What is the mean of this data set?

{4, 7, 13, 3, 9}

Enter your answer as a decimal in the box.

Answer:

113 degrees Fahrenheit

Step-by-step explanation:

If you take 9/5 of 45, or 180%, you get 81.

Then it's just 81 + 32 = 113.

If you are allowed to use a calculator, a very easy way to do this is 9/5(45) + 32. Of course, replace the 45 with whatever Celsius temperature you've been given.

Answer:

B = 7

Step-by-step explanation:

All the answers you listed are wrong. It should be D but the reasoning is wrong. When you distribute the -4 to the expression in the parenthesis you end up with -23 + 4b as a negative times a negative equals a positive. Therefore that's where the error initially lies.

/ means divide

* means multiply

9.

you have to do parenthesis first

2 * 11 = 22

3 * 10 = 30

2 * 9  = 18

10.

12 + 2 = 14

18 + 3 = 21

24 + 4 = 28

4/1 = 4

36/2 = 18

Answer: 0.78 and 39/50

What we know:

How to solve:

The decimal is easy enough, and then the fraction can be found from there. D will represent decimal, p will represent percentage, and F will represent fraction.

Decimal

Set up equation                                                 D = p / 100

Substitute                                                           D = 78% / 100

Simplify                                                               D = 0.78%

Remove % sign                                                  D = 0.78

Fraction

Set up equation                                                 F = p / 100

Substitute                                                           F = 78% / 100

Remove % sign                                                  F = 78 / 100

Simplify if needed                                            F = /2    /2

                                                                           F = 39 / 50

Solution: 0.78 and 39/50

Check:

Multiply the decimal by 100 to check the decimal

0.78 x 100 = 78; 78%

Divide the fraction to check the fraction

39/50 = 0.78; see above

Answer:

No solutions.

Step-by-step explanation:

No quotient can ever be equal to 0, as the closest you can get is -1 or 1.

As for the second part -- "afterwards, determine two values of x that support your conclusion." -- I'd assume that's more for if X has an infinite number of solutions, but I suppose if you needed to show those two values still, you could also just show two values failing to be equal to 0 in this scenario. (e.g 28/1 = 28, etc.)

Answer:

396 mm

Step-by-step explanation:

Lets start off by writing what we know:

We know that a single line mark means 11 mm

We know that a double line mark means 15 mm

We know that a triple line mark means 9 mm

We are going to cut the shape into three rectangular sections (shown in the image)

We are going to solve for the area for each of those rectangles

15 * 11 = 165

6 * 11 = 66

15 * 11 = 165

165+165+66 = 396 mm

Answer:

Any c answer that fits 5 <c<37 is correct.

Step-by-step explanation:

Say the three sides of the triangle are  

a

,

b

and  

c

. Here,  

a

=

16

and  

b

=

21

. We must find the possible values of  

c

.

Since  

a

+

c

>

b

, we can input:

16

+

c

>

21

c

>

5

.

So the lower bound of  

c

is everything above  

5

.

We also know that  

a

+

b

>

c

. Inputting:

16

+

21

>

c

37

>

c

.

So  

c

must be less than, but not including  

37

.

In conclusion, the side length  

c

must satisfy the following inequality:

Required number of square inches of cardboard =

                                                          =area of central square+

                                                                     4 x area of each triangle shape

                                        =2 x 2 + 4 x { 1/2 x 2 x 5 }

                                       = 4  + 4 x {5}

                                         = 4 + 20

                                       = 24 square inches

Answer:

Hello! There are a variety of answers, see below :)

Step-by-step explanation:

We need five data items. The middle one needs to be 54, and the average needs to be 57. There also needs to be more than one 54 because that is also the mode.

A B 54 C D

Okay, so first multiply 57 by 5, because we need to find the total sum using the average. 57 * 5 = 285

That means that our five numbers need to equal 285 as well so they can have the same average.

53, 54, 54, 61, 63 is one way

50, 52, 54, 54, 75 another ect

We just take the average times the number total, subtract the numbers we already know (54 and 54) and then find three other numbers that also equal 285.

Answer:

3x+1 is y2

Step-by-step explanation:

Answer: C, It is the same shape and size as the figure.

Step-by-step explanation: The size and shape do not change when you rotate it, it only moves the shape to a different location, no dilation occurs.

[tex] \qquad \quad\huge \bf༆ Answer ༄[/tex]

The Correct choice is ' C '

It's the same shape and size as the figure, rotation about origin doesn't cause change in shape or size. it just displaces the coordinates of different points of that figure.

These angles are Congruent

Answer:

congruent

Step-by-step explanation:

that means, if placed with the same orientation on top of each other, they would completely cover each other up both ways.

Check the picture below, there are two cases, case of option B and case of option C for Lorelei, we are looking at only the two smaller sides.

on option B

we have sides of 12 and 13, now, if we move the sides closer and closer to be one on top of the other, what is left is just one unit of slack, because the side of 12 laying right on top of the side of 13, is short by 1 unit to be 13, however if we do that, we no longer have a triangle, just two pancaked lines, so whatever the 3rd side may be, it must be greater than 1 unit.

now, if we instead move the sides away from each other, to the extent that sides 12 and 13 make a flat line, well, a flat line will be as long as 12 + 13 = 25, however, we can't do that becuause, again if we do so, all we have is a flat-line, and no longer a triangle, so, whatever the 3rd side may be, it must be less than 25 units.

well, on option B, we have a 3rd side given as 25, but we can't use that, because we'd be losing our triangle, we'd only be left with a flat line, so no dice on B.

on option C

as you see in the picture, same thing, pancake one side on top of the other and there's no slack, so the 3rd side must be greater than 0.

now move the sides away from each other and their sum gives 10 + 10 = 20, so the 3rd side must be less than 20.

we're given a 3rd side of 24, how the dickens are we going to get a side to be 24 when both sides of 10 extended only give 20? not going to happen, so no dice on C.

needeless to say the sides of 12, and 14 provide for a 3rd side of greater than 2 and less than 26, well, 24 is indeed within that range.

It would be an improper fraction a = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

An improper fraction is when a fraction in which the numerator is greater than the denominator.

Answer:

[tex] - \frac{1}{2} = - \frac{5}{6} + \frac{1}{4} a \\ \\ \frac{1}{4} a = - \frac{1}{2} + \frac{5}{6} \\ \\ \frac{1}{4} a = - \frac{3}{6} + \frac{5}{6} \\ \\ \frac{1}{4} a = \frac{2}{6} \\ \\ \frac{1}{4} a = \frac{1}{3} \\ \\ a = \frac{4}{3} = 1.33[/tex]
