transversal cutting across 2 parallel lines.
Angle 2 and angle 6 lie in similar position on the same side of the transversal. This means that they are corresponding angles. Corresponding angles are equal.
Given that angle 2 = 32 degrees, then angle 6 = angle 2 = 32 degrees
angle 5 and angle 6 are linear pairs. They lie on a straight line. the sum of the angles on a straight line is 180 degrees. It means that
angle 5 + angle 6 = 180
angle 5 + 32 = 180
angle 5 = 180 - 32
angle 5 = 148 degrees

suppose there is a normally distributed population with a mean of 250 and a standard deviation of 50. if xbar is the average of a sample of 36, find P(246
Using the normal distribution and the central limit theorem, it is found that:
\(P(246 \leq \bar{x} \leq 260) = 0.5693\)
Normal Probability DistributionIn a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).In this problem:
The mean is of \(\mu = 250\).The standard deviation is of \(\sigma = 50\).A sample of 36 is taken, hence \(n = 36, s = \frac{50}{\sqrt{36}} = 8.3333\).The probability of a sample mean between 246 and 260 is the p-value of Z when X = 260 subtracted by the p-value of Z when X = 246, hence:
X = 260:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{260 - 250}{8.3333}\)
\(Z = 1.2\)
\(Z = 1.2\) has a p-value of 0.8849.
X = 246:
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{246 - 250}{8.3333}\)
\(Z = -0.48\)
\(Z = -0.48\) has a p-value of 0.3156.
0.8849 - 0.3156 = 0.5693, hence:
\(P(246 \leq \bar{x} \leq 260) = 0.5693\)

{1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 5}
The lower quartile is the median of the lower half of the data set. Since there are an even number of data points, we take the average of the middle two values:
Lower quartile = (2+2)/2 = 2

if we notice the tickmarks on the triangle, we can see the all sides are equal, namely is an equilateral triangle, and if all sides are equal, then all interior angles are equal as well.
Let's recall that the sum of all interior angles in a triangle is 180°, now if we divide that by 3, that gives us 60, namely each angle in the equilateral triangle is 60°, that means
\(10x=60\implies x=\cfrac{60}{10}\implies \boxed{x=6} ~\hfill 12y=60\implies y=\cfrac{60}{12}\implies \boxed{y=5}\)

Twice the difference of a number and 9 is equal to three times the sum of the number and 8.
The number= -25
Step-by-step explanation:
To solve this equation, you can start by expressing the difference between the number and 9 as 2 times the sum of the number and 8 divided by 3. This gives you the equation:
2 * (x + 8) / 3 = x - 9
You can then multiply both sides of the equation by 3 to get rid of the fraction:
6 * (x + 8) = 3 * (x - 9)
This simplifies to:
6x + 48 = 3x - 27
You can then combine like terms on both sides of the equation to get:
3x + 48 = -27
You can then add 27 to both sides of the equation to get:
3x + 75 = 0
You can then subtract 75 from both sides of the equation to get:
3x = -75
You can then divide both sides of the equation by 3 to get the solution:
x = -25
Therefore, the number x is equal to -25.

The short leg of a right triangle is 10 meters and the acute angles measure 25° and 65°. find the measures of the longer leg of the right
triangle.
When the short leg of a right triangle is 10 meters long and the sharp angles are present, the right triangle's longer leg has a measurement of 21.45 meters.
what is right angle ?Right angles are created when two straight lines cross at a 90° angle or are perpendicular to one another at the intersection. The sign stands for a right angle. Different right angle formations can be seen in the above image. The proper angles can be found in shapes. Right triangles are triangles with one of the internal angles at a right angle of 90 degrees. Since a triangle's three interior angles sum up to 180 degrees, a right triangle's three interior angles must always add up to 90 degrees since one of them is always 90 degrees.
given
x / sin 65° = 10 / sin 25°
x = 10 sin 65°/ sin 25°
x = 21 .45 meters
