this is very roughly converted from the original question, I bet. no punctuation marks and, and ...

what I understood of the important information is :

there are 23 boxes of books with 12 books in each.

there are 4 teachers dividing the books evenly among themselves for their cells (classes ?) of students.

so, we need to divide the books by 4 to distribute them evenly into 4 parts.

23×12/4 = 23×3 = 69

each teacher got 69 books.

0.721 can be written in scientific notation as 7.21 x \(10^{-1}\)

Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

For example:

1 x 10² is equivalent to 100

1 x \(10^{-1}\) is equivalent to 0.1

To convert 0.721, multiply and raise 10 to the power of -1

by 10  = 7.21 x \(10^{-1}\)

The expected value in a binomial situation with n = 18 and π = 0.60 is E(X) = np = 18 * 0.60 = 10.8.

In a binomial situation, the expected value, denoted as E(X), represents the average or mean outcome of a random variable X. It is calculated by multiplying the number of trials, denoted as n, by the probability of success for each trial, denoted as π.

In this case, we are given n = 18 and π = 0.60. To find the expected value, we multiply the number of trials, 18, by the probability of success, 0.60.

n = 18 (number of trials)

π = 0.60 (probability of success for each trial)

To find the expected value:

E(X) = np

Substitute the given values:

E(X) = 18 * 0.60

Calculate the expected value:

E(X) = 10.8

The area of the first quadrant bounded by the curve and both coordinate axes is 2/3 (\(5^{(3/2)}\) - 5).

The given curve is y² = 5 - x, which is a parabola opening towards the left with a vertex at (5,0).

To find the area of the first quadrant bounded by the curve and both coordinate axes, we need to integrate the curve with respect to x over the range [0,5].

Since the curve is given in terms of y², we can rewrite it as y = ±√(5-x). However, we only need the positive root for the first quadrant, so we have y = √(5-x).

Thus, the area can be calculated as:

A = ∫[0,5] y dx

= ∫[0,5] √(5-x) dx

= 2/3 (\(5^{(3/2)}\) - 5)

The probability of success on the first roll of the die is 5/6. The expected value of the random variable x1, representing the number of rolls needed to get the first success, is 6/5. The probability of success on subsequent rolls, after the first success, is 5/6. The expected values of x2, x3, x4, x5, and x6 are 6/4, 6/3, 6/2, 6/1, and 6/0, respectively. By applying the linearity of expected value, the average number of rolls needed to get each number at least once, E(X), is 6/5 + 6/4 + 6/3 + 6/2 + 6/1 + 6/0.

In this problem, we are interested in finding the expected value of the number of rolls needed to get each number on the die at least once. To begin, on the first roll, there are 5 out of 6 possible outcomes that are considered a success since we have not rolled them before. Therefore, the probability of success on the first roll is 5/6.

Next, we consider the random variable x1, which represents the number of rolls needed to get the first success. Since this follows a geometric distribution with probability of success p = 5/6, the expected value of x1 is given by 1/p, which is 6/5.

After obtaining the first success, the probability of success on subsequent rolls is (6-1)/6 or 5/6, as there are now 5 remaining numbers that have not been rolled. Therefore, the expected values of x2, x3, x4, x5, and x6 are 6/4, 6/3, 6/2, 6/1, and 6/0, respectively, following the same reasoning as for x1.

Finally, by applying the linearity of expected value, the average number of rolls needed to get each number at least once, E(X), is obtained by summing the expected values of x1, x2, x3, x4, x5, and x6. Thus, E(X) = 6/5 + 6/4 + 6/3 + 6/2 + 6/1 + 6/0, which gives the average number of rolls needed to achieve the desired outcome.

Answer:

Think of it like this each circle has 360 degrees so take 360/2 360/3 and so on and see what you get

Step-by-step explanation:

Among the given utility functions, the ones that are linear are u(a) = 2a - 1 and u(b) = a + b. A linear utility function has the form u(x) = ax + b, where a and b are constant.

The utility function u(x) = 1 is linear, as it satisfies the form u(x) = ax + b with a = 0 and b = 1. However, the utility functions u(c) = max{2x - 1, 0} and u(d) = min{x + 2, 3} are not linear.

The utility function u(c) = max{2x - 1, 0} is non-linear because it involves the maximum function. It takes the maximum value between 2x - 1 and 0. Similarly, the utility function u(d) = min{x + 2, 3} is also non-linear because it involves the minimum function. It takes the minimum value between x + 2 and 3. Both of these utility functions involve non-linear operations, making them non-linear utility functions.

The thickness is given as t = 0.227 inches

volume of the dish:

Volume of the dish = length x width x height

= 8.5 x 6.75 x 2.5

= 143.4375 cubic inches

1 cubic inch = 16.3871 cubic centimeters

143.4375 cubic inches = 143.4375 x 16.3871 = 2351.5 cubic centimeters

Mass of the glass = density x volume

= 2.23 x 2351.5

= 5242.845 grams

1 kilogram = 1000 grams

5242.845 grams = 5.242845 kilograms

Total mass of dish and glass = mass of dish + mass of glass

= 0.9 + 5.242845

= 6.142845 kilograms

Volume of glass = (length - 2t) x (width - 2t) x (height - t)

Substituting the given values, we get:

2351.5 = (8.5 - 2t) x (6.75 - 2t) x (2.5 - t)

solve for t using the graphing system

t = 0.227 inches

The number of degrees in ∠ABO is 50°. Therefore, option A is the correct answer.

Given that, in a circle whose centre is O, arc AB contains 100°.

We need to find the number of degrees in ∠ABO.

An arc of a circle is a section of the circumference of the circle between two radii. A central angle of a circle is an angle between two radii with the vertex at the centre. The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.

According to the theorem ∠ABO=1/2 × arc AB.

So, ∠ABO=1/2 × 100°=50°

The number of degrees in ∠ABO is 50°. Therefore, option A is the correct answer.

Answer:

A)

Step-by-step explanation:

A p-value less than 0.05 is considered significant because it indicates strong evidence against the null hypothesis.

A p-value is a measure of the strength of evidence against a null hypothesis. It tells you the probability of getting a test statistic as extreme as the one you observed, assuming the null hypothesis is true.

Now, to answer your question, if a p-value is less than an alpha set at 0.05, it is considered significant. This means that there is less than a 5% chance that the observed effect is due to random chance or error.

In other words, the evidence is strong enough to reject the null hypothesis and support the alternative hypothesis.

To better understand this concept, let's consider an example. Suppose we want to test whether a new drug is effective in treating a certain condition.

The null hypothesis is that the drug has no effect, while the alternative hypothesis is that it does have an effect. We conduct a clinical trial with a sample size of 100 patients and find that 60 of them show improvement after taking the drug.

We calculate a p-value of 0.02, which is less than our alpha of 0.05. This means that there is strong evidence to reject the null hypothesis and conclude that the drug is indeed effective.

Answer:

y = 3x + 21

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  

The equation of the line passes through (-5,6), slope=3 in point-slope form is y = 3x + 21.

The set of points that make up a line in a coordinate system are represented algebraically by a line's equation.

A line's equation has the conventional form ax + by + c = 0.

Here, the variables are x and y, the coefficients are a and b, and the constant term is c.

Equation in point slope form:

The general equation in point slope form is given by

y - y1 = m(x - x1)

where,

(x1,y1) = (-5,6) are the coordinates on  x and y axis.

and, m = 3 is the slope of the line.

Substitute the value in the equation,

y - 6 = 3(x - (-5)

y - 6 = 3(x + 5)

y = x + 21

Therefore, the equation in the point slope form the given coordinates is y = x + 21.
