I think it is C but not for sure
Step-by-step explanation:
Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So, 
So, we can apply normal approximation.
Mean = 20
Standard deviation = 
Since 
So, Probability that fewer than 30 but a packet after testing a free sample is given by

Hence, our required probability is 0.99338.
Answer:
477,900
Step-by-step explanation:
One is a higher level the other is being payeda different amount
The correct answer is D. -7w and 3w.
Like terms are numbers that both either have the same variable or both have no variable.
A variable is an unknown number represented as a letter.
Since -7w and 3w both have the variable w, they are like terms.
Hope this helps!
