The probability of all 5 marbles being red is (8/26) x (7/25) x (6/24) x (5/23) x (4/22) = 0.000766.
This can also be written as P(RRRRR) = 8/26 x 7/25 x 6/24 x 5/23 x 4/22. This probability is very small, as the chances of randomly selecting only red marbles from the bag is low.
This calculation is based on the formula for combinations, which states that the probability of selecting r items from a group of n items is nCr x Pr, where nCr is the number of combinations of selecting r items from n items and Pr is the probability of selecting a specific item. In this case, n = 26 and r = 5, so the number of combinations of selecting 5 items from 26 items is 26C5. This is equal to 8x7x6x5x4/5x4x3x2x1, or 8x7x6x5x4/120. The probability of selecting a specific item is 1/26, as there are 26 items in the bag. Therefore, P(RRRRR) = 8/26 x 7/25 x 6/24 x 5/23 x 4/22.

An air traffic controller is taking two planes. To start plane a is at an altitude of 2457 feet and plane B is just taking off. Plane eight is gaining altitude at 25.25 ft./s in plane, B is gaining altitude at 70.75 ft./s, how many seconds will pass before the planes are at the same altitude and what will they are out of to be when they’re at that same altitude
Answer: To find the number of seconds it takes for the planes to reach the same altitude, we can use the following formula:
time = (difference in altitude) / (rate of plane B - rate of plane A)
In this case, the difference in altitude is the altitude of plane A (2457 feet) and plane B is just taking off so its altitude is 0 feet.
So, substituting these values into the formula:
time = (2457) / (70.75 - 25.25)
time = 2457 / 45.5
time = 53.7 seconds
So it takes 53.7 seconds for the planes to reach the same altitude. To find out what altitude they will be at when they reach the same altitude, we can use the formula:
Altitude = (rate of plane A x time) + altitude of plane A
Substituting the values we have:
Altitude = (25.25 x 53.7) + 2457
Altitude = 1351.6 + 2457
Altitude = 3809.6 ft
So, both planes will be at 3809.6 ft. when they reach the same altitude.

AB = BA, the first pair of matrices does not satisfy [tex]AB \neq BA[/tex].
Is AB BA correct for all matrices?AB = BA in general, even if A and B are both square. We say that A and B commute if AB = BA. We cannot argue that AB = AC provides B = C for a generic matrix A. (However, since A is invertible, we may multiply both sides of the equation AB = AC to the left by A1 to yield B = C.)
For matrices, A and B, the product AB is not necessarily equal to BA. In fact, matrix multiplication is not commutative in general. Therefore, we need to check each pair of matrices to see if their products are equal in order to determine which pair satisfies [tex]$AB \neq BA$[/tex].
[tex]$$\begin{align*}AB &= \left[\begin{array}{cc}1 & 0 \ 3 & -2\end{array}\right] \left[\begin{array}{cc}7 & 0 \ 3 & 4\end{array}\right] \\\&= \left[\begin{array}{cc}1 \cdot 7 + 0 \cdot 3 & 1 \cdot 0 + 0 \cdot 4 \ 3 \cdot 7 - 2 \cdot 3 & 3 \cdot 0 - 2 \cdot 4\end{array}\right] \\\&= \left[\begin{array}{cc}7 & 0 \ 15 & -8\end{array}\right]\end{align*}[/tex]
[tex]$$\begin{align*}BA &= \left[\begin{array}{cc}7 & 0 \ 3 & 4\end{array}\right] \left[\begin{array}{cc}1 & 0 \ 3 & -2\end{array}\right] \\\&= \left[\begin{array}{cc}7 \cdot 1 + 0 \cdot 3 & 7 \cdot 0 + 0 \cdot (-2) \ 3 \cdot 1 + 4 \cdot 3 & 3 \cdot 0 + 4 \cdot (-2)\end{array}\right] \\\&= \left[\begin{array}{cc}7 & 0 \ 15 & -8\end{array}\right]\end{align*}[/tex]
Since AB = BA, the first pair of matrices does not satisfy [tex]AB \neq BA[/tex]. We can proceed in the same manner to check the other pairs of matrices:
[tex]$$\begin{align*}\\AB &= \left[\begin{array}{cc}1 & 0 \ 3 & -2\end{array}\right] \left[\begin{array}{cc}8 & 0 \ 11 & -3\end{array}\right] \\\&= \left[\begin{array}{cc}1 \cdot 8 + 0 \cdot 11 & 1 \cdot 0 + 0 \cdot (-3) \ 3 \cdot 8 - 2 \cdot 11 & 3 \cdot 0 - 2 \cdot (-3)\end{array}\right] \\\&= \left[\begin{array}{cc}8 & 0 \ 2 & 6\end{array}\right]\end{align*}[/tex]

