Answer:
Although the number 30 can be factored different ways, the result is always has one 2, one 3 and one 5. Every possible factor tree for the number 30 is shown below. The number 30 can be written in prime factorization as 3 x 3 x 5. All of the factors are prime numbers.
D'(-3,-4)
E'(-3,-10)
F'(3,-6)
Answer: Our required probability is
Step-by-step explanation:
Since we have given that
Number of red envelopes = 3
Number of blue envelopes = 3
Number of green envelopes = 1
We need to select 3 envelopes in such a way that at least one envelope is a red.
So, it becomes,
Hence, our required probability is
Answer:
Step-by-step explanation:
radius of semicircle =4.7/2 m
area of semicircle=1/2 πr²
=1/2 ×π×(4.7)²
≈8.67 m²
fertiliser=8.67×20
=173.4
≈173 gm
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.
