What are the minimum, first quartile, median, third quartile, and maximum of the data set?
allochka39001 [22]
If we rearrange the given data set from lowest to highest, we have 
     3,\:6,\:7,\:8,\:10,\:12,\:15,\:18

The minimum is 3.

The first quartile is the average of 6 and 7, which is 6.5

The median is the average of 8 and 10 which is 9.

The third quartile is the average of 12 and 15 which is 13.5.

The maximum is 18.

PLS I NEED HELP I WILL REALLY APPRECIATE IF SOMEONE DID IT I WILL MARK YOU THE BRAINLY PLS HELP!!!!
VLD [36.1K]

Answer:

1) b= 39.5

2) c= 3.6

3) a=19

Step-by-step explanation:

Use the Pythagorean Theorem to find the missing side length.

"C" is the hypotenuse. Pythagorean Theorem: a^2+b^2=c^2

1) 11^2+b^2=c^41

121+b^2=1681

121-121+b^2=1681-121

b^2=1560

b= 39.5

2) 2^2+3^2=c^2

4+9=c^2

13=c^2

c= 3.6

3) a^2+9^2=21^2

a^2+81=441

a^2+81-81=441-81

a^2=360

a=19

Hope this helps!
