Paul wants to estimate the mean number of siblings for each student in his school. He records the number of siblings for each of 100 randomly selected students in the school. What is the parameter?

Answers

Answer 1

Answer:

A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.

In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.

For example, in a table:

#student        #siblings.

     1                       3

     2                       1

     3                        4

      ...                       ...

In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.

A building casts a shadow 47 feet long. At the same time, a 38‐foot‐tall flagpole casts a shadow 9.4 feet long. What is the height of the building?

Answers

210 feet  To answer this question you need to know the ratio of shadow with the actual object. In this case, 42 feet flagpole cast 9.4 feet shadow. Then the ratio is:

42feet/9.4 feet= 4.468

That means the actual height is 4.468 times of shadow length. After that, you can multiply the ratio with the shadow to know the object actual size. It would be: 47 feet x 4.468=  210 feet.

Let f(x) = 5x - 4 and g(x) = x^2- 1. Find (g•f)(0).

Answers

Answer:

[tex](g\cdot f)(0)=4[/tex]

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=5x-4\text{ and } g(x)=x^2-1[/tex]

And we want to find:

[tex](g\cdot f)(0)[/tex]

This is the same as:

[tex]=g(0)\cdot f(0)[/tex]

So, find g(0) and f(0):

g(0):

Substitute 0 into g(x):

[tex]g(0)=(0)^2-1[/tex]

Square:

[tex]g(0)=0-1[/tex]

Subtract:

[tex]g(0)=-1[/tex]

And f(0):

Substitute 0 into f(x):

[tex]f(0)=5(0)-4[/tex]

Multiply:

[tex]f(0)=0-4[/tex]

Subtract:

[tex]f(0)=-4[/tex]

So, our equation is now:

[tex](g\cdot f)(0)=g(0)\cdot f(0)=(-1)\cdot(-4)[/tex]

Multiply:

[tex]=4[/tex]

So, our answer is 4.

Write the equation for the transformation of f(x) = |x| as shown in the graph.

Answers

Answer:

f(x)= 3|x-3|+1

Step-by-step explanation:

Reason why it's not +3 is because it's the reverse when graphed. But that only applies for the numbers in the brackets. If it's in the brackets and it's positive, you go to the left. If it's negative, then it goes to the right. And as you see, the V isn't on the point (0 , 3), and is in fact, above it, by 1. The graph has also been stretched vertically by 3, it looks like. Hope that was helpful for you!

Answer:

y = 2|x-3| + 1

Step-by-step explanation:

The vertex of g(x) = |x| is at (0,0)

We have moved the vertex to ( 3,1)

y = f(x) + C  C > 0 moves it up

y = |x| + 1 for the shift up 1

y = f(x + C)  C < 0 moves it right

y = |x-3|  for the shift to the right 3

y = Cf(x)  C > 1 stretches it in the y-direction

y = 2|x| since  it is stretched by a factor of 2 in the y direction

Combining

y =2|x-3| + 1

If x2 + 3x + 7 is divided by x + 2, then what is the remainder?

Answers

Answer:

ok but thx for the points

Step-by-step explanation:

The remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).

Given the polynomial; f(x) = x² + 3x + 7, since it is divided by x + 2, hence:

x + 2 = 0

x = -2

f(-2) = (-2)² + 3(-2) + 7 = 5

Hence the remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

slope 5/6, passes through (12,4)

Answer:

y= 5/6x -6

Step-by-step explanation:

[tex]m =\frac{5}{6} \\(12,4)=(x_1,y_1)\\\\[/tex]

Substitute values into point slope form

[tex]y-y_1 =m(x-x_1)\\\\y - 4 = \frac{5}{6} (x-12)\\\\y-4 = \frac{5}{6} x -10\\\\y=\frac{5}{6} x -10+4\\\\y = \frac{5}{6} x -6[/tex]

The equation of the line that has a slope of 5/6 and passes through (12, 4) will be y = 5/6) x - 6.

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is 5/6. Then the equation of the line will be

y = (5/6)x + c

The equation of the line is passing through (12, 4), then the value of c will be

4 = (5/6) 12 + c

4 = 10 + c

c = -6

Then the equation of the line will be y = (5/6)x - 6.

solve 9 = 4 + x ( show your work ) w many significant figures does the following number have: 100.00210 The Coat By: Lex Wilford Eighth grade, Mrs. Jaffreys class. It was always cold in Mrs. Jaffreys class. It was always freezing in there. And every day I wore my coat to her class she told me not to. Why not? I asked her. Its cold in here. Im cold. Because youre not supposed to wear your coat to class, she kept saying. Seemed pretty stupid to me, so I kept wearing my coat to class, I was cold. After a few days, Mrs. Jaffrey told me to hang my coat in the principals office. Told me to stay there for the rest of the afternoon. Told me to write her a five hundred-word essay on why I shouldnt wear my coat to class. Why? I asked her. I cant do that. howm I supposed to do that? She looked at me over her horned-rims. Her lips were white. She had her arms folded. The north wind coming up off the practice fields outside glazed the windowpanes along the wall with ice. Be creative, she said. I sat in the principals warm office and wrote a hundred sentences, like the ones Id written on the detention hall chalkboard for Mrs. Jaffrey after school: I will not wear my coat to class because someone might mistake me for a bear and shoot me. I will not wear my coat to class because I might sweat so much the class will flood, and somebody might drown. I will not wear my coat to class because I might get so hot, Ill catch fire and burn the whole Junior High down. That kind of thing. It was more than five hundred words. I thought it was pretty creative. Mrs. Jaffrey didnt think so, though. Neither did my old man. Next day, he showed up outside Mrs. Jaffreys class with my essay in his hand. Checked me out of school. Told me to put on my coat. Its in the principals office, I told him Leave it then, he said. It was cold outside. Ice coated the trees, the rooftops of houses, the windshields of cars parked along the curbs, the sidewalks, the streets. The old man drove too fast, dodging fallen tree limbs in the road, his pickup truck sliding all over, down to Pecan Park. He told me to get out. Told me to open the tailgate. Told me to bend over and read each sentence, one at a time. There was a new two-by-four in the bed of the truck. The wood was white. He picked it up, stood behind me. I read a sentence, and then he hit me one. Then I read another sentence. He hit me again, there were a hundred sentences. He kept hitting me. The wind blew up hard and it started to sleet, and all around the park tree limbs groaned and cracked and snapped off. I didnt have my coat on. I was cold. Ice fell all around me.
