Step-by-step explanation:

The equation of the best-fit model using the median-fit method is:

y ≈ 5.94x + 70.00

To find the equation of the best-fit model using the median-fit method, we need to calculate the median values of x and y and use them as the summary points.

Given the data points:

(10, 120), (15, 150), and (25, 200)

The median values of x and y are:

Median x = 15

Median y = 150

Now, we can use the median values in the equation of a line (y = mx + c) to find the best-fit model:

Substituting the median values:

150 = m * 15 + c

To solve for m and c, we can use any of the three data points. Let's use (10, 120):

120 = m * 10 + c

We now have a system of equations:

150 = m * 15 + c

120 = m * 10 + c

Solving this system of equations, we find:

m ≈ 5.94

c ≈ 70.00

Among the options provided, the closest match is:

y = 5.94x + 70.00

Answer:

unlikely

Step-by-step explanation:

The proportion of a normal distribution that falls between z = 1.16 and z = +1.16 is 0.3770, which corresponds to option A.

The area under the standard normal curve between two z-scores can be found using the standard normal distribution table.

Since the area under the curve is symmetric around the mean (which is 0 for the standard normal distribution), the area between z = -1.16 and z = 1.16 is the same as the area between z = 0 and z = 1.16, which is half the total area between z = -1.16 and z = 1.16.

Using the standard normal distribution table, we find that the area to the right of z = 1.16 is 0.1230. Therefore, the area between z = 0 and z = 1.16 is:

0.5 - 0.1230 = 0.3770

So the proportion of a normal distribution that falls between z = 1.16 and z = +1.16 is 0.3770, which corresponds to option A.

Answer:

\(y = \frac{1}{8}(x + 4)^2 + 4\)

Step-by-step explanation:

Given:

Focus of parabola: (-4, 6)

Directrix: y = 2

Required:

Equation for the parabola

Using the formula, \( y = \frac{1}{2(b - k)}(x - a)^2 + \frac{1}{2}(b + k) \) , the equation for the parabola can be derived.

Where,

a = -4

b = 6

k = 2

Plug these values into the equation formula

\( y = \frac{1}{2(6 - 2)}(x - (-4))^2 + \frac{1}{2}(6 + 2) \)

\(y = \frac{1}{2(4)}(x + 4)^2 + \frac{1}{2}(8)\)

\(y = \frac{1}{8}(x + 4)^2 + \frac{8}{2}\)

\(y = \frac{1}{8}(x + 4)^2 + 4\)

Answer:

6 cm

Step-by-step explanation:

The area of a triangle can be calculated using the formula:

Area = (1/2) * base * height

We are given that the area of the triangle is 42cm2 and the height is 14cm. Substituting these values into the formula, we get:

42 = (1/2) * base * 14

Multiplying both sides by 2, we get:

84 = base * 14

Dividing both sides by 14, we get:

base = 6

Therefore, the length of the base of the triangle is 6 centimeters.

Answer:

a) x=6

b) x= 498/463

59 estimated by 65 would be 60.

To estimate a number by another number means to find a value that is close to the original number but is easier to work with or understand. Estimation is a method of making quick calculations or approximations, often without the use of a calculator or other precise tool.

To estimate 59 by 65, you can use rounding to the nearest ten. To do this, round both 59 and 65 to the nearest ten, which is 60. Therefore, 59 estimated by 65 is 60.

Im gonna take a guess and say that the number of students is x and the $ collected is y

Step-by-step explanation:

Since the output of the sigmoid function is 0.64, the predicted probability of the observation being malignant is 0.64. We need to set a threshold probability to classify the observation as malignant or benign.

If we set the threshold probability at 0.5, the observation would be classified as malignant, since the predicted probability (0.64) is greater than the threshold probability. However, the choice of threshold probability depends on the specific problem and the costs associated with false positives and false negatives. So, the predicted category would be malignant if the threshold probability is set at 0.5.

(-2) is still -2 so you could put away the parenthesis -(-3) you need to distribute or multiply the - to -3 negative times negative is positive so it will become 3

Now the equation looks like this:

-2+3= 1

Answer:

the answer is 1

Step-by-step explanation:

ok, so you see that there's a negative sign in front of (-3). even if there's no other number in front of the parentheses, there's actually a -1, its just that math omits the 1 to make life easier. With that in mind, whenever you see an even amount of negative signs, the answer's gonna be positive. In this case you just multiple -3 and the negative sign to get +3, and since there's a -2 in front of the -3, you add them together (-2+3) to get 1

The exponential model that calculates the concentration of bacteria after x weeks can be represented by the equation B(x) = 2.1 million * (3^x), the concentration after 1.6 weeks would be approximately 14.87 million bacteria per milliliter.

This equation assumes that the concentration triples each week, starting from the initial concentration of 2.1 million bacteria per milliliter.

To estimate the concentration after 1.6 weeks, we can substitute x = 1.6 into the exponential model. B(1.6) = 2.1 million * (3^1.6) ≈ 14.87 million bacteria per milliliter. Therefore, after 1.6 weeks, the estimated concentration of bacteria in the river would be approximately 14.87 million bacteria per milliliter.

The exponential model B(x) = 2.1 million * (3^x) represents the concentration of bacteria after x weeks, where the concentration triples each week. By substituting x = 1.6 into the equation, we estimate that the concentration after 1.6 weeks would be approximately 14.87 million bacteria per milliliter.
