Answer:
The speed is 2 1/2 miles per hour.
Step-by-step explanation:
To determine the rate, divide the distance by the time taken.
5/8 mile ÷ 1/4 hour
Applying the copy dot flip method:
5/8 * 4/1
Gives us 5/2 miles per hour.
Which simplifies to 2 1/2 miles per hour.
If we evaluate the p-value against the given significance level, we can establish that we have sufficient grounds to dismiss the null hypothesis, indicating the true mean diverges from 634 at a significance level of 10%.
Option C is correct. Step-by-step explanation: We need to identify which options are equivalent to 7/3. By evaluating each option: Option A: 9/49 is incorrect as it cannot be further simplified to yield multiples adequate to match. Option B: 18/42 reduces to 3/7, which does not equal 7/3, hence, incorrect. Option C: 42/18 divides down to 7/3, marking it as the correct choice. Option D: 49/9 also cannot be simplified to produce valid multiples.
