What is the value of 8 power 8?
Answer:16,777,216
Step-by-step explanation:
Find A. Round to the nearest tenth.
Answer:
27.8 degrees
Step-by-step explanation:
Wasn't it 'a,' not 'A,' that you wanted?
The ratio a/ 30 is the cosine of the angle 22 degrees, which in turn is 0.927:
a
Then 0.927 = ------- which yields a = 30(0.927) = 27.8 degrees

Audrey and Billy are as far as 367 meters apart.
What is displacement of an object?The displacement of an object is its distance covered or moved in a specific direction. Displacement is an example of vector quantity.
A vector quantity is generally any type of quantity which can be expressed in magnitude and direction. Some examples include: weight, displacement, acceleration, force, etc.
Since Audrey walked 285 meters west and Billy walked 213 meters south from the same starting location, then we can determined the distance far apart by applying the Pythagorean theorem.
So that,
/hyp/^2 = /opp/^2 + /adj/^2
Let their distance apart be represented by s,
s^2 = 231^2 + 285^2
= 53561 + 81225
s = (134586)^1/2
s = 366.86

Probability samples are advantageous to the researcher because: A. they are perfectly representative of the population from which they are drawn. B. the method by which they are selected limits conscious and unconscious sampling bias. C. the method by which they are selected limits conscious and unconscious bias and the accuracy/representativeness of the sample can be estimated. D. they allow the researcher maximum exibility in the creation of samples. E. the accuracy/representativeness of the sample can be estimated.
Answer:
C. the method by which they are selected limits conscious and unconscious bias and the accuracy/representativeness of the sample can be estimated.
Step-by-step explanation:
The probability sampling technique allows for each element in the sample to be representative of the population data from which the samples are drawn. This sort of sampling technique helps to randomize and eliminate errors which might creep into measurement. Since the researcher has the knowledge of the population data or distribution, he takes advantage of these in the allocation of samples using the probabilities of each Sample.

What is the 3 triangular number?
A triangular number succession is the representation of numbers as just an ordered set of equilateral triangles. The order of these numbers is 1, 3, and 6.
What exactly is meant by triangular numbers?A triangular number is one that may be written as the sum of a initial n positive integers.
A good example of a triangular number is 6, which may be written as 1+2+3 when the first three positive integers are added together.Triangular numbers make up a sequence if one considers the sum of the first positive integer as the initial element, the sum of the first two positive integers as the second element, and so on.If a number equals that sum of such initial n positive integers, then n denotes the position of that particular triangular number with in the series.Triangular numbers can be used to create equilateral triangles.The first 3 triangular numbers are therefore 1, 3, and 6.

I think that it is 56
1/4 Ib = ? oz
I don’t understand how the fraction can be turned into the answer , I know you have to multiply or divide but I just do not understand this question
Answer: 1/4 pound (lb) is equal to 4 ounces (oz).
This is because there are 16 ounces in one pound, so you can divide a pound into 16 equal parts, and each part is one ounce. Similarly, you can divide a pound into 4 equal parts , and each part is 1/4 pound. So in order to convert 1/4 pound to ounces, you can multiply 1/4 by 16.
1/4 lb * 16 oz/lb = 4 oz
When converting units, you are essentially multiplying or dividing by a conversion factor. In this case, the conversion factor is 16 oz/lb which tells you that there are 16 ounces in one pound. This factor allows you to convert between pounds and ounces by multiplying or dividing by it.
It's important to pay attention to the units in the conversion factor when using them. Here, the numerator and denominator of the conversion factor have the same unit, but it's not always the case. And the conversion factor helps to cancel out the unwanted unit and yield the desired unit in the end.

Find the measure of an interior angle of a regular hexagon
Therefore , the solution of the given problem of angles comes out to be
Each inner angle of a regular hexagon measures 120 degrees.
Exactly what angles are there?Two rays that converging at the vertex, or center, of an angular structure in geometry make up the structure. We refer to these rays as the faces of the angle. Two beams may well be able to create any angle within just a planar depending on their location. Additionally, an angle is created when two planes intersect. .
Given: A standard hexagon
Measure each internal angle of a standard hexagon.
Solution:
(n - 2) x 180° is the formula for the sum of lengths of a polygon's inner angles.
Every side of a regular polygon is the same length, and every angle is the same size.
A hexagon has six sides.
Find the total of the measurements of the internal angles of a hexagon by substituting n = 6 in (n - 2) x 180n latitude in step 1.
=> (n - 2) * 180°
=> (6 - 2) * 180°
=>4 * 180°
=> 720°
Step 2: Since a regular hexagon has six sides and all of its sides and angles are equal in size, divide by six to obtain the dimensions of each inner angle.
=> 720° /6
=> 120°
Each internal angle of such a regular polygon is 120 degrees in length.

A sample of size 95 will be drawn from a population with mean 25 and standard deviation 13. Find the probability that will be between 22 and 27.
1.3338 is the likelihood, The probability of anything occurring is known as probability.
How are probabilities calculated?The probability of anything occurring is known as probability. To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur.
The likelihood or chance that a specific event will occur is represented by a probability. Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.
Explanation:
Mean (m) = 25
The standard deviation is 13
Sample size (n) is 95.
Chance that x will fall between 22 and 27.
Zscore = x - mean / s / n
If x = 22, Zscore is equal to (22 - 25) / (13/95).
For x = 27, Zscore is equal to (27 - 25) / (13/95) / n = 13 / 95, which is 1.3338.
1.3338 is the likelihood.
