Jared works as a landscaper. he installs a sprinkler that sprays water in a circle with an 8-foot radius. what is the approximate area covered by the sprinkler?
The approximate area covered by the sprinkler is 200.96 square feet. A ≈ 201 square feet
The approximate area covered by the sprinkler installed by Jared, the landscaper, can be calculated using the formula for the area of a circle, which is A = πr² (where A is the area and r is the radius).
In this case, the radius of the sprinkler is 8 feet, so we can substitute that value into the formula:
A = π(8)²
A ≈ 201 square feet
Therefore, the approximate area covered by the sprinkler is approximately 201 square feet.
Hi! I'd be happy to help you with this question.
To find the approximate area covered by the sprinkler, we need to use the formula for the area of a circle, which is A = π * r^2, where A is the area and r is the radius.
Given that Jared, the landscaper, installs a sprinkler that sprays water in a circle with an 8-foot radius, we can plug in the value of r:
A = π * (8^2)
A = π * 64
Now, using the approximate value of π as 3.14:
A ≈ 3.14 * 64
A ≈ 200.96 square feet
So, the approximate area covered by the sprinkler is 200.96 square feet.

The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time.
The price f(x), in dollars, of fuel A after x months is represented by the function below:
f(x) = 2.27(0.88)x
Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (I'VE ALREADY COMPLETED THIS; fuel A is decreasing by 12% per month. I just need help with Part B.)
Part B: The table below shows the price g(m), in dollars, of fuel B after m months:
m (number of months) 1 2 3 4
g(m) (price in dollars) 3.44 3.30 3.17 3.04
Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.
Answer:
A. .88 < 1, so the price of Fuel A is decreasing by 12% per month.
B. Fuel B, from months 1 to 4:
\( \frac{3.04 - 3.44}{3.44} (100\%) = - 11.63\%\)
Over this four-month period, Fuel B's price has decreased by about 11.63%.
\( \sqrt[3]{1 - .1163} = \sqrt[3]{.8837} = .9596\)
\(1 - .9596 = .0404 = 4.04\%\)
So Fuel B's price has been decreasing by an average of about 4.04% per month. Fuel A recorded the higher percentage change in price per month.
The 2017 balance sheet of Kerber's Tennis Shop, Inc., showed long-term debt of $5 million, and the 2018 balance sheet showed long-term debt of $5.2 million. The 2018 income statement showed an interest expense of $165,000. During 2018, the company had a cash flow to stockholders for the year was $70,000. Suppose you also know that the firm’s net capital spending for 2018 was $1,370,000, and that the firm reduced its net working capital investment by $69,000. What was the firm’s 2018 operating cash flow, or OCF?
Griffin's Goat Farm, Inc., has sales of $686,000, costs of $332,000, depreciation expense of $65,000, interest expense of $48,500, and a tax rate of 24 percent. What is the net income for this firm?
The net income for Griffin's Goat Farm, Inc., was \(\$184,340\).
The operating cash flow (OCF) for Kerber's Tennis Shop, we can use the following formula:
\(OCF = EBIT + Depreciation - Taxes + \triangle Working Capital\)
where EBIT is earnings before interest and taxes.
Calculate EBIT by subtracting interest expense from operating income:
EBIT = Operating Income - Interest Expense
We do not have the information for operating income, but we can use the fact that interest expense was. \(\$165,000\) to calculate EBIT.
EBIT = Interest Expense / (1 - Tax Rate)
= \(\$165,000 / (1 - 0)\)
= \(\$165,000\)
Calculate the change in working capital (Δ Working Capital). We are told that the company reduced its net working capital investment by \(\$69,000\), which means that working capital increased by \(\$69,000\).
Therefore:
\(\triangle Working Capital = \$69,000\)
Now, we can calculate OCF:
OCF = EBIT + Depreciation - Taxes + Δ Working Capital
=\(\$165,000 + 0 - 0 +\ $69,000\)
=\(\$234,000\)
Therefore, the firm’s 2018 operating cash flow (OCF) was \(\$234,000\) .
To calculate the net income for Griffin's Goat Farm, we can use the following formula:
Net Income = EBIT - Interest Expense - Taxes
where EBIT is earnings before interest and taxes. We can calculate EBIT as:
EBIT = Sales - Costs - Depreciation
= \(\$686,000 - \$332,000 - \$65,000\)
=\(\$289,000\)
Next, we need to calculate taxes. We are given a tax rate of 24%, so:
Taxes = Tax Rate x (EBIT - Depreciation)
= \(0.24 \times (\$289,000 - \$65,000)= \$56,160\)
Now, we can calculate net income:
Net Income = EBIT - Interest Expense - Taxes
= \(\$289,000 - \$48,500 - \$56,160= \$184,340\)

e) If x° andare a pair of supplementary angles find them.
f) If pair of complementary angles are in the ratio 4:11, find them.
g) If a pair of supplementary angles are in the ratio 7:5, find them.
Answer:
d) 2p° and (p+15) ° are complementary angles.
2p° + p° + 15° = 90°
3p° = 90° - 15°
p° = 75°/3
p = 25°
Now, 2p° = 2×25° = 50°
(p+15)° = 25°+15° = 40°
e) x° and x°÷4 are supplementary angles.
x° + x°÷4 = 180°
4x + x = 180°×4
5x = 180°×4
x = 180°×4/5
x° = 36° × 4 = 144°
And x°÷4 = 144/4 = 36°
f) Complementary angles in the ratio 4:11
Let the angles be 4x and 11x .
4x + 11x = 90°
15x = 90°
x = 6°
Now, 4x = 4×6 = 24°
11x = 11×6 = 66°
g) Supplementary angles in the ratio 7:5.
Let the angles be 7x and 5x.
7x + 5x = 180°
12x = 180°
x = 180°/12
x = 15°
Hence, 7x = 7×15 = 105°
5x = 5×15 = 75°.

