With data, you can have outliers. Outliers are values that do not follow what the range or majority of the data you collected so a value of 45, 42, 45, 48, 42, 44, 88, the mean will obviously be different because the 88 is going to change the whole data. But, if you put it from least to greatest, you can see what the majority of data is, (what the middle value is) to see what is in the middle range of what you have collect- the outliers don't affect what you have. Hence, 42, 42, 44, 45, 45, 88 (it's not much data) but it can show what the majority of data is. Hope this helps :> :)

Answer:

When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.

Joe was planning a business trip to Canada, so he went

nika2105 [10]

Answer:

2203.20 pesos

Step-by-step explanation:

Joe's original amount was $200

#We convert this amount to $CDN:

$\$1=1.02\$CDN\\\\=200\times 1.02\\\\=204\$CDN$

Joe now has to convert the Canadian dollars to Mexican pesos(at a rate of 10.8 pesos per $1 CDN):

$=204\times10.8\\\\=2203.2$

Hence, he gets a total of 2203.20 pesos in exchange for his Canadian dollars.

A sample of 6500 automobiles found that 1560 of the automobiles were black, 3120 of the automobiles were sedans, and 1170 of the

andriy [413]

Answer:

P=0.54.

Step-by-step explanation:

We know that in a sample of 6500 automobiles found that 1560 of the automobiles were black, 3120 of the automobiles were sedans, and 1170 of the automobiles were black sedans.

We calculate the number of sedans that are not black:

3120-1170=1950

We calculate the number of black cars that are not sedans:

1560-1170=390

The number of automobiles which are black or a sedan is

1950+390+1170=3510.

The probability that the automobile is black or a sedan is:

P=3510/6500

P=0.54.

The panthers team won exactly 2 of its first 9 games. By winning all its remaining N games, the Panthers ended with victories in

Soloha48 [4]

Answer:

Step-by-step explanation:

2 out of 9 games won

After the N games, the games won would be HALF. Thus, we can write a ratio and solve for the variable N:

$\frac{2+N}{9+N}=\frac{1}{2}$

Now we cross multiply and solve for N [the number of remaining games that all are won]:

$\frac{2+N}{9+N}=\frac{1}{2}\\2(2+N)=1(9+N)\\4+2N=9+N\\2N-N=9-4\\N=5$

N represents 5

Someone please help me and solve for the unknowns and give reasons please

Ann [662]

Answer:

Step-by-step explanation:

The angles labeled with 2x, 4x, and 3x are on a straight line so their sum is equal to 180

2x + 4x + 3x = 180 add like terms

9x = 180 divide both sides by 9

x = 20

The angle represented with 3x - 30 and the angle represented with 2x + 10 are alternate and their measurement is same

3x - 30 = 2x + 10 export like terms to same side of the equation

3x - 2x = 10 + 30

x = 40

to find the angles replace x with the value found for each.
