Consider the following portion of an electric circuit with three relays. Current will flow from point a to point b if there is at least one closed path when the relays are activated. The relays may malfunction and not close when activated. Suppose that the relays act independently of one another and close properly when activated, with a probability of .9. Given that current flowed when the relays were activated, what is the probability that relay 1 functioned?
Answer:
0.9009
Step-by-step explanation:
Let X be the event that Current will flow
Let Y be the event that the first relay which is 1 is closed
Thus, we can say that every element of Y is in X, but X possesses more elements. Thus, Y ⊂ X.
Thus, we can say that;
P(X ∩ Y) = P(Y)
Thus, given that current flowed, the probability that relay 1 functioned will be expressed as;
P(Y | X) = (P(Y ∩ X))/P(X)
From earlier, we saw that P(X ∩ Y) = P(Y). Thus;
P(Y | X) = P(Y)/P(X)
From the question, P(Y) = 0.9
Since there are 3 relays, then we have;
P(X) = 1 - 0.1³ = 0.999
Thus;
P(Y | X) = 0.9/0.999
P(Y | X) = 0.9009
The probability that relay 1 functioned is 0.9009
Calculation:
Let us assume X be the event that Current will flow
And,
Let us assume Y be the event that the first relay
So, Thus, Y ⊂ X.
Now
P(X ∩ Y) = P(Y)
The probability that relay 1 functioned should be
P(Y | X) = (P(Y ∩ X)) ÷ P(X)
From earlier, we saw that P(X ∩ Y) = P(Y).
So,
P(Y | X) = P(Y) ÷ P(X)
Now
P(X) =[tex]1 - 0.1^3[/tex] = 0.999
So,
P(Y | X) = 0.9 ÷0.999
P(Y | X) = 0.9009

Step-by-step explanation:
The curve y=ax2+bx+c passes through (2,5) (3,12) and (-1,-4).find the equation of the curve
Explanation:
You want to first to substitute to form 3 equations.
5=4a+2b+c
12=9a+3b+c
-4=a-b+c
Now solve with whatever way you fell comfortable, I'm going to use elimination.
First eliminate c
7=5a+b
16=8a+4b --> 4=2a+b
Then I'll eliminate b,
3=3a
a=1
Now solve for b and c
7=5+b
b=2
1-2+c=-4
c=-3
Now for the equation:
y=x^2+2b-3

Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form. P(-4,-9); m= -3/4
Answer:
4y = -3x - 48
Step-by-step explanation:
y - y1 = m(x - x1)
y1 = -9 x1= -4 m = -3/4
y -(-9) = -3/4(x -(-4)
y + 9 = -3/4(x + 4)
y + 9 = -3/4x -12/4
multiply through by 4
4y + 36 = -3x -12
4y = -3x -12-36
4y = -3x -48 in the form y = mx + c

Answer/Step-by-step explanation:
Recall the acronym SOHCAHTOA. This is what we would apply as appropriate in each case.
8. θ = 40°
Opp = m
Adj = 20
Thus, apply TOA
Tan (θ) = opp/adj
Plug in the values
Tan (40) = m/20 (equation)
20×Tan(40) = m
m = 16.7820
9. θ = 22°
Hyp = w
Adj = 18
Thus, apply CAH
Cos (θ) = adj/hyp
Plug in the values
Cos 22 = 18/w (equation)
w×cos 22 = 18
w = 18/(cos 22)
w = 19.4136
10. θ = 35°
Hyp = 55
Opp = x
Thus, apply SOH
Sin θ = opp/hyp
Plug in the values
Sin 35 = x/55 (equation)
55×sin 35 = x
x = 31.5467
11. θ = 33°
Hyp = 19
Adj = x
Thus, apply CAH
Cos θ = adj/hyp
Plug in the values
Cos 33 = x/19 (equation)
19×cos 33 = x
x = 15.9347
12. θ = 17°
Opp = 7
Hyp = x
Thus, apply SOH
Sin θ = opp/hyp
Plug in the values
Sin 17 = 7/x (equation)
x×sin 17 = 7
x = 7/(sin 17)
x = 23.9421
13. θ = 40°
Opp = 15
Adj = x
Thus, apply TOA
Tan θ = opp/adj
Plug in the values
Tan 40 = 15/x (equation)
x×Tan 40 = 15
x = 15/(Tan 40)
x = 17.8763
2(a - 4) + 15 = 13

