Given:
Total people surveyed= 400
people say 'yes'= 300
people say 'no' = 100
Now, proportion in the population who will respond "no" is

Write 247.903 in expanded form
Answer:
The answer is
247.903=200.000+47.000+7.000+0.900+0.003
Step-by-step explanation:
In order to determine the expanded form, we have to know about the rule. The expanded form is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression.
For example:
6.432 in expanded notation form is 6.000 + 0.400 + 0.030 + 0.002
In this case:
247.903=200.000+47.000+7.000+0.900+0.003
What is the transformation of C(9, 3) when dilated by a scale factor of 3, using the origin as the center of dilation?
The transformation of C(9, 3) when dilated by a scale factor of 3, using the origin as the center of dilation is:
C'(27,9)
Step-by-step explanation:Dilation transformation--
A dilation transformation is a transformation which changes the size of the original figure but the shape remain unchanged.
i.e. if any figure is dilated by a scale factor k with the center of dilation as origin.
Then the change pr transformation in each of the vertices of the figure is given by:
(x,y) → (kx,ky)
We are given a point C which is located at C(9,3)
Hence, here k=3
Hence, we get:
C(9,3) → C'(9×3,3×3)
i.e. C(9,3) → C'(27,9)

Find the greatest possible enclosed area of a rectangular corral given 400 feet of fencing
Answer:
Maximum area = 10000 square units.
Step-by-step explanation:
We are given the following information:
Rectangular perimeter of coral = 400 units.
Let length of the coral be x. Then,
Perimeter = 400 = 2(Length +Breadth)
[tex]400 = 2(x + Breadth)\\Breadth = 200 - x[/tex]
Thus, the area of rectangle is given by,
[tex]Area = Length\times Breadth = x\times (200-x) = 200x - x^2[/tex]
Thus, we have to maximize the function:
[tex]f(x) = 200x - x^2[/tex]
We will use double derivative test.
First we differentiate with respect to x.
[tex]\displaystyle\frac{d(f(x))}{dx} = \displaystyle\frac{d(200x - x^2)}{dx} = 200 - 2x[/tex]
Equating this to zero to obtain critical points,
[tex]200 - 2x = 0\\200 = 2x\\x = 100[/tex]
Now, again differentiating with respect to x.
[tex]\displaystyle\frac{d^2(f(x))}{dx^2} = -2 < 0[/tex]
Thus, by double derivative test, local maxima occurs for this function at x = 100
So, Length = x = 100 units
Breadth = 200 - x = 100 units
Maximum area = 10000 square units.

The population for a city is 39194 and grows continuously at the rate of 6.9% each year. What is the approximate population in 17 years?
Answer:
121,854
Step-by-step explanation:
Initial population of the town A= 39194
rate growth of population R= 6.9%= 0.069
we need to find the population after n = 17 years
we can find that easily using growth rate formula
A= P(1+R/100)^n
A= 39194(1+0.069)^17
= 121,854
therefore population at the end of 17 years= 121,854

Jessica is filling glasses with water. Each glass holds 3/5 cup of water. She pours 4 1/5 cups of water into the glasses. How many glasses does she fill with water? Enter your answer in the box.
Answer:
7 glasses
Step-by-step explanation:
Given: Jessica is filling glasses with water. Each glass holds [tex]\frac{3}{5}[/tex] cup of water. She pours [tex]4\frac{1}{5}[/tex] cups of water into the glasses.
To find: The number of glasses she fill with water.
Solution:
Each glass holds [tex]\frac{3}{5}[/tex] cup of water.
She pours [tex]4\frac{1}{5}[/tex] cups of water into the glasses.
To find the number of glasses she fill with water, we need to divide the total volume of water with the volume in each glass.
So, the number of glasses she fill with water can be calculated as
[tex]=\frac{4\frac{1}{5}}{\frac{3}{5}}[/tex]
[tex]= \frac{\frac{21}{5}}{\frac{3}{5} }[/tex]
[tex]=\frac{21}{5}\times\frac{5}{3}[/tex]

[tex]=7[/tex]
So, she can fill 7 such glasses with water.

A cylindrical chemical storage tank mush have a height 4 meters greater than the radius of the top of the tank. determine the radius of the top and the height of the tank if the tank must have a volume of 15.71 cubic meters
Final answer:
To determine the radius and height of the cylindrical tank with a given volume of 15.71 cubic meters, where height is 4 meters greater than the radius, we use the volume formula for a cylinder, resulting in a cubic equation that must be solved.
Explanation:
The question asks for the radius of the top and the height of a cylindrical tank with a volume of 15.71 cubic meters, where the height is 4 meters greater than the radius. The formula for the volume of a cylinder is V = πr²h, where V is volume, r is radius, and h is height. Since h = r + 4, we can write the equation in terms of r as V = πr²(r + 4).
To find the radius, we substitute the given volume, 15.71 m³, into the equation:
15.71 = πr²(r + 4)
This results in a cubic equation which we need to solve to find the value of r. After solving (which may require numerical methods or approximations due to the complexity of cubic equations), we find the value of the radius and can then determine the height by adding 4 meters to the radius.

Answer:
[tex]A=1000(1+\frac{0.023}{12})^{12t}[/tex]
Rate of interest (r) = 0.19% monthly
Step-by-step explanation:
Given: The total amount of money in a saving account after t years.

Jill Hartman earns $750 per week plus 3% of sales in excess of $6,500. If Jill sells $25,000 in the first week, her earnings are:
The earnings of Jill Hartman for the week is A = $1,305
Given data ,
To calculate Jill's earnings for the first week, we need to determine the amount of sales in excess of $6,500 and then calculate her additional earnings based on that amount.
Sales in excess of $6,500 = Total sales - $6,500 = $25,000 - $6,500 = $18,500
Now we can calculate Jill's additional earnings based on the sales in excess of $6,500:
Additional earnings = 3% of sales in excess of $6,500 = 0.03 * $18,500
Additional earnings = $555
Finally, we can calculate Jill's total earnings for the first week by adding her base salary to her additional earnings:
Total earnings = Base salary + Additional earnings = $750 + $555
Total earnings = $1,305
Hence , Jill's earnings for the first week, with sales of $25,000, are $1,305

#SPJ2
Final answer:
To determine the height of a tree that casts a 10 ft shadow, using the ratio from a 6 ft tree that casts a 3.25 ft shadow, we find the tree is approximately 18.46 feet tall through the concept of similar triangles.
Explanation:
The question asks how tall a tree is that casts a 10 ft shadow, given that a 6 ft tree casts a 3.25 ft shadow. This problem can be solved using the concept of similar triangles, where the ratio of the heights of the trees is equal to the ratio of the lengths of their shadows.
To find the height of the tree that casts a 10 ft shadow, we set up the proportion as follows:
Height of first tree / Shadow of first tree = Height of unknown tree / Shadow of unknown tree
Substituting the given values:
6 ft / 3.25 ft = Height of unknown tree / 10 ft
By cross-multiplying and solving for the height of the unknown tree, we get:
(6 ft × 10 ft) / 3.25 ft = 18.46 ft
Therefore, a tree that casts a 10 ft shadow is approximately 18.46 feet tall.
