We have 9 boy kittens and 6 girl kittens, a total of 15 kittens.
9 cats will be selected and we have to calculate the probability that 5 boy kitttens and 4 girl kittens are chosen.
We could have modeled as a binomial experiment, but the probability of choosing a boy kitten is not constant after each selection. Then, we have to select an alternative method.
We can think of it of a combinatorial problem.
In this case, it is a combination problem, as the order of selection does not matter and each kitten is equivalent within its category.
Repetition is not allowed: a kitten selected can not be selected again.
We can start finding all the possible combinations for 9 kittens out of the total 15 kittens:
[tex]C(15,9)=\frac{15!}{9!(15-9)!}=\frac{15!}{9!6!}=5005[/tex]The probability of selecting 5 boys and 4 girls will be the relation between the outcomes where there are 5 boys and 4 girls and the total number of outcomes we have just calculated.
Then, we can now calculate how many combinations of 9 kittens have 5 boys and 4 girls as a product of two combinations: the combinations for the boys C(9;5) and the combinations for the girls C(6;4).
We can calculate this as:
[tex]\begin{gathered} C(9,5)=\frac{9!}{5!4!}=126 \\ C(6,4)=\frac{6!}{4!2!}=15 \\ =>C(9,5)*C(6,4)=126*15=1890 \end{gathered}[/tex]We can now calculate the probability as the ratio of combinations 1890/5005:
[tex]p=\frac{1890}{5005}\approx0.378[/tex]Answer: the probability is 0.378.
Suppose that a certain basketball athlete earned $17,250,000 to play 80 games, each lasting 48 minutes. (Assume no overtime games.)
The amount paid for each is;
1) Amount earned per game = $215625 per game
2) Amount earned per minute played = $4492.1875
3) Amount earned each minute for 2/3 games = $6738.28
4) Amount earned per hour = 4492.1875 * 60 = $269531.25
How to find the rate per game?We are given;
Amount earned by athlete = $17,250,000
Number of games played = 80 Games
Number of minutes per game = 48 minutes
1) Amount earned per game = Amount earned by athlete/Number of games played = 17250000/80 = $215625 per game
2) If he played entire games for the entire minutes;
Amount earned per minute played = 17250000/(80 * 48)
Amount earned per minute played = $4492.1875
3) He played 2/3 of every game. Thus;
Amount earned each minute for 2/3 games = 17250000/((2/3) * 80 * 48)
Amount earned each minute for 2/3 games = $6738.28
4) Since amount earned for every minute is $4492.1875, then we say that;
Amount earned per hour = 4492.1875 * 60 = $269531.25

Easy;
Substitute m (miles) for 45.
250+6(45)
(6 dollars per mile, times 45 miles, plus the 250 flat rate)
250+270
520
So you would be charged 520 dollars total at the end of the evening.

You want to have $15,000 in 11 years. You will invest how much into an account that has an annual rate of 4.4% compounded daily? Round your answer to two decimal places and assume 365 days per year.
Given:
Future Value = $15,000
time (t) = 11 years
rate (r) = 4.4% or 0.044
number of conversions per year (m) = 365
Find: Initial amount or the Principal
Solution:
Formula for Compound Interest is:
[tex]F=P(1+\frac{r}{m})^{mt}[/tex]From that, we can derive the formula for the Principal or the initial amount.
[tex]P=\frac{F}{(1+\frac{r}{m})^{mt}}[/tex]Let's plug in the given data above to the formula of the principal value.
[tex]P=\frac{15,000}{(1+\frac{0.044}{365})^{365\times11}}[/tex]Then, solve for P.
[tex]P=\frac{15,000}{(1.000120548)^{4015}}=\frac{15,000}{1.622504316}\approx9,244.97[/tex]Answer: You must invest $9, 244.97 to the account in order to get $15,000 after 11 years.

