Answer 2

A data set's mean is the average of a data set. The mean of this data set is 7.2.

What is the mean of a data set?

A data set's mean (average) is calculated by summing all of the numbers in the set and dividing by the number of values in the set.

The mean of this data set can be written as,

[tex]\rm Mean = \dfrac{4+7+13+3+9}{5} = 7.2[/tex]

Hence, the mean of this data set is 7.2.

Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determine two values of x that support your conclusion.

28
__ = 0
x

Answers

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.

Give a set of 5 items of data that has a mode and median of 54 and a mean of 57.

Please help!! I would really appreciate it.

Answers

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.

A. The right side of the equation should be -4 after subtracting -24 from each side.
B. The left side of the equation should be - b after dividing each side by -4.
C. The left side of the equation should be b after distributing.

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.

Convert 45°C to Fahrenheit using the formula F = 9/5 C + 32.

Answers

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.

Choose the correct fraction and decimal equivalent for 78%.
To solve this correctly you will need to remember how to estimate percents using decimals and fractions.

39/50

7.8/100

78.0

0.78

Answers

Answer: 0.78 and 39/50

Explanation:

What we know:

We need to find 78% as a fraction and decimal

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.

Process:

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

The two answers would be .78 and 39/50.

Can someone explain how to find the length of triangles? I watched some videos and looked things up but none make sense. (with numbers so basically 12 cm, 13 cm, 24 cm. That kind of thing)

Answers

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.
