4. A balloon is released from the top of a building. The graph shows the height of the balloon over time. What does the slope and y-intercept reveal about the situation?

A. The balloon starts at a height of 0 ft and rises at a rate of 10 ft.

B. The balloon starts at a height of 10 ft and rises at a rate of 0 ft.

C. The balloon starts at a height of 0 ft and rises at a rate of 100 ft.

I'm pretty sure the answer is letter B or letter C

Step-by-step explanation:

C. the balloon starts at a height of 0 ft and rises at a rate of 100 ft./p>

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
