Y = 110x + 5600
since x = 0 corresponding to 1982, x = 1 corresponding to 1983 so it must be x= 5 in 1987
we can put the value of x which is 5 in the equation
y = 110 (5)+ 5600
y = 550 + 5600
y = 6150
they sold 6150 units
-5(2-w)+7/3w-12/3
-5(2-w)+7/3w-4
-10+22/3w-4
-14+22/3w
22/3w-14
Answer:
Step-by-step explanation:
There are a total of 10 persons (6 teachers + 4 students) from which a committee of 5 is to be formed. This can be done in 10C5 ways.
The number of ways that a committee can be formed with no students in it is to select 5 teachers out of the pool of 6 teachers available. This can be done in 6C5 ways.
Therefore the total number of ways that the committee can be formed with at least one student in it is 10C5 - 6C5.
10C5 = 252
6C5 = 6
Therefore the required number of ways = 246
