Let's convert the given equation into slope - intercept form :

  • 2x + 5y =  - 20

  • 5y =   - 20 - 2x

  • y =  \dfrac{ - 20 - 2x}{5}

  • y =  \dfrac{ - 20}{5}  -  \dfrac{2x}{5}

  • y =  - 4 -  \dfrac{2x}{5}

  • y =  -  \dfrac{2}{5} x - 4

So, here y - intercept (c) = -4

According to the national institute of allergy and infectious diseases about 3.7% of american adults have a food allergy. A larg
bixtya [17]

Answer:

The mean of x is close to 14.8.

The standard deviation of x is close to 3.78.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and each trial can only have two outcomes, with probabilities \pi and 1 - \pi.

For an experiment with n repeated trials and a probability of success \pi, we have that:

The mean is: \mu_{x} = n*\pi

The standard deviation is: \sigma_{x} = \sqrt{n*\pi*(1-\pi)}

In this problem

There are 400 employees, each with a probability of 3.7% of having food allergy. So n = 400, \pi = 0.037. So:

\mu_{x} = n*\pi = 400*(0.037) = 14.8

The mean of x is close to 14.8.

\sigma_{x} = \sqrt{n*\pi*(1-\pi)} = \sqrt{400*(0.037)*(1-0.037)} = 3.78

The standard deviation of x is close to 3.78.
