Data:
x: number of months
y: tree's height
Tipical grow: 0.22
Fifteen months into the observation, the tree was 20.5 feet tall: x=15 y=20.5ft (15,20.5)
In this case the slope (m) or rate of change is the tipical grow.
m=0.22
To find the line's slope-intercep equation you use the slope (m) and the given values of x and y (15 , 20.5) in the next formula to find the y-intercept (b):
Use the slope(m) and y-intercept (b) to write the equation:
B) To find the height of the tree after 29 months you substitute in the equation the x for 29 and evaluate to find the y:
C) In this case as you have the height and need to find the number of moths you substitute the y for 29.96feet and solve the equation for x, as follow:
Answer:
Step-by-step explanation:
A single die is rolled twice, we have to find the probability of rolling an odd number in first throw and a number greater than 3 in the second throw.
a) Rolling an Odd number in first throw
A die has total 6 possible outcomes, out of which 3 are odd numbers i.e. 1,3 and 5
So, total number of possible outcomes = 6
Total Favorable outcomes (Odd numbers) = 3
Probability is defined as the ratio of favorable outcomes to total number of outcomes. So,
The probability of rolling an odd number would be =
b) Rolling a number greater than 3 in second throw
Here again total possible outcomes = 6
Favorable outcomes (Numbers greater than 3 are 4, 5 and 6) = 3
So,
The probability of rolling a number greater than 3 =
These two events(rolls) are independent of each other, so the overall probability of both events occurring would be the product of individual probabilities.
So,
Probability of rolling an odd number the first time and a number greater than 3 the second time =
