The further apart the objects are, the ___ the force of gravity

Answers

The Distance Between the Objects As distance between the objects increases, the force of gravity decreases.

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Katie hikes 5 miles north, 7 miles east, and
then 3 miles north again. What number of
miles, measured in a straight line, is Katie
from her starting point?
(A) 83
(B) 10
(C) 113
(D) 13

Answers

Answer:

B is the closest answer

Explanation:

It helps to draw it out to visualize on a grid. But to save time, she ends up traveling a total of 8 miles north and 7 miles east. These are the two legs of the right triangle. You are looking for the straight line she is from her starting point which is the hypotenuse. Use the Pythagorean Theorem, a^2+b^2=c^2

7^2+8^2=c^2

c= 10.63

The types of sampling errors that exist in the following sampling designs will be nonresponse, voluntary, and convenience.

For the first question, it should be noted that everyone cannot respond as only the people who have strong opinions will respond. Therefore, it's a nonresponse error.

For the second question, the people will have to volunteer. Therefore, it's a voluntary bias while the third one is a convenience sample as it's an easily available sample.

On San Martin Boulevard, embedded sensors kept track of the vehicle traffic count each hour for five weekdays, Monday through Friday, between 6 a.m. and 8 p.m. (5 weeks × 14 hours = 70 observations).

Answers

The question is incomplete. The complete question is below.

On San Martin Boulevard, embedded sensors kept track of the vehicle trafffic count each hour for five weekdays, Monday through Friday between 6am and 8pm. (5 weeks x 14 hours = 70 observations)

(a) Visually estimate the quartiles Q1, Q2, Q3.

(b) Estimate xmin and xmax.

Answer: (a) Q1 = 3300; Q2 = 3900; Q3 = 4300

(b) xmin = 2400; xmax = 4800

Explanation: The figure below shows a box-and-whisker plot: it is a graphical representation of the variation of data observed through quartiles and lines extending from the lowest and to the highest values.

Quartiles divides a list of numbers into 4 parts (quarters). There are 3 important quartiles:

Q1: the lower quartile. Represents the left edge of the box;Q2: the middle (median) quartile. Corresponds to the median of the set of numbers;Q3: the higher quartile. Represents the right edge of the box;

The boxplot also have its minimum and maximum, which is given by the lines (whiskers) of the plot.

Analysing the plot for the San Martin Boulevard:

(a) The lower quartile or Q1 is: Q1 ≈ 3300

The median quartile (Q2) is: Q2 ≈ 3900

The higher quartile (Q3) is: Q3 ≈ 4300

(b) The minimum value the data can assume is: xmin = 2400, while the maximum value is: xmax = 4800

(c) No, the distribution is not symmetric because Q2 is not in the middle of the box and the whisker to the left is longer than to the right. A boxplot is symmetric when median is located in the middle of the box and the whiskers are about the same side on both sides.

He should have less total loan to repay to the financial insitute or organization that loaned to him, as he made his first payment towards getting out of their debt.

A down payment is the initial payment back on a loan, usually provided up front, so it should reduce the amount required to pay back.
