Given the geometric sequence an with the following information, find a10.
a2=-36 a7=128/27
The 10th term of the sequence is 1024/729
Finding the 10th term of the sequenceFrom the question, we have the following parameters that can be used in our computation:
a2 = 36
a7 = 128/27
The nth term of a geometric sequence is
an = a1 * r^(n -1)
So, we have
a2 = a1 * r = 36
a7 = a1 * r^6 = 128/27
Divide the equations
r^5 = (128)/(27 * 36)
This gives
r = [(128)/(972)]^1/5
So, we have
r = [(32)/(243)]^1/5
r = 2/5
Also, we have
a1 = 128/(27r^6)
The 10th term of the sequence is
a10 = a1 * r^9
So, we have
a10 = 128/(27r^6) * r^9
This gives
a10 = 128/(27) * r^3
This gives
a10 = 128/(27) * [2/3]^3
Evaluate
a10 = 128/27 * 8/27
This gives
a10 = 1024/729
Hence, the 10th term is 1024/729

The inverse of the given function include the following: A. G⁻¹(x) = (x + 2)/5
What is an inverse function?In Mathematics and Geometry, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).
In this exercise, you are required to determine the inverse of the function f(x). This ultimately implies that, we would have to swap (interchange) both the independent value (x-value) and dependent value (y-value) as follows;
g(x) = y = 5x - 2
x = 5y - 2
5y = x + 2
By dividing all through by 5, we have;
G⁻¹(x) = y⁻¹ = (x + 2)/5

Solve the following simultaneous equation using algebra
6x+3y=45
The solution to the simultaneous equation is x = 6 and y = 3.
To solve this system of equations, we can use the method of elimination. First, we want to eliminate one of the variables, either x or y. In this case, it is easiest to eliminate y. To do so, we can multiply the second equation by 3, which gives us:
6x + 3y = 45
6x - 6y = 18
Now, we can subtract the second equation from the first:
6x + 3y - (6x - 6y) = 45 - 18
Simplifying this expression, we get:
9y = 27
Dividing both sides by 9, we get:
y = 3
Now that we know the value of y, we can substitute it into either equation to find the value of x. Let's use the first equation:
6x + 3y = 45
6x + 3(3) = 45
6x + 9 = 45
Subtracting 9 from both sides, we get:
6x = 36
Dividing both sides by 6, we get:
x = 6

The random probability of event X, wheel stopping on a white slice is 0.9 while the probability of not X, wheel stopping on Grey slice is 0.1
What is the explanation for this?Total numbers on wheel = total possible outcomes
= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Grey colored portion = {3}
White colored portion = {1, 2, 4, 5, 6, 7, 8, 9, 10}
X = Event that wheel stops on a white slice
P(X) = number of white slices ÷ total number of slices
P(X) = 9 / 10 = 0.9
P(not X) = 1 - P(X)
P(not X) = 1 - 0.9 = 0.1
Therefore, the probability that wheel stops on a white slice is 0.9 while, the probability that wheel does not stop on a white slice is 0.1

A high school baseball player has a 0.197 batting average. In one game, he gets 8 at bats. What is the probability he will get at least 2 hits in the game?
The probability of the high school baseball player getting at least 2 hits in a game with 8 at bats, given his 0.197 batting average, is approximately 0.378.
To calculate the probability of the player getting exactly 2 hits in the game, we can use the binomial probability formula:
P(X = x) = (n choose x) x pˣ x (1-p)ⁿ⁻ˣ
Where:
P(X = x) is the probability of getting exactly k hits
n is the number of trials (in this case, 8 at bats)
k is the number of successful trials (in this case, 2 hits)
p is the probability of a successful trial (in this case, 0.197)
Using this formula, we can calculate the probability of the player getting exactly 2 hits in the game:
P(X = 2) = (8 choose 2) x 0.197² x (1-0.197)⁸⁻² = 0.214
So the probability of the player getting exactly 2 hits in the game is 0.214.
To calculate the probability of the player getting at least 2 hits in the game, we need to add up the probabilities of getting exactly 2 hits, exactly 3 hits, exactly 4 hits, and so on, up to 8 hits. This can be a bit cumbersome to do by hand, but fortunately, there are tools available to help us with this.
Using a binomial probability calculator or a statistical software program, we can find that the probability of the player getting at least 2 hits in the game is approximately 0.378.

Determine the amount of gravy needed to cover the turkey:
We know that Bernice made 950 ml of gravy to go with a 5 kg turkey.
There are different ways to estimate how much gravy is needed to cover a turkey, but a common rule of thumb is to allow for about 1/2 cup (or 120 ml) of gravy per serving.
Assuming that the turkey will be served to about 8 people, we can estimate that Bernice will need:
We can write it as an expression:
= 120 ml/serving x 8 servings
= 960 ml of gravy
This means that Bernice made just enough gravy to cover the turkey and have a little bit left over.
Calculate how much gravy will be left in the pot:
We know that the capacity of the gravy dish is 540 ml.
If Bernice fills up the gravy dish with gravy, she will have.

