Answer:
The length of the arc is 
centimeters.
Step-by-step explanation:
The length of an arc (
) with a given central angle is determined by the following expression:
Where:
- Radius, measured in centimeters.
- Central angle, measured in sexagesimal degrees.
Given that 
and 
, then:
The length of the arc is centimeters.

I'm not sure if this answer is correct, but I hope so.
Answer:
The value of x = -6
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that g(x) = 2 x + 4 and g (x ) = -8
⇒ Equating
2 x +4 = - 8
Subtracting '4' on both sides, we get
2 x + 4 - 4 = -8 -4
⇒ 2 x + 0 = -12
⇒ 2 x = -12
<u><em>Step(ii):-</em></u>
Dividing '2' on both sides, we get
x = -6
The value of x = -6
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
Answer:
B. the mean of city A is greater than the mean of city B
Step-by-step explanation:
Find mean by adding every number than dividing by the total of numbers added so...
97+98+96+98+99=488 and 488/5=97.6 which is higher than the mean of city B
