Answer:
1) 202.52
2) P107089
Step-by-step explanation:
Compound interest is calculated as
A = P (1 + r/n)^(nt), where
A = compounded interest
P = present value
r = interest
n = number of times interest applied
t = time taken
A = 200 (1 + 0.25%/30)^(30 * 5)
A = 200 (1 + 8.3*10^-5)^150
A = 200 * 1.0126
A = 202.52
Present Value Annuity Due is usually given by the formula
P = c*((1-(1+ i)^(-n))/i)*(1 + i ), where
P is the present value
C is the Cash flow per period
i is the interest rate and
n is the number of payments
P = 10000*((1-(1+ 12/1200)^(-1*12))/(12/1200))*(1+12/1200)
P = 113676
Also, it's worthy of note that
Effective Annual Rate = [(1 +stated rate/no. of compounding periods) ^no of compounding periods - 1]* 100
EAR = ((1+12/(12*100))^12-1)*100
EAR = 12.68%
And lastly, the
Future value = present value*(1+ rate)^time
113676 = Present value*(1+0.1268)^0.5
Present Value = 113676 / 1.1268^0.5
Present Value = 113676 / 1.0615
Present value = 107089
A 95% confidence interval for the proportion of American adults who believe that regular exercise is important was computed to be [0.726, 0.780]. Given this confidence interval, which of the following values are reasonable estimates for the proportion of all American adults who believe that regular exercise is important (i.e., the population proportion).
a. 0.730
b. 0.765
c. 0.770
d. 0.795
Using confidence interval concepts, it is found that the reasonable estimate for the proportion of all American adults who believe that regular exercise is important is of 0.753.
What is a confidence interval?
It is the range in which a parameter is expected to be given a confidence level, has format (a,b), and the point estimate of the parameter is the mean between a and b.
In this problem, the interval is [0.726, 0.780], hence, the estimate is of:
(0.726 + 0.78)/2 = 0.753

ten is equal to two times a number plus 3.6.
Answer:
3.2
Step-by-step explanation:
Make an equation!
10=2x+3.6
isolate the variable:
6.4=2x
divide by 2
3.2=x
i hope this helps!
Answer:
3.2
Step-by-step explanation:
10= 2x + 3.6
subtract 3.6 from both sides
2x = 6.4
divide both sides by 2
x = 3.2
Question... factor 28+4x
Answer:
4(7 + x)
Step-by-step explanation:
28 + 4x
4 ⋅ 7 + 4x
4(7 + x)
good luck hope this helps :)
Find the greatest common factor for the terms involved in the polynomial.
In this case, the greatest common factor between 28 and 4 is 4.
So a 4 factors out of this polynomial.
That leaves us with each term divided by 4
inside a set of parentheses.
So we have 4(7 + x).
Now you can check your answer by distributing the 4 through
the parentheses and you will end up with your original polynomial.

Question 15
Tessa made 14 out of 22 free throw attempts in the first half of practice and 22 out of 28 attempts in the second half of practice. What is her free throw average for the whole practice, written as a decimal? PLEASE HELP, I NEED IT QUICK!! 30 POINTS FOR IT
Answer:
0.71
Step-by-step explanation:
1st attempt = [tex]\frac{14}{22} = 63%[/tex]%
2nd attempt = [tex]\frac{22}{28} = 79%[/tex]%
To get the average of something, find the sum of the numbers and then divided the sum by the total number of values there are.
⇒ 63 + 79 = 142
⇒ 142 / 2 = 71%
⇒ 71% = .71
Find the value of csc Θ if cos Θ = - 3/5 180° ≤ Θ < 270°
csc =
Answer:
csc Θ = - 5/4
Step-by-step explanation:
Consider a coordinate plane. As the range is from 180 to 270, we find that the triangle to be created should be in the 3rd quadrant.
cos Θ = - 3/5
5 ---> hypotenuse
- 3 --> adjacent side
Θ = angle is between the respective sides
We have to find the length of the remaining side, which would be the following:
- √5^2 - (-3)^2 = - √25 - 9
= - √16
= - 4
Remember csc Θ = Hypotenuse/Opposite = 5/-4 = - 5/4

Measure these angles.
a)
b)
Answer:
Step-by-step explanation:
Angle A = 55 degrees. Angle B = 61 degrees.
The measure for part a is 55 degree.
The measure for part b is 61 degree.
What is Acute Angle?An acute angle is one that is smaller than the right angle. In other terms, an acute angle is formed by an angle less than 90 degrees. Polygons with at least one sharp angle include triangles, parallelograms, trapezoids, and so on.
An acute angle is one that is smaller than 90 degrees in length. This is a smaller angle than the right angle (which is equal to 90 degrees).
Given:
from the Figure we can see that the both angles are less than 90 degree i.e., Right angle.
Also, we know that Angles which are less than 90 degree is acute angle.
So, the both angles are less than 90.
The measure for part a is 55 degree.
and, the measure for part a is 61 degree.

If there are 125 boxes of prescription bottle labels at the beginning of inventory cycle, and 25 3/4 remain ,how many boxes of labels remain?
Answer:
Rounded to the nearest integer, 32 boxes of labels remain at the end of the inventory cycle.
Step-by-step explanation:
Given that there are 125 boxes of prescription bottle labels at the beginning of the inventory cycle, and 25 3/4 remain at the end of it, to determine how many boxes of labels remain the following calculation must be performed:
3/4 = 0.75 + 25 = 25.75
125 x 25.75 / 100 = X
3218.75 / 100 = X
32.1875 = X
Thus, rounded to the nearest integer, 32 boxes of labels remain at the end of the inventory cycle.

Answer: Point D
===============================================================
Explanation:
We start at the lower left corner, which is the location (0,0)
Then we move to the right four spaces to arrive at (4,0) which is where point L is at right now.
Lastly, we move 5 units up to get to (4,5) which is where point D is located.
Each (x,y) point can be thought of as an address so we can quickly communicate a point's location to someone, even if they don't have the visual in front of them. You can think of it like latitude and longitude. The game of battleship uses a similar concept, but it uses letters as the first coordinate.
