the spread data is dispersed across the entire range of data.
What is range of data?
In statistics, we must put the given values, set of data, or set of observations in ascending order in order to determine the range. That indicates that you should start by writing the observations from lowest to highest value. The formula must now be used to determine the range of observations. As a result, the range may alternatively be thought of as the distance between the highest and lowest observation. The range of observation is the name given to the outcome. Statistics' range reflects the variety of observations.
When we plot data, we are considering the shape of the data. We plot the data based on the histogram, for example. The data's shape is Shape.
Outliers are different observations from the majority of the observations and are clustered in the center. Spread is the dispersion of the data throughout the entire range.
Hence, the spread data is dispersed across the entire range of data.

What is the measure of angle A in this triangle?
Enter your answer in the box.
m∠A=
The measure of angle A in this triangle is 50°.
How to calculate the angle?It is important to note that a triangle has three sides and the total angle is 180°.
Therefore A = 2x - 10
B = 70
C = x + 30
The angles will be illustrated thus:
2x - 10 + 70 + x + 30 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide
x = 90/3
x = 30
Therefore A will be:
= 2x - 10
= 2(30) - 10
= 60 - 10
= 50°

in a proof what is the reason that justifies this statement: segment bp is congruent to segment bp.
The necessary explanation is that segment BP is congruent to segment BP, which is the common side of both triangles.
Two figures or items are congruent in geometry if they have about the same size, or if one has the same shape and size as its mirror counterpart.
As seen in the illustration, segment BP and segment BP are congruent since segment BP is the common side of both triangles BPS and BPY.
As a result, the necessary explanation seems to be that segment BP is congruent to segment BP and that segment BP is the identical side of both triangles.

It is true that the polynomial is divisible by 6
How to prove the division of the polynomial?From the question, we have the following polynomial that can be used in our computation:
Polynomial = x^3+15x^2+74x+120
Divisor = 6
Rewrite the given parameters as
P(x) = x³ +15x² + 74x + 120
x = -6
Substitute x = -6 in the equation P(x) = x³ +15x² + 74x + 120
P(-6) = (-6)³ +15(-6)² + 74(-6) + 120

x + 57 = 19
x - 57 = 19
x + 19 = 57
x + 19 = -57

By using Binomial Distribution, it can be calculated that -
P(X = 1) = 0.0005
What is Binomial Distribution?
Binomial distribution is a discrete type probability distribution whose probability density function is given by
P(X = x) = [tex]{n \choose x} p^xq^{n - x}[/tex]
Where p is the probability of success and q is the probability of failure
Here, Binomial Distribution of probability is used

The answer of the given question is A rectangular block of mass m has an inertia moment of Bh3/3.
What is moment of inertia?When a body resists having the direction of its rotation along an axis changed by the application of a torque, this resistance is referred to as having moment of inertia. There are four types of axes: internal, external, fixed, and moving. It is possible to calculate the moment of inertia (I), which is always expressed in terms of that axis, by adding the results of multiplying each particle's mass by the square of its distance from the axis within the particular body. Moment of inertia is the same as mass in linear momentum when calculating the angular momentum of a rigid body.

how would the test statistic change for the wilcoxon rank sum test for the crickets data if the largest value in the fed group had actually been 100 hrs?
The assumptions of the two-sample t-test for comparing two population means:
1. The two samples are independent of one another.
2. The two populations have equal variance or spread.
3. The two populations are normally distributed.
The Wilcoxon test is based upon ranking the nA +nB observations of the combined sample. Each observation has a rank: the smallest has rank 1, the 2nd smallest rank 2, and so on. The wilcoxon rank-sum test statistic is the sum of the ranks for observations from one of the samples.
The Wilcoxon signed rank test is a non-paracontinuouse-level test, in contrast to the dependent samples t-test.
Wilcoxon tests have about 95% of the power of a t-test if the data really are normal, and are often far more powerful if the data is not, so just use a Wilcoxon.
The Wilcoxon test may produce misleading results if many measurements are the same value. When many values are the same, their relative ranks are the same, and this has the effect of diluting the test.

Then the percentages of each expenses are applied to find the values, for example, 40% of that is for employee wages, hence:
0.4 x 60,000 = $24,000.
