From the information given:
To create the required stochastic matrix, we need to take parents who are shown to be vegetarian or nonvegetarian in the column and the children who are vegetarian or nonvegetarian into the row section.
So;
Vegetarian V → 70% → nonvegetarian NV → 30%
nonvegetarian NV → 40% vegetarian V → 60%
V NV
The 2x2 stochastic matrix = [tex]\left \Big { {{V} \atop {NV}} \right.} \left [\begin{array} {cc}0.7&0.4\\0.3&0.6\\\end{array}\right][/tex]

Gustav is starting a special sprinting regimen in outdoor track. The regimen suggests sprinting for a certain number of seconds, sss, at first. The second time he sprints, he should run 150 more seconds than the first time. For the third time, the regimen suggests sprinting twice the number of seconds as the first time. Finally, the regimen suggests an 80-second sprint. Which of the following functions can be used to find the total number of seconds, t, suggested by the entire sprinting regimen?
a. t=s+230
b. t=2s+230
c. t=5/2s+230
d. t=4s+230
Answer: d. t = 4s + 230
Step-by-step explanation: In the first part of his regimen, Gustav sprints for a time of s seconds:
part 1: t₁ = s
In the second part, time is 150 more seconds than first part:
part 2: t₂ = s + 150
In part 3, time is twice the number as the first time:
part 3: t₃ = 2s
And in the last part, the regimen is of an 80 second sprint:
part 4: t₄ = 80
Th entire regimen has a total of seconds equal to
[tex]t=t_{1}+t_{2}+t_{3}+t_{4}[/tex]
t = s + s + 150 + 2s = 80
t = 4s + 230
The function which represents the total number of seconds suggest by the entire regimen is t = 4s + 230

HELP ME PLEASE !! Last year, Eric biked n miles. This year, he biked 457 miles. Using n , write an expression for the total number of miles he biked.
====================================================
Explanation:
The variable n is a placeholder for a number. Specifically some positive number. Let's say that n = 50. This means Eric biked 50 miles last year.
That would mean in total he biked 50+457 = 507 miles overall over the two years.
Since we don't know what n is, we don't replace it with 50. So we just keep n as it is. We would keep it as n+457
Once, or if, we find out the value of n, then we can replace that letter with that number.

3. For the polynomial g(x) = x^4 - 8x^3 + 23^2 - 26x + 10, you are told that the zeros include x=1, x = -3 + i, and x = 3+i.
Explain how you know this list is incorrect. Then you are told that two of the given zeros are correct, with one of them having a multiplicity of 2. Use this information to determine all zeros of g(x). Be sure to show and explain all steps.
Step-by-step explanation:
If the polynomial has complex roots, the conjugates of those complex roots must also be part of the zeroes.
Therefore x = -3 - i and x = 3 - i are also zeroes of g(x). However this means that g(x) has 5 solutions when the degree of g(x) is 4. This is impossible, and hence the list is incorrect.
If either of the complex roots (x = -3 + i or x = 3 + i) had a multiplicity of 2, their conjugates will also have a multiplicity of 2, which is impossible as discussed previously.
Therefore x = 1 has a multiplicity of 2.
We have
x⁴ - 8x³ + 23x² - 26x + 10 = (x - 1)²(Ax² + Bx + C).
= (x² - 2x + 1)(Ax² + Bx + C)
= Ax⁴ + (B - 2A)x³ + (A + C - 2B)x² + (B - 2C)x + C
By Comparing Coefficients,
A = 1,
B - 2A = -8,
A + C - 2B = 23,
B - 2C = -26,
C = 10
Solving them we get A = 1, B = -6 and C = 10.
Hence x⁴ - 8x³ + 23x² - 26x + 10
= (x - 1)²(x² - 6x + 10).
Using the Quadratic Formula on x² - 6x + 10,
we find that the correct complex roots are
x = 3 + i and x = 3 - i.
Hence,
the zeroes of g(x) are x = 1, x = 3 + i and x = 3 - i.
What is the area of this figure? Enter your answer in the box.
Answer:
81 square meters
Step-by-step explanation:
So you can split this figure into one parallelogram (on the bottom) and one triangle (on the top). Find the area of each and then add them together.
The area of a parallelogram is always just length * width, so in this case that would be 9 * 5 = 45 square meters.
Next, the area of a triangle is base * height / 2, so before you can solve you have to find the length of the base.
Going back to the parallelogram, the sides opposite each other are always equal, meaning that if the bottom has a length of 9, the top also has a length of 9.
This means that the top of the parallelogram, which is also the base of the triangle, has a length of 9 m. Now, plug those numbers into the formula for area of a triangle, so:
9 * 8 / 2 = 72 / 2 = 36 square m.
The last step is to add the two areas together:
45 + 36 = 81 square meters.

Given that CD is the perpendicular bisector of AB, which of the following statements can be used to show that AC=BC?
Answer:
B. ΔAXC ≅ ΔBXC by SSS, so AC ≅ BC because they are corresponding parts of congruent triangles.
Step-by-step explanation:
From the given diagram, XC is common to ΔAXC and ΔBXC.
And it can be observed that CD divides AB into two equal length segments.
Thus,
AX ≅ BX (bisection property of a line)
AC ≅ BC (congruence property of triangles)
Therefore, the congruence relationship between triangles ΔAXC and ΔBXC would be, Side-Side-Side (SSS) so as to show that AC ≅ BC.
solve equation:
2x-26=0
Answer:
x = 13
Step-by-step explanation:
You want to solve for x, so move anything not including x to the other side of the equal sign. In this problem, you want to add 26 to zero to move it.
Now your equation will look like 2x = 26
Divide both sides by 2 to solve for x
x = 13

What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Present Weight = 55 Kg, which is 10% higher than her normal weight.
let her normal weight be x.
So, x+ 10% of x = 55
x+ 1/10 x = 55
11x /10 = 55
11x= 550
x= 50
Hence, Ceri normal weight is 50 Kg.
