Answer:
Step-by-step explanation:
1. Cut six desired measures of string to properly wrap and tied around each end of the three sticks
2. Once fastened, bring two of the sticks together making one the bottom (base) and the other a side (angle).
3.Cut a tiny piece of rope to interlock with the rope you already have tied on the ends.
4.Tie the ends together with the new cut of string and make your desired angle as you tighten it.
5. Mirror Step 4 for the other end of the bottom stick (base), while most importantly mirroring the desired angle of step 4.
This should give you a proper equilateral triangle made out of sticks and string or anything of these two materials.
128 that is the answer yw
Answer:
The length of BC can be calculated by adding segment CD and DB. Thus the length of segment BC is . Find the total length by adding segment CD and DB. Substitute the value of to length of segment BC.

Answer:
0.36 = 36% probability that the land has oil and the test predicts it
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
45% chance that the land has oil.
This means that 
He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.
This means that 
What is the probability that the land has oil and the test predicts it?
This is . So
0.36 = 36% probability that the land has oil and the test predicts it
