Answer:
3) One-sided, compare two populations
Step-by-step explanation:
A manufacturer intends to evaluate if there is an improvement in the average gas mileage among mid-sized sedans that use a new type of tire, in comparison to those that do not utilize this tire type.
Thus, we have two distinct populations:
Population 1: Mid-sized sedans equipped with the new tire.
Population 2: Mid-sized sedans without the new tire.
Consequently, a comparison is being made between these two populations.
Furthermore, the manufacturer aims to determine if there is an enhancement in average gas mileage. As such, the alternative hypothesis will be right-tailed, indicating it is a one-sided test.
<span>This is quite challenging, but here’s the solution:
</span>
y = x^2 - 10x + 25 - 25
<span> y = (x-5)^2 - 25</span>
<span> y + 25 = (x-5)^2</span>
<span> x - 5 = ±sqrt(y+25)</span>
<span> You will derive TWO inverses:</span>
<span> x = 5 + sqrt(y+25),</span> for x ≥ 5
<span> x = 5 - sqrt(y+25),</span> for x ≤ 5

Step-by-step explanation:
1. Convert 1/4 into eighths to be able to subtract it from 5/8.
1/4 x 2 = 2/8
2. Deduct 2/8 from 5/8.
5/8 - 2/8 = 3/8
Daniel consumed 2/8 of the remaining pie, and now there are 3/8 left.
The condition of poor roads can indeed have significant repercussions on numerous aspects such as physical health, emotional well-being, and economic stability for families, communities, and the nation. Dangerous roads can lead to accidents, affecting individuals physically. The stress of navigating damaged roads can cause mental strain. Economically, poor road conditions can lead to increased prices for goods, as it takes more time to transport them by road. Additionally, transport costs can rise significantly.
