The value of the investment after 5 years will be $3309.48.
What is compound interest?Compound interest is the addition of interest to the principal sum of a loan or deposit or interest on interest plus interest.
In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor. It differs from a fee that the borrower may pay to the lender or a third party.
The value of the investment after 5 years will be,
[tex]A = P[(1 + \dfrac{r}{100} )^{nt}]\\A = 2800[(1+0.034)^{5}[/tex]
A = $3309.48

A survey was conducted of 371 teenagers. Thirty-five percent of the teenagers said they occasionally smoked cigarettes.
A. Find the margin of error for this survey
B. Write a statement about the percentage of teenagers who occasionally smoke cigarettes
a. The margin of error for this survey is of: 4.85%.
b. The 95% confidence interval for the percentage of teenagers who occasionally smoke cigarettes is of:
(30.15%, 39.85%).
How to obtain the confidence interval?Confidence intervals for proportions are obtained using the z-distribution.
The bounds of the interval are given as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The sample size and the estimate in this problem are given as follows:
[tex]n = 371, \pi = 0.35[/tex]
The margin of error is given as follows:
[tex]M = 1.96\sqrt{\frac{0.35(0.65)}{371}} = 0.0485[/tex]
As a percentage, it is of 4.85%.
Then the bounds of the interval are given by the estimate plus/minus the margin of error, hence:

f(x)=1314+303 Inx
A) this function predicts for the percent of outpatient surgeries in 1996 IS
x = 1996-1900 = 96.
So f(96) = -1314 + 303 ln(96) =68.99 %
b) f(x) = 60
60 = -1314 + 303 ln(x)
ln x = (1314+60)/303 = 4.53
x = 92.75.
Hence, the percent of outpatient surgeries in 1996 is 68.99 % and outpatient surgeries reach is 1992.

Which situation below represents a 30% decrease?
from 50 to 35 OR from 30 to 27
Answer: 50-35
Step-by-step explanation:
Because if you calculate it, 50x70% or 50x0.7 is 35. I multiply bt 70% not 30% because you are trying to find the amount after the 30% decrease, meaning it is 70% of the orginal value.
Answer:
50 to 35
Step-by-step explanation:
[tex]\frac{30}{27} =\frac{100}{y}[/tex]
30y = 2700
y = 90
27 is 90% of 30.
[tex]\frac{50}{35}=\frac{100}{y}[/tex]
50y = 3500

Using Graphs to compare two quantities.
What is the value of Y?
(Please help me with this question.)
Answer:
x = 8
y = 36
Step-by-step explanation:
The triangle shown in the image is an isosceles triangle.
We can find the value of x using the above mentioned information:
∠B = ∠A
5x = 40 divide both sides by 5
x = 8
The sum of interior angles in a triangle is equal to 180°.
Since ∠B and ∠C are both 40°:
40 + 40 + 3y - 8 = 180 add/subtract like terms
72 + 3y = 180 subtract 73 from both sides
3y = 108 divide both sides by 3
y = 36

The length of a rectangle is twice its width. How many times as long as the width of the rectangle is the perimeter of the rectangle?
Answer:
perimeter is 6 times as long as the width
Step-by-step explanation:
let width be w then length l = 2w
perimeter (P) of a rectangle is calculated as
P = 2(l + w )
= 2(2w + w)
= 2(3w)
= 6w
Perimeter is 6 times as long as the width
The width of the rectangle is (1/6) times long as the perimeter of the rectangle.
What is the area of a rectangle?The area of a rectangle is given by -
A{R} = Length x Breadth
A{R} = L x B
Given is the length of a rectangle is twice its width.
Assume the width of the rectangle be [x] units. Then, the length will be [2x] units. For the width of the rectangle to be as long as the perimeter of the rectangle -
{P} = 2{L + B} = 2{x + 2x} = 6x
Now -
{w} = x
So, we can write that -
{P} = 6{w}
{w} = {1/6}{P}
Therefore, the width of the rectangle is (1/6) times long as the perimeter of the rectangle.

A regression equation is utilized in details to figure out what relationship, if any, exists between sets of information. For instance, assuming that you measure a kid's level consistently you could find that they develop around 3 inches a year. That pattern (growing three inches a year) can be displayed with a regression equation.
According to question:
The remarkable relapse condition is the dramatic capability that best fits the arrangement of information and it is given in the structure:
y = a · bˣ
where:
a = beginning worth of the model
b = remarkable develop or rot
x = time elapsed all along
For our situation,
y = 9.92 · (0.8208)ˣ
where:
a = 9.92
b = 0.8208
Since 0 < b < 1 we have an outstanding rot, affirming that the quantity of VHS is diminishing with time.
We can then utilize this condition to gather the quantity of VHS motion pictures in 2011.
As something first, compute how long all along (2000) would pass:
x = 2011 - 2000 = 11
Presently, substitute this worth in the situation:
y = 9.92 · (0.8208)¹¹

Alexandra grew 9 flowers with 3 seed packets. How many seed packets does Alexandra need to have a total of 18 flowers in her garden? Solve using unit rates.
Answer:
The answer is 6, I am going to give you a explanation just in case you need one.
Step-by-step explanation:
We are going to refer seed packets as SP just to make it more simple. And flowers F this is just to make it easier on ourselves.
Ok since we know that in order to plant 9 F we need 3 SP.
If we do the equation correctly we should get
3 SP × ? = 9
In order to do this there is two ways I am going with the easier one we just have to add 3 to 3 until we get 9 ok so 3 + 3 = 6 so lets add more 3's 6 + 3 = 9 great so this means 3 + 3 + 3 = 9. Now if you noticed he had three three's which means our equation now is
3 SP × 3 = 9
Now that we are done with the first part it should just get easier from here.
We know that each SP has 3 F to grow and each SP has 9 F to grow we just have to do 9 + 9 which gives us 18.
Therefore the answer is 2 SP needed to plant 18 flowers.

What is the slope of a line parallel to the line whose equation is
8x-6y=-24
The slope of a line parallel to the line 8x - 6y = -24 is 4/3.
What is slope of a line parallel to the line whose equation is given?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation of the line.
8x - 6y = -24
First, rewrite in slope-intercept form.
8x - 6y = -24
Solve for y
8x + 24 = 6y
6y = 8x + 24
y = (8/6)x + 24/6
y = (4/3) + 4
Now, from the slope-intercept form;
y = mx + b
Where m is the slope
Slope of the line y = (4/3) + 4 will be
m = 4/3
All line parallel to the line y = (4/3) + 4 must have the same slope.
Hence, the slope of a parallel line to the line y = (4/3) + 4 will be;
m_parallel = 4/3
