Answer:
15 students
Step-by-step explanation:
No. of boys students = No. of all students - No. of girls
no. of boys =50-15 = 35 boys
the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys
and the girls that will play the match are 5 girls
so, no of students chosen to play = 5+10=15 students
You can't have two odd numbers equal an odd number(143).
For f(10) replace x with 10 then solve:
f10) = 10^2 + 1
= 100 +1
= 101
Is {(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)} a function?

Answer: no
Step-by-step explanation:
Each of the domain values, x, output a single value, y, in a function.
This set is a not function, because the domain value 3 has two outputs.
Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404
