Which pair is equivalent A:2/6 and 2/4 B: 3/6 and 1/2 C:5/12 and 1/3 D:4/8and 4/6

Answer:

you take the perimeter and subtract 2*the length. Then you divide that answer by 2

Step-by-step explanation:

This is because a rectangle is made up of 2 pairs of heights. 2 equal sides represent the height and 2 equal sides represent the width.

When we subtract the lengths of the 2 sides that represent the height we get a number that we then have to divide by 2 to get the width of the triangle.

Hope this helps. It's a little difficult to explain but the answer is correct :)

The compound inequality would be: 0 <= x <= 5 or x >= 10

From the question, we have the following parameters that can be used in our computation:

no more than 5 totts or more than 10 totts

Represent the variable with s

So, we have the following representation

x no more than 5 totts or x more than 10 totts

As an inequality, we have

0 <= x <= 5 or x >= 10

Answer: 90

Step-by-step explanation:

The number that you need to find because it is missing in the equation is 48.

Let's assume the number we're trying to find is "x."

According to the problem, one-third of the number is (1/3)x, and one-fourth of the number is (1/4)x.

We're told that the sum of one-third of the number and one-fourth of the number is 28, so we can write the equation as follows:

(1/3)x + (1/4)x = 28

To solve this equation, we need to find a common denominator. The least common multiple of 3 and 4 is 12, so we can rewrite the equation as:

(4/12)x + (3/12)x = 28

Combining the fractions, we get:

(7/12)x = 28

To isolate x, we multiply both sides of the equation by the reciprocal of (7/12), which is (12/7):

x = 28(12/7)

Simplifying the right side of the equation, we have:

x = 48

Therefore, the number we're looking for is 48.

The measurement of acute triangle ABC we can find by direct substitution of the labeled measures in the Law of Sines is,

a/ sin a = b/sin b

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sine rule for a triangle ABC is, a/sinA = b/sinB = c/sinC .

In the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.

Side a, with angle A.

Side b, with angle B.

The correct answer is Stratified Random Sampling

Given that,

In a study, the sample is selected by dividing the class into gender-based groups, then choosing 10 men and 10 women.

Researchers split a population into homogeneous subpopulations called strata (plural of stratum) depending on particular traits in a stratified sample (e.g., race, gender identity, location, etc.).

In order to estimate statistical measures for each subpopulation, each stratum is then sampled using a different probability sampling technique, such as cluster sampling or simple random sampling.

When a population's traits are varied and researchers want to make sure that each characteristic is accurately represented in the sample, they rely on stratified sampling. This aids in the study's validity and generalizability while preventing biases in the research process like undercoverage bias.

The standard deviation of x is 3 cars. So the option A is correct.

Suppose that x is the number of cars per minute that pass through a certain intersection, and that x has the Poisson distribution.

If the mean of x is equal to 9 cars, then we have to determine the standard deviation of x.

An indicator of how much variance from the mean there is is the standard deviation, which can be expressed as spread, dispersion, or spread. A "typical" departure from the mean is represented by the standard deviation. As a result of returning to the data set's original units of measure, it is a well-liked measure of variability.

The Mean = 9 cars

Standard Deviation = Square Root of Mean

In ΔJKL using the angle bisector theorem the value for x is obatined as 48.6 units.

What is angle bisector theorem?

The opposite side of a triangle is divided into two pieces by the angle bisector in proportion to the other two sides. If the interior point of a triangle is equally spaced from its two sides, that point will be on the angle bisector of the angle created by the two line segments.

The measurement for line segment JK = 54 units.

The measurement for line segment LK = x units.

The measurement for line segment LM = 36 units.

The measurement for line segment JM = 40 units.

In ΔJKL line segment KM is an angle bisector.

So, according to the angle bisector theorem -

JM / LM = JK / LK

Substitute the values in the equation -

40 / 36 = 54 / x

Simplify to find the value of x -

x = (54 × 36) / 40

x = (27 × 9) / 5

x = 48.6 units

The normal probability plot can reveal information about the population from which the data were drawn. A straight line pattern indicates normality, whereas deviations from the straight line indicate non-normality.

A normal probability plot is a graphical method for determining whether a set of data values is normally distributed. The plot depicts sample data values on the y-axis and theoretical normal deviate values on the x-axis.

If the plotted points follow a roughly straight line, the population is likely to be normally distributed. If the points plotted deviate significantly from a straight line, the population is not normally distributed.

As a result, the shape of the normal probability plot can provide insight into the normality of the population from which the data were drawn. A straight line pattern indicates that the distribution is normal, whereas deviations from the straight line indicate non-normality.

After gathering information from 110 voters, the results of the hypothesis test were used to make a decision on whether to reject or fail to reject the null hypothesis.

Using these axes, we can describe any point in the plane using an ordered pair of numbers.

Well first we have to find the distance from the origin to the point (4,3). Now to do this we use the distance formula. I didn't want to type this out so i found a picture.

Now the origin point is (0,0) So now we have two points we can plug in to find the difference between them. Now the X1 and X2 as well as y1 and y2 are interchangeable within their brackets.

So D= [tex]\sqrt{(4)^{2} } + (3^{2} )[/tex] Which means D= the square root of 25 which is 5. This means the distance from the origin to (4,3) is 5 feet.

so the triangle with the 35° angle is an isosceles, namely a triangle with twin sides stemming from the center of the circle, well, twin sides make twin angles, and since the center of the circle makes a central angle, well, any arc will get its degrees from that.

Answer:

Step-by-step explanation:

You want to solve the triangle with A=35°, B=60°, and c=10.

When two angles and a side are given, the Law of Sines is useful for providing a solution. In order to use it, we need to know an angle and its opposite side. That is, we need angle C.

Using the sum of angles of a triangle, we have ...

  A +B +C = 180°

  C = 180° -A -B = 180° -35° -60° = 85°

Now, we can use ...

  a/sin(A) = b/sin(B) = c/sin(C)

  b = c·sin(B)/sin(C) = 10·sin(60°)/sin(85°) ≈ 8.69

  a = c·sin(A)/sin(C) = 10·sin(35°)/sin(85°) ≈ 5.76
