If the cubes are die such that each face has numbers from 1 to 6. Rolling two of them, there are 6x6 or 36 ways in which they may be arranged. For their numbers to sum to 7, the numbers should be 1 and 6, 2 and 5, 2 and 6, 3 and 4, 3 and 5, 3 and 6, 4 and 3, 4 and 4, 4 and 5, 4 and 6, 5 and 2, 5 and 3, 5 and 4, 5 and 5, 5 and 6, 6 and 1, 6 and 2, 6 and 3, 6 and 4, 6 and 5, 6 and 6. All in all there are 21 out of 36 and the probability is equal to 7/12.
Assuming that the population follows an exponential function, the it will take the form:
y=a(bˣ)
where:
a=initial value
b=growth factor
x=time
thus plugging our values in the equation we get:
y=40000(1.1ˣ)
thus the population in 2011 when t=3 will be:
y=40000(1.1³)
y=53240
Answer:
Step-by-step explanation:
y = 2x
when x = 1
y = 2(1).....y = 2........so when x = 1, y = 2
when x = 2
y = 2(2)....y = 4 ......so when x = 2, y = 4
when x = 3
y = 2(3)....y = 6.......when x = 3, y = 6
when x = 4
y = 2(4).....y = 8.....when x = 4, y = 8
============================
y = 4x - 1
when x = -4
y = 4(-4) - 1.....y = -17.....so when x = -4, y = -17
when x= -3
y = 4(-3)- 1..... y = -13....so when x = -3, y = -13
when x = -2
y = 4(-2) - 1.....y = -9.....so when x = -2, y = -9
when x = -1
y = 4(-1) - 1....y = -5.....so when x = -1, y = -5
you can make the tables from this info...
your basically just subbing in ur value of x into the equation to find ur value of y
