Answer:
Minimum value = 2
Maximum value = 26
Lower quartile = 4
Median = 14
Upper quartile = 20.5
Step-by-step explanation:
Five number summary:
- Minimum value
- Maximum value
- Lower quartile
- Median
- Upper quartile
Assuming the stem is the tens column and the leaves are units, the data values are:
2, 2, 3, 5, 7, <u>13, 15</u>, 16, 20, 21, 24, 26
Minimum value = 2
Maximum value = 26
<u>Median</u> - middle value
As there is an even number of data values, the median is the mean of the 6th and 7th data values.
Median = (13 + 15) ÷ 2 = 14
<u>Lower quartile</u>
As there is an even number of data values, the lower quartile is the mean of the 3rd and 4th data values.
Lower quartile = (3 + 5) ÷ 2 = 4
<u>Upper quartile</u>
As there is an even number of data values, the upper quartile is the mean of the 20th and 21st data values.
Lower quartile = (20 + 21) ÷ 2 = 20.5

Q: What is the most they could weigh together?
A: 0.74 kg

Q: What is the least they could weigh together?
A: 0.62 kg
=================================================
Work Shown:
x = weight of first ball
y = weight of second ball
each ball has a weight range of 0.31 kg to 0.37 kg, so,
add straight down to get
which simplifies to
the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.
--------
Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
The constant between two consecutive terms is called the common difference.
The answer to the question is (0,5)
Answer:
18ft
Step-by-step explanation:
L = length
W = width
l = w + 2ft ; because the is 2 ft longer than width
The area of a rectangle is lw
You can take the first equation ( l = w + 2 ) and plug it in lw
like this: lw ---> (w+2)w = w^2+2w
then from the question you get: w^2+2w=19.25
you use the quadratic formula and get w = 3.5
then from the first equation, you get l = 3.5+ 2 so the length is 5.5
lastly, you use the perimeter formula: 2(l+w) so 2(9) = 18
so 18ft
