I think the correct answer from the choices listed above is option B. It would be an indirect proof that is not an acceptable form of proof. This is because this type proof is not used by any problem. Hope this answers the question. Have a nice day.

Answer:

Conjecture proof

Step-by-step explanation:

 In the field of mathematics, conjectures means arriving at a conclusion without complete or proper information, for which the proof or disproof have to be found yet. It is a statement in mathematics that has not been proved rigorously.  Conjectures come into picture when someone notices a definite pattern which can hold true for some cases but that does not confirm that these patterns also hold true for all the other cases. Thus Conjecture proof is not fully accepted.

Listed below are the durations​ (in hours) of a simple random sample of all flights of a space shuttle. Find the​ (a) mean,​ (b)
-Dominant- [34]

Answer:

Mean = 212.93

Median = 231

Mode = 231

Mid range = 192.5

(B) ​Yes, the time of 0 hours is very unusual. It could represent a flight that was aborted.

Step-by-step explanation:

We are given the following data set:

8, 92, 231, 189, 169, 267, 196, 381, 257, 231, 385, 330, 219, 239, 0

Formula:

a)

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{3194}{15} = 212.93

b)

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Sorted data:

0, 8, 92, 169, 189, 196, 219, 231, 231, 239, 257, 267, 330, 381, 385

\text{Median} = \dfrac{15 + 1}{2}^{th}\text{ term} = 8^{th}\text{ term} = 231

Mode is the most frequent observation in the data.

Mode = 231

It repeated 2 times.

\text{Mid range} = \dfrac{\text{Maximum value + Minimum value}}{2}\\\\= \dfrac{385 + 0}{2} = 192.5

0 is an outlier to the given dataset. Thus,

Option (B) ​Yes, the time of 0 hours is very unusual. It could represent a flight that was aborted.

Simplify 4x+3y please
77julia77 [94]

Answer:

\boxed{4x + 3y}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well 4x + 3y cannot be added together because they are 2 different variables.

4x + 3y = 4x + 3y

So 4x + 3y simplified is,

<h2>4x + 3y</h2><h2></h2>

<em>Hope this helps :)</em>
