i = (100m)/c
lowest i = 80, highest i = 120
c = 12
this will result in 2 equations, one will be the lowest (solving m when i = 80), and the highest (solving m when i = 120)
solve m when i = 80:
i = (100m)/c
80 = (100m)/12
80×12 = 100m
960 = 100m
960/100 = m
9.6 = m
solve m when i = 120:
i = (100m)/c
120 = (100m)/12
120×12 = 100m
1440 = 100m
1440/100 = m
14.4 = m
therefore,
Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.
Answer:17/12
Step-by-step explanation:2/3 + 3/4 = 2 · 4/3 · 4 + 3 · 3/4 · 3 = 8/12 + 9/12
= 8 + 9/12= 17/12
Answer:
the ecuation is 4+2x=16, and x is the number of years the tree needs to grow to a height of 16 ft