What is the slope of y-9=3(x+12)
Step-by-step explanation:
I need help with a table to plot the points
In order to plot a set of coordinates on a graph page, you would need to take account of every pair of x and y values provided. The line that goes horizontally is the x-axis (from left to right). All the negative values move from point zero (the origin).
The ordered pair, or the coordinates tells you where x and y intersect. For example, the first set of coordinates are (2, 9). That means, when x is 2, then y is 9.
Observe that x equals 2 on the right side of the horizontal axis. Next, you look for the spot where y equals 9.
Next step, you carefully trace the spot where x is 2, and trace it up a straight line and at the point where y equals 9 (at the upper part of the y axis), you put a tiny "X" to mark the spot where both values intersect.
Notice that while tracing from x, you move upwards, and while tracing from y, you move towards the right. That point defines the coordinates (2, 9) which is the first line on your table.
You follow a similar step for every one of the other coordinates, which are;
[tex]\begin{gathered} (2,9) \\ (4,3) \\ (6,-6) \\ (0,15) \\ (3,6) \\ (5,0) \\ (\frac{7}{3},8) \end{gathered}[/tex]Please note that I've just attached the same graph, but this time I've labelled the points one by one.

The angles ∠IDA, ∠YDA, and ∠RDI measures 121°, 59°, and 29.5°.
The angle ∠YDF is equal to 121°. The ∠IDA is vertically opposite angle. So, ∠ADI is equal to the ∠YDF. Hence, ∠IDA = 121°.
The angle ∠YDA and the angle ∠ADI form a linear pair. It means ∠YDA and ∠ADI are complimentary angles.
∠YDA + ∠ADI = 180°
∠YDA + 121° = 180°
∠YDA = 180° - 121°
∠YDA = 59°
The ∠FDI is vertically opposite angle to ∠YDA. So, ∠FDI is equal to the ∠YDA. Hence, ∠FDI = 59°. The ray DR bisects the ∠FDI. So, the angle ∠RDI is half of the angle ∠FDI.
∠RDI = (1/2)∠FDI
∠RDI = (1/2)59

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠D + m∠E + m∠F = 180°
(3x + 27) + (4x + 22) + 68 = 180
7x + 49 + 68 = 180
7x = 63
x = 9
So, m∠D = (3(9) + 27)° = 54°.
The exterior angle of D = 180- 54 = 126°.
Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

Answer:
C(x) = 75x + 1908
Step-by-step explanation:
C(x) is the cost function.
The cost of making x bicycles is the sum of the fixed costs and the cost per bicycle.
The fixed cost is $1908.
The cost per bicycle is $75, so the per bicycle cost for x bicycles is 75x.
Add the two costs, and you get:
C(x) = 75x + 1908

Which of the following could be the end behavior of f(x) = -x2 – 4?
Answer:
f(x) = -∞ as x → ±∞
Explanation:
The given function is
f(x) = -x² - 4
To know the end behavior, let's replace x by a greater number and by a smaller number, so
If x = 100
f(x) = -100² - 4
f(x) = -10000 - 4
f(x) = -10004
If x = -100
f(x) = -(-100)² - 4
f(x) = -10000 - 4
f(x) = -10004
So, we can see that no matter if x is negative or positive, the value of f(x) will be positive. Then, we can say that the end behavior is
f(x) = -∞ as x → ±∞
Which equation is perpendicularl to 2x+3y=12A y=2/3X+5B y=-2/3X+5C y=3/2X+5D y= -3/2X+5
The equation of the line perpendicular to the given equation is;
[tex]y\text{ = }\frac{3}{2}x\text{ + 5}[/tex]Option C is the correct answer
Here, we want to select which of the equations in the option is perpendicular to the given equation
Firstly, we need to understand that for two equations to be perpendicular, then the product of their slopes must be equal to -1
Before we proceed to compare, we need to write the equation in the general form
The equation of the line written in the general form will be;
[tex]y\text{ = mx + b}[/tex]where m represents the slope and the term b represents the y-intercept
Now, let us proceed to write the equation in the standard form;
We have this as;
[tex]\begin{gathered} 3y\text{ = -2x + 12} \\ \\ y\text{ = -}\frac{2}{3}x\text{ + 4} \end{gathered}[/tex]Compared with the general form, we can see that the slope of this line is -2/3
Now let us get the slope of the line that would be perpendicular to it;
[tex]\begin{gathered} \frac{-2}{3}\times\text{ m = -1} \\ \\ m\text{ = }\frac{3}{2} \end{gathered}[/tex]Now, the equation perpendicular to what was given will have a slope of 3/2
Fortunately, all the options in the question have been written in the general form
The one with a slope of 3/2 is option C
[tex]y\text{ = }\frac{3}{2}x\text{ + 5}[/tex]
