If 7 is an element in the domain of ​f(x) = 8x-19/2, the corresponding element in the​ range is 46.5

The domain consists of the input function while the range is output function

The corresponding element in the range is calculated by substituting  x = 7 in the given function

​f(x) = 8x - 19/2

when x = 7



​f(x) = 8 * 7 - 19/2

= 56 - 19/2

= 93/2

= 46.5

Answer:

Area = 42.43 square cm

Step-by-step explanation:

Using Heron's Formula :

 \(Area = \sqrt{s\times (s-a) \times (s-b) \times(s -c)} \ , \ where \ s \ =\ \frac{a+ b+ c}{2}\)

Find Area :

\(s = \frac{11 + 9 + 10 }{2} = \frac{30}{2} = 15\)

\(Area = \sqrt{15 \times ( 15 - 11 ) \times { (15 - 9 ) \times ( 15 -10)}\\\\\)

      \(= \sqrt{15 \times 4 \times 6 \times 5}\\\\=\sqrt{1800}\)

Step-by-step explanation:

0.688 will be the probability of getting a nickel from the jar.

Given,

Probability;-

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The number of fortunate situations divided by the total number of coins would be the product between the probability of each occurrence and the likelihood of each event.

Therefore,

P(nickel) = 19/69

P(penny) = 17/68

That is,

P = 19/69 × 17/68

P = 323/4692

P = 0.0688

That is,

The probability of getting nickel from the jar is 0.06888

The statement "3n + 2lg(n + 1) = Θ(2lg(n))" is not true. The correct statement should be "3n + 2lg(n + 1) = O(lg(n))" because the limit-ratio test shows that the ratio between the functions is bounded by a constant.

The statement "2n = Ω(\(n^2\) + 2n)" is also not true. The correct statement should be "2n = O(\(n^2\) + 2n)" because the limit-ratio test shows that the ratio between the functions is bounded by a constant.

The limit-ratio test is a method used to determine the asymptotic behavior of functions. It involves taking the limit of the ratio of two functions as the input size approaches infinity. If the limit is a constant greater than 0, it implies that one function is bounded below or above by a constant multiple of the other function.

In the first statement, when we apply the limit-ratio test to (3n + 2lg(n + 1)) / (2lg(n)), the limit is not a constant but approaches infinity as n grows. Therefore, the correct notation is O(lg(n)).

In the second statement, when we apply the limit-ratio test to 2n / (n^2 + 2n), the limit is not a constant but approaches 0 as n grows. Therefore, the correct notation is O(\(n^2\) + 2n).

It's important to use the correct notations to accurately represent the asymptotic behavior of functions.

Answer:

x = -12

Step-by-step explanation:

x-2(x+1)+3(x+2) = x-4 (equation)

x-2x+2+3x+6 = x-4 (simplify)

2x+8 = x-4 (combine like terms)

x+8 = -4 (subtract x from both sides)

x = -12 (subtract 8 from both sides)

The distance from the point P(-8,-3,5) to the line with the parametric equations x = -8 + 4t, y = -3 + 4t, z = 5 is 0 units.  

To find the distance between a point and a line, we can use the formula:

d = |AP × u| / |u|

where AP is the vector from any point on the line to the given point, u is the direction vector of the line, and × represents the cross product. First, we find the vector AP by subtracting the coordinates of the point P from a point on the line, which is (-8, -3, 5):

AP = (-8, -3, 5) - (-8, -3, 5) = (0, 0, 0)

Next, we find the direction vector u of the line, which is (4, 4, 0). Taking the cross product of AP and u, we get:

AP × u = (0, 0, 0) × (4, 4, 0) = (0, 0, 0)

The magnitude of AP × u is |AP × u| = 0. The magnitude of u is |u| = sqrt(4^2 + 4^2 + 0^2) = sqrt(32) = 4√2. Finally, we can calculate the distance using the formula:

d = |AP × u| / |u| = 0 / (4√2) = 0

A grade of 85.75 or higher is required to be in the top 40% of the class.

Standard deviation is a statistical measure that represents the amount of variability or dispersion in a set of data values. It measures the degree of spread of the data values from the mean (average) of the data set.

To calculate the standard deviation of a data set, you first need to calculate the mean of the data set. Then, for each data point in the set, you calculate the difference between the data point and the mean. These differences are squared and then summed together. Finally, the sum is divided by the total number of data points minus one, and the square root of this value is taken to obtain the standard deviation.

To find the grade required to be in the top 40%, we need to find the z-score corresponding to the 60th percentile (100% - 40% = 60%).

We can use the standard normal distribution, where the mean (μ) is 0 and the standard deviation (σ) is 1, to find the z-score.

The formula for the z-score is:

z = (x - μ) / σ

where x is the value we want to find the z-score for.

To find x, we can rearrange the formula as:

x = μ + z * σ

where μ = 83 and σ = 11 (given in the problem statement).

To find the z-score for the 60th percentile, we can use a standard normal distribution table or a calculator that has a normal distribution function. Using a standard normal distribution table, we find that the z-score corresponding to the 60th percentile is approximately 0.25.

Plugging in the values, we get:

x = 83 + 0.25 * 11

x = 85.75

Therefore, a grade of 85.75 or higher is required to be in the top 40% of the class.

Thus, the probability that two custard-filled donuts are selected in a row) 11/46.

sampling without replacement is the process of selecting a subset of observations at random; once an observation is chosen, it cannot be chosen again. sampling with replacement, whereby one observation may be chosen more than once and a subset of observations is chosen at random.

Given data:

two-dozen (24) donuts

probability = favourable outcome / total outcome

probability (1st custard-filled donut) = total custard-filled donut / total donuts

probability (1st custard-filled donut) = 12/24

probability (1st custard-filled donut) = 1/2

Now,1 is already taken, now total donuts left are 23 with 11 custard-filled donut.

probability (2nd custard-filled donut) = total custard-filled donut / total donuts

probability (2nd custard-filled donut) = 11/23

Now,

probability (two custard-filled donuts in a row) = 1/2 * 11/23

probability (two custard-filled donuts in a row) = 11 / 46

The correct answer is d. det(5a) = 5(det a). If a is an n × n matrix, the determinants det(a) and det(5a) are related by the formula: det(5a) = 5^n(det a).

This is because when you multiply a matrix by a scalar (in this case 5), the determinant gets multiplied by that same scalar raised to the power of the matrix size. In other words, if you have an n x n matrix, and you multiply it by 5, the determinant gets multiplied by 5^n.
However, if the matrix is a 1 x 1 matrix (i.e. just one number), then the determinant is just that number, and so det(5a) = 5(det a) still holds.
So the only option that is true is d. det(5a) = 5(det a). Your answer: If a is an n × n matrix, the determinants det(a) and det(5a) are related by the formula: det(5a) = 5^n(det a). So, the correct option is c. det(5a) = 5^n(det a).
