Answer:
The value is
Step-by-step explanation:
From the question we are told that
The probability of the device failing during the warranty period is 
The sample size is 
The random variable considered is x = 15
Generally this is distribution is binomial given the fact that there is only two out comes hence
X which is a variable representing a randomly selected selected electronic follows a binomial distribution i.e

Now the mean is mathematically evaluated as

=> 
=> 
The standard deviation is mathematically represented as

=> 
=> 
Now given that n is very large, then it mean that we can successfully apply normal approximation on this binomial distribution
So
Now applying Continuity Correction we have

Generally 

From the z-table

Thus
Answer:
500
Step-by-step explanation:
If 1% is 2.5 then 100% is 250. Since 250 is half of a number, you went then multiply by 2 to double that number which is 500.
Answer: C) Changing one or more properties of a sine wave in response to data.
Step-by-step explanation:
Modulation is primarily used in telecommunications sector. It the process by which data is transmitted via electrical signals. It is the process of imposing an input signal on to a wave carrier. It is the pillar of data communication that enables the use information carriers of signals that are electrical and optical. Altering the carrier/ periodic waveform results in Modulation. The amplitude frequency and phase are conveyed. There are different types of Modulation which includes: amplitude Modulation, frequency Modulation, and phase Modulation.
Answer:
AREA:

CIRCUMFERENCE:

Step-by-step explanation:
The formula that is used to calculate the area of a circle is:

Where "r" is the radius of the circle.
The formula for calculate the circumference of a circle is:

Where "r" is the radius of the circle.
Then, you need to find the radius. This is:

Substituting the radius, you get that the area and the circumference are:
AREA:

CIRCUMFERENCE:
