At 85% confidence interval, the margin of error is 1.44 when the distribution of this population is approximately normal and has a standard deviation of $9,166.

The margin of error is a statistic that describes how much random sampling error there is in survey results. One should have less faith that a poll's findings would accurately reflect those of a population census the higher the margin of error. In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings.

Given,

Starting salaries of 150 college graduates who have taken a statistics course have a mean of $42,991. Suppose the distribution of this population is approximately normal and has a standard deviation of $9,166.

Margin of error:

At 85% confidence level

α = 1 - 85%

If other factors are held constant, sets of data that would produce the largest value for an independent-measures t statistic is the two samples both have n =30, with sample variances of 20 and 25

In a T test, the T statistic is used to help you decide whether to accept or reject the null hypothesis.

You utilize it in a manner that is quite similar to using a Z-score. When you don't know the population standard deviation or have a limited sample size, you use the t statistic.

You employ the T statistic with a p value while performing a hypothesis test. Your results' likelihood of being the result of chance is indicated by the p-value. Typically, in statistics, you use a T Test with a T Statistic rather than a Z score because you don't know much about the population.

To have larger t value , Combined standard deviation should be less

Therefore, n should be large and standard deviation should be less

Hence , The two samples both have n=30, with sample variances of 20 and 25 will provide us larger t-statistics

An equilateral triangle in geometry is a triangle with equal-length sides on all three sides. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60° and congruent with the others.

The length each side of △ABC is 9 units.

Thus it is an equilateral triangle. The measurement of each angle is 60°.

Given that,  ∠ABC = 4x°.

Therefore, 4x° = 60°

Divide both sides by 4:

x = 15

The sum of all three angles of a triangle is 180°.

∠MNL + ∠MLN + ∠NML = 180°

Since no figure is given in the question we employ the reflexive characteristic to demonstrate that the overlapping sections are congruent in order to demonstrate that overlapping triangles are congruent.

If two triangles are precisely the same size and shape—that is, if they have the same side lengths and angle measurements—they are said to be congruent. If we are aware that two triangles have all the same sides and angles, we can conclude that the triangles are congruent.

To demonstrate that two triangles are congruent, however, we don't necessarily need to know that all of their sides and angles are congruent.

The value of h is 70/17 if they are similar triangles and two sides are given in the figure.

Three edges and three vertices make up a triangle, which is a polygon.

In Euclidean geometry, any three points that are not collinear identify a distinct triangle and a distinct plane at the same time (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and that triangle is contained in just one plane. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however in higher-dimensional Euclidean spaces, this is no longer the case. Except as specifically stated, this article is about triangles in the Euclidean plane and general Euclidean geometry.

The figure has two similar triangles.

What is an equilateral triangle?

In geometry, an equilateral triangle is a triangle whose all three sides are of equal length. The sides of an equilateral triangle are congruent, which means that all sides are of equal length. All the interior angles are equal(60 degrees) too.

The property of an equilateral triangle says that "All sides are equal in lengths".

So by using the above property, we can make the equation as

    3x - 6 = 2x + 3

This simplifies to:

3x = 2x + 9

Then, you can subtract 2x from both sides to get rid of the 2x on the left-hand side:

3x - 2x = 2x + 9 - 2x

This simplifies to:

x = 9

Now find BC as

BC = 2x + 3

    = 2(9) + 3

     = 21

Hence, the length of the side BC is 21 units.

The real number solution set for the trigonometric equation is x = 2πn + π/6 or 2πn + 5π/6 where n = is an integer

A trigonometric equation is an equation that contains the trigonometric ratios.

Given the trigonometric equation

√(sin²x - 4sinx + 4) + √(sin²x + 4sinx + 4) = √(sin²x + 7sinx + 12.25)

We know that sin²x - 4sinx + 4 = (sinx - 2)².

Also, sin²x + 4sinx + 4 = (sinx + 2)².

Also, sin²x + 7sinx + 12.25 = (sinx + 3.5)².

So, substituting these into the equation, we have that

√(sin²x - 4sinx + 4) + √(sin²x + 4sinx + 4) = √(sin²x + 7sinx + 12.25)

√(sinx - 2)² + √(sinx + 2)² = √(sinx + 3.5)²

|sinx - 2| + |sinx + 2| = |sinx + 3.5|

(2 - sinx) + (sinx + 2) = (sinx + 3.5)

2 - sinx + sinx + 2 = sinx + 3.5

Colecting like terms, we have that

-sinx + sinx + 2 + 2 = sinx + 3.5

0 + 4 = sinx + 3.5

4 = sinx + 3.5

Subtracting 3.5 from both sides, we have that

sinx = 4 - 3.5

sinx = 0.5

Taking inverse sin, we have that

x = sin⁻¹(0.5)
