#1- Jennifer made a box plot to summarize this data. 124, 118, 129, 139, 133, 129, 142, 135, 122, 137. What is the median, the l
svp [43]
Answer:
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Step-by-step explanation:
To find the median first make the data in order from greatest to least:
118,122,124,129,129,133,135,137,139,142
Then find the middle 2 numbers which are 129 and 133
129+133=262 (divide by 2 to find average) so
median= 262/2=131
To find the Lower quartile find the number in the middle of the first 5 numbers which is 124
To find the Upper quartile find the number in the middle of the second 5 numbers which is 137 so
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Answer:
Step-by-step explanation:
8x-14=2x+11
-8 -8
-14=-6x+11
-11
-25=-6x
/-6
x=4.16
Ben's estimate gives 7 g of nickel; the actual amount is 8.03 g.
In 1 g of the substance, there is 0.52 g of copper and 0.25 g of zinc; this gives
0.52+0.25 = 0.77 g of the substance.
The remaining part of the substance is nickel:
1-0.77 = 0.23 g of nickel.
Using Ben's estimate, 0.2 g of nickel per gram of substance, we have
0.2(35) = 7 g of nickel in 35 g of the substance.
The actual amount is 0.23(35) = 8.03 g of nickel in 35 g of the substance.
Mean = 62 in
SD = 2 in
At 16% = 0.16 and using Z tables,
Z≈ -0.99
x =(-0.99*2) + 62 ≈ 60 in
This represents jockeys who are shorter than 60 in.
