Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98

The probability of system failure is 1-(probability of success)= 1-0.98= 0.02

How is the data represented on a scatterplot that depicts an exponential model?
Anastasy [175]
The choices can be found elsewhere and as follows:

<span>a. points on a line 
b. random points
</span>c. points on a horizontal line <span>
d. points on a curvy line

I believe the correct answer is option D. The </span><span>data represented on a scatterplot that depicts an exponential model would be points on a curvy line. Hope this answers the question. Have a nice day.</span>

Salinas planting a circular flower bed radius of 3 1/2 feet she plans Chase around it with wire fencing that cost 0.89 $ a foot
Brut [27]

Answer:

Total Fencing Cost =$19.57

Step-by-step explanation:

If Rosalina is planning on fencing, we are talking about the Perimeter of the Flower Bed

Perimeter of a Circle = 2\pi r

Radius of the circular flower bed =3.5 ft

Perimeter = 2\pi X 3.5=21.99ft

If Wire fencing Cost $0.89 per foot

Total Fencing Cost = $0.89 X 21.99=$19.57

Given that the population proportion is 0.82, the Normal distribution will provide a good approximation to the true sampling dis
Drupady [299]

Answer:

Then solution as long as n ≥ 56

Step-by-step explanation:

The Normal distribution will provide a good approximation to evaluate proportion tests when the following conditions are met:

n*p₀ > 10

n*q₀ > 10

As  p₀ = 0,82      q₀ = 0,18       n  = 13      30     56    and  100

We test:

A) n = 13        n*q₀  =  13*0,18 = 2,34       2,34 < 10  

B) n = 30       n*q₀  =  30*0,18 = 5,4         5,4 < 10

C) n = 56       n*q₀  =  56 * 0,18 = 10,08

                      n*p₀  = 56 * 0,82 = 45,92

D) n = 100      n*q₀  = 18

                      n*p₀  = 82

If we test 55  we find that  55*0,18  =  9,9

Then solution as long as n ≥ 56
