Find the area of the regular polygon. Round to the nearest tenth.
Given:
The figure of a regular polygon.
To find:
The area of the regular polygon.
Solution:
From the given figure it is clear that the regular polygon has 4 vertices. It means, it is a square.
Distance between the center and the vertex is 7 yd. So, the diagonal of the square is
[tex]d=7+7[/tex]
[tex]d=14[/tex] yd
We know that, area of a square is
[tex]A=\dfrac{1}{2}d^2[/tex]
Putting d=14 in the above formula, we get
[tex]A=\dfrac{1}{2}(14)^2[/tex]
[tex]A=\dfrac{1}{2}(196)[/tex]
[tex]A=98[/tex]
Therefore, the area of the regular polygon is 98 sq. yd.

Solution:
Two number are 19.8 and 5.
On rounding the given numbers to the nearest whole number, we get 20 and 5.
Now, the estimated product is
[tex]20\times 5=100[/tex]
Therefore, the estimated product of given numbers is 100.

You deposit $200 in an account that earns 4% simple interest. How much interest did you earn in 3 years? (Hint: I = prt)
Answer:
$24.
Step-by-step explanation:
Given that I deposited $ 200 in an account that earns 4% simple interest annually, to determine how much interest did I earn in 3 years, the following calculation must be performed:
((200 x 4/100) x 3) = X
((800/100) x 3) = X
(8 x 3) = X
24 = X
Thus, after 3 years of investment I will have earned $ 24 in interest.

One side, in inches, of a triangle is 5 more than twice a number. If this is an equilateral
triangle, what is the perimeter ?
Definition of an equilateral triangle: A triangle with the exact same sides and angles, which is 60°
5 more than twice a number:
Let the number be x:
2x + 5
Since it is an equilateral triangle, multiply that by 3:
3(2x +5) = 6x + 15
The perimeter is (6x + 15) inches.

what is the difference between a quadratic function and a quadratic equation
Answer:
The roots of a quadratic equation simply tell what values of x will make the equation true. A quadratic function is a function where the largest power for the variable is 2. ... A quadratic equation is given to you so that you can solve it for the variable. A quadratic function is given to you so that you can graph it.

Before you read this!! To me, it looks like 8 is the entire length of lineJL, but it may only be the length of lineJM. I've written the steps for lineJL=8 NOT lineJM=8. If this is not the case and 8 is only the length of lineJM let me know so I can fix my answer!
Step-by-step explanation:
The area of a triangle is A=1/2(b)(h)
B=base
H=height
Your height is found in the line in the middle of the triangle, for you it is 6.
The base is the long bottom line on the triangle (lineJL), for you it is 8.
So let's put it in.
A=1/2(8)(6)
A=24sq units (C)

A line passes through the point (4, -3) and has a slope of
4
Write an equation in slope-intercept form for this line.
Answer:
y = 4x -19
Step-by-step explanation:
y = 4x + b
first we add the point to the equation and then we solve for b
-3 = 4 ( 4 ) + b
-3 = 16 + b
-16
-19 = b

A certain financial services company uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time. Suppose that in February 2012, a sample of 1,000 adults showed 410 indicating that their financial security was more than fair. In February 2010, a sample of 1,100 adults showed 385 indicating that their financial security was more than fair.
Required:
a. State the hypothesis that can be used to test for a significant difference between the population proportions for the two years?
b. What is the sample proportion indicating that their financial security was more that fair in 2012?In 2010?
c. Conduct the hypothesis test and compute the p-value.At a .05 level of significance what is your conclusion?
d. What is the 95% confidence interval estimate of the difference between the two population proportion?
Answer:
The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.
Step-by-step explanation:
Let p1 be the sample of 1000 adults chosen in 2012 and
p2 be the sample of 1100 adults chosen in 2010
Part a:
The hypothesis that can be used to test for a significant difference between the population proportions for the two years is:
H0: p1-p2= 0 against the claim Ha: p1-p2≠0
Part b:
The sample proportion indicating that their financial security was more that fair in 2012 is
p1^= 410/1000= 0.41
In 2010 is:
p2^= 385/1100= 0.35
Part c:
p^c= 410+385/1000+1100= 0.3785
q^c= 1-p^c= 1-0.3785= 0.6124
The critical region is z > ±1.96
The test statistic is
z= p1^- p2^ / sqrt ( p^cq^c( 1/n1+ 1/n2)
z= 0.41-0.35 /sqrt( 0.3785*0.6124(1/1000 +1/1100)
z= 0.06 / 0.021036
z= 2.85
Conclusion
The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.
P- value : 0.00466
The result is significant( accept the null hypothesis) for value less than 0.05
Part d:
2012 2010
Sample 1000 1100
Proportions 0.41 0.35
Standard Error √0.41( 0.59)/1000 √0.35( 0.65)/1100

Standard Error for the difference = √0.0155² + 0.01438² =0.0211
p1-p2 ± z* standard error for the difference
0.41-0.35 ± 1.96 *( 0.0211)
0.06 ± 0.041356

The 95 % confidence interval estimate is (-0.018644, 0.10135

Step-by-step explanation:
how can you
change the equation y = mx + b to
shift the graph down?
Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.
The y-intercept is just the constant term in the equation.
As long as the slopes remain the same, the graphs can be
translated up or down by changing the constant value.
Take a look at these lines graphed below.
Notice that y = x + 11 is the same as y = x + 4 but
y = x + 11 is translated 7 units down to get y = x + 4.
MONTRESOR: My dear Fortunato, you are luckily met. How remarkably well you are looking to-day! But I have received a pipe of what passes for Amontillado, and I have my doubts.
FORTUNATO: How? Amontillado? A pipe? Impossible! And in the middle of the carnival!
MONTRESOR: I have my doubts, and I was silly enough to pay the full Amontillado price without consulting you in the matter. You were not to be found, and I was fearful of losing a bargain.
FORTUNATO: Amontillado!
MONTRESOR: I have my doubts.
FORTUNATO: Amontillado!
