Answer:
negative 1/15
Step-by-step explanation:
Points:
(-3,1) (-17,2)
(x1,y1) (x2,y2)
Use the slope formula which is rise over run y2-y1 divided by x2-x1
so
2-1 divided by -17 - (-3)
which is
2-1 divided by -17+3
so

3. What largely determines the climate of a region?
4. Describe the effect of global air circulation on ocean currents and climate.
5. Conduct research on the climate where you live. Prepare a micro-theme with the information that you find
Answers
Answer:
1. The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees to the dark environment of ocean trenches, to lush rain forests and high mountaintops.
2. Climate and nutrition play the biggest part in determining if an organism will live in a biome.
3. Latitude and landscape.
4. The ocean's global circulation system plays a key role in distributing heat energy, regulating weather and climate, and cycling vital nutrients and gases.
5. Humid subtropical. A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications
2. The type of organisms living in a region is largely determined by the climate and the physical environment, such as temperature, precipitation, soil type, and availability of resources.
3. The climate of a region is largely determined by its latitude, elevation, and proximity to large bodies of water. Other factors that contribute to climate include prevailing winds, ocean currents, and the shape and orientation of the land.
4. Global air circulation plays a significant role in ocean currents and climate. Warm air rises at the equator and cools as it moves toward the poles, creating high-pressure zones. Cool air sinks at the poles and moves toward the equator, creating low-pressure zones. This movement of air creates global wind patterns, which in turn drive ocean currents.
5. Micro-theme: I live in San Francisco, California, which has a Mediterranean climate. This means that the summers are dry and warm, while the winters are cool and wet. The city is located on the coast, which moderates its temperature and creates a marine layer that often brings fog in the summer months. The Bay Area is also prone to earthquakes due to its location on the San Andreas Fault.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answers
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centimeters. The blueprint has a scale of three centimeters to four feet. What will be the actual ares of the base of the fountain, in square feet, after it is built? Round your answer to the nearest tenth of a square foot.
Answers
Answer:
452.4 square feet
Finding the diameter:
Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3
18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6
4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet
Finding the area:
Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)
24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)
12 · 12 = 144 now we multiply it by π
π · 144 ≈ 452.38934 lastly we round it
452.4 square feet

If a^x=pi, then what is a^{-x}? Answer in fraction form.
Answers
a^(-x) = 1/(pi^(1/x)) in fractional form.
1/a^x = 1/pi
Next, we can rewrite a^(-x) as 1/a^x and substitute the expression for 1/a^x from the above equation:
a^(-x) = 1/a^x = 1/(pi^(1/x))
The value of \(a^{-x}\) when \(a^x = \pi \ is\ 1/\pi\). To find the value of \(a^{-x}\) when \(a^x = \pi\), we can use the properties of exponents.
First, recall that a^(-x) is the reciprocal of \(a^x\). In other words, \(a^{-x} = 1 / a^x\).
Given that \(a^x = \pi\), we have:
\(a^{-x} = 1 / a^x\\a^{-x} = 1 / \pi\)
So, The value of \(a^{-x}\) when \(a^x = \pi \ is\ 1/\pi\).

What is the probability that the car lot will sell at least 18 cars? __%
What is the probability that a car lot will sell at most 26 cars?__%
Answers
Answer:
first question is 10 other question it doesn't sound right to me
The answers to the blanks are as follows:
1) 18 and 22
2) 14 and 26
3) 84%
4) 99.85%
What is Standard Deviation?'The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.'
According to the given problem,
Number of cars sold each week = 20
Standard deviation = 2
= 20 + (2*2)
= 18
68% : 18 and 22
99.7% : 14 and 26
P( x ≥ 18 ) = 50% + \(\frac{0.68}{2}\)
= 84%
P( x ≤ 26 ) = 1 - \(\frac{(1 - 0.99)}{2}\)
= 99.85%
Hence, we can conclude that 68% will fall between 18 and 22 and 99.7% will fall between 14 and 26. We also concluded that the car lot will sell at least 18 cars is 84% and that they will sell at least 26 cars is 99.85%.

Hope this helps. Have a nice day.
Answer:
C.)Yes because \(3^{2} + 4^{2} = 5^{2}\)
Step-by-step explanation:
The Pythagoras theorem should be applied in this question. This theorem can only be applicable if the triangle has a right angle ( 90° ) therefore it is used.
\(a^{2} + b^{2} = c^{2}\) (The Pythagoras theorem)
\(3^{2} + 4^{2} = 5^{2}\)
\(3^{2}\) = 9 and \(4^{2}\) = 16. So,
9 + 16 = 25 and \(5^{2}\) = 25
∴ The sides proves that it is a right angled triangle.

Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4 In other words, a change of 1 unit in x corresponds to a change of 0.4 units in y. Graph the line and write the equation of the line.
PLS HELP WILL GIVE BRANLIEST + 20 POINTS
Answers
So here the 'unit rate of change' means the slope. It's also referred to as 'rise over run'. A line can be expressed in the form y=mx+b, where m is the slope and b is the y intercept. So here, m is equal to 0.4 and the line is y=0.4x
Think of it this way: if you plug in 1 for x, you get 0.4 for y. So that matches what the problem was saying about a change of 1 unit in x means 0.4 units in y. To graph it, start at 0,0 and move 0.4 up in y direction (rise) and 1 to the right in the x direction (run). If you keep doing that and connect the points, that will be the line
