What is a geometric sequence?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.
The second parameter is the quantity by which we multiply previous term to get the next term.
We are given that terms shown below are the first three terms of a geometric sequence whose common ratio is positive.
7, 4x+8, 112
Therefore, the common difference is;
r = √(112/7) =√16
r =4
Now, 4x+8 = 28
4x = 28-8
4x = 20
x= 5
The value of X algebraically is 5.

Step-by-step explanation:
Diedra rolls an unbalanced die 72 times and gets a "6" 21 times. If she rolls the die 15 more times, which of these is the most reasonable prediction of the number of times she will not roll a "6"?
By using the relative frequency, we can expect to not roll a "6" in 11 rolls.
How many times can we expect to not roll a "6"?
We know that in a total of 72 rolls, the outcome is "6" 21 times.
Then the relative frequency is:
F = 21/72 = 0.292
Then we can expect that in N rolls, we will get (0.292)*N times a "6".
So the number of times that we will not get a 6, is:
(1 - 0.292)*N
In this case is N = 15, then we get:
(1 - 0.292)*15 = 10.62
Rounding to the next whole number we get 11, this means that we can expect to not roll a "6" in 11 rolls.

Consider the function RX) = 10% and the function g(x), which is shown below. How will the graph of g(x) differ from the graph of AX)?
g() = f(1 - 6) = 1045 – 6)
OA. The graph of g(x) is the graph of AX) shifted 6 units down.
ОВ. The graph of g(x) is the graph of f(x) shifted to the left 6 units.
OC. The graph of g(x) is the graph of AX) shifted 6 units up.
OD. The graph of g(x) is the graph of fx) shifted to the right 6 units.
Answer:
D
Step-by-step explanation:
The right answer is D
I'm sure
The true statement is (d) The graph of g(x) is the graph of f(x) shifted to the right 6 units.
The equation of the function is given as:
[tex]g(x) = f(x -6) = 10^{x-6}[/tex]
The above equation means that, the equation of function f(x) is:
[tex]f(x) = 10^x[/tex]
And the rule of transformation is:
[tex](x,y) \to (x -6,y)[/tex]
This means that:
Function f(x) is shifted right by 6 units to get function g(x)
Hence, the true statement is (d)

What is quadratic function?In maths, a quadratic of degree 2 in one or maybe more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function. Prior to the 20th century, the terms "quadratic polynomial" meaning "quadratic function" were practically interchangeable since it was difficult to distinguish between a polynomial and the related polynomial function.
Authors often mean "having degree approximately 2" and other times "having level at most 2" when they refer to a quadratic polynomial. The functions f and g have different axes of symmetry and different intercepts. This statement is true.

A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane.
When reflecting a figure in a line or in a point, the image is congruent to the preimage.
A reflection maps every point of a figure to an image across a fixed line.

Round 290951.867863 to the nearest hundred.
Answer:
290951. 87
Step-by-step explanation:
you keep what's before the decimal point the same and round what's after it.
The value of each digit in a number is known as the place value. When the number 290951.867863 is Rounded to the nearest hundred the number becomes 291,000.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so on.The hundred mean is multiplied by 100.The hundredth means the hundredth part of that digit which is that digit divided by 100.In any number, the number rounded off to the nearest hundred is when the number is rounded off to its second value before the decimal. Therefore, the given number can be rounded off to the nearest hundred as,
290951.867863 ≈ 291,000
This is because after the hundred place value the digits at the tens and the unit place are 5 and 1, therefore, the number 951, will be rounded off to 1,000.
Hence, when the number 290951.867863 is Rounded to the nearest hundred the number becomes 291,000.

Answer:

Step-by-step explanation:
Given that
The distance between the point is 13 units
x_1 is 5
y_1 is 3
x_2 is -7
We need to find out the y_2
So, the following formula should be used
[tex]d = \sqrt({x_2 - x_1})^2 + (y_2 - y_1)^2\\\\13 = \sqrt({-7-5})^2 + (y_2 - 3)^2\\\\169 = 144 + (y_2)^2 + (-3)^2 - 2(y_2) (-3)\\\\25 = (y_2)^2 + 9 - 6y_2\\\\16 = (y_2)^2 -6y_2\\\\(y_2)^2 -6y_2 - 16 = 0\\\\(y_2)^2 - 8y_2 + 2y_2 - 16 = 0\\\\y_2 (y_2 - 8) + 2(y_2 - 8) = 0\\\\y_2 = 8[/tex]

mean absolute deviation of 90,84,90 93,63???
Answer:
8.4
Step-by-step explanation:
Instructions
This calculator computes the mean absolute deviation from a data set:
You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".
What is the mean absolute deviation
The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.
Mean absolute deviation formula
This calculator uses the following formula for calculating the mean absolute deviation:
$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Step-by-step explanation:
Using proportion
Perimeter of smaller pyramid/ Perimeter of Larger pyramid = volume of smaller pyramid/ volume of Larger pyramid
30/36 = x/64873
Cross Mulitiply
36 × x = 64873 × 30
x = 64873 × 30/36
x = 54060.833333 in³
Approximately = 54061 in³
Therefore, the volume of the smaller pyramid is 54061 in³
