38 < x + 10
38 - 10 < x
x > 28
Answer:
a) The interval for those who want to go out earlier is between 43.008 and 46.592
b) The interval for those who want to go out later is between 47.9232 and 51.9168
Step-by-step explanation:
Given that:
Sample size (n) =128,
Margin of error (e) = ±4% =
a) The probability of those who wanted to get out earlier (p) = 35% = 0.35
The mean of the distribution (μ) = np = 128 * 0.35 = 44.8
The margin of error = ± 4% of 448 = 0.04 × 44.8 = ± 1.792
The interval = μ ± e = 44.8 ± 1.792 = (43.008, 46.592)
b) The probability of those who wanted to start school get out later (p) = 39% = 0.39
The mean of the distribution (μ) = np = 128 * 0.39 = 49.92
The margin of error = ± 4% of 448 = 0.04 × 49.92 = ± 1.9968
The interval = μ ± e = 44.8 ± 1.792 = (47.9232, 51.9168)
The way for those who want to go out earlier to win if the vote is counted is if those who do not have any opinion vote that they want to go earlier
Answer:
4x^2
Step-by-step explanation:
The greatest common factor of 12, 8, and 16 can be no larger than the smallest difference between these numbers, which is 4. 4 is a factor of each number, so is the GCF of them.
The exponent of the greatest common factor of x^4, x^3, and x^2 can be no larger than the smallest of these exponents, which is 2. So, the GCF of the variable portion of the terms is x^2.
The product of the coefficient GCF and the variable GCF is ...
... 4x^2
