Answer:

sampling distribution = 22.4

sampling deviation = 0.68

Step-by-step explanation:

Given that :

Mean , μ = 22.4

Standard deviation, σ = 5.8

n = 73

Therefore, the sampling distribution of the mean and the standard deviation is

[tex]$\mu_{\overline x} = 22.4$[/tex]

So, [tex]$\sigma_{\overline x}=\frac{\sigma}{\sqrt n}$[/tex]

            [tex]$=\frac{5.8}{\sqrt {73}}$[/tex]

          = 0.68

So the sampling distribution of the mean is 22.4

The standard deviation is 0.68

Answer:

(x-6)(x+6)

Step-by-step explanation:

Answer:

Not sure what the question is but the equation would be

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]28^{2} = 20^{2} + b^{2}[/tex]

and to find the missing side

784 = 400 + [tex]b^{2}[/tex]

b= 19.6

The missing side would be 19.6

Answer:

19.6

Step-by-step explanation:

u see this is how the Pythagorean theorem works a^2 + b^2 = c^ i hope this helps have a great day bye please mark as brainliest :D

Answer:

C) [tex]\sqrt{90}[/tex]

Step-by-step explanation:

VY = base and leg

XY = height and leg

VX = hypotenuse (c)

VY:

9 - 6 = 3

Solving for VX(c):

a² + b² = c²

3² + 9² = c²

9 + 81 = c²

c² = 90

c = [tex]\sqrt{90}[/tex]

Answer:The answer would be C 90

RM 4.05

Step-by-step explanation:

6mnts=70% of 500 is 350, so 150

1 year= 70% of 150 is 105, so 45

1 n half year = 70% of 45 is 31.5, so 13.5

2 years = 70% of 13.5 is 9.45, so Rm 4.05

Answer: The answer is "tween".

Step-by-step explanation: One of the first usages of the term "tweens" was in the late 1990s referring to children who are in the liminal space between childhood and adolescence. In other words, these children are in a state of “in between.” The culture of tweens originally emerged as a marketing niche directed at preteen girls.

Step-by-step explanation:

30 multiplied by 1.34 is 40.2

The stone will hit the ground after 3.5 seconds.

Given information:

A stone is dropped from a 196-foot platform.

The height of the stone after t seconds is represented by [tex]h=-16t^2+v_0t+196[/tex]

As the stone hits the ground, the height will become zero and the initial velocity [tex]v_0[/tex] is equal to zero as it is dropped.

So, the time after which the stone will hit the ground will be calculated as,

[tex]h=-16t^2+v_0t+196\\0=-16t^2+0t+196\\16t^2=196\\t^2=12.25\\t=3.5[/tex]

Therefore, the stone will hit the ground after 3.5 seconds.

Answer:

170 in^2

Step-by-step explanation:

you have to find the area of each surface of the square

1) the square on the right side:

5x5=25 in^2

there are 2 of these on opposite sides

2)the of the rectangle facing us;

6x5=30in^2  (5 because 5 is the height)

there are 4 of these

Answer:

0.62

Step-by-step explanation:

Answer:

Part A;  n= 196

Part B:  n = 120

Part C:

d. No, a sample of students at the nearest college is a convenience sample, not a simple random sample. so it is very possible that the results would not be representative of the population of adults.

Step-by-step explanation:

Part A;

The sample size n can be calculated by using the formula

p^ ± z∝/2* √pq/n

this implies that

e= z∝/2* √pq/n

where e= ║p-p^║= 0.07

p^= 0.5

q^= 0.5

Putting the values

e= z∝/2* √pq/n

0.07= ± 1.96 √0.5*0.5/n

Squaring both sides

0.0049 = 3.8146*0.25/n

n= 196

Part B:

Given p^= 0.81  and q^= 1-p^= 1-0.81= 0.19

e= 0.07

Using the formula

e= z∝/2* √pq/n

Putting the values

0.07= ± 1.96 √0.81*0.19/n

Squaring both sides

0.0049 = 3.8146*0.1539/n

n= 119.809= 120

Part C:

The sample selected is not a random sample because all the adults who have heard about the brand do not have equal chances of being chosen.

It is convenience sample that is it is chosen at ease from a nearby college.

Answer:

Factorize, then divide the common factors.

Step-by-step explanation:

A rational expression is one that involves the division of two polynomials. The two polynomial having the same variable in each expression.

To simplify a rational expression, the first thing to do is to factorize each expression. This would ensure that there exist a common factor between the numerator and denominator.

Then you can divide by the common factor.

The remaining expressions in the quotient would have been reduced to their simplest form.

Answer: sorry about that Evaluate for y=8

9x+(4)(8)

9x+(4)(8)

=9x+32

Hope this help :D

Answer:

It doesn't say what x is so once you have x all you have to do is insert the numbers in their place, so you will get 9(x) + 4(8). Now multiply 9 by x, then multiply 4 and 8, which is 32. Now add 32 and whatever 9 times x is. Hope this helps!

Answer:

the answer is 708.75

Step-by-step explanation:

Answer:

A. “However, notwithstanding all that has been done and written against it, that brutish barbarity, and unparalelled injustice, is still carried on to a very great extent in the colonies, and with an avidity as insidious, cruel and oppressive as ever.”

Explanation:

Ottobah Cugoano's "Thoughts and Sentiments on the Evil of Slavery" provides a personal take on the issue of slavery and how evil of a practice it is for African Americans. At the same time, he also asserted that slaves had the right to rebel against their masters for the treatment they were put under.

One explicit statement that reveals the author's beliefs about the slavery system is "However, notwithstanding all that has been done and written against it, that brutish barbarity, and unparalelled injustice, is still carried on to a very great extent in the colonies, and with an avidity as insidious, cruel and oppressive as ever." Through these lines, Cugoano labels slavery as "brutish barbarity, and an unparallelled injustice ... insidious, cruel and oppressive..."

Thus, the correct answer is option A.

The answer would be : -2,4

Answer:

<1 = <3

m<1 + m<4 = 180

m 2 + m 3 = 180​

Step-by-step explanation:

If <1 and <2 are linear pair, hence <1 + <2 = 180

If <2 and <3 are linear pair, hence <2 + <3 = 180

Since <1, <2 and <3 are linear pair, hence <1 and <3 vertically opposite

<1 and <4 will also be a linear pair since they will lie on the same straight line. Since the sum of angle on a straight line is 180, hence <1 + <4  = 180degrees

The correct options are

<1 = <3

m<1 + m<4 = 180

m 2 + m 3 = 180​
