Answer:
y = mx + b
-1 = 2/5(-3) + b
-1 = -6/5+b
-1 + 6/5 = -6/5 + 6/5 + b
1/5 = b
y = 2/5x + 1/5
Step-by-step explanation:
- write down the slope-intercept form formula
- identify your x and y of the point
- replace x and y by the point
- multiply m and x
- do addition to get b
- write down the equation by replacing m and b with their values
Answer:
The value is
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
![n = [ \frac{z * \sigma }{E} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7Bz%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%5E2)
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for 
![n = [ \frac{1.645 * 155 }{47} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7B1.645%20%2A%20%20155%20%7D%7B47%7D%20%5D%5E2)
=>
