Answer:
X=5
Step-by-step explanation:
-3x+8=-7
-3x=-15
X=5
Answer:
We can see that this is dependent probability. We can find dependent probability of happening event A then event B by multiplying probability of event A by probability of event B given that event A already happened.
Step-by-step explanation:
In our case event A is pirate hitting captain's ship and event B is captain missing pirate's ship. We have been given that pirate shoots first so pirate's ship can't be hit before pirate shoots his cannons. So probability of hitting captain's ship is 1/3. We have been given that if Captain Ben's ship is already hit then Captain Ben will always miss. So the probability of Captain missing the dread pirate's ship given the pirate Luis hitting the Captain ship is 1. Now to find probability that pirate hits Captain, but Captain misses we will multiply our both probabilities.
Answer:
The slope of the line m = 1
The equation of the straight line x -y -7=0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
In the given graph
The points are ( 7,0) and ( 0, -7)
The slope of the line
The equation of the straight line passing through the point (7,0) and slope m=1
y - y₁ = m (x - x₁)
y - 0 = 1( x-7)
y = x -7
x - y -7=0
<u><em>Final answer:-</em></u>
The slope of the line m = 1
The equation of the straight line x -y -7=0
<u><em></em></u>
Answer:
3/20
Step-by-step explanation:
Total number of students = 15 + 10 = 25
Number of girls = 10
Number of ways to select 2 students =
Number of ways to select 2 girls =
Compute the probability of selecting two girls as follows:
Thus, the probability that both students are girls is 0.15.
0.15 simplified in fraction from: 3/20
