1. what are the mean, median, mode and range of the data set given the altitude of lakes in feet: –
11, –28, –17, –25, –28, –39, –6, and –46?
(1 point)
a. mean = –25; median = –26.5; mode = –28; range = 40
b. mean = –25; median = –40; mode = –26.5; range = 28
c. mean = –26.5; median = –25; mode = –28; range = 28
d. mean = –26.5; median = –28; mode = –25; range = 40

2. given the data 21, 13, 13, 37, 13, 23, 25, 15:
a. what is the outlier in the data?
b. what is the mean with the outlier?
c. what is the mean without the outlier?

a. 13; 21; 17.6
b. 37; 20; 17.6
c. 37; 17.6; 20
d. 13; 17.6; 21

the mean and mad

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

my answer is$ 12

step-by-step explanation:

because 15 -2=12

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
