Answer:
0.595
Step-by-step explanation:
We are given that An archer hits centre of the target
We have to calculate the probability that she will hit the centre of the target on two consecutive shots.
P(A)=P(B)=0.70
P(B/A)=0.85
We know tha formula
Substitute the value then we get
Hence, the probability that she will hit the centre of the target on two consecutive shots=0.595
Answer:
<h2>16.6 ft</h2>Step-by-step explanation:
The height of the house, the ground and the ladder forms a right angle triangle, with the following parameters stated below.
1. the hypotenuse is the length of the ladder which is 30 feet
2.the opposite is the height of the house, which is 25 feet
3. the adjacent is the distance of the ladder away from the building, this is the parameter we are solving for.
Since we have two sides of the triangle given, we can employ Pythagoras theorem to solve for the third side of the triangle
let the the opposite be x
we know that
Solving for x we have
Hence the maximum distance away from house that he can place
the ladder is 16.6 ft to the nearest foot
