Answer:
4x - 2
Step-by-step explanation:
The perimeter of a shape is when you add up all the sides.
-So, you can write it as: 2x - 5 + 5 - x + 3x - 2.
-Group the terms together to get: 2x + 3x - x - 5 + 5 - 2
-Combine like terms to get: 4x - 2
Hope this helps! :)
Answer:
A) 0.005
B) 0.001
C)0.0495
Step-by-step explanation:
Let A be the event that an aircraft is present and let B be the event the radar registers its presence.. Thus;
P(A) = Probability that an aircraft is present
P(A') = Probability that an aircraft is not present
P(B) = Probability that the radar generates an alarm
P(B') = Probability that the radar doesn't generate an alarm
Thus from what we are given, we have;
P(A) = 0.05
P(A') = 0.95
P(B) = 0.99
P(B') = 0.01
P(B|A') = 0.1
A) Probability of a false alarm will be;
P(A' ∩ B) = P(A) × P(B|A')
P(A' ∩ B) = 0.05 × 0.1 = 0.005
B) probability of missed detection is;
0.1 × (1 - 0.99) = 0.001
C) probability that an aircraft is present given that the radar registers a presence will be;
P(A ∩ B) = P(A) × P(B)
P(A ∩ B) = 0.05 × 0.99
P(A ∩ B) = 0.0495
Answer:
He needs 4 more pieces
Step-by-step explanation:
Here, we want to know the number of more string pieces that are needed
Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece
we divide 8 2/5 by 3/5
That will be;
42/5 * 5/3 = 14
So what he will get is 14 pieces from the 8 2/5 inch
The number of pieces needed is thus;
18-14 = 4

Answer:
x = -64
Step-by-step explanation:
Step 1: Write out equation
9 - 3/4x = 57
Step 2: Subtract 9 on both sides
-3/4x = 48
Step 3: Multiply both sides by -4/3
x = -64
