Answer:
d = 6
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₄ = 23 and a₁₁ = 65 , then
a₁ + 3d = 23 → (1)
a₁ + 10d = 65 → (2)
Subtract (1) from (2) term by term to eliminate a₁
10d - 3d = 65 - 23
7d = 42 ( divide both sides by 7 )
d = 6

rounded its 66%
Step-by-step explanation:
We know that
38% of the incoming students own both a smartphone and a tablet
84% of the students own a smartphone
We are asked to find the percentage of students who own a smartphone
Let N be the total number of incoming students and S be the total number of students
So,
(N (38%) + S (84%)) / (N + S)
If we know the total number of students or incoming students, we can solve for the percentage by substituting the value of N or S
