g is greater than -218,020.041.

We have,

To solve this inequality, we need to simplify the left side first:

9999899(-989789) = -9,899,782,581,211

Next, we can solve for g by dividing both sides by 45,426,663:

-9,899,782,581,211 / 45,426,663 < g

Simplifying the left side:

-218,020.041 < g

Therefore,

g is greater than -218,020.041.

Answer:

28.57% chance

Step-by-step explanation:

add them all up which is 14, and if there are 4 white marbles that means its 4/14, which is 28.57 as a percent (2:7 as ratio)

Mean - this is the average. Add up the numbers and divide by the count of the numbers in the data set.

11+13+14+16+17+18+20+20+21+24+25+29 = 228

There are 12 numbers, so divide by 12.

228/12 = 19. The mean is 19.

Median - - - this is the MIDDLE number. Your data is already in numerical order (hooray!) so there are 12 numbers. Since it's even, we'll take the average of the 2 middle numbers. The 6th number is 18 and the 7th number is 20. The average of these is 19. So the median is 19.

(Side note: yes, median and mean can be the same.)

Mode - - - this is repeat/most common numbers! 20 repeats. 20 is the mode.

Range - - - biggest number is 29, littlest is 11. The range is 29-11 = 18.

Part b)

[tex]t_1 = -2\\\\t_2 = -1\\\\k_1 = -9\\\\k_2 = -9\\[/tex]

Step-by-step explanation:

a) Computing MG

We have
[tex]M = \begin{pmatrix}1&4&5\\ \:t_1&3&-1\\ \:1&t_2&1\end{pmatrix}[/tex]

[tex]G = \begin{pmatrix}2&k_1&-19\\ \:1&-4&k_2\\ \:-1&5&11\end{pmatrix}[/tex]

[tex]MG = \begin{pmatrix}1&4&5\\ \:t_1&3&-1\\ \:1&t_2&1\end{pmatrix}\times \begin{pmatrix}2&k_1&-19\\ \:1&-4&k_2\\ \:-1&5&11\end{pmatrix}[/tex]

[tex]= \begin{pmatrix}1&k_1+9&4k_2+36\\ 2t_1+4&t_1k_1-17&-19t_1+3k_2-11\\ t_2+1&k_1-4t_2+5&t_2k_2-8\end{pmatrix}[/tex]

I am using a matrix calculator to compute the product rather than going through the rather cumbersome multiplication exercise by hand

b) One property of matrices is that if M is a matrix and M⁻¹ is its inverse
M x M⁻¹ is the identity matrix which has a 1 along the primary diagonal (top left - bottom right) and zeros everywhere

Here we are given G = M⁻¹ so M x G is an identity matrix

[tex]MG(1, 2) \\= k_1 + 9 = 0\\= > k_1 = -9\\\\MG(1, 3)\; is\\ 4k_2 + 36 = 0\\k_2 = -36/4 = -9\\\\MG(2, 1) = 2t_1 + 4 = 0\\\implies t_1 = -4/2 = -2\\\\MG(3, 1) = t_2 + 1\\t_2 + 1 = 0\\t_2 = -1\\[/tex]

So the values of the variables are

[tex]t_1 = -2\\\\t_2 = -1\\\\k_1 = -9\\\\k_2 = -9\\[/tex]

To check if these are correct, you can plug in these values into the product matrix MG. You will see that all elements except the diagonal elements are 0; diagonal elements are 1

We can expect a student to guess 17 correct answers on a test with 68 four-choice multiple choice questions with probability 0.25.

Since the probability of guessing the correct answer to a four-choice multiple choice question is 0.25, the probability of guessing an incorrect answer is 1 - 0.25 = 0.75.

We can model the number of correct guesses as a binomial distribution with n = 68 (the number of trials) and p = 0.25 (the probability of success, i.e., guessing correctly).

