The given series is convergent and the sum S∞ is 5.555
Think about 10 - 8 - 6.4 - 5.12
If the common ratio of the series is between -1 and 1, then a geometric progression will be convergent.
the average ratio,
r = -8/10
⇒ r = -0.8
This equals 1 - 0.8 - 1.
The presented series is hence convergent.
Sum of series = S∞ = a/(1 - r)
Here, first term(a) = 10,
common ratio(r) = -0.8,
S∞ = a/(1 - r)
⇒ S∞ = 10/(1 - (-0.8))
⇒ S∞ = 10/(1 + 0.8)
⇒ S∞ = 10/1.8
⇒ S∞ = 5.555
Therefore, the given series is convergent and the sum S∞ is 5.555

The Tasty Cookies Factory has a new robotic oven that produces 3,258 cookies each day. They sell the cookies in boxes of 12 cookies each. Managers Fatima and Jorge need to figure out how many boxes they can ship out of the factory each day.
The managers want to know how many boxes of 12 cookies can be filled with the 3,258 cookies that have been baked. Fatima starts by subtracting the largest number of boxes she can easily calculate. She knows that 100 boxes of 12 cookies can be put into one crate. How many crates can be filled from the total of 3,258 cookies?
they can ship out 271 boxes each day. 3,258/12 is 271.5 but the 0.5 doesn't matter bc that'd be half a box. a total of 2 crates can be filled fully with another crate that isn't completely full (in total 3 crates max)

The option that best explains the relationship between altitude and the boiling point is; A. There is a strong negative correlation between altitude and water's boiling point.
How to interpret the correlation relationship?In correlation coefficient, we know that a positive correlation occurs when both x and y values increase at the same time while negative correlation occurs when y value decreases as x value increases.
Now, we see from the given graph that y-values are decreasing with increasing x-values and as such this is a negative correlation.
Now, we want to determine whether it is a strong or weak correlation.
The scatterplot is close to being a straight line and as such the correlation coefficient will be close to - 1 which makes it a strong negative correlation.

3. 2) to (77) that nartitions the segment into a ratio of 3 to 2?
Answer:
(4.6, 4)
Step-by-step explanation:
Given the coordinates (3,2) and (7, 7) partitioned between 3:2
M(X,Y) = [(ax1+bx2/a+b, ay1+by2/a+b)]
X = 3(3)+2(7)/3+2
X = 9+14/5
X = 23/5
X = 4.6
Similarly;
Y = 3(2) + 2(7)/3+2
Y = 6+14/5
Y = 20/5
Y = 4
Hence the required coordinate is (4.6, 4)

What is the thickness of each cookie?
The thickness of each cookie is 0.318 cm.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.
We are given that;
Diameter=5cm
Volume= 100cm3
Now,
To find the thickness of each cookie, you need to follow these steps:
Plug in the values into the formula for volume and solve for height:
Volume = π × radius^2 × height
100 = π × 2.5^2 × height
100 = 19.635 × height
height = 100 / 19.635
height = 5.093 cm
Divide the height by the number of cookies to get the thickness of each cookie:
Thickness = height / number of cookies
Thickness = 5.093 / 16
Thickness = 0.318 cm
Therefore, by the volume of cylinder answer will be 0.318 cm.

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 6x + 10
(a)
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 10
y = (x + 3)² + 1 ← in vertex form
(b)
Since a = 1 > 0 then vertex is a minimum
(c)
(h, k ) = (- 3, 1 ) ← coordinates of vertex

What is the coefficient form of X³ 2 *?
Let x= the co-efficient of x^2. So the co-efficient of given function is x=1.
Define co-efficient.
The term "coefficient" refers to a number or symbol that multiplies another number or symbol (used as a mathematical variable).
Write an example of co-efficient.
An amount multiplied by a variable is known as a coefficient. As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.
Let x= the co-efficient of x^2 So the co-efficient of given function is x=1.
The term multiplied with x^3 is the co-efficient of this expression. As there is not term with x^2 so it is 1.

