Answer:
the score that occurs most frequently
Solution:
The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes.
On analysing the graph ,
![\left\begin{array}{ccc}s&v\\0&0\\2&1\\4 &8\end{array}\right](https://tex.z-dn.net/?f=%20%5Cleft%5Cbegin%7Barray%7D%7Bccc%7Ds%26v%5C%5C0%260%5C%5C2%261%5C%5C4%20%268%5Cend%7Barray%7D%5Cright%20%20)
This table shows how the volume, V, of the cube changes as the length of the sides, S, changes.
Option C is the correct option for the table that matches the graph.
20/10 as a mixed number:
20 ÷ 10 = 2.
10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2.
20/10 = 2
Answer:
2s + 30 = 2s
Step-by-step explanation:
Time up hill + time down hill = total time
:
Multiply equation by 30s; results
2s + 30 = 2s

Answer:
υ= 25
Step-by-step explanation:
IF we have two small independent samples from two normal populations with means μ1 and μ2 and standard deviations σ1 and σ 2 but unknown ,then the unbiased pooled or combined estimate of the common variance sigma square ha s student's t distribution with degrees of freedom given by
υ= n1+ n2- 2
In the given question
Sample A size= n1= 12
Sample B size = n2= 15
υ= 12+15-2
υ= 25
where
sp²= (n1-1) s1² + (n2-1) s2² / n1+n2-2