The expected value of a binomial distribution is given by the formula:

E(X) = n * p

So, in this case, the expected number of correct answers that a student should guess on the test is:

E(X) = 68 * 0.25 = 17

Step-by-step explanation:

In the side view diagram, we can see that the tank, the wall, and the floor form a right triangle with the radius of the tank as the hypotenuse. Let x be the distance between the tank and the wall, as shown below:

```

|\

| \

r | \ x

| \

|_ _\

s

```

Using the Pythagorean theorem, we can write:

r^2 = x^2 + s^2

Rearranging this equation, we get:

x^2 = r^2 - s^2

Subtracting r^2 from both sides, we get:

x^2 - r^2 = -s^2

Multiplying both sides by -1, we get:

s^2 - x^2 = 0

Therefore, the equation for the relationship between the two radii is:

s^2 - x^2 = 0

Simplifying this equation, we get:

s^2 = x^2

or

x^2 = s^2

So, there is a zero on one side of the equals sign.

The total number of ways to arrange all 6 tables is 720

There are 15 ways to choose 4 tables out of 6.

(a) There are 6 options for the first table, 5 options left for the second table, 4 options left for the third table, and so on.

Therefore, the total number of ways to arrange all 6 tables is:

6 x 5 x 4 x 3 x 2 x 1 = 720

(b) To choose 4 tables out of 6, we can use the combination formula:

C(6,4) = 6! / (4! x 2!)

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

The angle at A = 90- 35

= 55°

The angle at B = 90-49

= 41°

Angle at the fire = 180-(41+55)

= 180-96 = 84°

Using sine rule

sin84/13 = sin55/x

xsin84 = 13sin55

0.995x = 10.65

x = 10.65/0.995

We can predict that there are approximately 2,250 Art majors in the total population of 7,500 students at ASU based on the sample data.

We have,

We can use the formula for estimating population proportion:

Population proportion = sample proportion x population size

where the sample proportion is the fraction of students in the sample who are Art majors, and the population size is the total number of students in the population.

From the sample of 250 students, 75 said that they are majoring in Art, so the sample proportion of Art majors.

sample proportion = 75/250 = 0.3

The population size is 7,500 students.

Using the formula above, we can estimate the number of Art majors in the total population:

population proportion = sample proportion x population size

population proportion = 0.3 x 7,500

population proportion = 2,250

The surface area of the box increases by 67.26 cm² when the height is increased by 0.7 cm.

Recall the formula, Surface Area (SA) of the rectangular prism is given as:

SA = 2lw + 2lh + 2wh

where

l = length,

w = width,

h =  height

From the diagram, we know that:

l = 18cm

w = 6.3cm

h = 30cm

Substituting these values into the surface area formula, we get:

SA₁ = 2(18)(6.3) + 2(18)(30) + 2(6.3)(30) = 2376 cm²

When the height is increased by 0.7cm, the new height becomes:

h' = h + 0.7cm = 30.7cm

The new surface area can be calculated using the same formula:

SA₂ = 2(18)(6.3) + 2(18)(30.7) + 2(6.3)(30.7) = 2443.26 cm²

The increase in surface area is the difference between the new surface area and the original surface area:

SA₂ - SA₁ = 2443.26 cm² - 2376 cm²

To form and solve an equation for Ashley’s problem, we need to translate the words into mathematical expressions. Here are the steps and solution:

a) Ashley thinks of a number if i double my number and add 6 the answer is 40

Let n be Ashley’s number.

If we double the number, we get 2n.

If we add 6 to the doubled number, we get 2n + 6.

The answer is equal to 40, so we can write an equation: 2n + 6 = 40

To solve for n, we need to isolate it on one side of the equation by using inverse operations.

Using the law of sines, the length of b, to the nearest tenth, is: 21.4.

The Law of Sines is a mathematical equation that relates the lengths of the sides of a triangle to the sines of its angles. It states that for any triangle with sides of length a, b, and c and angles A, B, and C (where C is the largest angle), the following relationship holds:

[tex]\sf \dfrac{a}{sin(A)}= \dfrac{b}{sin(B)} =\dfrac{c}{sin(C)}[/tex]

This equation allows you to solve for the unknown sides or angles of a triangle if you know the lengths of its sides and the measure of at least one of its angles. It is often used in geometry and trigonometry to find the unknown parts of a triangle when you have limited information about it.

Given that triangle ABC has the following measures:

Quantity of butterfat in x gallon + quantity of butterfat in y gallon = total quantity of butterfat,