In a survey of 1,500 people who owned a certain type of car, 750 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
If in a survey of 1,500 people who owned a certain type of car, 750 said they would buy that type of car again, the percent of people surveyed who were satisfied with the car is 50%.
To find the percent of people surveyed who were satisfied with the car, we can use the following formula:
percent satisfied = (number of satisfied people / total number of people surveyed) x 100
In this case, the number of satisfied people is 750 and the total number of people surveyed is 1,500. So we have:
percent satisfied = (750 / 1,500) x 100 = 0.5 x 100 = 50%
So, 50% of the people surveyed were satisfied with the car.

Step-by-step explanation:
How do you write numbers more than 100?
The numerical figures are used to write numbers more than 100.
What is numbers?
An arithmetic value known as a number is used to represent a quantity and perform calculations. Numbers are represented by written symbols, such as "3," which are referred to as numerals. A number system is a method of writing that uses logically ordered digits or symbols to represent numbers.
To represent numbers greater than 100, use numeral figures; however, whole numbers, such as 300 or 1,000, should be written out.
When representing non-whole numbers like 1,239 or 603, use numerals.
Except for whole numbers combined with hundred, thousand, hundred thousand, million, billion, and beyond, the Chicago Manual of Style advises spelling out numbers from zero to one hundred and using figures after that (e.g., two hundred; twenty-eight thousand; three hundred thousand; one million).
Hence, the numerical figures are used to write numbers more than 100.

Step-by-step explanation:
We want to simplify:
[tex]\displaystyle \frac{\cos^2(A)}{1+\sin(A)}[/tex]
Recall the Pythagorean Identity:
[tex]\sin^2(A)+\cos^2(A)=1[/tex]
So:
[tex]\cos^2(A)=1-\sin^2(A)[/tex]
Substitute:
[tex]\displaystyle =\frac{1-\sin^2(A)}{1+\sin(A)}[/tex]
Factor. We can use the difference of two squares pattern:
[tex]\displaystyle =\frac{\left(1-\sin(A))(1+\sin(A))}{1+\sin(A)}[/tex]
Cancel. Hence:

a) The flowchart for the congruency of triangles is given below.
b) The triangles are congruent as DQ ≅ XZ, PQ ≅ XY, and ∠PQD ≅ ∠ZXY.
What is congruency?
The word 'congruent' means 'exactly equal' in terms of shape and size. Even when we turn, flip, or rotate the shapes, they remain equal.
In the given diagram, it can be seen that -
Line segment DQ = Line segment XZ.
Similarly, Line segment PQ = Line segment XY.
Since, the two sides of the triangle are equal, hence the third side must also be equal.
Line segment PD = Line segment ZY.
Also, in the diagram it can be seen that ∠PQD ≅ ∠ZXY.
Therefore, the triangles PDQ and ZXY are equal and congruent.

4. — 20.1, 13.4, 9.8, 21.3, 20.8, 19.1, 68.1, 22.6
Mean
The mean of the data is the sum of the data values, divided by the number of data values.
MedianThe median data value is the middle of the sorted list, or the average of the two middle values. Here, there are an even number of data values in each list, so the median is the average of the middle two.
ModeThe mode of the data set is the value that is repeated most often. A data set may have multiple modes. Here, where one of the datasets has no repeated values, we describe it as having "no mode."
Data set 2The first attachment shows the descriptive statistics are ...
mean: 53.75median: 56.5mode: 65The data is skewed to the left, with the value 22 being an outlier. This value reduces the mean. The mode is the maximum value in the data set, so it does not fairly represent the data, either.
The median best represents the data.
Data set 4The second attachment shows the descriptive statistics are ...
mean: 24.4 median: 20.45mode: none (no repeated values)The data is skewed to the right, with the value 68.1 being an outlier. This tends to raise the mean above what it would otherwise be. There is no mode.
