M/_A= 120°
m/_B=30°
m/_C= 100°
sum of all the angles=120+30+100 = 250°
Answer:
Decile
Step-by-step explanation:
Quartile only divides group into 4 => 25%, 50%, 75%, 100%
Decile divides group into 10 => 10%, 20%,..., 80%, 90%, 100%

Answer:
P(rolling a 1) = 1/6, 1 in 6, or 0.17
Step-by-step explanation:
When you toss a die, there are 6 possible outcomes: {1, 2, 3, 4, 5, 6}. All have the same probability: 1 in 6, or 0.17.
Thus, P(rolling a 1) = 1/6, 1 in 6, or 0.17.
Answer:
48
Step-by-step explanation:
The square pyramid has exactly the same four triangles.
In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.
Surface area of square pyramid =
Where we know that b = 4 and h = 6.
Substituting into the formula should give us the answer 48.
