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.

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.
Hope this helped!
Answer:
520
Step-by-step explanation:
so first you would multiply 6 by 45 which is 270 then add 250 which is 520

A total of 240 people drove to a meeting. Of those peoplewho attended the meeting, 80% drove there. How manypeople attended the meeting?
The total number of people that drove to the meeting is 240
80% drove to the meeting
Let the total number of people who attended the meeting be x
Using the percentage and whole relationship
Part = percentage x whole
whole = x
part = 240
percentage = 80%
240 = 80/100 * x
240 = 0.8x
Divide both sides by 0.8
240/0.8 = 0.8x/0.8
x = 300
The total number of people that attended the meeting is 300

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.
This should help with reading the coordinates at every point.

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:
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 → ±∞
Madison is in the business of manufacturing phones. She must pay a daily fixed cost of $400 to rent the building and equipment, and also pays a cost of $125 per phone produced for materials and labor. Make a table of values and then write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.
The equation that represents the total cost is C = $400 + $125p .
What is the total cost?The equation that represents the total cost is a function of the fixed cost and the variable cost. The fixed cost remains constant regardless of the level of output. The variable cost changes with the level of output.
Total cost = fixed cost + total variable cost
Total cost = fixed cost + (variable cost x total output)
C = $400 + ($125 x p)
C = $400 + $125p
Total cost when 0 phones are made = $400 + $125(0) = $400
Total cost when 1 phone are made = $400 + $125(1) = $525
Total cost when 2 phones are made = $400 + $125(2) = $650
Total cost when 3 phones are made = $400 + $125(3) = $775

Explanation:The given point: (4, -1)
From the point: the coordinate tells us x = 4, y = -1
For a graph of function f, f(x) is the same as y
To represent the point (4, -1) as a funtion of x (that is f(x)), we will replace x in f(x) with the value of the x coordinate. The result when we replace it will the value of the y coordinate
when x = 4
f(4) = the value of the y coordinate

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
