The sampling distribution of a statistic is (select the best answer): The mechanism that determines whether the random sampling

was effective. A normal curve, for which probabilities are obtained by standardizing. A distribution of all parameters from the population that is to be randomly sampled. A distribution of a single statistic from repeated random samples of the same size, from the same population. A distribution of all possible summary statistics from a single random sample, from the same population.

Answer:

A normal curve, for which probabilities are obtained by standardizing.

Step-by-step explanation:

The sampling distribution of a statistic :

By statistic we mean the characteristic of a sample.  It may be sample mean, sample variance, sample std deviation, and so on.

By central limit theorem we have the mean of all samples taken at random from a population follow a normal distribution irrespective of the original distribution.  Here we collect so many samples and find the statistic for all samples and find the distribution.

Hence the correct option is

A normal curve, for which probabilities are obtained by standardizing.

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of S
Talja [164]

Answer:

c) 10 units

The length of side RT of the polygon  RT = 10

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given the coordinates of vertices R and T

R( -7 ,3) and T (3 ,3)

we have to find the length of side RT

We will use distance formula

RT  = \sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }

<u><em>Step(ii):-</em></u>

RT  = \sqrt{(3-3)^{2} +(3-(-7))^{2} }

RT  = \sqrt{0+(10)^{2} }

RT = √100

RT = 10

The length of side RT of the polygon  RT = 10

Concept of place value, ordering and rounding (in small and easy words) ​
Setler [38]

Answer:

Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens,When rounding an integer, all place values to the right of the rounding position are filled with zeros. For example, let's round 8,372 to the hundreds position, which currently contains the number 3. Because the number following the 3 is a 7, we raise the 3 to a 4, and the answer is 8,400.

Find the 10th term of the geometric sequence 8, -24, 72, ...
solniwko [45]

Answer:

-157464

Step-by-step explanation:

Geometric Sequence formula = ar^n-1

In the above formula,

a = the first term

r = common differnce

n = the term which we want to know

So, the first term is 8.

We can tell that these numbers have a common difference of -3.

We need to find the 10th term.

=> 8*(-3^10-1)

=>8*-3^9

=>8*-19683

=>-157464

What’s the answer to this and working out
fiasKO [112]

Answer:   \bold{\dfrac{81}{4t^2u^{20}}}

<u>Step-by-step explanation:</u>

\bigg[\dfrac{4\cdot t^{-1}\cdot u^6}{18\cdot t^{-2}\cdot u^{-4}}\bigg]^{-2}\\\\\\\text{simplify 4 and 18 by dividing each by 2:}\\\bigg[\dfrac{2\cdot t^{-1}\cdot u^6}{9\cdot t^{-2}\cdot u^{-4}}\bigg]^{-2}\\\\\text{distribute the exponent using the power rule (multiply the exponents):}\\\dfrac{2^{-2}\cdot t^{2}\cdot u^{-12}}{9^{-2}\cdot t^{4}\cdot u^{8}}

\text{Move the terms with negative exponents to the other side of the fraction}\\\text{bar and change the sign of the exponents:}\\\dfrac{9^2\cdot t^2}{2^2\cdot t^4\cdot u^8\cdot u^{12}}\\\\\\\text{Simplify using the multiplication rule for exponents (add the exponents)}\\\text{and the division rule of exponents (subtract the exponents):}\\\dfrac{81}{4\cdot t^{4-2}\cdot u^{8+12}}\\\\\\\text{Simplify:}\quad \dfrac{81}{4\cdot t^{2}\cdot u^{20}}
