Answers

Answer:

Step-by-step explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer:

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.

ΔDEF and ΔJKL are congruent to each other.

Triangle

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Right angle triangle

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Given

DF = JL = a, FE = LK = b,

And ΔDEF is a right triangle.

To find

ΔDEF and ΔJKL are congruent to each other.

How to find the ΔDEF and ΔJKL are congruent to each other?

Since the Pythagoras theorem is applicable in ΔDEF.

a² + b² = c²

This equation also satisfies the ΔJKL Hence angle K is the right-angle.

Since, ∠F = ∠L = 90°,

DF = JL = a,

FE = LK = b

Therefore, ΔDEF ≅ ΔJKL

Thus, ΔDEF and ΔJKL are congruent to each other.

The right triangle has a perimeter of 40 centimeters.help pls

Answers

Answer:

Step-by-step explanation:

P= side 1+ side 2 + side 3

40-(17+8)=15

15x8/2=60

Area of triangle, who has perimeter of 40 centimeters is 60 cm².

What is Area of Triangle?

Area of a Triangle = A = ½ (b × h) square units

where b and h are the base and height of the triangle, respectively.

Given: Perimeter= 40cm

Now, 17+8+side=40

side= 40-25

side= 15 cm

Now, Area of triangle,

=1/2*b*h

= 0.5*15*8

= 60 cm²

Hence, Area of triangle= 60 cm².

In Test A, suppose you make 100 experimental measurements of some quantity and then calculate mean, standard deviation, and standard error of the numbers you obtain. In Test B, suppose you make 1000 experimental measurements of the same quantity and you again calculate mean, standard deviation, and standard error.
How would you expect the mean, standard deviation, and standard errors found in Test A and Test B to compare? (You can use the Excel simulation and change the "Number of Experiments" parameter to investigate this yourself.
A.) I would expect the means, the standard deviations, and the standard errors in Test A and Test B to be about the same.
B.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be smaller than in Test A
C.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be bigger than in Test A
D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.
E.) would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be larger than in Test A.

Answers

Answer:

D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

By the Central Limit Theorem:

Both tests, A and B, are of the same quantity, so they have the same mean and standard deviation. However, since the standard error is inversely proportional to the sample size, and test B has a greater sample size than test A, the standard error in test B should be lower, and thus, the correct answer is given by option D.
