Answer:
a. P) = 0.25
b. P) = 0.25
c. P) = 0.5
Step-by-step explanation:
a) 1/4 as 1/2 x 1/2 = 1/4 = 0.25 This becomes reduced as we are multiplying one complete probability journey by another complete probability journey.
b) see above as 1/2 x 1/4 and 1/4 x 1/2 = 2.5 = 1/4 = 0.25
or we can Set to 1 and 1 - 3/4 = 1/4. = 0.25.
c) 1/2 as half of the journeys have traffic jams so its 1 - 1/2 = 1/2 = 0.5
Answer:
1. 1+4 = 5in^2
2. 1+6 = 7cm^2
3. 8+4 = 12ft^2
4. 2(3) = 6m^2
5. 16+8 = 24yd^2
6. 5 + 10 = 15mi^2
Step-by-step explanation:
Each problem can be solved by just adding the areas of the individual simple shapes such as triangle and parallelogram.
Area of trigangle = *b*h
Area of parallelogram = b*h
As a decimal it would be 0.333..
Answer:
52,53,54
Step-by-step explanation:
x, x+1, x+2
2x+1=x+53
x+1=53
x=52
x+1=53
x+2=54
Answer:
Step-by-step explanation:
Since, According to the question,
Total mice die in 1991 = 8064483601014110592
Total changes in the population of mice in 1991 = 2.946495792e 19
Since,
The total changes in the population of the mice in 1991= difference between the population of total mice born and the total mice die.
⇒ 2.946495792e 19 = total mice born on 1991 - 8064483601014110592
⇒ total mice born on 1991 = 2.946495792e 19 + 8064483601014110592
⇒ total mice born on 1991 = 3.7529442e+19
Thus, On 1991 mice were born.
Note: Here, we assume that the mice born is more than mice dying because the population of mice is increasing every year exponentially.
