The observations of 124.53, 124.55, 142.51, and 124.52 are obtained when taping the length of a line. What should the observer c

mylen [45]

Answer: the observer should consider to eliminate or to retake the third measure.

Explanation:

The four measures taken are 124.53, 124.55, 142.51 and 124.52.

As it can be easily seen, the third measure is much different from the other three. This means that something went wrong during the observation: it can be either the measure taken wrong or that the number was written wrong (if you switch the 2 and the 4 you get a number similar to the other ones).

If the third measure is not considered, an estimate of the mean would place it around 124.5, while if the outlier (the detatched number) is considered an estimate of the mean would increase to about 129.

Therefore, in order to obtain a more reliable mean, the observer should consider to eliminate or to retake the third measure.

You download eight songs onto a music player. If you play three of the songs using the random shuffle option, how many ways can

Dmitrij [34]

Every time you play a song 8 different songs can be played, since you do this 3 times:
$8 \times 8 \times 8 = 512$
Or, an easier way to write this if play them many times:
${8}^{3} = 512$
In which the 8 is how many options and the 3 how many times you play.

Round to the nearest tenth if necessary. Find the distance between the two points. (–1, –8), (–4, –4) A)5 B)25 C)13 D)1

jeyben [28]

Answer: (a)

Step-by-step explanation:

Given

The points are $(-1,-8)$ and $(-4,-4)$

The distance between two points $(x_1,y_1),(x_2,y_2)$ is given by

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

Apply the distance formula

$\Rightarrow d=\sqrt{\left( -4+1\right)^2+\left( -4+8\right)^2}\\\\\Rightarrow d=\sqrt{(-3)^2+(4)^2}\\\Rightarrow d=\sqrt{9+16}\\\Rightarrow d=5\ \text{units}$

Hence, option (a) is correct.
