Karla is asked two questions: "Can a bat fly?" and "Is a bat a mammal?To which question will Karla respond more slowly, and why?

Result: 9000

Details:

10 automatic sprinklers are used for 10 minutes over 2 sessions each day.

Each sprinkler delivers 1.5 gallons of water per minute.

Question:

What is the total amount of water utilized by the neighbor during a 30-day billing period?

Resolution:

Each sprinkler dispenses water for 20 minutes daily (10*2). In that time, every sprinkler can provide (20*1.5) or 30 gallons. With 10 sprinklers, the total is (10*30) 300 gallons per day. Over 30 days, the total water usage amounts to (30*300)9000 gallons.

Answer:

(a) The athlete who finished first in the race had the quickest running time of 9.6 seconds

(b) There is a direct proportional relationship between reaction time and running time on average

(c) Long-term assumptions associated with least-squares regression

Limited efficacy in terms of sensitivity to outliers

Challenges in terms of extrapolating data characterizations

Explanation:

It is stated that

Total race time = Reaction time + Running Time

The winner is the athlete with the minimum total race time, which equates to the runner who has the lowest (Reaction time + Running Time)

Analyzing the scatter plot indicates that the winner corresponds to the lowest sum of x + y coordinates, placing the winner near the origin.

The three closest to the origin yielded the following x + y values:

0.135 + 9.7 = 9.835

0.145 + 9.7 = 9.845

0.153 + 9.6 = 9.753

Consequently, the athlete with the winning time was the one who achieved a running time of 9.6 seconds

(b) No, as a slight estimate indicates that an increase in running time correlates with an increase in reaction time

(c) Given a reaction time of 0.3 seconds is an outlier, employing a least-squares regression model may not be suitable due to the issues of extended range, limited sensitivity to outliers, and challenges in extrapolation characterization.

Answer:

See Explanation

Explanation:

The query lacks complete information because the value of s(t) is not provided;

Nonetheless, here is a useful guideline;

Let's proceed with the following assumption:

Required

Find the velocity at t = 8

To achieve this, first compute s(t) by inserting 8 for t in

Next, calculate the velocity by taking s(t) and dividing it by t when t = 8

i.e.

Insert 8 for t

Insert 72 for s(8)

In summary: calculate s(8) first, then divide that number by 8 to obtain your answer
