Answer:
Figure out the x and y intercepts.
Step-by-step explanation:
you should find what the y or x intercept's are.
To figure that out you need to divide the number next to x or y to 8. use x to find out x intercept and y for y intercept.
lets find out y intercept
8 / -2 = -4
and now x intercept
8 / 3 = 1.75 or 1 (3/4)
Once you found out the intercepts you can now graph the equation.
Answer
Step-by-step explanation find the roots of the equation by solving for x
Answer:
one third or 0.333333...
Step-by-step explanation:
a rational number is a number that can be written as a ratio between two numbers. they an be repeating like 1/3 or terminating like 1.36.
Answer:
a. 250 fields
b. 220 to 280 fields
c. Fields are not independent
Step-by-step explanation:
a. The average number of fields sampled that are infested with whitefly =
number of fields X Percentage sampled, 10%
= 2500 X 10% = 250 fields
b. Going by the binomial distribution is the square of the standard deviation, divided by (the product of the sample size n, and the probability a and b). While the standard deviation is the square root of the variance
σ = √nab
= √na(1-a) = √2500 X 10% X (1- 10%)
= √225 = 15
Now let's use the empirical rule that says about 95% of the observations are within two standard deviations from the mean since the number of trials is very large
μ - 2σ = 250 - 2(15) = 220
μ + 2σ = 250 + 2(15) = 280
Approximately 220 to 280 fields are expected to be infested going by 95% probability observation
c. Since x=25 is considered small and is not captured within 220 and 280 fields making one of the characteristics of binomial experiment not satisfied which expects each field to be independent. Making fields that are close together more likely to be infected.
