Answer: either A,C or B
Step-by-step explanation:
Answer: y = {5, 4, 8}
<u>Step-by-step explanation:</u>
f(x) = 4 + x²
f(-1) = 4 + (-1)²
= 4 + 1
= 5
f(0) = 4 + (0)²
= 4 + 0
= 4
f(1) = 4 + (1)²
= 4 + 1
= 5
f(2) = 4 + (2)²
= 4 + 4
= 8
Answer:
no.
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.
