Answer:

The mean of the sampling distribution of sample means would be of 23.4 pounds.

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.

What would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the population mean, that is, of 23.4 pounds.

Answer:

Option (1)

Step-by-step explanation:

By the inscribed angle theorem inside a circle,

"Measure of an inscribed angle is half the measure of the intercepted arc"

[tex]\frac{1}{2}[/tex][m(arc AB)] = m(∠ABC)

m(arc AB) = 2[m(∠ABC)]

x = 2(41°)

x = 82°

Option (1) is the correct option.

Subtraction of perfect squares:

The factors of a subtraction of perfect squares is given by:

[tex]a^2 - b^2 = (a-b)(a+b)[/tex]

What are the factors of x² - 81?

This can be written as:

[tex]x^2 - 81 = (x)^2 - (9)^2[/tex]

So

[tex](x)^2 - (9)^2 = (x - 9)(x+9)[/tex]

Answer:

11 / 16

Step-by-step explanation:

5/16 + 6/16

5 + 6 = 11

Denominator stays the same (16)

11 / 16

Answer:

4.5/16+6/16=4.5+6/16

=10.5/16

Step-by-step explanation:

Here you can see denominator in both the side are same and operation sign between them is plus, therefore you can take denominator as is it.

Then add numerator and divide by denominator which is 16. Answer is 10.5/16 since you have to simplify only.

Answer:

180 square inches

Step-by-step explanation:

First off since the square will be easiest to do

a=a^2

a=6^2

a=36

now for the triangles

a= height of triangle * base/ 2

a= 12*6/2

a= 36

and since there is 4 of the triangles we multiply 36 by 4

=144

now we add 144 to 36 and we have the total

Answer:

He will charge $28.

Step-by-step explanation:

We know that Jamal charges $3.50 per square yard.

Now we need to find the area in the image, it may be kinda hard to see it, but we can think of the image as a rectangle of 4yd by 3yd where we subtracted the area of a square of side length equal to 2yd.

The area of the rectangle is:

A = 4yd*3yd = 12 yd^2

And the area of the square is:

a = (2yd)^2 = 4 yd^2

The area of our image (equal to the difference between the area of the rectangle and the area of the square) is:

Area = A - a = 12 yd^2 - 4 yd^2 = 8 yd^2

Area = 8 yd^2

And he charges $3.50 per square yard, then for 8 square yards he charges 8 times that amount, which is:

C = 8*$3.50 = $28

The function representing the number of bacteria present each day is

[tex]\rm f(t) = 2032(0.85)^{t}[/tex] .

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

The set X is called the domain of the function and the set Y is called the codomain of the function

A bacteria population starts at 2032 and decrease by 15% everyday.

a function representing the number of bacteria present each day

[tex]\rm f(t) = 2032(1-.15)^{t}[/tex]

[tex]\rm f(t) = 2032(0.85)^{t}[/tex]

Therefore [tex]\rm f(t) = 2032(0.85)^{t}[/tex] is the correct answer .

I'm backkkk!

40 = 5 (w - 2)            would be the equation.

40 = 5w - 10              using the distributive property.

+ 10        + 10             because you must add to both sides to get rid of the 10.

50 = 5w

/5      /5                      again, keep the same on both sides, and...

10 = w

The absolute Error is 5.66%.

The discrepancy between a quantity's measured or inferred value and its actual value is known as the absolute error.

The absolute error is insufficient because it provides no information about the significance of the error. An inaccuracy of a few centimetres when estimating the kilometres between cities is insignificant and unimportant. A measurement mistake of a few centimetres when measuring tiny machine parts is a highly important defect. Although both inaccuracies are in the centimetre range, the second one is more serious than the first.

Given:

Actual Mass = 53g

and, Measure mass= 56 g

So, Absolute Error = | 56- 53 / 56| x 100

Absolute Error = |3 / 56| x 100

Absolute Error = 0.056603 x 100

Absolute Error = 5.66%

Hence, the absolute Error is 5.66%.
