Answer: 145 cans
Step-by-step explanation:
arithmetic sequence
aₙ = a₁ + (n-1).r
aₙ → last term
a₁ → 1st term
n → quantity of terms
r → common difference
a₁ = 1 (one can at the top)
aₙ₋₁ = 25
aₙ = 28
To find out How many cans are in the entire display, we need the SUM of the arithmetic sequence: S = (a₁+aₙ)n/2
∴
S = (1+28).n/2
n = ?
aₙ = a₁ + (n - 1).r
r = 28 - 25 = 3
28 = 1 + (n - 1).3
27 = (n - 1).3
27/3 = (n - 1)
9 = n - 1
n = 9 + 1 = 10
S = (1+28).n/2
S = (1+28).10/2 = 29.10/2 = 29.5 = 145
Answer:
- The minimum height is 154 cm
- The first quartile Q1 is 168.8 cm
- The second quartile Q2 (or the median) is 171.9 cm
- the maximum height is 193 cm
Step-by-step explanation:
Box plot allows to identify minimum point, maximum point, Q1, Q3 and the median.
See the below (attached) image for the locations of the minimum point, maximum point, Q1, Q3 and the median.
