Answer:
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 %
Step-by-step explanation:
Given as ;
The total number of first year students in an university = 250
The number of student who like to listen classical music = 12 out of 250
Let x % of student like to listen classical music
So, x% of 250 = 12
or, × 250 = 12
or, x × 250 = 12 × 100
Or, x =
∴ x = 4.8
I.e the percentage of first year student like to listen classical music is 4.8%
Now, Again
The 10% of the total number of student is
I.e 10% of 250
or, × 250
Or ,
I.e The 10% of the total number of student = 25
Since 4.8 % of total number of students is 12 and 10% of total number of students is 25
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 % . answer
Answer:
=
(3n + 7)
Step-by-step explanation:
We require to find the first term a₁ and the common difference d
The n th term is given by 3n + 2, thus
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
d = 8 - 5 = 3
=
[ 2a₁ + (n - 1)d ], substitute values
=
[ (2 × 5) + 3(n - 1) ] =
(10 + 3n - 3) =
(3n + 7)
