Answer:
1 1/2 lbs
Step-by-step explanation:
290
Because 2*100= 200
and 9 is 9 more than 0
1st find the averages of each one:
Elizabeth average of reading in min =(18+36+15+45+88+57+12)/7 =38.71 min
Sam average of reading in min =(17+52+48+35+13+71+16)/7 =36 min
question:
1) No
2) YES. [the range is te difference between the largest & the smallest)
Eliz Range = 88-12 =76 & Sam's= 71-13 = 58
3) NO. Sam 71 min & Eliz 88 min
4) YES. Median Eliz =45 min. Median Sam =35 min
Answer:
B = 2
Step-by-step explanation:
( 2 b + 4 ) 2 − 12 = 0
Distribute..
2b+4(2)-12=0
combine like terms
2b+8-12=0
2b-4=0
Now solve this simple 2 step equation...
2b-4=0
+4=+4 <- add 4 to both sides
----------
2b=4
/2 = /2 <- divede both sides by 2
-----------
B = 2
