77.47%
Step-by-step explanation:
We have to use Bayes Theorem in solving this problem.
This theorem's formula is:
P(A | B) = 
Where the " | " means <u><em>"given that"</em></u>.
For our problem, using bayes theorem, we can write:
P(Student has lice | positive ) = 
- P(Positive) = 0.1692 + 0.0492 = 0.2184
- P (Student has Lice & Positive ) = 0.1692
So P(Student has lice | Positive ) = 
Answer:
Total weight is 150 kg
Step-by-step explanation:
Firstly, we need the weight of the diagonal
To get this, we shall use the Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
The diagonals stand for the hypotenuse
Thus, we have that;
d^2 = 5^2 + 12^2
d^2 = 25 + 144
d^2 = 169
d^2 = 13^2
d = 13
The 6 sides technically includes the whole rectangle sides, then the two diagonals
The total length here is;
2(5 + 12 + 13) = 60 meters
Steel weight is 2.5 kg per meter
Weight of 60 m will be ;
60 * 2.5 = 150 kg
2r-3.1=1.7 add 3.1
2r=1.7+3.1 divide by 2 to isolate r
2r/2=4.8/2
r=2.4
check
2(2.4)-3.1=1.7
4.8-3.1=1.7
1.7=1.7
4t+3.5=12.5 sub 3.5
4t=12.5-3.5 divide by 4
4t/4=9/4
t=9/4
check
4(9/4)+3.5=12.5
9+3.5=12.5
12.5=12.5
8m-5.5=10.1 add 5.5
8m=10.1+5.5 divide by 8
8m/8=15.6/8
m=1.95
check
8(1.95)-5.5=10.1
15.6-5.5=10.1
10.1=10.1
Answer:
A= 29
B=34
C=117
Step-by-step explanation:
<u>A triangle has three sides and a triangle always adds up to be 180</u>
A + B + C = 180
B = A + 5
C = 4A + 1
Plug in.
A + A + 5 + 4A + 1 = 180
6A + 6 = 180
6A = 174
A = 29
<u>Now since you found A, find the other two by plugging A in!</u>
C = 4(29) + 1
C = 117
<u>Plug in the B equation</u>
B = 29 + 5
B=34
Check your answers
29 + 117 + 34 = 180
