Answer:
The solutions are correct
Step-by-step explanation:
i) In a year there is a total of 12 months, if ten students can have birthdays in 10 different months, the number of ways this can happen is:
Number of ways = 12 × 11 × 10 × . . . × 3 = 
ii) The number of ways 1 student can have birthday months = 12¹, The number of ways 2 students can have birthday months = 12¹ × 12¹ = 12². Hence:
The number of ways 10 students can have birthday months = 12¹⁰
iii) The probability that no two share a birthday month = 
= 0.00387
Answers:
16 chickens
35 pigs
========================================================
Explanation:
x = number of chickens
y = number of pigs
There are 51 heads, so x+y = 51 which solves to y = 51-x
2x = number of legs just from the chickens (2 legs per chicken)
4y = number of legs just from the pigs (4 legs per pig)
2x+4y = 172 legs total
----------
Plug in y = 51-x and solve for x.
2x+4y = 172
2x+4(51-x) = 172
2x+204-4x = 172
-2x+204 = 172
-2x = 172-204
-2x = -32
x = -32/(-2)
x = 16
Now use this to find y
y = 51-x
y = 51-16
y = 35
Since x = 16 and y = 35, this means there are <u>16 chickens</u> and <u>35 pigs</u>.
----------
Check:
x+y = 16+35 = 51 which works
2x+4y = 2*16+4*35 = 172 and that also works.
Both equations are confirmed.
Answer : y=-2x-6
Explanation :
use y2-y1/x2-x1 to find the slope which is -2 and then multiply the slope by one of the points to get the formula
