From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is

Answers

Answer 1

Answer:

The standard error of the mean = 2

Step-by-step explanation:

Given that:

The standard deviation σ = 14

The sample size n = 49

The sample mean [tex]\overline x[/tex] = 56

The formula for calculating the standard error can be expressed as:

[tex]S.E = \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]S.E = \dfrac{14}{\sqrt{49}}[/tex]

[tex]S.E = \dfrac{14}{7}[/tex]

S.E = 2

Therefore, the standard error of the mean = 2

Ella is going to drive from her house to city a without stopping. Ella’s house is 100 miles from city a and after driving three hours she will be 25 miles away from city a. Writing equation for D in terms of T represent an LS distance from city a T hours

Answers

Answer:
d = 100 - 25t

Step-by-step explanation:

Let's use basic logic here.
If we are 100 miles away from a place, and we've got 25 miles to go, we've already travelled 75 miles.
Since we've travelled 75 miles in 3 hours, then we travel at a rate of 75 divided by 3 = 25 miles per hour.

The distance to City A will be represented as 100 - miles already travelled. We can find how many miles have been travelled by multiplying 25 by t, the amount of hours we've spent driving.

This creates the equation d = 100 - 25t

Find the value of x in the figure below.
(8x + 5)°
(13x – 14)°

Answers

Answer:

x = 9

Step-by-step explanation:

The question is shown in the attached figure.

We can see that, (8x + 5)°  and (13x – 14)° forms a linear pair. It would mean that,

(8x + 5)° + (13x – 14)° = 180°

21x-9 = 180°

21x = 180° + 9

21x = 189

x = 9

Hence, the value of x is 9.

1,a) Find a recursive formula for the sequence 1, 2, 6, 24, 120, . . . .

b) Find the sixth and the seventh terms of the sequence.

Answers

a) The n-th term in the sequence is the product of the first n natural numbers:

1 • 2 = 2

1 • 2 • 3 = 6

1 • 2 • 3 • 4 = 25

1 • 2 • 3 • 4 • 5 = 120

and so on. Recursively, the n-th term is a function of the (n - 1)-th term as

a(n) = n a(n - 1)

b) Using the rule above, the 6th and 7th terms are

a (6) = 6 a (5) = 6 • 120 = 720

and

a (7) = 7 a (6) = 7 • 720 = 5040

We want to find a recursive formula for the given sequence and then find the next terms in the given sequence.

the solutions are:

a) Aₙ = n*Aₙ₋₁

b) A₆ = 720 and A₇ = 5,040

We start with the sequence:

1, 2, 6, 24, 120, ...

a) Let's find the recursive formula.

If Aₙ represents the n-th term in the sequence, then we have:

A₁ = 1

A₂ = 2 = 2*1 = 2*A₁

A₃ = 6 = 3*2 = 3*A₂

A₄ = 24 = 4*6 = 4*Aₐ

A₅ = 120 = 5*24 = 5*A₄

So we can see the pattern, the recursive formula is just:

Aₙ = n*Aₙ₋₁

b) We want to find the sixth and the seventh terms of the sequence, we can use the recursive formula we got above.

A₆ = 6*A₅ = 6*120 = 720

A₇ = 7*A₆ = 7*720 = 5,040

The sixth term is 720 and the seventh term is 5,040

The midpoint of AB is M(4, -2). One endpoint is A(-2, 6). What is the other endpoint for B?

Answers

Answer:

endpoint for B is (10,-2)

Step-by-step explanation:

M={(x1+x2)/2,(y1+y2)/2}

(4,2)={-2+x2/2,6+y2/2)

By equating the x coordinates

4=-2+x2/2

8=-2+x2

8+2=x2

x2=10

By equating the y coordinates

2=6+y2/2

4=6+y2

4-6=y2

y2=-2

Therefore the endpoint for B is (10,-2)

A satellite flies 118404 miles in 15.18 hours. How long would it take to fly 174798 miles?

Answers

Answer:

22.41 hours

Step-by-step explanation:

Set up a proportion where x is the time to fly 174798 miles

[tex]\frac{118404}{15.18}[/tex] = [tex]\frac{174798}{x}[/tex]

Cross multiply and solve for x:

118404x = 2653433.64

x = 22.41

So, it would take 22.41 hours to fly 174798 miles

Will mark brainliest from Where I Lived, and What I Lived For in Waldenby Henry David ThoreauLook at a meeting-house, or a court-house, or a jail, or a shop, or a dwelling-house, and say what that thing really is before a true gaze, and they would all go to pieces in your account of them. Men esteem truth remote, in the outskirts of the system, behind the farthest star, before Adam and after the last man. In eternity there is indeed something true and sublime. But all these times and places and occasions are now and here. God himself culminates in the present moment, and will never be more divine in the lapse of all the ages. And we are enabled to apprehend at all what is sublime and noble only by the perpetual instilling and drenching of the reality that surrounds us. The universe constantly and obediently answers to our conceptions; whether we travel fast or slow, the track is laid for us. Let us spend our lives in conceiving then. The poet or the artist never yet had so fair and noble a design but some of his posterity at least could accomplish it.Let us spend one day as deliberately as Nature, and not be thrown off the track by every nutshell and mosquitos wing that falls on the rails. Let us rise early and fast, or break fast, gently and without perturbation; let company come and let company go, let the bells ring and the children crydetermined to make a day of it. Why should we knock under and go with the stream? Let us not be upset and overwhelmed in that terrible rapid and whirlpool called a dinner, situated in the meridian shallows. Weather this danger and you are safe, for the rest of the way is down hill. With unrelaxed nerves, with morning vigor, sail by it, looking another way, tied to the mast like Ulysses. If the engine whistles, let it whistle till it is hoarse for its pains. If the bell rings, why should we run? We will consider what kind of music they are like. Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance, that alluvion which covers the globe, through Paris and London, through New York and Boston and Concord, through Church and State, through poetry and philosophy and religion, till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake; and then begin, having a point d'appui, below freshet and frost and fire, a place where you might found a wall or a state, or set a lamp-post safely, or perhaps a gauge, not a Nilometer, but a Realometer, that future ages might know how deep a freshet of shams and appearances had gathered from time to time. If you stand right fronting and face to face to a fact, you will see the sun glimmer on both its surfaces, as if it were a cimeter, and feel its sweet edge dividing you through the heart and marrow, and so you will happily conclude your mortal career. Be it life or death, we crave only reality. If we are really dying, let us hear the rattle in our throats and feel cold in the extremities; if we are alive, let us go about our business.Time is but the stream I go a-fishing in. I drink at it; but while I drink I see the sandy bottom and detect how shallow it is. Its thin current slides away, but eternity remains. I would drink deeper; fish in the sky, whose bottom is pebbly with stars. I cannot count one. I know not the first letter of the alphabet. I have always been regretting that I was not as wise as the day I was born. The intellect is a cleaver; it discerns and rifts its way into the secret of things. I do not wish to be any more busy with my hands than is necessary. My head is hands and feet. I feel all my best faculties concentrated in it. My instinct tells me that my head is an organ for burrowing, as some creatures use their snout and fore paws, and with it I would mine and burrow my way through these hills. I think that the richest vein is somewhere hereabouts; so by the divining-rod and thin rising vapors I judge; and here I will begin to mine.The speakers primary purpose in this passage is toA.criticize the fast-paced nature of society B.explain his relationship with GodC.promote awareness of the natural worldD.encourage the audience to find reality in the momentE.describe his daily pursuits Let the random variable Q represent the number of students who go to a certain teacher's office hour each day.
