Using the p-value rule, if a null hypothesis is rejected at a significance level of 0.01, it will ________ be rejected at a sign

ificance level of 0.05
Mathematics

Answer:

<u>always</u>

Step-by-step explanation:

For this hypothesis test:

<u>The Decision rule: </u> To reject the null hypothesis H_o if the p-value is lesser than < the significance level.

At the level of significance 0.01, the null hypothesis is rejected.

So, p-value < 0.01 and this typically shows that p-value is < 0.05.

Therefore, it will <u>always</u> be rejected at ∝ = 0.05

Janelle drew KL in isosceles trapezoid FGHJ to create similar trapezoids FKLJ and KGHL. Based on the given information, what are
Tems11 [23]

Answer:

w = 36 centimeters

y = 24 centimeters

Step-by-step explanation:

The exact question is as follows :

Given - Janelle drew KL in isosceles trapezoid FGHJ to create similar trapezoids FKLJ and KGHL.

To find - Based on the given information, what are the values of y and w in centimeters?

Solution -

We can see that from the diagram,

Trapezoid FKLJ is 3 times bigger than Trapezoid KGHL

So,

The side KL = 3 times side GH

⇒12 = 3×4

⇒12 = 12 centimeters

So,

side FJ = 3 times side KL

⇒w = 3×12

⇒w = 36 centimeters

Now,

The side KF = 3 times side KG

⇒KF = 3×8

⇒KF = 24

Now,

We know,

In  isosceles trapezoid  two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length

So,

Side LJ = side KF

⇒y = 24 centimeters

∴ we get

w = 36 centimeters

y = 24 centimeters

Find the distance from point A(−1, 7) to the line y=3x. Round your answer to the nearest tenth.
bearhunter [10]

Answer:

<em>The distance from the point to the line is approximately 3.2 units</em>

Step-by-step explanation:

<u>Distance From a Point to a Line</u>

Is the shortest distance from a given point to any point on an infinite straight line. The shortest distance occurs when the segment from the point and the line are perpendiculars.

If the line is given by the equation ax + by + c = 0, where a, b and c are real constants, the distance from the line to a point (x0,y0) is

\displaystyle d= \frac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}

The line is given by the equation:

y=3x. We need to transform it into the specified form.

Subtracting 3x:

y - 3x = 0

Comparing with the general form of the line, we have

a=-3, b=1, c=0

The point (xo,yo) is (-1,7), thus:

\displaystyle d= \frac{|-3\cdot (-1)+1\cdot 7+0|}{\sqrt{(-3)^2+1^2}}

\displaystyle d= \frac{|3+7|}{\sqrt{9+1}}

\displaystyle d= \frac{|10|}{\sqrt{10}}

\displaystyle d= \frac{10}{\sqrt{10}}

d\approx 3.2

The distance from the point to the line is approximately 3.2 units

If AB = BC = CA, what is m1?
Alborosie

Answer:

60°

Step-by-step explanation:

All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:

180/3 = 60

60° is your answer.
