Answer:
After 1st year, the age distribution will be
\(x_1 = \left[\begin{array}{ccc}1584\\36\\108\end{array}\right]\)
After 2nd year, the age distribution will be
\(x_2 = \left[\begin{array}{ccc}5256\\396\\27\end{array}\right]\)
Step-by-step explanation:
A population has the following characteristics.
A total of 25% of the population survives the first year. Of that 25%, 75% survives the second year.
The average number of offspring for each member of the population is 3 the first year, 5 the second year, and 3 the third year.
From the above information, we can construct a transition age matrix.
\(A = \left[\begin{array}{ccc}3&5&3\\0.25&0&0\\0&0.75&0\end{array}\right]\)
The population now consists of 144 members in each of the three age classes.
From the above information, we can construct the current age matrix.
\(x = \left[\begin{array}{ccc}144\\144\\144\end{array}\right]\)
How many members will there be in each age class in 1 year?
After 1st year, the age distribution will be
\(x_1 = A \cdot x\)
\(x_1 = \left[\begin{array}{ccc}3&5&3\\0.25&0&0\\0&0.75&0\end{array}\right] \times \left[\begin{array}{ccc}144\\144\\144\end{array}\right]\)
The matrix multiplication is possible since the number of columns of first matrix is equal to the number of rows of second matrix.
\(x_1 = \left[\begin{array}{ccc}1584\\36\\108\end{array}\right]\)
After 2nd year, the age distribution will be
\(x_2 = A \cdot x_1\)
\(x_2 = \left[\begin{array}{ccc}3&5&3\\0.25&0&0\\0&0.75&0\end{array}\right] \times \left[\begin{array}{ccc}1584\\36\\108\end{array}\right]\)
\(x_2 = \left[\begin{array}{ccc}5256\\396\\27\end{array}\right]\)

Step-by-step explanation:
it seems you solved the tricky part yourself already.
just to be sure, let's do the first derivative here again.
the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...
f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =
= 3t⁴ + 18t³ + 24t² + 18t + 21
f'(t) = 12t³ + 54t² + 48t + 18
and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).
we simply put the input number (2) at every place of the input variable (t).
so,
f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =
= 426

Given quadrilaterals JKLM and NPQR are similar with K=100°, M=85°, JK=12, LM=(5y+1), MJ=20, RN=10, NP=(x+4), PQ=7, QR=8, you want to identify the true statments.
Relations
Corresponding angles are congruent, so we have ...
∠K≅∠P = 100°
∠M≅∠R = 85°
Corresponding sides have the same ratio. The larger : smaller ratio here appears to be 2 : 1.
JK : NP = 12 : (x+4) ⇒ x+4 = 6 ⇒ x = 2
KL : PQ = ? : 7 ⇒ KL = 14
LM : QR = (5y+1) : 8 ⇒ 5y+1 = 16 ⇒ y = 3
MJ : RN = 20 : 10 . . . . . establishes the ratio for the others
The true statements are ...
x = 2∠R = 85°y = 3__
Additional comment
It can be helpful to write a list of the specific correspondences (based on the similarity or congruence statement).

A 2-column table with 4 rows. Column 1 is labeled x with entries negative 6, negative 4, 4, 6. Column 2 is lab
eled y with entries negative 26, negative 14, 34, 46.
The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).
First, let's find the slope of the line using the formula:
slope (m) = (change in y) / (change in x)
m = (0 - 4) / (5 - 3)
m = -4 / 2
m = -2
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Using the point (3, 4) as our reference point, we have:
y - 4 = -2(x - 3)
Expanding the equation:
y - 4 = -2x + 6
Simplifying:
y = -2x + 10
Now, let's check the given options to find the linear function with the same y-intercept:
Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)
The y-intercept is the same as the given line (10). So, this option is correct.
Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)
The y-intercept is not the same as the given line. So, this option is not correct.
Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

Use the diagram to find the measures of all the angles, given that m<1 = 76º.
Answer:
m<2 = 104º
m<3 = 76º
m<4 = 104º
Step-by-step explanation:
given: m<1 = 76º
m<3 = m<1 this is because they are opposite angles which equals each other
A straight line = 180º
so m<1 + m<2 = 180 and m<3 + m<4 = 180
m<2 = 180 - m<1
m<2 = 180 - 76
m<2 = 104º
m<2 = m<4 so m<4 is also 104º
Hope this helps, Let me know if you have any questions !
m∠1 = 76° Given.
m∠1 ≅ m∠3 Vertical Angle theorem.
m∠3 = 76° CPCTC
m∠1 + m∠2 = 180° (supplementary angles)
m∠3 + m∠2 = 180° (supplementary angles)
m∠1 & m∠3 ∴ Congruent (congruent supplements theorem)
m∠2 + m∠3 = 180° (supplementary angles)
m∠4 + m∠3 = 180° (supplementary angles)
m∠2 & m∠4 ∴ Congruent (congruent supplements theorem)
∴ IF m∠1 = 76° (Given)
THEN:
m∠2 = 104° (Supplementary angles)
m∠3 = 76° (Definition of vertical angles)
m∠4 = 104° (Supplementary angles)
Which equation represents the line that passes through the point (4, -5) and is
perpendicular to the line x + 2y = 5?
А
x - 2y = -14
B
x + 2y = -6
C 2x + y = 3
D
2x - y = 13
Answer:
D. 2x - y = 13
Step-by-step explanation:
We are given the line x + 2y =5
We want to find the equation that is perpendicular to this line, and that also passes through (4, -5)
Perpendicular lines have slopes that multiply to -1
First, let's find the slope of the line
The line is currently in standard form (ax+by=c), which doesn't show the slope; we can convert this line into slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)
To do that, we will need to solve the equation for y
Here it is:
x + 2y = 5
Subtract x from both sides
2y = -x + 5
Divide both sides by 2
y = -1/2x + 5/2
The slope of the line is -1/2
Now, to find the slope of the line perpendicular to it, use this equation:
-1/2m = -1
Multiply both sides by -2
m = 2
The slope of the line perpendicular to it is 2
Here is the equation of the line so far in slope-intercept form
y = 2x + b
We need to find b
As the equation passes through the point (4, -5), we can use it to help solve for b.
Substitute 4 as x and -5 as y.
-5 = 2(4) + b
Multiply
-5 = 8 + b
Subtract 8 from both sides
-13 = b
This is our line:
y = 2x - 13
Even though this is in slope-intercept form, all of the options in your question are in standard form. Ergo, we must convert the line into standard form.
To do this, we can subtract 2x from both sides, as in standard form, x and y are on the same side
-2x + y = -13
Now multiply both sides by -1
2x - y = 13

Answer: 5/8
Step-by-step explanation:
i just added all of them & took out the white and green balls ......... oh and i also simplified itAnswer:
The probability is 5/8
Step-by-step explanation:
First, we must add all the numbers together. 5 + 8 + 7 + 4 = 24. Now, let's add the white balls and green balls. 5 + 4 = 9. Therefore, the probability of choosing a white or green ball is 9/24 which also equals 3/8. To find out the probability of NOT choosing white or green, we must subtract 9 from 24. 24 - 9 = 15. So, the probability of choosing neither the white or green balls equals 15/24 which also equals 5/8.

The following amounts were distributed as dividends: Year 1: $50,000 Year 2: 90,000 Year 3: 130,000 Determine the dividends per share for preferred and common stock for each year. If an answer is zero, enter '0'. Round all answers to two decimal places.
The dividends per share for preferred stock for each year are: Year 1 - $1.25, Year 2 - $2.25, Year 3 - $3.25. The dividends per share for common stock for each year are all $0.
To determine the dividends per share for preferred and common stock for each year, we need to divide the total dividends by the number of shares for each type of stock.
Preferred Stock:
Dividends per share of preferred stock = Total dividends for preferred stock / Number of preferred shares
Year 1:
Dividends per share of preferred stock for Year 1 = $50,000 / 40,000 shares = $1.25
Year 2:
Dividends per share of preferred stock for Year 2 = $90,000 / 40,000 shares = $2.25
Year 3:
Dividends per share of preferred stock for Year 3 = $130,000 / 40,000 shares = $3.25
Common Stock:
Dividends per share of common stock = Total dividends for common stock / Number of common shares
Year 1:
Dividends per share of common stock for Year 1 = ($50,000 - Total dividends for preferred stock) / 100,000 shares = ($50,000 - $50,000) / 100,000 shares = $0
Year 2:
Dividends per share of common stock for Year 2 = ($90,000 - Total dividends for preferred stock) / 100,000 shares = ($90,000 - $90,000) / 100,000 shares = $0
Year 3:
Dividends per share of common stock for Year 3 = ($130,000 - Total dividends for preferred stock) / 100,000 shares = ($130,000 - $130,000) / 100,000 shares = $0
The dividends per share for preferred stock for each year are: Year 1 - $1.25, Year 2 - $2.25, Year 3 - $3.25. The dividends per share for common stock for each year are all $0.

