Step-by-step explanation:

The answer is 9.1 because 13.65 divided by 1.5 equals 9.1

Answer:

x=47 degrees

Step-by-step explanation:

X equals 47 degrees because it is congruent to the other angle that is marked. This is because of Alternate Interior Angles.

We know AD and BC are parallel because the shape is a parallelogram, this means that the other line is a transversal. When you have a transversal going through two parallel lines there are certain rules, including Alternate Interior Angles, which are two angles on opposite sides of the transversal but both on the inside of the parallel lines.

Answer: They lie in different planes and will never intersect.

Step-by-step explanation:

Skew lines are lines that do not intersect and that also are not parallel. For example, if we were in a 2d dimensional space, the lines should intersect or be parallel, so from this, we know that skew lines only exist in 3d or above.

And also from that, we can conclude that skew lines are lines that do not intersect and must live in different planes.

Then the correct option is the first one:

They lie in different planes and will never intersect.

Answer:

A. They lie in different planes and will never intersect.

Add the ratio: 3 + 5 = 8

Divide total students by that:

32/8 = 4

The ratio for girls is 3, multiply the 4 by 3:

4 x 3 = 12

There are 12 girls

Answer:

12

Step-by-step explanation:

If the ratio of girls to boys is 3:5, that means that for every 8 total students, 3 would be girls and 5 would be boys. Therefore 3/8 of the students are girls and 5/8 are boys. If 3/8 are girls, then:

\(\frac{3}{8}\) of 32

= \(\frac{3}{8} * 32\)

\(=\frac{3 * 32}{8} \\= \frac{96}{8} \\= 12\)

There are 12 girls.

It sounds like you want to find how many diagonals a nonagon has.

A nonagon has n = 9 sides.

The number of diagonals would be...

\(d = \text{number of diagonals}\\\\d = \frac{n(n-3)}{2}\\\\d = \frac{9(9-3)}{2}\\\\d = \frac{9(6)}{2}\\\\d = \frac{54}{2}\\\\d = 27\\\\\)

A nonagon has 27 different diagonals.

The main idea behind statistical inference is that through the use of sample data, we are able to draw conclusions about the population from which the data was drawn (option c).

Statistical inference allows us to make inferences and draw conclusions about a larger population based on the analysis of a smaller representative sample.

By collecting data from a sample, we can use statistical methods to analyze and summarize the information. These methods include estimating population parameters, testing hypotheses, and making predictions.

The key assumption underlying statistical inference is that the sample is representative of the larger population, allowing us to generalize the findings to the population as a whole.

Statistical inference provides a way to make reliable and informed decisions, identify patterns and relationships, and make predictions about future observations based on the available data. It allows researchers, scientists, and decision-makers to make evidence-based conclusions and draw meaningful insights from limited observations.

The score at 35th percentile is 469.6 marks according to standard deviation and mean.

What is standard deviation?

Standard Deviation could be a measure that shows what quantity variation (such as unfold, dispersion, spread,) from the mean exis

Main body:

Given:

mean of μ = 500  and standard deviation of σ = 80

To answer this, we must find the z-score that is closest to the value 0.35 in the z table. This value turns out to be -0.38:

We can then plug this value into the percentile formula:

Percentile Value = μ + zσ

35th percentile = 500 + (-0.38)*80

35th percentile = 469.6

the score at the 15th percentile weighs about 469.6 marks.

Hence marks at 35th percentile is 469.6

Part a: The probability of hitting the black circle inside the target is closer to 0.

The black circle appears to be a relatively small area within the larger square-shaped target. Assuming Sophia's dart can hit any point within the target with equal probability, the probability of hitting the small black circle is lower compared to hitting any other point within the larger target area. Therefore, the probability of hitting the black circle is closer to 0 than to 1.

Part b: The probability of hitting the white portion of the target is closer to 1.

