The first thing to do is to clear the equation of fractions by multiplying by its LCM, which is 6 in this case. When you do that, you will get the equation
4p + 36 = 7p. Much easier to deal with, right? Now move the 4p over by subrtracting it: 36 = 3p, and p = 12
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is
The sample size is n = 25
The combined resistance is 
Generally the sample mean is mathematically represented as

=> 
=> 
Generally the standard error of the mean is mathematically represented as

=> 
=> 
Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as



From the z table the area under the normal curve to the left corresponding to 1 is


No it’s not that’s the wrong answer
