Answer:
9 inches
Step-by-step explanation:
A foot is 12 inches long. To find a fourth of a foot, divide 12 by four to get 3. This means that Julio has already dug a hole one foot and three inches deep. To make his hole two feet deep, he will need to dig the other 3/4 of the foot. To find 3/4 of a foot, take 1/4 of a foot (3 inches) and multiply by 3 (9 inches).
Julio will have to dig 9 more inches.

The average rate of change of each function on the interval 2 ≤ x ≤ 6 is given as follows:
f(x): -1.25.g(x): -0.715.How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For the function f(x), we have that:
When x = 2, y = 7.When x = 6, y = 2.Hence the rate is given as follows:
r = (2 - 7)/(6 - 2)
r = -5/4
r = -1.25.
For the function g(x), we have that:
When x = 2, y = 2(-5/7) - 6 = -7.43.When x = 6, y = 6(-5/7) - 6 = -10.29.Hence the rate is given as follows:
r = (-10.29 - (-7.43))/(6 - 2)
r = -0.715

By z-test the test static is 1.25.
What is z-test?
It is a statistical test to determine whether two population means are different at the time when the variances are known and the sample size is large. Also it is a hypothesis test in which the z-statistic maintains a normal distribution.
A random sample of 100 people was taken. Eighty-five of the people in the sample favored Candidate A. We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 80%.
So from the given information we have,
sample size (n)= 100
sample proportion ( p₁) = 0.85 [ 85 of the people in the sample favored candidate A]
So, the null hypothesis ,
H₀ : p = 0.80
The alternative hypothesis ,
Hₐ : p > 0.80
Now the test static can be determined by the formula of z-test
[tex]z= \frac{p_{1} - p }{\sqrt{\frac{p(1-p)}{n} } }[/tex]
[tex]z= \frac{0.85 - 0.80 }{\sqrt{\frac{0.80(1-0.80)}{100} } }[/tex]
[tex]z= \frac{0.05}{\sqrt{\frac{0.16}{100} } }[/tex]
z = (0.05× 10)/0.4
z= 1.25

99.57 units is the measurement of the hypotenuse for the given triangle.
In this case, the legs of the triangle are 7x+6 and 5x, so we have:
a = 7x+6
b = 5x
Substituting x = 11, we get:
a = 7(11) + 6 = 83
b = 5(11) = 55
Now we can use the Pythagorean theorem to find the length of the hypotenuse:
[tex]c^2 = a^2 + b^2\\c^2 = 83^2 + 55^2\\c^2 = 6889 + 3025\\c^2 = 9914[/tex]
Taking the square root of both sides, we get:
c = √9914 ≈ 99.57
Therefore, the length of the hypotenuse of the triangle is approximately 99.57 units.

Yesterday, the track coach at Milton Middle School had the runners jog 3 times around the track for every 1 time they sprinted around it.
If the runners jogged 6 more laps than they sprinted, how many laps did they run altogether?
Therefore , the solution of the given problem of unitary method comes out to be the athletes completed a total of 12 laps.
What is an unitary method ?Finish the project using the tried-and-true basic methodology, the actual variables, and any pertinent knowledge you gain from the broad and specific questions. In response, customers might be given another opportunity to sample expression the products. We'll miss out on important breakthroughs in programming comprehension if these changes don't take place.
Here,
In accordance with the information provided, for each sprint around the track, the runners jogged three times. So, three times as many laps are jogged around the track.
Furthermore, it is known that the runners jogged six more laps than they ran. Therefore, we can construct the following equation:
Jogging laps equals sprinting laps plus six.
=> 3x = x + 6
=> 3x - x = 6
=> 2x = 6
=> x = 6/2
=> x = 3
Total laps equal 3x + x = 4x times the amount of jogged and sprinting laps.
By changing the value of x, we obtain:
Laps completed = 4 (3) = 12
As a result, the athletes completed a total of 12 laps.

Entre que valores varía la masa corporal MC de la mayoría de estudiantes?
The majority of students have a body mass between 46.7 and 79.1 kg, and there are 36 students with a body mass of 61.7 kg or greater.
Assuming a normal distribution of body mass among the students, we can use the concept of standard deviation to answer the question. Let's assume that the mean body mass of the students is 60 kg, and the standard deviation is 5 kg.
To find the range of body mass where the majority of students fall, we can use the empirical rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Therefore, the range of body mass where the majority of students fall is between 55 kg (60 kg - 5 kg) and 65 kg (60 kg + 5 kg).
To find the number of students with a body mass equal to or greater than 61.7 kg, we need to find the z-score of 61.7 kg, which is
(61.7 - 60) / 5 = 0.34.
We can then use a standard normal distribution table to find the proportion of the area to the right of this z-score, which is 0.3665. This means that approximately 36.65% of the students have a body mass equal to or greater than 61.7 kg.

Historically, your company has calculated bad debts using an aging of accounts receivable. Near the end of the fiscal year, the company is in a cash crunch and needs to borrow money from the bank, using accounts receivable as collateral. The owner of the company knows that many of the accounts receivable are more than 90 days past due, resulting in net receivables equal to only 80% of total receivables. Respond to the following in a minimum of 175 words: The owner asks you to change the method of estimating bad debts to a flat 3% of receivables. What should you do?
If owner asks you to change the method of estimating bad debts to a flat 3% of receivables, then you should carefully "evaluate request to change method of estimating bad-debts", "use prudent and analytical approach" and to communicate effectively with stake-holders.
As a "financial-advisor" for company, it is important to consider request of owner to change method of estimating "bad-debts" to a flat 3% of receivables, given the circumstances described.
(i) It is crucial to understand the reasons behind change in method of estimating bad debts.
In this case, the company is facing a "cash-crunch" and needs to borrow money from the bank, using accounts receivable as collateral.
The owner is aware that many of "accounts-receivable" are more than 90 days past-due, which results in net receivables equal to only 80% of total receivables,
It indicates that company is experiencing a higher level of delinquency in its accounts receivable, and the owner may be seeking a more conservative estimate of bad debts to reflect this situation.
(ii) A more prudent approach would be to conduct a thorough analysis of the company's accounts receivable, considering factors such as the aging of accounts, historical collection patterns, industry norms, economic conditions, and creditworthiness of customers.
This help in developing a more accurate and reliable estimate of bad debts that aligns with the company's specific circumstances.
(iii) it is important to communicate-effectively with owner and other relevant stakeholders, explaining reasons behind recommended method of estimating bad debts and the potential implications of using a flat percentage.
This can help in building transparency, trust, and confidence in the financial reporting process and decision-making of the company.