a certain family has 6 children, consisting of 3 boys and 3 girls. assuming that all birth orders are equally likely, what is the probability that the 3 eldest children are the 3 girls?
The probability that the 3 eldest children are the 3 girls is 0.05.
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
To determine the probability, we can use the permutation.
A permutation is an arrangement of a set of objects in a particular order. It is a way of counting the number of ways that a group of items can be arranged in a specific order.
There are a total of 6! ways in which the 6 children can be ordered. If the first 3 children are girls, there are 3! ways to arrange the 3 girls, and 3! ways to arrange the 3 boys. Therefore, the probability that the 3 eldest children are the 3 girls is
(3! x 3!) / 6! = (6 x 6) / 720 = 0.05

The longer crosspiece needs to be about 18 inches long.
To find the length of the longer crosspiece, you need to use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides equals the square of the longest side (the hypotenuse).
Let's call the length of the longer crosspiece x. Then, we have two right triangles:
x^2 = (37-24)^2 + (13)^2
x^2 = 13^2 + 13^2
Solving for x:
x = sqrt(13^2 + 13^2) = sqrt(2 * 13^2) = 13 * sqrt(2) = 18.03 inches

Nicole is buying dog nuts for the bus ride to cheer competition. Plain glazed donuts are $4 per box and chocolate cake donuts cost $5 per box. She spends a total of $91 for 20 boxes. How many boxes of each kind of donut did she buy?
Answer: We can start solving this problem by using a system of equations. Let x be the number of plain glazed donuts Nicole buys, and y be the number of chocolate cake donuts she buys. We know that:
x + y = 20 (The total number of boxes of donuts she buys is 20)
4x + 5y = 91 (The total amount of money she spends is $91)
We can use the first equation to solve for one variable in terms of the other. For example, we can substitute x = 20 - y into the second equation:
4(20 - y) + 5y = 91
80 - 4y + 5y = 91
-4y + 5y = 91 - 80
y = 11
So Nicole bought 11 boxes of chocolate cake donuts. We can substitute that back into the first equation to find the number of plain glazed donuts she bought:
x + 11 = 20
x = 9
So Nicole bought 9 boxes of plain glazed donuts.
We can check our answer by substituting our values of x and y back into the original equations:
x + y = 9 + 11 = 20 (This is the total number of boxes of donuts she bought, which is 20)
4x + 5y = 4(9) + 5(11) = 91 (This is the total amount of money she spent, which is $91)
Both equations are true, so our solution is correct.

Find the surface area of a square pyramid with side length 2 m and slant height 3 m.
Answer: The surface area of a square pyramid with a side length of 2m and slant height of 3m is 12 square meters.
Step-by-step explanation:
The surface area of a square pyramid can be calculated using the formula:
Surface area = Base area + 4 * (Area of one of the lateral faces)
The base area of the pyramid is the area of the square base, which is the side length squared: 2m * 2m = 4m^2
To find the area of one of the lateral faces, we can use the Pythagorean theorem to find the length of the face, which is the hypotenuse of a right triangle with the slant height and half of the side length as the other two sides.
so, (1/2 * 2m)^2 + 3^2 = x^2
x= (1/2 * 2m)^2 + 3^2
x = 2
Therefore, the surface area of the pyramid is:
Surface area = 4m^2 + 4 * 2m^2 = 4m^2 + 8m^2 = 12m^2
So, the surface area of a square pyramid with a side length of 2m and a slant height of 3m is 12 square meters.
You are buying an old "go to work" pickup with a price tag of $1,600. You apply a down payment of $200. 0. Sales tax is 6. 5%. You will have to borrow $1,504 at 8% interest for one year to complete the purchase. What will your full purchase price be with principal, tax and interest
For the given case the full purchase price will be $1,628.92,Principal will be $1,600, Tax will be $101.60,Interest will be $27.32 and Total is $1,728.92.
To calculate the full purchase price, first, you must calculate the sales tax. To do this, multiply the price of the pickup ($1,600) by the sales tax rate (6.5%), which equals $101.60. Next, you must calculate the interest. To do this, multiply the amount borrowed ($1,504) by the interest rate (8%) and the number of years (1), which equals $27.32.
Finally, you must add the principal ($1,600), the sales tax ($101.60), and the interest ($27.32) to get the full purchase price of $1,728.92. Once you subtract the down payment of $200, the total purchase price is $1,628.92.