Consider a sample with data values of 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and $2. Compute the mean, median, and mode.
If required, round your answers to two decimal places.
Mean = ________
Median = _________
Mode = _________
The mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)
Given data values are 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and 2. We need to calculate the mean, median, and mode of this sample.So, let's first arrange the data values in ascending order:2, 50, 52, 53, 55, 56, 57, 61, 69, 70, 73
Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:
Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11
Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.
Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).
Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.
Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.
Therefore, the mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

incomes in a certain town are strongly right-skewed with a mean of $36,000 and a standard deviation of $9000. a random sample of 81 households is taken. what is the probability that the sample mean is greater than $37,000?
The sample mean exceeding $37,000 has a 45.5% chance of occurring.
How does one determine probability?The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Odds are not the same as probability. Odds are calculated by dividing the chance of a given event by the probability that it won't.
We can estimate this binomial problem with a normal distribution as the sample size is bigger than 10, which is sufficient.
Determine the z-score first:
z = (x - μ) / σ = (37000 - 36000) / 9000 =0.111
The likelihood P(x > 37000$) = P(x 37000$) 1,
Consequently, in order to find out, we must consult a normal distribution table.
P(z < 0.111) = 0.5441
And
P(x > 37000$) = 1 - 0.5441 = 0.4559
There is therefore a 45.5% chance that the sample $37,000 is the mean.

QUESTION 10 ..... [1.5 marks]
You are testing two random samples of 25 (group 1) people and 27 (group 2) people and you found that
those in the first group are spending in average $38.6 a day and those in the second group re spending in
average $37.4 a day. Assume that the population standard deviation for the first group is $5.3 and the
population standard deviation for the second group is $6.8.
At a = 0.01, can you conclude that there is a significant difference in the average amount on money
each group is spending every day?
Justify your answer by stating what is
(a) the null hypothesis and alternative hypothesis. Explain what test (left-tailed, right-tailed or two-tailed)
you are using. Also find
(b) critical z-value (not the p-value!)
(c) test value
The critical z-value using a z-table or calculator:
Critical z-value = ±2.576.
What is null hypothesis's?
A null hypothesis is a statement or assumption that there is no significant difference or relationship between two or more variables or groups. In statistical hypothesis testing, the null hypothesis is usually denoted as H0 and is tested against an alternative hypothesis (Ha), which is the hypothesis that there is a significant difference or relationship between the variables or groups being studied.
According to the question:
(a) The null hypothesis is that there is no significant difference in the average amount of money spent per day between the two groups. The alternative hypothesis is that there is a significant difference in the average amount of money spent per day between the two groups.
Since we are not given any information about the direction of the difference, we will use a two-tailed test. The appropriate test to use in this situation is the two-sample t-test.
(b) To find the critical z-value, we first need to calculate the degrees of freedom for the test:
df = (n1 + n2 - 2) = (25 + 27 - 2) = 50
Using a significance level of 0.01, we find the critical z-value using a z-table or calculator:
Critical z-value = ±2.576
(c) To find the test value, we will first calculate the pooled standard deviation using the formula:
\(sp = \sqrt{((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2)}\)
where s1 and s2 are the sample standard deviations and n1 and n2 are the sample sizes. Substituting the given values, we get:
\(sp = \sqrt{((24 * 5.3^2) + (26 * 6.8^2)) / 50} = 6.083\)
Next, we calculate the t-value using the formula:
\(t = (x1 - x2) / (sp * \sqrt{1/n1 + 1/n2})\)
where x1 and x2 are the sample means. Substituting the given values, we get:
\(t = (38.6 - 37.4) / (6.083 * \sqrt{1/25 + 1/27}) = 1.213\)
Since the absolute value of the test value is less than the critical z-value, we fail to reject the null hypothesis. Therefore, we cannot conclude that there is a significant difference in the average amount of money spent per day between the two groups.

Step-by-step explanation:
Given:
a₄ = 6a₅ = 10a₆ = 14a₇ = 18a₈ = 22From inspection of the given terms, it is evident that there is a common difference between consecutive terms. Therefore, this is an arithmetic sequence.
A recursive formula for an arithmetic sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.
From inspection of the sequence, we can see that each term is found by adding 4 to the previous term. Therefore, the recursive formula is:
\(\sf a_n=a_{n-1}+4\)
A recursive rule comprises the recursive formula together with the 1st term a₁. To find the 1st term, keep subtracting 4 from each term:
\(\begin{aligned} \sf a_3 & = \sf a_4 - 4\\ & = \sf 6 - 4\\ & = \sf 2\end{aligned}\)
\(\begin{aligned} \sf a_2 & = \sf a_3 - 4\\ & = \sf 2-4 \\ & = \sf -2\end{aligned}\)
\(\begin{aligned} \sf a_1 & = \sf a_2 - 4\\ & = \sf -2-4 \\ & = \sf -6\end{aligned}\)
Therefore, the recursive rule that can be used to find the nth term of the sequence is:

2) and q2 is the same kinda strategy as i explained so, 6.50+4.00= 10.5 and bc there are 3 ppl then times by 3= 31.50 dollars
make sure to add a zero at the end bc we are talking about money
Hope this helps!! x
