Answer:
5 pounds of cream cheese
Step-by-step explanation:
2 1/2x2= 5
You have to multiplicate this number by 2.
Using the conditions for the binomial distribution, it is found that it is a binomial variable, thus, the correct option is:
Yes. All four conditions are met.
---------------------------------------
For a variable to be classified as binomial, four conditions have to be met.
- For each trial, there can be only two possible outcomes.
- There is a fixed number of trials.
- Trials are independent.
- In each trial, the probability of a success and a failure has to be the same.
In this problem, the random variable is the number of spelling errors, which is a binomial variable, as:
- There are 250 words, thus the number of trials is fixed.
- For each word, either there is a spelling error or not, thus two possible outcomes.
- The probability of a word being misspelled is independent of any other word, that is, the probability of an spelling error is the same.
Thus, the correct option is:
Yes. All four conditions are met.

Answer:
y = 4x + 57
Step-by-step explanation:
y = 4x + b
9 = 4(-12) + b
9 = -48 + b
57 = b
y = 4x + 57