she spent running on the treadmill inside and on a trail outside each week. These box plots
show the results.
Where was there more variation in the amount of time Celine spent running?
Answer:
There was more variation in her time spent running outside.
Step-by-step explanation:
This is because the range for running outside is larger.
To find range you subtract the largest number in the data by the smallest.
RANGE FOR INSIDE: 150 - 25 = 125
RANGE FOR OUTSIDE: 200 - 50 = 150
Since the range is larger for the time outside spent running, there is more variation.

How to solve for the differenceLet's first find the difference in fractions between the number of girls with brown eyes and the number of girls with blue eyes.
Brown eyes: 7/12
Blue eyes: 1/4
To subtract these fractions, we need to find a common denominator, which in this case is 12. So, we'll convert the fractions to have the same denominator:
7/12 - (3/3)*(1/4) = 7/12 - 3/12
Now, subtract the fractions:
(7 - 3)/12 = 4/12

Which graphical representation would be best to display the data?
Box plot
Histogram
Stem-and-leaf plot
Bar graph
Answer:
Bar Graph
Step-by-step explanation:
A bar graph would be the best graphical representation to display the data.
A bar graph is a good choice for displaying categorical data, where each category is represented by a separate bar. In this case, the categories are the different types of items purchased (Health & Medicine, Beauty, Household, and Grocery), and the number of purchases for each category is represented by the height of the corresponding bar.
A box plot is generally used to display numerical data, while a histogram is used to display the distribution of continuous data. A stem-and-leaf plot can also be used to display numerical data, but it is generally used for smaller datasets.
Therefore, in this case, a bar graph is the most appropriate choice to display the data.
The best graphical representation for the given dataset would be a Bar Graph. The categories of items purchased can be shown on one axis and the number of purchases on the other. Other plots such as Box plots, Histograms, and Stem-and-leaf plots are not suitable for this kind of categorical data.
Explanation:To represent this data graphically, the best option would be a Bar Graph. A bar graph is a graph that uses either horizontal or vertical bars to show comparisons between categories of data. In this case, you have four categories (Item Purchased: Health & Medicine, Beauty, Household, Grocery) and the Number of Purchases associated with each category.
So, each category would be represented by a bar, and the length or height of the bar would represent the Number of Purchases.
Box plots, Histograms, and Stem-and-leaf plots are not appropriate because they are typically used for continuous data or to examine ranges of data, and the data listed here is categorical and discrete (it's countable).

Answer:
To determine which points lie in the solution set of the system of inequalities x-y>-4, 2x-y<5, and 2y + x>1, we can graph the inequalities on a coordinate plane and look for the region that satisfies all three inequalities.
To graph the inequality x-y>-4, we can first graph the line x-y=-4 by plotting the points on the line:
x y
0 -4
-4 0
Then, we can shade the region above the line, since all points above the line will satisfy the inequality x-y>-4:
|
-4 | x
| /
| /
| /
|/
-8 +------
-4 0
To graph the inequality 2x-y<5, we can first graph the line 2x-y=5 by plotting the points on the line:
x y
0 5
2.5 0
Then, we can shade the region below the line, since all points below the line will satisfy the inequality 2x-y<5:
|
5 | x
| / |
| / |
| / |
|/ |
0 +----|--
0 2.5
To graph the inequality 2y + x>1, we can first graph the line 2y + x = 1 by plotting the points on the line:
x y
0 0.5
1 0
Then, we can shade the region above the line, since all points above the line will satisfy the inequality 2y + x>1:
|
2 | x
| |
1|-----
| /
| /
| /
|/
0 +------

The solution set of the system of inequalities is the region that satisfies all three inequalities, which is the shaded region in the graph below:

The area of the composite figure is 343.62 square inches.
What is a 3D composite shape's area?
Composite things that are three dimensional (3D) are created by joining two or more objects. Finding each object's outside surface area and adding the surface areas together will yield the surface area of a 3D composite object.
Area of rectangle = length x width = 12 x 18 = 216 sq in
As a result, the radius is equal to 9 inches, or half the diameter.
[tex]Area \ of\ semicircle = (1/2) * \pi * r^{2} \\\\Area \ of \ semicircle = (1/2) * 3.14 * 9^{2} \\\\Area \ of \ semicircle = 127.62\ sq\ in[/tex]
The combined area of the rectangle and the semicircle is therefore equal to the area of the composite figure as a whole:
Total area = 216 sq in + 127.62 sq in = 343.62 sq in

Part B
In general, how do the measures of the angles in the image compare with the measures of the angles in the preimage?
What affect does the scale factor of the dilation have on the angles, if any?
After a dilation, the angle measures remain constant, meaning that they are not affected by the scale factor of the dilation.
What is a dilation?A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.
The side lengths are changed, but the original figure and the dilated figure are similar, meaning that the angle measures remain constant, no matter the scale factor.
