What is the mean of Geometric 9 and 36?

Snowcat [4.5K]

Answer:

Mean is 18

Step-by-step explanation:

We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. ... And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18

A simple random sample of n measurements from a population is a subset of the population selected in a manner such that which of

Ierofanga [76]

Answer:

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

Step-by-step explanation:

Simple random sampling:

It is a type of probabilistic sampling.
It is an unbiased representation of population.
The probability of selection is equal for every observation.
A sample is taken in such a way that each member has an equal probability of being selected.
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
Thus,the correct interpretation is given by,

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

c) The simplest method of selection is used to create a representative sample.

The statement is false.

There is no pattern or technique used for selection. The selection is purely random.

d) Each subset of the population has an equal chance of being included in the sample.

The statement is false.

Each object of the population has an equal chance of being included in the sample. and not each subset.

e) Every sample of size n from the population has a proportionally weighted chance of being selected.

The given statement is false.

What is the area of the figure?<br><br> 40 ft2<br> 84 ft2<br> 96 ft2<br> can't be determined

mina [271]

Answer:

$A=80\ ft^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=16\ ft$

To find out the height of the triangle Apply the Pythagorean Theorem

$10^2=(16/2)^2+h^2$

solve for h

$100=64+h^2$

$h^2=100-64$

$h^2=36$

$h=6\ ft$

<em>Find the area of triangle</em>

$A=\frac{1}{2}(16)(6)$

$A=48\ ft^2$

step 2

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=16\ ft\\W=2\ ft$

substitute

$A=(16)(2)=32\ ft^2$

step 3

Find the area of the figure

Adds the areas

$A=48+32=80\ ft^2$

artcher [175]

Answer:

C. Nonlinear

General Formulas and Concepts:

<u>Algebra I</u>

Linear - Proportional relationship y = mx + b
Nonlinear - Any graph that has a degree <em>x</em> higher than 1

Step-by-step explanation:

<u>Step 1: Define</u>

y = 6x³ - 13

<u>Step 2: Identify</u>

We see a cubic function. Quadratics, Cubics, Quartics, etc. are all nonlinear equations.