The white portion of the target comprises the majority of the square-shaped target area, excluding the black circle. Assuming Sophia's dart can hit any point within the target with equal probability, the probability of hitting the white portion is higher compared to hitting the small black circle. Therefore, the probability of hitting the white portion is closer to 1 than to 0.

Answer:

32,8+3,27=36,07

36,07-0,15=35.92

Step-by-step explanation:

The line that is parallel to AC and passes through B has the equation y: 1/5x + 12/5.

The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, also known as the y-intercept, and m is the gradient.

The benefit of expressing a linear equation in this way is that the values for m and b correspond to the slope and y-intercept, respectively.

This makes it easy to graph the line that the equation describes.

So, the slope of AC is:

6-1/1/2= 5/-1 = -5

The equation of line D, which passes through B and is perpendicular to AC, is given as y: mx + p.

Where p is the y value of the y-intercept point and m is the slope.

The fact that line D is perpendicular to line AC indicates that their slopes add up to one.

Therefore,

(−5) × m = −1

Now,

m = -1/-5 = 1/5

We discover that the D equation is:

Y: 1/5x + p

To complete the equation of D at this time, we still require the value of p.

B(3, 3)∈ D

3 = 1/5(3) + p

p = 3 - 3/5 = 12/5 = 2.4

Hence, equation D will be:

y: 1/5x + 12/5

Therefore, the line that is parallel to AC and passes through B has the equation y: 1/5x + 12/5.

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

(a) ∫cx ds for the straight line segment x=t, y=t⁵ from (0,0) to (20,4):

∫cx ds = ∫t * √(1 + 25t⁸) dt

(b) ∫cx ds for the parabolic curve x=t, y=t² from (0,0) to (3,9):

∫cx ds = ∫t * √(1 + 4t²) dt

What is the linear function?

A linear function is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

a. Evaluating ∫cx ds for the straight line segment x=t, y=t⁵ from (0,0) to (20,4):

First, we need to parameterize the curve. Let's define t as the parameter:

x = t

y = t⁵

Now, we can find the differential ds:

ds = √(dx² + dy²)

= √((dt)² + (5t⁴ dt)²)

= √(1 + 25t⁸) dt

Next, we substitute the parameterized values into the integral:

∫cx ds = ∫t * √(1 + 25t⁸) dt

Since the integral involves a square root, it might be difficult to find an exact solution. Numerical methods or approximation techniques may be required to evaluate this integral.

b. Evaluating ∫cx ds for the parabolic curve x=t, y=t² from (0,0) to (3,9):

Again, we parameterize the curve using t:

x = t

y = t²

Find the differential ds:

ds = √(dx² + dy²)

= √((dt)² + (2t dt)²)

= √(1 + 4t²) dt

Substitute the parameterized values into the integral:

∫cx ds = ∫t * √(1 + 4t²) dt

This integral may also require numerical methods or approximation techniques to evaluate it, as it involves a square root.

hence, (a) ∫cx ds for the straight line segment x=t, y=t⁵ from (0,0) to (20,4):

∫cx ds = ∫t * √(1 + 25t⁸) dt

(b) ∫cx ds for the parabolic curve x=t, y=t² from (0,0) to (3,9):

∫cx ds = ∫t * √(1 + 4t²) dt

Answer:

\(3^{10}\)

Step-by-step explanation:

\(3^{8}*3^{2}=3^{8+2}=3^{10}\)

Using the multiplication/product law of exponents, you can add the exponents up.

Answer:

3^10 and the law used would be the Product Rule for exponents.

Step-by-step explanation:

turning this question into an equation you would get:

3^8 * 3^2 = ?

The law you use in this situation is the product rule for exponents. If you have the same base number (in this case it is 3) with exponents and you are multiplying them, then you can add the exponent numbers and keep the base the same. This product rule looks like this:

A^x * A^y = A^(x+y)

Applying it to this question, you get

3^8 * 3^2 = 3^(8+2)

3^(8+2) is 3^10.

Therefore the simplified expression is 3^10.

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86
