Savannah sets her watch 10.03 seconds behind and it falls behind another 1.09 seconds everyday. How many days has it been since Savannah last set her watch if the watch is 36.19 seconds behind?
Answer:
24
Step-by-step explanation:
36.19=10.03+1.09x
36.19-10.03=1.09x
26.16=1.09x
x=26.16/1.09
x=24
find the amount in an account after years if invested$5000 at 6% per year and is compounded quarterly
Answer:
The amount of money in the account after t years is given by: [tex]A(t) = 5000(1.015)^{4t}[/tex]
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Invested $5000 at 6% per year and is compounded quarterly
This means, respectively, that [tex]P = 5000, r = 0.06, n = 4[/tex]
So, the amount of money in the account after t years will be given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(t) = 5000(1 + \frac{0.06}{4})^{4t}[/tex]
[tex]A(t) = 5000(1.015)^{4t}[/tex]

The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number
We wish to determine the proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes. A random sample of 242 small- to medium-sized streams is selected and it is found that 55 of them have runoff from hog farms. Which of the following is the value of the parameter of interest in this setting?
a. 0.555
b. 0.03298
c. 0.445
d. The value of the parameter of interest cannot be determined from the given information.
Answer:
The value of the parameter of interest in this setting is:
d. The value of the parameter of interest cannot be determined from the given information.
Step-by-step explanation:
To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina. We also require the population proportion of these streams, which have runoff from hog farms. But in this situation, the information is lacking. Instead, we are given information about the sample, which only produces statistics. For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.
the difference between two numbers is 308 328. if the smaller number is 6 524, what is the larger number?
The larger number is 301804
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
The smaller number =6 524,
The difference between two numbers = 308 328
Now,
Let the missing number be x
x-6524=308328
x=308328-6524
x=301804
Therefore, the larger number of algebra will be 301804.

To eliminate the x terms and solve for y in the fewest steps, by which constants should the equations be multiplied
by before adding the equations together?
First equation: 6x-5y=17
Second equation: 7x + 3y = 11
The first equation should be multiplied by 3 and the second equation by -5.
O The first equation should be multiplied by 3 and the second equation by 5.
O The first equation should be multiplied by 7 and the second equation by -6.
The first equation should be multiplied by 7 and the second equation by 6.
Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.
Simultaneous equation6x - 5y = 17
7x + 3y = 11
Using elimination method
Multiply equation (1) by 3 and (2) by 518x - 15y = 51
35x + 15y = 55
Add the equation18x + 35x = 51 + 55
53x = 106
x = 106/53
x = 2
Substitute x = 2 into6x - 5y = 17
6(2) - 5y = 17
12 - 5y = 17
-5y = 17 - 12
-5y = 5
y = 5/-5
y = -1
Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

According to Wikipedia, the average weight of an adult male in the U.S. is 197.7 pounds with a standard deviation of 18 pounds, while the average adult female weighs 168.7 pounds with a standard deviation of 15 pounds. Both weights vary according to a Normal distribution.
7.) If you randomly selected one adult woman, what is the probability that her weight exceeds (is higher than) 130 pounds?
Suppose you randomly selected one adult male and one adult female from the entire U.S. population. Let the variable D = the difference in their weights (male – female).
8.) Calculate and interpret the mean of D.
9.) Interpret your answer from #8 in context.
10.) Calculate the standard deviation of D.
11.) Calculate the probability that the randomly selected male would weigh less than the randomly selected female.

Answer: See explanation
Step-by-step explanation:
ΔLNM and ΔLKN are 30°- 60°- 90° triangles
We have to find the length of LN before we can find the length of MN.
In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3
Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.
LN = √3 times the shorter leg
3 × √3 = 3√3
LN = 3√3
We now know the length of the longer leg in ΔLNM (3√3)
MN would be 3√3 × √3
3√3 × √3
= 3√9
= 3 × 3 = 9
MN = 9
ΔLKM is also a 30° - 60° - 90° triangle
The short leg is 6 m
The hypotenuse would be 12 m
The longer leg would be 6√3
Perimeter: 6 + 12 + 6√3
The perimeter is 18 + 6√3
Area: 1/2 × b × h
b = 6√3
h = LN = 3√3
6√3 × 3√3
18√9 = 18 × 3 = 54
Area: 54 m²

Hope this helps! :)
Answer: B. (5,11)
Step-by-step explanation:
c = 6 + 1s In this case we know that c is your total cost and s is the number of downloaded songs.
If we were to do it in terms of x and y, y will be c, and x will be s.
Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.
c = 6 + 1(5)
c = 6 + 5
c = 11
Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,
