<u />The data is <u>Skewed right</u><u /> since most of the data is on the left side, the right side points are screwing up the mean and median.

Answer with explanation:

Writing the data values which is represented on the line plot

0,0,0,0,1,1,1,1,1,2,2,2,2,2,2,2,2,3,3,3,3,4,4,5,8,10

There are 26 variate in the data set.

Mean of the data set is

$M=\frac{0\times 4 +1\times 5 +2\times 8+3\times 4+4\times 2+5\times 1+8\times 1+10\times 1}{26}\\\\=\frac{0+5+16+12+8+5+8+10}{26}\\\\=\frac{64}{26}\\\\=2.47$

Median ,as there are even number of variate in the data set

$=\frac{2+2}{2}\\\\=2$

Mode , which is maximum number of times occurring variate in the data set

→Mean > Median and Mode

So, Data is Skewed Right.

Answer:

did that first one its false

A= 53, B= 100, C= 27 (the last option)

BC is the longest side because it is opposite the largest angle ( not true)

Select all of the following statments that are true

Nonamiya [84]

Answer:

A. -¾ + 0 = -¾

B. -¾ - ¾ = -(¾ + ¾)

C. ¾ - ¾ = ¾ + (-¾)

E. -¾ + ¾ = ¾ + (-¾)

F. -¾ + ¾ = 0

Step-by-step explanation:

Let's check each equation to determine whether they are true or false.

If what we have in the both sides are equal, then the equation is true, if they're not, them it is false.

✔️-¾ + 0 = -¾

Add everything on your left together

-¾ = -¾ (TRUE)

✔️-¾ - ¾ = -(¾ + ¾)

Add everything on both sides together respectively

(-3 - 3)/4 = -(3 + 3)/4

-6/4 = -6/4 (TRUE)

✔️¾ - ¾ = ¾ + (-¾)

0 = ¾ - ¾ (+ × - = -)

0 = 0 (TRUE)

✔️-¾ + ¾ = ¾ - (-¾)

0 = ¾ + ¾ (- × - = +)

0 = 6/4 (FALSE)

✔️-¾ + ¾ = ¾ + (-¾)

0 = ¾ - ¾ (+ × - = -)

0 = 0 (TRUE)

✔️-¾ + ¾ = 0

0 = 0 (TRUE)

If a scale distance of 3.5 inches on a map represent an actual distance of 175 km what actual distance does a scale distance of

gavmur [86]

Considering the definition of map and scale, an actual distance of 269.59 km represent a scale distance of 5.7 inches .

<h3>Definition of map and scale</h3>

A map is a representation of a place, at a size smaller than the real size.

The scale of a cartographic representation is the relationship of similarity between the real dimensions of the geographical space represented and those of its image on the map. That is, the scale is defined as the proportionality relationship that exists between a distance measured on the ground and its corresponding measurement on the map.

One way to represent the scale is by a fraction, which indicates the proportion between the distance on a map and its corresponding distance in reality:

$Scale=\frac{distance on the map}{distance in reality}$

<h3>Actual distance in this case</h3>

In this case, you know that a scale distance of 3.5 inches on a map represent an actual distance of 175 km.

To know the real distance that represents a scale distance of 5.7 inches, as the scale ratio is the same as in the previous case, it is expressed:

$\frac{3.7 inches}{175 km}=\frac{5.7 inches}{distance in reality}$
