Step-by-step explanation:</h3>
Given sentence:
- 2.4 pounds of peas cost $1.68.
<u>Writing as an equation:</u>
To obtain the cost per pound of peas, divide 2.4 both sides. This will convert the value on the L.H.S to <u>1 pound.</u> The value obtained on the R.H.S will be the the cost (answer).
Sample proportion: 190/425 = 0.45
ME = 1.96*sqrt[0.45*0.55/425] = 0.047
-----
95% CI: 0.45-0.047 < p < 0.45+0.047
Answer: a = 11.1
<u>Step-by-step explanation:</u>
a(0.3 - y) + 1.1 + 2.4x = 0
Let y = 1.3 → a(0.3 - 1.3) + 1.1 + 2.4x = 0 → -a + 1.1 + 2.4x = 0 → a = 1.1 + 2.4x
(y - 1.2) = -1.2(x - 0.5)
Let y = 1.3 → (1.3 - 1.2) = -1.2(x - 0.5) → 0.1 = -1.2x + 0.6 → -0.5 = -1.2x → 
a = 1.1 + 2.4x
= 1.1 + 0.4(25)
= 1.1 + 10
= 11.1
1. No, because every prime factor can not be prime factorized again. It could have more factorizations, but at least one of the factors would be a composite number which is the product of at least two of the prime factors.
2. Prime numbers and 1 do not have their prime factorization.
