This cone and sphere have equal volumes.
What is the radius of the sphere?
Answers
Answer:
the radius of the sphere is 12 cm.
Step-by-step explanation:
IN A CONE
vertical height (h) = 27 cm
radius (r) = 32 / 2 = 16 cm
Now the volume of cone is
= 1/3 *h*π*r²
= 1/3 * 27 *π *16²
= 2304π cm³
Also by the question the cone and the sphere have equal volumes so
volume of sphere = volume of cone
= 2304 π cm³
OR, 4/3 πr³ = 2304 π
4/3 * r³ = 2304
r³ = 2304 * 3 / 4
r³ = 1728
r = ∛1728
r = 12 cm

Why is the average approaching 3.5?
Answers
There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
To find the average approaching 3.5, we need to use the concept of the mean or expected value.
The expected value of a random variable is the long-run average value that we would expect to get if we repeat an experiment many times.
In this case, we can consider each roll of a die as an experiment, and the value of the die as the random variable.
Assuming that the die is fair and has six equally likely outcomes, each with a value between 1 and 6, the expected value of the die is:
E(X) = (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5
Therefore, if we roll the die many times, we would expect the long-run average value to be 3.5.
Now, if we have rolled the die 3200 times and the average so far is 3.51, we can calculate the sum of all the values rolled so far as:
Sum = (Average so far) x (Number of rolls) = 3.51 x 3200 = 11232
To find the average approaching 3.5, we need to calculate the average of the remaining rolls. Let's call the number of remaining rolls "n". Then we have:
Average approaching 3.5 = (Sum of remaining rolls) / n
We know that the total number of rolls is 3200, so the number of remaining rolls is:
n = 3200 - (number of rolls already rolled)
n = 3200 - 3200 = 0
Therefore,
There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

Which function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis?
Answers
Answer:
g(x)=-8(3^x)
Step-by-step explanation:
Given: f(x)=3^x
Multiply by 8: f(x)=8(3^x)
Negate function: g(x)=-8(3^x)
The function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).
What is an exponential function?It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x.where a is a constant and a>1
It is given that, the function represents the exponential function f(x) = 3x.
We have to find the function after a vertical stretch by a factor of 8 and a reflection across the x-axis.
We have to do geometric transformation, It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
Thus, the function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).

C

D
label the x-axis "Pieces of Yarn," and label the y-axis "Length (inches)"
Answers
Answer:
I think answers is
D
label the x-axis "Pieces of Yarn," and label the y-axis "Length (inches
The best units to label is C. label the x axis "Length (inches)," and y axis "Pieces of Yarn".
What is Histogram?A histogram is defined as the pictorial representation of data in the form of a bar graph where the X axis represents the columns of classes and Y axis represents the frequency of those classes.
Given that,
Kelvin cut a 4-foot piece of yarn into pieces.
There may be many pieces of yarns.
He measured the length of each piece of yarn to the nearest inch.
Total length of the yarn = 4 foot = 4 × 12 inches = 48 inches
x axis contains the interval range of the length of the pieces in inches.
This length can be divided in to intervals of length 4.
y axis contains the number of pieces of yarn falling in to that interval.
Hence the correct option is C.

Paul Simon delighted a huge gathering in Central Park. The Parks Department set up 610 rows of 610 seats. In addition 20% of the Parks Department's 575 employees were in attendance. The music was so hot that the morning newspaper described the event as a ___________ in Central Park. How many people attended the concert?
Answers
Answer:
372215
Step-by-step explanation:
Total people in concert = Total seats for attendants + additional employees
Seats for public attendants = Rows x seats per rows = 610 x 610 = 372100
Additional employees = 20% of 575 = ( 20/100 ) x 575 = 115
So, total people in concert = 372100 + 115 = 372215
