Answer:
slope (m) = -50 or -50x
Step-by-step Explanation
I'm assuming that the x-axis is divided by 1 minute segments.
The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"
Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute
Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for
Answer: 1.509
Step-by-step explanation:
The formula of Margin of Error for (n<30):-

Given : Sample size : n= 22
Level of confidence = 0.99
Significance level : 
Using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error for a 99% confidence interval for the population mean =1.509
sooooooo....whats the question???

Answer:
1.003 * 10^8
Step-by-step explanation:
Given that :
The United States has about 100,300,000 registered to use cellular phones in the year 2000
100,300,000 in scientific notation:
(100,000,000) + (300,000)
(1 * 10^8) + (3 * 10^5)
To ensure equal power :
300,000 = 3 * 10^5 = 0.003 * 10^8
Hence,
(1 * 10^8) + (0.003 * 10^8)
(1 + 0.003) * 10^8
1.003 * 10^8
