The ordered pair for the equation 3y - 2x = 12 is:

(0,4).

(0,-4).

(6,2).

None of these choices are correct.

The length of the chord located 0.7 cm from the centre of a circular ring with a 2.5 cm radius is approximately 3.5 cm.

To calculate the length of the chord, we can use the following formula:

Chord Length = 2 x √(r^2 - d^2)

Where r is the radius of the circular ring and d is the distance between the chord and the centre of the circle.

In this case, r = 2.5 cm and d = 0.7 cm. Plugging these values into the formula, we get:

Chord Length = 2 x √(2.5^2 - 0.7^2) ≈ 3.5 cm (rounded to the nearest tenth)

Therefore, the length of the chord is approximately 3.5 cm.

Answer: Width = 5 inches

Concept:

Here, we need to know the idea of the perimeter.

A perimeter is a path that encompasses/surrounds/outlines a shape.

Perimeter of rectangle = 2 (w + l)

w = width

l = length

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

w = w

l = 3w - 2

P = 36 inches

Given formula

P = 2 (w + l)

Substitute the value into the formula

36 = 2 (w + 3w - 2)

Simplify values in the parentheses

36 = 2 (4w -2)

Divide 2 on both sides

36 / 2 = 2 (4w - 2) / 2

18 = 4w - 2

Add 2 on both sides

18 + 2 = 4w - 2 + 2

20 = 4w

Divide 4 on both sides

While linear regression can be a useful tool for prediction, it is important to consider the quality of the data, assess the linearity assumption, and be cautious when extrapolating beyond the observed data range.

This is an example of using linear regression to predict the weight of a kitten at a specific time (10 weeks in this case) based on the given linear model ŷ = 1.7 + 1.48t.

Using linear regression to make predictions is a common practice and can provide reasonable estimates in many cases. However, whether it is considered a best practice for prediction depends on various factors. Here are a few considerations:

Data quality: The accuracy and reliability of the predictions heavily depend on the quality of the data used to build the linear model. If the data used for training the model is representative and accurately reflects the underlying relationship, the predictions are likely to be more reliable.

Linearity assumption: Linear regression assumes a linear relationship between the predictor variable (in this case, time) and the response variable (kitten weight). If the relationship is not truly linear, the predictions may be less accurate. It is important to assess the linearity assumption and consider alternative models if needed.

Extrapolation: When making predictions outside the range of the observed data (such as predicting the weight at 10 weeks when the data only goes up to 8 weeks), caution should be exercised. Extrapolating beyond the observed range can introduce more uncertainty and may lead to less accurate predictions.

In summary, while linear regression can be a useful tool for prediction, it is important to consider the quality of the data, assess the linearity assumption, and be cautious when extrapolating beyond the observed data range.

Answer:

0.02275

Step-by-step explanation:

We use the z score formula to solve for this

z-score is given as: z = (x-μ)/σ

where x is the raw score,

μ is the population mean

σ is the population standard deviation

In the above question:

mean of μ=500

a standard deviation of SD=100

raw score x = 700

Hence, z score = (700 - 500)/ 100

= 200/100

= 2

z score = 2

Using the z score table of normal distribution to find the Probability of z = 2

P( x = z)

= P(x = 700)

= P( z = 2)

= 0.97725

P(x>700) = 1 - P(x = 700)

= 1 - 0.97725

= 0.02275

Therefore, the probability of randomly selecting an individual from this population who has an SAT score greater than 700 is 0.02275

Variable-ratio schedule is a behavior modification tool used in operant conditioning. It is an interval reinforcement technique where a behavior is reinforced after a particular number of times, but this number varies between random trials. It is used to maintain a behavior in the long term.

Out of the options provided, inserting coins into a slot machine is typically reinforced on a variable-ratio schedule.In the case of inserting coins into a slot machine, the player doesn't know how many times they need to play before they receive a payout. As a result, they will keep playing to achieve the reward (variable ratio). This type of reinforcement schedule provides the most prolonged resistance to extinction, meaning the behavior is most likely to be maintained over time.

Finally, checking the mailbox to see if the mail has arrived is an example of a fixed-interval schedule, while paying a cashier for a candy bar is an example of continuous reinforcement. The slot machine reward system is unique in the sense that it keeps the individual guessing, and therefore more motivated to keep on playing. This reinforcement method is highly effective because it rewards behavior after an unpredictable number of responses, making it the most effective in maintaining behavior in the long term.

Sally has been measuring the tree for 4 months

Step-by-step explanation:

The correct question is as follows;

Sally has been measuring the tree in her yard for a science project. The tree has grown 1/2 of an inch each month and grown a total of 2 inches taller. How many months has Sally been measuring this tree?

.........................................................................................

Solution;

The tree has grown 1/2 of an inch each month and has grown a total of 2 inch taller.

We now need to know the number of months in which the measuring has been taking place.

To know the number of months, we simply need to divide the change in height which is 2 inch by the individual month growth rate which is 1/2 inch

So mathematically, that would be 2/1/2 = 2 * 2 = 4 months

The component vector of F parallel to the ramp is approximately 382.2i - 153.2j.



First, we need to find the weight of the boat and trailer that is distributed on each wheel. Since the weight is evenly distributed, we can simply divide the total weight by 2:

440 lb / 2 = 220 lb

Next, we need to find the component vector of the weight parallel to the ramp. To do this, we will use trigonometry and break the weight vector into its x and y components.

