Change in distance = 176.4 - 44.1 = 132.3
change in time = 6 - 3 = 3

The object travels 132.3 meters in 3 seconds

the speed is the ratio of the two values

speed = distance/time
speed = 132.3/3
speed = 44.1 meters per second

This is the average speed of the object from t = 3 to t = 6 seconds. This is equivalent to the slope of the straight line through the two points.

The answer is The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.`

Answer:

Step-by-step explanation:

In a study of the relationship between pet ownership and physical activity in older adults, 586 subjects reported that they owned a pet, while 1931 reported that they did not. Give a 98% confidence interval for the proportion of older adults in this population who are pet owners. Lower limit Incorrect: Your answer is incorrect. Upper limit

p ± z × (1 - p/n)

z = 98%

p = 586/1931

= 0.3034697048

n = 1931

Approximately = 0.3035

Confidence interval =

0.3035 + 2.326 × ( 1 - 0.3035/ 1931)