Answer:
VW = 43.2
Step-by-step explanation:
First, we can see that VZ = 88 - 55 = 33.
Then by the Triangle Proportionality Theorem, we can write that:
[tex]\displaystyle \frac{55}{33}=\frac{72}{VW}[/tex]
Simplify:
[tex]\displaystyle \frac{5}{3}=\frac{72}{VW}[/tex]
Cross-multiply:
[tex]216=5VW[/tex]
So:
[tex]\displaystyle V=\frac{216}{5}=43.2[/tex]

What is the value of x?
i need help with this problem down below
Answer:
[tex] y = 4 [/tex]
Step-by-step explanation:
Given:
[tex] y = \frac{7x + 1}{3x - 6} [/tex],
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into [tex] y = \frac{7x + 1}{3x - 6} [/tex]
[tex] y = \frac{7(5) + 1}{3(5) - 6} [/tex]
[tex] y = \frac{35 + 1}{15 - 6} [/tex]
[tex] y = \frac{36}{9} [/tex]
[tex] y = 4 [/tex]
The ratio of Mollie’s age to Heather’s age is 4:9 Heather is 40 years older than Mollie
How old is Mollie?
Answer:
I believe it would be 90
Step-by-step explanation:
The required age of Mollie's is 32years and age of Heather's is 72years.
Given that,
The ratio of Mollie’s age to Heather’s age is 4:9,
Heather is 40 years older than Mollie.
We have to determine,
How old is Mollie.
According to the question,
The ratio of Mollie’s age to Heather’s age is 4:9,
The age of Mollie's = 4x
And age of Heather's = 9x
Then ,
The age of Mollie is calculated in the following steps.
The difference between the age of both is 40 years
Age of Heather's - Age of Mollie = Difference of their ages
Then,
[tex]= 9x-4x = 40\\\\= 5x = 40\\\\= x = \frac{40}{5} \\\\= x = 8[/tex]
The value of x is 8.
Therefore,
Age of Mollie's = 4x = (4).(8) = 32years
And Age of Heather's = 9x = (9).(8) = 72years
Hence, The required age of Mollie's is 32years and age of Heather's is 72years.

A manufacturing firm just received a shipment of 18 assembly parts, of slightly varied sizes, from a vendor. The manager knows that there are only 16 parts in the shipment that would be suitable. He examines these parts one at a time. a. Find the probability that the first part is suitable. (Round your answer to 2 decimal places.) b. If the first part is suitable, find the probability that the second part is also suitable. (Round your answer to 4 decimal places.) c. If the first part is suitable, find the probability that the second part is not suitable. (Round your answer to 4 decimal places.)
Answer:
(a) 0.89
(b) 0.8823
(c) 0.1176
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Total number of parts = 18
Total number of suitable parts = 16
(a). Probability for the first part is suitable are as follows,
Here, favourable outcomes = 16
So, P1 = favourable outcomes ÷ Total number of parts
= 16 ÷ 18
= 0.89
(b). Probability for the second part is suitable are as follows,
Here, favourable outcomes = 16 - 1 = 15
total number of parts = 18 - 1 = 17
So, P2 = favourable outcomes ÷ Total number of parts
= 15 ÷ 17
= 0.8823
(c). Probability for the second part is not suitable are as follows,
Here, favourable outcomes = 17 - 15 = 2
Total number of parts = 17
So, P2 = favourable outcomes ÷ Total number of parts
= 2 ÷ 17
= 0.1176