Let's start with the y component. The weight vector is acting perpendicular to the ramp, so we need to find the component that is parallel to the ramp. To do this, we can use the sine function:

sin(21°) = y / 220 lb

y = 220 lb * sin(21°) = 75.9 lb

So the y component of the weight vector parallel to the ramp is -75.9 lb (negative because it is acting downwards).

Now, let's find the x component. Again, we need to find the component of the weight vector that is parallel to the ramp, so we can use the cosine function:

cos(21°) = x / 220 lb

x = 220 lb * cos(21°) = 202.9 lb

So the x component of the weight vector parallel to the ramp is 202.9 lb.

Finally, we can put these components together to get the component vector of the weight parallel to the ramp:

Fpar = 202.9i - 75.9j

Rounding to one decimal place, we get:

Fpar = 382.2i - 153.2j

To find h'(3), we need to differentiate the function h(x) = f(x) * g(x) and evaluate it at x = 3. h'(3) = -396

f(x) = 2 - 4x^2, we can differentiate it using the power rule, which states that if f(x) = ax^n, then f'(x) = nax^(n-1).

Applying the power rule, we find that f'(x) = 0 - 8x.

Now, we are also given that g(3) = 8 and g'(3) = 6. Since we know the value of g at x = 3, we can substitute it directly into the expression for h(x) as follows:

h(x) = f(x) * g(x)

h(3) = f(3) * g(3)

Substituting the given values, we have:

h(3) = (2 - 4(3)^2) * 8

Simplifying further:

h(3) = (2 - 36) * 8

h(3) = (-34) * 8

h(3) = -272

Now, to find h'(3), we differentiate h(x) with respect to x. Since h(x) is a product of two functions, we can use the product rule of differentiation.

The product rule states that if h(x) = f(x) * g(x), then h'(x) = f'(x) * g(x) + f(x) * g'(x).

Applying the product rule to our function h(x) = f(x) * g(x), we have:

h'(x) = f'(x) * g(x) + f(x) * g'(x)

Substituting the given values, we have:

h'(x) = (-8x) * g(x) + f(x) * 6

Now, evaluating h'(3), we substitute x = 3:

h'(3) = (-8(3)) * g(3) + f(3) * 6

Using the given values g(3) = 8 and f(3) = 2 - 4(3)^2, we can substitute them into the equation:

h'(3) = (-8(3)) * 8 + (2 - 4(3)^2) * 6

Simplifying further:

h'(3) = (-24) * 8 + (2 - 36) * 6

h'(3) = -192 + (-34) * 6

h'(3) = -192 + (-204)

h'(3) = -396

Therefore, h'(3) = -396.

The amount after discount that Mary would pay if she decides to pay cash is R170n.

What is discount?

A discount is a reduction in the regular selling price of a good or service, either in terms of money or as a percentage.

If the irrigation pipe is marked at R200 per meter, then without the discount, Mary would pay -

R200 per meter x number of meters

Let's say Mary buys n meters of irrigation pipe.

Then the total cost without the discount would be -

R200 per meter x n meters = R200n

With the 15% cash discount, Mary would pay only 85% of this amount, since she gets a 15% reduction.

Therefore, Mary would pay -

85% x R200n = 0.85 x R200 x n

Simplifying this expression, we get -

0.85 x R200 x n = R170n

Therefore, Mary would pay R170 per meter of irrigation pipe after the 15% cash discount.

If she buys n meters of pipe, her total cost would be -

The approximate probability of drawing one orange marble and one green marble from a bag containing five red marbles, four orange marbles, one yellow marble, and three green marbles is approximately 0.154.

To find the approximate probability of drawing marbles, we can use the following formula

probability = (number of favorable outcomes) / (total number of outcomes)

We need to find the number of favorable outcomes where one marble is orange and the other is green. We can choose one orange marble from four orange marbles in the bag in 4 ways, and one green marble from three green marbles in 3 ways. So, the number of favorable outcomes is 4 x 3 = 12.

The total number of ways of choosing two marbles from the bag is 13C2, which is the number of combinations of 2 marbles that can be drawn from the 13 marbles in the bag. Therefore, the total number of outcomes is

13C2 = (13 x 12) / (2 x 1) = 78

Thus, the approximate probability of drawing one orange marble and one green marble is

probability = number of favorable outcomes / total number of outcomes = 12/78 ≈ 0.154

Therefore, the approximate probability of drawing one orange marble and one green marble from the bag is approximately 0.154.

Based on the information that has been gathered about The Howler and The Cylinder of Fate, it seems that the best starting point for the search would be 65 meters due east of the shore. This recommendation is based on several factors, including the location of the sinking and the sea floor and tide patterns in the area.

The angle of depression between the shore and the hypothetical location of The Howler and its treasure should be approximately 30° at this distance. This means that the search boat will be located at the vertex of a 90° angle between the shore and the treasure below. This starting point was chosen because it provides a reasonable distance from shore that is close enough to the sinking location to increase the likelihood of finding the wreckage, but not so close that it would be difficult to navigate or hinder the search efforts.

Furthermore, the angle of depression provides a clear line of sight from the shore to the treasure below, making it easier to locate the wreckage and any potential treasure that may be contained within it. This method of triangulation has been used in numerous search and rescue operations and has proven to be an effective way to locate objects or people that are hidden from view.

In conclusion, starting the search for The Howler and its treasure 65 meters due east of the shore, with an angle of depression of 30°, provides the best chance of success based on the available information about the sinking location and the surrounding area. This method of triangulation is a proven approach that has been used in many other search and rescue missions and is likely to yield positive results in this case as well.
