Answer:

The surface area is 972 square cm

Step-by-step explanation:

Numeric Value of Functions

Given the function:

A = 252 + 4sh

Where A is the surface area of a square prism , s is edge length of the base  h is the height.

A square prism has a base with edges s=12 cm long and height of h=15 cm.

Substituting these values, we get:

A = 252 + 4(12)(15)

A = 252 + 720 = 972

A = 972

The surface area is 972 square cm

The surface area of the square prism is 1008 cm².

Surface area of a square prism:

where

s = edge side

h = height

Therefore,

s = 12 cm

h = 15 cm

surface area = 2 × 12² + 4 × 12 × 15

surface area = 2 × 144 + 48 × 15

surface area = 288 + 720

surface area = 1008

surface area = 1008 cm²

Answer:

The best option is: When the number of procrastination days is 0, the predicted grade is 96.5 points.

Option D is correct option.

Step-by-step explanation:

The regression equation given is: [tex]y= -3.64x + 96.5[/tex]

where x represents the number of procrastination days and ŷ is the predicted grade.

Which statement best describes the meaning of the y-intercept of the regression line?

First we need to identify what is y-intercept in regression line.

The y-intercept of the regression line is the value of output y when x is 0.

So, when x = 0, the value of output is y-intercept

So, if x = 0

we get:

[tex]y= -3.64x + 96.5\\y= -3.64(0) + 96.5\\y=0+96.5\\y=96.5[/tex]

So, the best option is: When the number of procrastination days is 0, the predicted grade is 96.5 points.

Option D is correct option.

Answer:

1) View image attached

2) -3, -2.5, -1, 2, 5

3) -2.5

Step-by-step explanation:

1) Draw a number line, an image is shown below with the number line. You then put "points" on the values that you are plotting. This is also shown in the image attached.

2) The ones with the "-" are negative, meaning that they are below 0. These will always be smaller than those without a "-" sign. In addition to this, the way negative numbers work in terms of least to greatest is completely flipped. For example, -5 is greater than -10, and -10 is less than -5. If the numbers were positive, 5 would be less than 10 and 10 would be greater than 5.

3) The value that isn't an integer is the one that isn't a whole number. In those answer choices you gave, the only one with a decimal is -2.5 (as indicated by the ".5"

Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.

Step-by-step explanation:

3x+X+60=180

4x=180-60

X=120/4

X=30

Answer: All I want for Christmas is you lyrics lol

I don't want a lot for Christmas

There is just one thing I need

I don't care about the presents

Underneath the Christmas tree

I just want you for my own

More than you could ever know

Make my wish come true

All I want for Christmas is you, yeah

I don't want a lot for Christmas

There is just one thing I need

And I don't care about the presents

Underneath the Christmas tree

I don't need to hang my stocking

There upon the fireplace

Santa Claus won't make me happy

With a toy on Christmas Day

I just want you for my own

You, baby

Oh, I won't ask for much this Christmas

I won't even wish for snow

And I'm just gonna keep on waiting

Underneath the mistletoe

To the North Pole for Saint Nick

Hear those magic reindeer click

'Cause I just want you here tonight

Holding on to me so tight

What more can I do?

Baby, all I want for Christmas is you

You, baby

Oh, all the lights are shining so brightly everywhere

And the sound of children's laughter fills the air

And everyone is singing

I hear those sleigh bells ringing

Santa, won't you bring me the one I really need?

Won't you please bring my baby to me?

Oh, I don't want a lot for Christmas

This is all I'm asking for

I just wanna see my baby

Standing right outside my door

Oh, I just want you for my own

More than you could ever know

Make my wish come true

Baby, all I want for Christmas... is you

You, baby

All I want for Christmas is you, baby

All I want for Christmas is you, baby

All I want for Christmas is you, baby

All I want for Christmas is you, baby

Answer:

y = -2x + 7

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the point (3,1) and (7,-7), calculate the slope:

[tex]\displaystyle m=\frac{-7-1}{7-3}[/tex]

[tex]\displaystyle m=\frac{-8}{4}=-2[/tex]

m = -2

No w we use any of the given points: (3,1) and substitute in the equation of the line:

y - 1 = -2 ( x - 3 )

Multiplying:

y - 1 = -2x + 6

Adding 1:

y = -2x + 7
