Answer:

The mean of the temperatures is 13.5 without the outlier.

Step-by-step explanation:

To find the mean, you add all of the numbers in your data set and divide that  by how many numbers you added.

Before we do this, we must first identify the outlier and remove it from our calculations since it is asking us to find the mean without it. 41 is the outlier because it is a considerably larger number than the other numbers in the data set.

Equations: 11 + 11 + 13 + 14 + 15 + 17 = 81

                  81 ÷ 6 = 13.5

False, -4(X - 5) would be -4x + 20.

Answer:

Multiply each side by −5, add 25 to each side

Step-by-step explanation:

-1/5(x-25) = 7

Multiply each side by -5/1 to clear the fraction

-5/1* -1/5(x-25) = 7*-5/1

x-25 = -35

Then add 25 to each side

x-25+25 = -35+25

x = -10

Answer:

D. Pyramid

Step-by-step explanation:

A. cone does not have any triangular faces

B. does not have any triangular faces either

C. Prism may have triangular faces if it is a triangular prism but they do not meet at a vertex

Therefore it must be D.

A pyramid is a solid has a base that is a polygon and triangular faces that meet at a vertex.

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex.

Pyramids :-

A pyramid is defined as a three-dimensional structure encompassing a polygon as its base. The Great Pyramid of Giza, which is structured in the same concept. Every corner of this structure is linked to a single apex which makes it appear as a distinct shape.

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex, and forms the triangular face, called the lateral face. If a pyramid has an n-sided base, then it has n+1 faces, n+1 vertices, and 2n edges.

Answer:

The teacher will have 5 pints left.

Step-by-step explanation:

One pint has 16 fluid ounces, therefore if the teacher got 18 pints he has a total of:

lake water = 18*16 = 288 fluid ounces

If each student use 4 fluid ounces, and there are 52 students the class will use:

used = 52*4 = 208 fluid ounces

And the remainder will be:

remainder = 288 - 208 = 80 fluid ounces

remainder = 80/16 = 5 pints

The teacher will have 5 pints left.

Answer:

38 ft

Step-by-step explanation:

Let x  and (3x+2) represent the width and length respectively:

L + W = P/2 = 100/2 = 50

 (3x+2) + x = 50

     4x = 48

      x = 12ft, the width, the length is 38ft

Answer: Kiyo only accounted for one side of the path when creating his equation. There are 2 feet of path on each side of the garden, meaning there should be 4 extra feet added to each expression multiplied.

Step-by-step explanation:

The rectangular path surrounding the garden is 2 feet on each side.

The length of the garden is represented by 3x, but when the length of the path is included, there is 2 feet of path on the left of the garden and 2 feet of path on the right.

Due to this, Kiyo made the mistake of only including 2 feet instead of the full 4 of the path by only accounting for one side of the path.

The correct equation is:

Answer:

B ( 432 units^2)

Step-by-step explanation:

Total surface area= 2*(6*6)+ 4*(15*6)

There are 2 squares at each end of the same size so total area will be 2*(6*6)

If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)

In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2

Answer:

x=17

Step-by-step explanation:

to find x use this

[tex]\frac{x}{2} =8.5[/tex]

x=8.5*2=17

Answer:

x=17

Step-by-step explanation:

To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

x/2=8.5

x is being divided by 2. The opposite of division is multiplication. Multiply both sides by 2.

2*x/2=8.5*2

x=8.5*2

x=17

To check the solution, substitute 17 in for x in the original equation.

Original equation: x/2=8.5

Substitute 17 in for x: 17/2=8.5

17/2=8.5

8.5=8.5

This is true, so we know that x is equal to 17.

We have been given that that function [tex]y=3(x-5)^2[/tex] is obtained from the graph of [tex]y=x^2[/tex]. We are asked to find the two transformations that can be used to obtain the transformed function.

We will use transformation rules to solve our given problem.

[tex]f(x-a)\Rightarrow\text{Graph shifted to the right by a units}[/tex], where a is any positive number.

We can see that the value of a is 5 for our given function, therefore, graph is shifted to right by 5 units.

Now we will use scaling rules.

[tex]f(x)\Rightarrow a\cdot f(x)[/tex]

If [tex]a>1[/tex], then function is stretched vertically by a factor of 'a'.

If [tex]a<1[/tex], then function is compressed vertically by a factor of 'a'.

We can see that value of a is 3. Since 3 is greater than, so function will be stretched vertically by a factor of 3.

Therefore, the function can be obtained by a vertical stretch and translation of 5 units to right and option J is the correct choice.

Answer:

3/8 inches

Step-by-step explanation:

The postcard must be less than 4 1/2 inches high.

Elayne's postcard is 4 7/8 inches high.

We need to subtract the limit from the height of her postcard to know how high it is above the limit:

4 7/8 - 4 1/2 = 3/8

Her postcard is higher than the limit by 3/8 inches.

The answer is 3/4 or 1 1/2 inches.

Answer: $122.19

Step-by-step explanation:

Hi, to answer this, first we have to calculate the additional KB that Astrid used:

KB used- KB limit=

6,978-5,000 = 1,978

Then, the cost of the plan is equal to a fixed fee (49) plus the product of the number of additional KB over 5,000(x) and the cost per KB (0.037).

Cost = 49+ 0.037 x

Substituting x =1,978

C = 49+ 0.037 (1,978)

C =49+73.186

C=$122.19
