Answer:
Step-by-step explanation:
sin = opposite / hypotenuse
- sin 63° = 18/x
- x = 18 / sin 63°
- x = 20.2
Answer:
a) 28
Step-by-step explanation:
1 + 5 = 6
3 + 3 = 6
3 + 47 = 50
7 + 43 = 50
13 + 37 = 50
19 + 31 = 50
Probability of randomly rolling a 3 is 1/4
Step-by-step explanation:
Step 1:
It is given that a tetrahedron has 4 sides with 1,2,3 and 4 and is randomly rolled. We need to compute the probability of randomly rolling a 3.
Step 2:
Probability of an event = (Favorable outcomes) / (Total outcomes).
There are 4 total outcomes when the tetrahedron is rolled, these are the values 1 to 4.
The only favorable outcome is getting a 3
Probability of getting a 3 when the tetrahedron is randomly rolled = 1/4
Step 3:
Answer:
Probability of randomly rolling a 3 is 1/4
This in standard form is -28x + 10.
