Answer:
243 ways
Step-by-step explanation:
Calculating the number of posible outcomes:
We have n trials.
Each trial has m possible outcomes.
The total number of outcomes is:
In this question:
5 questions, that is, 5 trials, so 
Each question has 3 options(True, false or unanswered). So 
How many ways?
1. A.
None of the other answers, looking at the graph, make sense.
2. B.
Used distance formula.
sqrt[(0+8)^2 + (6-0)^2]
sqrt[8^2 + 6^2]
sqrt[64 + 36]
sqrt[100]
10
3. A.
Domain = x
(1,0) , (3,0) , (5,0) , (7,0)
Range = y
(0,2) , (0,4) , (0,6) , (0,2)
{(1,2) , (3,4) , (5,6) , (7,2)}
Answer:
<h3>
x = 10.0 </h3>
Step-by-step explanation:
tan(35°) ≈ 0.7002
from triangle:
tan(35°) = 7/x
so:
7/x = 0,7002
7 = 0.7002•x
x = 7/0.7002 = 9,9971...
x ≈ 10.0
Answer:
9/3
