A lovely beach resort is Data Island. Since it first became a popular tourist destination more than 80 years ago, the earliest vacation homes have been constructed just a few steps from the beach. You are a real estate agent for a company that deals in vacation rentals and sales in the Data Islands. A report was recently presented to you by one of the interns on the data science team. The age of a house affects its price, according to the linear regression model they have ran. But this is absurd because newer homes ought to be more valuable.
1. As the coefficient of Age is positive, so the older the house, the more price it is. Sig. (or p-value) = 0.000 which implies that the co-efficient of Age is significant.
2. This may be that the people who live there are reluctant to sell it, so they quote a higher price or the size of old houses are large or they may be located at prime location.
3. We would ask new interns to consider other independent variables for the regression equation like size of house, location, etc.

a jar contains 4 white chips, 5 purple chips, and 1 black chip. chips are selected randomly one at a time, and are not replaced. find the probability of getting the purple chip given the black chip?
Add all the chips together to find the total amount
4 + 5 + 1 = 10
Since there are 5 purple chips in a jar full of 10 chips, the probability is 5/10. If you need to simplify then the answer would be 1/2.

15 is a composite number.
What are all composite number?In basic Mathematics, the numbers that have more than two factors are known as composite numbers. For example, factors of 6 are 1, 2, 3 and 6. Thus, there are four factors in total, and 6 is a composite number. The first ten composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18. To understand better, have a look at the following examples.
Therefore, your answer is 15
A) how many prime numbers are multiples of 5? b) how many prime numbers are multiples of 8?.
Answers to both subparts are shown:
(A) Only 1 prime number is in the multiples of 5 which is number 5 itself.
(B) No prime numbers are in the multiples of 8.
What are prime numbers?Any natural number higher than 1 that is not the sum of two smaller natural numbers is referred to be a prime number.
A composite number is a natural number greater than one that is not prime.
For instance, the number 5 is prime because there are only two ways to write it as a product, 1 × 5 and 5 × 1.
(A) Prime numbers that are multiples of 5:
All numbers that come in the table of 5 are multiples of 5.
Only the number 5 is the number that comes in the table of 5 is a prime number.
As 5 is only divisible by 1 and 5 itself.
(B) Prime numbers that are multiples of 8:
All numbers that come in the table of 8 are multiples of 8.
No number that comes in the table of 8 is a prime number.
As all the numbers are divided by also as 8 is an even number.
Therefore, answers to both subparts are shown:
(A) Only 1 prime number is in the multiples of 5 which is number 5 itself.
(B) No prime numbers are in the multiples of 8.

Housing prices in a small town are normally distributed with a mean of $156,000
and a standard deviation of $8,000 . Use the empirical rule to complete the following statement. Approximately 99.7 % of housing prices are between a low price of$_______ and a high price of$_______
So the answer here is approximately 95% of housing prices are between a low price of $143000 and a high price of $171000.
What is meant by empirical rule?The empirical rule, also known as the three-sigma rule or 68-95-99.7 rule, is a statistical principle that asserts that, with a normal distribution, virtually all observed data will lie within three standard deviations (denoted by ) of the mean or average (denoted by ).
The empirical rule specifically states that 68% of observations will fall inside the first standard deviation, 95% will fall within the first two standard deviations, and 99.7% will fall within the first three standard deviations.
The Empirical Rule indicates that 99.7% of data that are seen to have a normal distribution fall within 3 standard deviations of the mean.
According to this criteria, 68% of the data falls within one standard deviation, 95% within two standard deviations, and 99.7% within three standard deviations of the mean.

A 99% confidence interval for the ratio of two population standard deviations (sigma_1/sigma_2) ranges from 1.06 to 2.22. Based on this confidence interval, we can conclude that sigma_1 is larger than sigma_2. (Option B).
A confidence interval (CI) refers to a range of estimates for an unknown parameter. A confidence interval for a standard deviation refers to the range of values that is likely to contain a population standard deviation with a certain level of confidence. In the given situation, when sigma 1 is divided by sigma 2, the result lies within the range from 1.06 to 2.22. When a number x is divided by number y, the result would be less than 1 if x < y, greater than 1 if x > y, and equal to 1 if x = y. Since the ratio of sigma 1 and sigma 2 is more than 1, sigma 1 is greater than sigma 2.

V= (4d^2 - 48d + 96) / (-36(d - 1)^2) will be the expression for the volume of the following prism when the dimensions of the prism are given.
What is meant by Volume of figures?The quantity of space a three-dimensional figure occupies is measured by its volume. It is determined by multiplying the object's length, breadth, and height, and is generally symbolized by the letter "V". For example, the volume of a cube with sides of length 3 units is 3 x 3 x 3 = 27 units.
The formula 4/3r3 may be used to determine a sphere's volume, where r is the sphere's radius. The area of the base times the height of the cylinder, or r2h, yields the volume of a cylinder.
It's important to remember that the volume of a three-dimensions figure varies depending on its shape and size.
How to solve?
V = (d - 2/3d - 9) * (4/d - 4) * (2d - 6/2d - 4)
V = (d - 2/3d - 9) * (4/d - 4) * (4d - 24/4d - 16)
V = ((d - 2)/(3d - 9)) * (4/d - 4) * (4d - 24/4d - 16)
V = ((d - 2)/(3d - 9)) * (4/(d - 4)) * (4d - 24/(4d - 16))
V = ((d - 2)/(3d - 9)) * (4/(d - 4)) * (4d - 24/(4d - 16))
= ((d - 2) * 4 * (4d - 24)) / ((3d - 9) * (d - 4) * (4d - 16))
= (4d^2 - 48d + 96) / (12d^2 - 48d^2 + 144d - 36)
= (4d^2 - 48d + 96) / (-36d^2 + 144d - 36)
= (4d^2 - 48d + 96) / (-36(d^2 - 4d + 1))
= (4d^2 - 48d + 96) / (-36(d - 1)(d - 1))
V= (4d^2 - 48d + 96) / (-36(d - 1)^2)

determine the force in each member of the space truss and state if the members are in tension or compression. hint: the support reaction at e acts along member eb. why?
An arrangement of bars joined at the ends to create a two- or three-dimensional structure is called a truss.
External forces and responses to those forces are thought to act only at the nodes and cause either tensile or compressive forces in the members.
A planar truss is a two-dimensional truss that has all of its members and forces in the same plane. A space truss is another name for a three-dimensional truss. A member is said to be in traction when it is being pulled or pushed. When a member is being pushed or pulled, it is said to be in compression, and when it is in tension.

Point A will lie at the point 15 on the number line.
What is dilation?Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape. A dilation should either stretch or shrink the original shape. This transformation is expressed by the term “scale factor.”
If point A is at 6 and it is dilated by the factor 5/2 which means extension then the new location of point A is 5/2 x 6 which is 15

What is a histogram?
A histogram is a statistical information display that uses rectangles to show the frequency of data items in equal-sized numerical intervals. The independent variable is plotted along the horizontal axis and the dependent variable is plotted along the vertical axis in the most common form of a histogram.
a) If the exam is quite easy, it is expected that the majority of the students score well on the test, and since most of the data is closer to the maximum value rather than the minimum, the histogram has a negatively skewed shape.