Which of the following is the equation of a line parallel to 3y = 6x + 5 that passes through (3, 3)? A. y = 2x - 1 B. y = 2x - 3 C. y + 2x = 1 D. y + 3 = 6x
First, we should find the slope of the line we're starting with.
3y = 6x + 5 can be put into slope-intercept form by dividing both sides by 3.
y = 2x + 5/3
The slope of this line is 2.
A parallel line has to have a slope of 2 as well, so we know we're looking for a line with a slope of 2.
Options A and B have that. Options C and D do not.
Now if (3,3) is a point on the line, then (3,3) must also be a solution for the equation.
Checking Option A:
3 = 2(3) - 1 is not true. 3 ≠ 6 - 1
Checking Option B:
3 = 2(3) - 3 is true. 3 = 6 - 3
Option B is the answer, since it has the right slope and works for the point (3,3).
Answer:
B) y = 2x - 3
Step-by-step explanation:
3y = 6x + 5 To put in the slope intercept form. Divide all the way through by 3
y = 2x + 5/3
When lines are parallel, they have the same slope.
So the slope will be 2. We will use the point to find the y intercept
m = 2
x = 3 This is from the point (3,3)
y = 3 this is from the point (3,3)
y = mx + b
3 = 2(3) + b
3 = 6 + b Subtract 6 from both sides
3-6 = 6- 6 + b
-3 = b
Now that we have the slope (2) and the y intercept (-3) we can write the equation.
y = mx + b
y = 2x -3
The total cost of producing a type of car is given by C(x)=21000−90x+0.1x2, where x is the number of cars produced. How many cars should be produced to incur minimum cost? Please explain how you got the answer, THANKS!
Answer: To find the number of cars that should be produced to incur minimum cost, we need to find the minimum value of the cost function C(x). Since C(x) is a quadratic function, it will have a minimum value, which is either a relative minimum or an absolute minimum. To find the number of cars that should be produced to incur the minimum cost, we will find the derivative of C(x) and set it equal to zero.
To find the derivative of C(x), we can use the power rule, which states that the derivative of x^n is n*x^(n-1).
The derivative of C(x) = 21000 - 90x + 0.1x^2 is
C'(x) = -90 + 0.2x
To find the minimum cost, we set C'(x) equal to zero and solve for x:
-90 + 0.2x = 0
0.2x = 90
x = 450
So, producing 450 cars will incur the minimum cost.
To verify that this is indeed a minimum, we can find the second derivative of C(x) which is 0.2, since the second derivative is positive, we can confirm that x = 450 is a relative minimum.
Alternatively, we can substitute x = 450 into the cost function and find the minimum value, which is C(450) = 21000 - 90(450) + 0.1(450)^2, which is less than any other value of C(x) for x≠450.
Therefore, to incur the minimum cost, 450 cars should be produced.

The function of u that takes the input u and gives output as v is g(u) = - (8v -2)/ 12.
What are functions?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Given that the equation that takes the input and output value to give the function is:
-12u + 3 = 8v + 1
Isolate the value of u.
Subtract 3 from both sides of the equation:
-12u + 3 - 3= 8v + 1 -3
-12u = 8v -2
Divide both sides of the equation with -12.
-12u / -12 = 8v - 2/ -12
u = - (8v -2)/ 12
Hence, the function of u that takes the input u and gives output as v is g(u) = - (8v -2)/ 12.
