Answer:
THE CORRECT ANSWER IS B- 73 FEETThe given condition in question will form a right angle triangle
and the length of sides of triangle are given 55ft, 48ft and missing one.
Now using pythagoras theorem,55²+48²= x²
x² = 3025 + 2304
x² = 5329
Taking square root of 5329 will give 73 ft!
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.
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.

find perimeter of each polygon. Assume that the lines which appear to be tangent are tangent. Part 1. NO LINKS OF ANY KIND.
9514 1404 393
Answer:
7) 57.8
8) 73.8
Step-by-step explanation:
The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.
7) P = 2(22.2 +6.7) = 57.8
8) P = 2(22.9 +14) = 73.8

ΔDEF and ΔJKL are congruent to each other.
TriangleTriangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Right angle triangleIt 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 findΔDEF 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.

Answer:
(a) x=45°
(b) If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Step-by-step explanation:
(a)
Angles in a quadrilateral add to 360:
<A+<B+<C+<D=360
2x+90+x+3x=360
6x=270
x=45°
(b)
If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Answer: Step-by-step explanation:
3x+2x+x=360-90
6x=270
x=45
∠DAB=2x=90° and ∠ABC=90° ⇒ AD║BC

-5(x-5)=2(-4x+5) find x step by step please
Answer: -5
Step-by-step explanation:
-5(x-5)=2(-4x+5)
-5x + 25 = -8x +10
3x +25 = 10 (add 8 from both sides)
3x = -15 (subtract 25 from both sides)
x = -5 (divide 3 from both sides)
