Answer:
0.0079 = 0.79% probability that she randomly plants the trees so that all 5 sycamores are next to each other and all 5 palm trees are next to each other.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The trees are arranged, so, to find the number of outcomes, the arrangements formula is used.
Arrangements formula:
The number of possible arrangements of n elements is given by:

Desired outcomes:
5 sycamores(5! possible ways) and then the 5 palm trees(5! possible ways)
5 palm trees(5! possible ways) then the 5 sycamores(5! possible ways).

Total outcomes:
Arrangements of 10 plants, so:

What is the probability that she randomly plants the trees so that all 5 sycamores are next to each other and all 5 palm trees are next to each other?

0.0079 = 0.79% probability that she randomly plants the trees so that all 5 sycamores are next to each other and all 5 palm trees are next to each other.
He is correct. The pattern is -11,-11+15,+11 and +11
The area of a square is length^2
(5ab)² = (5ab)*(5ab) = 25a²b²
Answer:
108m²
Step-by-step explanation:
So we know to find the volume for a rectangular prism we need to multiply base * height * leght.
For this problem to make it a little easier we can seperate it into 2 rectangular prisms. and then add the volume of both after.
1st prism volume:
2 * 2 * 7 = 28cm²
2st prism volume:
5 * 2 * 8 = 80m²
Final prism volume:
28cm² + 80m² = 108m²