The production line for Colgate toothpaste is designed to fill tubes with a mean of 6 oz. A sample of 30 tubes will be selected to check the filling process. Assume that the sample had a mean of 6.1 oz and a standard deviation of 0.2 oz. We want to perform a hypothesis test at the 0.05 level of significance to help determine if the filling process should continue or if the machine needs to be corrected. We get the following hypotheses:
H 0 μ = 6 H a μ ≠ 6 We got a P-value of 0.0104. Which of the following is a valid conclusion?
A. There is not sufficient sample evidence to support the claim that the true mean weight, in ounces, of all Colgate toothpaste tubes equals 6 oz.
B. There is sufficient sample evidence to support the claim that the true mean weight, in ounces, of all Colgate toothpaste tubes is not 6 oz.
C. There is not sufficient sample evidence to reject the claim that that the true mean weight, in ounces, of all Colgate toothpaste tubes equals 6 oz.
D. There is sufficient sample evidence to support the claim that the true mean weight, in ounces, of all Colgate toothpaste tubes equals 6 oz.
Answer:
B. There is sufficient sample evidence to support the claim that the true mean weight, in ounces, of all Colgate toothpaste tubes is not 6 oz.
Step-by-step explanation:
A two-tailed hypothesis test is performed.
The null and alternative hypothesis are:
\(H_0: \mu=6\\\\H_a:\mu\neq 6\)
The P-value calculated in this test is 0.0104.
As this P-value (0.0104) is smaller than the significance level (0.05), the effect is significant.
The null hypothesis is rejected.
There is enough evidence to support the claim that the mean fill volume differs significantly from 6 oz.

\(P(win) = \frac{Even}{n}\)
So, we have:
\(P(win) = \frac{17}{36}\)
\(P(win) = 0.4722\)

Step-by-step explanation:
Emma has $140 cash to spend at a music store. How much can she spend on items if there is %7 sales tax?
Answer:
$130.84
Step-by-step explanation:
If a 7% sales tax is applied, the cost of the item (including tax) will be 107% of the original price.
To calculate how much Emma can spend if she has $140 cash to spend, divide $140 by 107%:
\(\implies \dfrac{140}{107\%}\)
\(\implies \dfrac{140}{\frac{107}{100}}\)
\(\implies 140 \times \dfrac{100}{107}\)
\(\implies \dfrac{14000}{107}\)
\(\implies 130.84\)
Therefore, Emma can spend $130.84 on items if there is a 7% sales tax.
What is the range of f?
The range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5
Here, we have,
From the question, we are to determine the range of f.
The range of a function is the set of its possible output values.
The graph of the function, f, is shown in the diagram.
From the graph,
The minimum value of f on the x-axis is -6. That is, f(x) ≥ -6
and
The maximum value of f on the x-axis is 5. That is, f(x) ≤ 5
Combining the two expressions, we get
f(x) ≥ -6 and f(x) ≤ 5
That is,
-6 ≤ f(x) and f(x) ≤ 5
∴ -6 ≤ f(x) ≤ 5
Hence, the range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5

Maria saves all her nickels and dimes in a jar on her desk. When she counts her money, she finds that she has 70 coins worth a total of $4.40. How many nickels and how many dimes does she have?
Using a system of equations, it is found that she has 52 nickels and 18 dimes in the desk.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
Variable x: Number of nickels in the desk.Variable y: Number of dimes in the desk.There are 70 coins, hence:
x + y = 70.
A nickel is worth $0.05, while a dime is worth $0.1, and there is a total of $4.40 in the desk, hence:
0.05x + 0.1y = 4.4.
From the first equation, we have that:
y = 70 - x.
Replacing in the second:
0.05x + 0.1(70 - x) = 4.4.
0.05x = 2.6
x = 2.6/0.05.
x = 52
Then:
y = 70 - x = 70 - 52 = 18.
She has 52 nickels and 18 dimes in the desk.

Hey team can spend no more than $300 on shirts the team has already spent $80 how many more shirts for $15 each can I still buy Rite in inequality that represents the situation
He can buy less οr equal tο 14 shirts with the mοney left and The inequality that represents this situatiοn is s (stands fοr shirts) ≤ 14.
What is inequality?In Mathematics, it is the relatiοnship between twο values that are nοt equal. Inequality means twο values that are nοt equal. When the situatiοn is tο cοmpare the values, '≤' οr '≥' sign are used.
Hey team can spend nο mοre than $300 οn shirts the team has already spent $80.
300- 80 = 220
220/ 15 = 14.6
Let us say s be the number οf shirts.
Then the inequality will be s≤14
As the numbers οf shirts cant be a fractiοnal term sο we cοnvert the fractiοnal term tο the integer οne.
Hence, the inequality that represents the situatiοn is s≤14.