The area of the enclosed region is 16√2 - 8 squared units
We have,
The region enclosed between the curves y = 4 sin(x) and y = 4 cos(x) from x = 0 to x = 0.9π consists of two parts, one above the x-axis and one below the x-axis. We can find the area of each part separately and then add them to get the total area.
First, let's find the x-coordinates of the points where the curves intersect. These are the points where 4 sin(x) = 4 cos(x), or sin(x) = cos(x), which occurs when x = π/4 + kπ/2 for any integer k. Since we are only interested in the intersection points between x = 0 and x = 0.9π, we only need to consider the case k = 0. So the intersection point is x = π/4.
Now, let's consider the part of the region above the x-axis. We need to find the area between the curves y = 4 sin(x) and y = 4 cos(x) from x = 0 to x = π/4. This is given by the integral:
A1 = ∫[0, π/4] (4 sin(x) - 4 cos(x)) dx
Using the identities sin(x) = cos(x - π/2) and cos(x) = sin(x + π/2), we can rewrite this as:
A1 = ∫[0, π/4] (4 sin(x) - 4 sin(x + π/2)) dx
= ∫[0, π/4] (4 sin(x) + 4 sin(x)) dx (since sin(x + π/2) = sin(x))
= 8 ∫[0, π/4] sin(x) dx
= 8 [-cos(x)] [0, π/4]
= 8 (1 - 1/√2)
= 8√2 - 8
Next, let's consider the part of the region below the x-axis. We need to find the area between the curves y = 4 cos(x) and y = 4 sin(x) from x = π/4 to x = 0.9π. This is given by the integral:
A2 = ∫[π/4, 0.9π] (4 cos(x) - 4 sin(x)) dx
Using the identities sin(x) = cos(x - π/2) and cos(x) = sin(x + π/2), we can rewrite this as:
A2 = ∫[π/4, 0.9π] (4 cos(x) - 4 cos(x - π/2)) dx
= ∫[π/4, 0.9π] (4 cos(x) + 4 sin(x)) dx (since cos(x - π/2) = sin(x))
= 4 ∫[π/4, 0.9π] (2 cos(x) + 2 sin(x)) dx
= 4 [2 sin(x) - 2 cos(x)] [π/4, 0.9π]
= 4 (2/√2 + 2) - 4 (1 - 1/√2)
= 8√2
So the total area of the region enclosed between the curves y = 4 sin(x) and y = 4 cos(x) from x = 0 to x = 0.9π is:
A = A1 + A2
A = 8√2 - 8 + 8√2
A = 16√2 - 8 squared units

Shandin looks at the prices of 5 skateboards. The prices are $65, $79, $95, $80, and $175. These prices contain one extreme value ($175). Which measure of center should Shandin use to describe the prices? A. Mean absolute deviation (MAD) OB. Mean O C. Range O D. Median
Answer:
Shandin should use the median to describe the prices since it is a more robust measure of center that is not affected by extreme values. In this case, the median is $80, which represents the middle value when the prices are arranged in ascending order: $65, $79, $80, $95, and $175. The mean and range can be affected by the extreme value of $175, and the MAD is a measure of dispersion rather than center.

The probability of winning on the first roll is 0.22
Solution-
As in the game of casino, two dice are rolled simultaneously.
So the sample space would be,
|S| = 36
Let E be the event such that the sum of two numbers are 7, so
E = {(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)}
|E| = 6
P(E) = 6/36
Let F be the event such that the sum of two numbers are 11, so
F = {(6,5), (5,6)}
|F| = 2
P(F) = 2/36
Now,
P(E∪F)= 0.22

where:
I is the monthly interest
P is the loan amount minus the down payment (i.e., $245,000 - $44,000 = $201,000 in this case)
r is the annual interest rate (i.e., 3.5%)
n is the number of payments per year (i.e., 12 for monthly payments)

What is the volume of the prism?
195 yd3
ninety seven and one half yd3
forty eight and three fourths yd3
thirty five and one half yd3
The volume of the rectangular prism is 97.5 cubic yards. (option b).
In this case, the rectangular prism has dimensions of 3 yards by 5 yards by 6 and one-half yard. To find its volume, we need to multiply these three dimensions together.
First, we need to convert the height of the prism to yards, as the other two dimensions are already given in yards. We know that 1 yard is equal to 3 feet, so 6 and one-half yards is equal to (6 x 3) + (1/2 x 3) = 18 + 1.5 = 19.5 feet. We then convert this to yards by dividing by 3, which gives us 6.5 yards.
Now, we can find the volume of the rectangular prism by multiplying the three dimensions together:
Volume = length x width x height
Volume = 3 yards x 5 yards x 6.5 yards
Volume = 97.5 cubic yards
Hence the correct option is (b).
