Answer: b
its a 3.5 degree angle it is b
Answer and Step-by-step explanation:
For 2 dice, we have 36 possibles outcomes:
D₁ = {1,2,3,4,5,6}
D₂ = {1,2,3,4,5,6}
U = ({1,1};{1,2};{1,3};...;{2,1};{2,2};...;{6,6})
This way, it's 6 for D₁ and 6 for D₂, 6.6 = 36
The possible 3 that might appear when rolling a pair of dice would be
{1,2} and {2,1}, so, 2.
The probability of rolling 3 is 2/36 = 1/18
The formula for density = number/ area
In this case number=20
area = 5m^2
Density = 20/5=4 mice per m^2
The right answer is <span>A. 4 per m2</span>
Answer:
<u>Use the formula for area of the triangle:</u>
- A = 1/2bh, where b- base, h- height or altitude
<h3>Part A</h3>
<u>The triangle i has:</u>
<u>The area is:</u>
<h3>Part B</h3>
Triangles have same area as they are congruent.
<u>Total area is:</u>
