Step-by-step explanation:
Answer:
Chris is correct. (Choice letter C)
Step-by-step explanation:
We can eliminate choices A and B from the get-go because the problem stated that both hikers are traveling at 1mi/hr. This means that the slope of the equation would equate to 1, so just x.
That leaves us with C and D. The two equations both have a slope of 1, but C has a y-intercept of -2 and D has a y-intercept of 2, which represents the starting location of the second hiker. The first hiker is the one who is ahead by 2 miles, so it can't be D. This leaves us with choice C. Chris is correct.
I think its 11 for its absolute value
Answer:
Step-by-step explanation:
Given mean = 84,
Standard deviation = 2,
Sample 64,
95% confidence interval: z = 1.96
Applying empirical rule , means that 95% of data fall within two standard deviations.
ME = = 0.49
Rounding this to 0.5
CI = 83.5< mean < 84.5
Outside of this range= x ≤ 83.5 and ≥ 84.5
