Step-by-step explanation:
We are given the expression of the equation of a circle that is
x2 + y2 + 14x + 2y + 14 = 0.
Using completing the squares:
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal to square root of 36 equal to 6.

Answers
We have,
Departing time = 10 : 45 hoursDistance between home and airport = 325 kmAverage speed = 50 km/hFinding time taken by the man,
⇛ Average speed = Total Distance/Total time
⇛ Total time = Total Distance/Average speed\(.\)
⇛ Total time = 325 km/50 km/h
⇛ Total time = 6.5 h (6 hrs 30 mins)
(a) Total Time duration,
⇛ Total Time = Reaching Time - Departing time
⇛ 6.5 h = Reaching Time - 10 : 45 hours
⇛ Reaching Time = 17 : 15 hours ( 5 : 15 pm)
(b) Finding time taken in return,
Departing time = 18 : 35 hoursReaching time = 23 : 10 hoursTotal time duration,
⇛ Total Time = Reaching Time - Departing time
⇛ Total Time = 23 : 10 hours - 18 : 35 hours

The quality department at ElectroTech is examining which of two microscope brands (Brand A or Brand B) to purchase. They have hired someone to inspect six circuit boards using both microscopes. Below are the results in terms of the number of defects (e.g., solder voids, misaligned components) found using each microscope. Use Table 2. Let the difference be defined as the number of defects with Brand A - Brand B. Specify the null and alternative hypotheses to test for differences in the defects found between the microscope brands. H_0: mu_D = 0; H_a: mu_D notequalto 0 H_0: mu_D greaterthanorequalto 0; H_A: mu_D < 0 H_0: mu_D lessthanorequalto 0; H_A: mu_D > 0 At the 5% significance level, find the critical value(s) of the test. What is the decision rule? (Negative values should be indicated by a minus sign. Round your answer to 3 decimal places.) Assuming that the difference in defects is normally distributed, calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Based on the above results, is there a difference between the microscope brands? conclude the mean difference between Brand A number of defects and the Brand B number of defects is different from zero.
Answers
Based on the above results, there is no difference between the microscope brands.
We are given that;
\(H_0: mu_D = 0; H_a: mu_D notequalto 0 H_0: mu_D greaterthanorequalto 0; H_A: mu_D < 0 H_0: mu_D lessthanorequalto 0; H_A: mu_D > 0\)
Now,
The null hypothesis is that the mean difference between Brand A number of defects and the Brand B number of defects is equal to zero. The alternative hypothesis is that the mean difference between Brand A number of defects and the Brand B number of defects is not equal to zero.
The decision rule for a two-tailed test at the 5% significance level is to reject the null hypothesis if the absolute value of the test statistic is greater than or equal to 2.571.
The value of the test statistic is -2.236. Since the absolute value of the test statistic is less than 2.571, we fail to reject the null hypothesis.
So, based on the above results, there is not enough evidence to conclude that there is a difference between the microscope brands.
Therefore, by Statistics the answer will be there is no difference between Brand A number of defects and the Brand B.

What is the relationship between fractions and decimals?
Fractions are ratios of two numbers. Often, these numbers are each whole numbers, such as 1/2 or 3/4. Fractions, however, can also be used to express ratios of partial numbers.
They are mostly used for portions that are easily broken apart.
On the other hand, Decimals are numbers that fall between integers and are described as digits following a decimal point.
Decimals use a system of numbers based on units of tens, which results in the spaces past the decimal point as tenths, hundredths, thousandths and so on.
Relationship between Fractions and Decimals:
Fractions and decimals are similar because they both are ways to express partial numbers. Additionally, fractions can be expressed as decimals by performing the division of the ratio.
(For example, 3/4 is equivalent to 3 divided by 4, or 0.75.) Decimals can also be expressed as fractions in terms of tenths, hundredths, thousandths, and so on.
(For example, 0.327 is equivalent to 327 thousandths, which is equivalent to 327/1,000.)

14. Three points tat are not collinear
Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane
15. A line and a point not lying on the line
Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface
16. Two lines which intersect at a point
Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane
Step-by-step explanation:

WHAT IS THE EQUATION OF THE GRAPH?
Answers
Problem 1 (on the left)
It appears we have an exponential function curve through the points (0,4) and (1,7)
The general exponential function is of the form
y = a*b^x
The value of 'a' is the y intercept or initial value. So a = 4
Plug in (x,y) = (1,7) to help solve for b
y = a*b^x
y = 4*b^x
7 = 4*b^1
7 = 4b
b = 7/4 = 1.75
Therefore, the function is y = 4*(1.75)^x
Plug in x = 0 and you should get y = 4. Plug in x = 1 and you should get y = 7These two facts help confirm we have the correct exponential equation.
Answer: y = 4*(1.75)^x===========================================================
Problem 2 (on the right)
The steps will follow the same idea as the previous question.
The exponential curve goes through (-1, 120) and (0,40)
We have a = 40 this time due to the y intercept (0,40)
Plug in the coordinates of the other point to find b
y = a*b^x
y = 40*b^x
120 = 40*b^(-1)
120 = 40/b
120b = 40
b = 40/120
b = 1/3
Answer: y = 40*(1/3)^xBased on past experience, a bank believes that 8% of the people who receive loans will make payments on time. The bank has recently approved 600 loans.

Answers
The sampling distribution model for figuring out how many people in this group might not pay on time is:
E. mean = 8%; standard deviation = 1.1%.
Sampling Distribution Model MeanThe steps to determine the mean and standard deviation of the sampling distribution of the proportion of clients who may not make timely payments would be:
Start with the idea that 8% of the loans will have payments that are late. So the percentage of people who pay late is p = 0.08.
Calculate the sample size, which is given as n = 600.
Determine the mean of the sampling distribution. The mean of the sampling distribution of the proportion of late payments is equal to the population proportion, which is 0.08.
Find the standard deviation of the distribution of the samples. The standard deviation is discovered by taking the square root of the commodity of the sample size and the percentage of late payments in the whole population (1 - percentage of late payments in the whole population) and dividing it by the sample size:
σ = √( (p * (1-p)) / n )
Substituting the values for p and n, we get:σ = √( (0.08 * 0.92) / 600 ) ≈ 0.011
So the standard deviation of the sampling distribution is approximately 0.011, or 1.1%.So, the answer will be option E. mean = 8%; standard deviation = 1.1%.
