How long will it take for a sum of money, invested at 5% compounded annually, to double in value?
To determine the time needed for an investment to double at a 5% compounded annual rate, apply the Rule of 72 by dividing 72 by the interest rate, resulting in approximately 14.4 years.
The question pertains to the time it takes for an investment to double in value with compound interest. To calculate this, we can use the Rule of 72. This rule states that you can approximate the number of years it'll take for an investment to double by dividing 72 by the annual interest rate. In this case, with a 5% interest rate, it would be calculated as 72 \/ 5, which equals approximately 14.4 years.
Here's a step-by-step explanation:
Apply the Rule of 72 by dividing 72 by the interest rate: 72 ÷ 5 = 14.4.
Therefore, it will take roughly 14.4 years for the sum of money to double at an annual compounded interest rate of 5%.
This is a quick and efficient way to estimate the power of compound interest and make informed investment decisions.

If male and female college students work an average of 15 hours per week during the school year and the standard deviation is 5.4 for male students and 2.3 for female students, what may we conclude?
Answer: the male sample is more spread than the female sample
Step-by-step explanation:
The mean is the same for both genres, but the standard deviation form males is bigger than the one for females.
This means that the data of the male students is more spread than the female data (so there are more male students that study more hours, but there also are more male students that study less hours).
So the general conclusion is that the male sample is more spread than the female sample

What is the equation of the line that contains the points (3, –6) and (–3, 0)?
A.
y = x – 3
B.
y = –x – 3
C.
y = –x + 3
D.
y = x + 3
To determine the equation of a line given two points, calculate the slope and then use one point to write the equation in slope-intercept form. The equation of the line through (3, -6) and (-3, 0) is B. y = -x - 3.
To find the equation of the line that contains the points (3,
-6) and (
-3, 0), we need to calculate the slope (m) of the line using the slope formula:
m = (y2 - y1) / (x2 - x1).
Plugging in the given points:
m = (0 - (-6)) / (-3 - 3)
m = 6 / -6
m = -1.
With the slope now known, we can use one of the points and the slope to write the equation of the line in point-slope form (y - y1) = m(x - x1) and then convert it to slope-intercept form (y = mx + b). Let's use the point (-3, 0):
y - 0 = -1(x + 3)
y = -1x - 3.
Therefore, the correct equation of the line is B. y =
-x - 3.

The ice rink sold 95 tickets for the afternoon skating session, for a total of $828. General admission tickets cost $10 each and youth tickets cost $8 each. How many general admission tickets and how many youth tickets were sold?
By solving the system of linear equations formed from the scenario given, we find that the ice rink sold 34 general admission tickets and 61 youth tickets during the afternoon skating session.
Explanation:This problem is a simple linear algebra problem. We can represent the total number of tickets with the variable x (for the general admission tickets) and y (for the youth tickets). The scenario provides us with two equations:
The total number of tickets sold is 95, so x + y = 95.The total amount of money collected is $828, so 10x + 8y = 828.To solve the system of equations, we can multiply the first equation by 8 to have both equations involving '8y', which gives us 8x + 8y = 760.
Subtracting the first modified equation from the second gives: 2x = 68. Therefore, solving for x gives us x = 34. That means, there were 34 general admission tickets sold.
Substitute x=34 into x + y = 95, we get 34 + y = 95, which simplifies to, y = 61. That means, there were 61 youth tickets sold.

Kat has 19 coins, all quarters and dimes, that are worth a total of $4. The system of equations that can be used to find the number of quarters, q, and the number of dimes, d, she has is shown.
q + d = 19
0.25q + 0.1d = 4
How many quarters does she have?
4
5
14
15
To find the number of quarters, solve the system of equations. Kat has 14 quarters.
Explanation:To find the number of quarters Kat has, we can solve the system of equations given. The first equation states that the number of quarters (q) and the number of dimes (d) add up to 19.
The second equation represents the total value of the coins, where each quarter is worth $0.25 and each dime is worth $0.10.
By solving this system of equations, we can determine the value of q, which represents the number of quarters.
Using the first equation, we can solve for d by subtracting q from both sides: d = 19 - q.
Substituting this value of d into the second equation, we get: 0.25q + 0.1(19 - q) = 4.
Solving this equation, we find q = 14. Therefore, Kat has 14 quarters.

The solution of the equation is x = ±3. 162.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.
An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.
Given:
x² = 10
Now to solve the above equation we have to take the square root on both side, we get
√x² = √10
x= ±√10
x= ±3. 162 ( because root provides two values one is positive and other is negative)
Hence, the value of x is ±3. 162.

Ivan was given two data sets, one without an outlier and one with an outlier.
Data without an outlier: 108, 113, 105, 118, 124, 121, 109
Data with an outlier: 108, 113, 105, 118, 124, 121, 109, 61
How is the median affected by the outlier?
Answer:
Median is decreased by the outlier or Outlier made median lower.
Step-by-step explanation:
First we calculate median of the data without an outlier:
Data in Ascending or increasing order ,
105 , 108 , 109 , 113 , 118 , 121 , 124
Now there are 7 terms so
Median = [tex]\frac{7+1}{2}^{th}\:term[/tex] = 4th term = 113
Now we find median of the data with outlier:
Data in ascending or descending order,
61 , 105 , 108 , 109 , 113 , 118 , 121 , 124
here no of terms are 8.
So, Median = [tex]\frac{(\frac{8}{2})^{th}+(\frac{8}{2}+1)^{th}}{2}[/tex]
= [tex]\frac{4^{th}+5^{th}}{2}=\frac{109+113}{2}[/tex]
= 111
So, Median is decreased by the outlier or Outlier made median lower.
Find the probability when a couple has 6 children at at least one of them is a boy
The probability when a couple has 6 children at at least one of them is a boy is 63/64
First step
Probability of all 6 girls=(1/2)^6
Probability of all 6 girls = 1/64
Second step is to determine the probability at least one of them is a boy
Let at least one boy means not all girls
Hence:
P(all girls)+P(not all girls)=1
P(at least 1 boy)=1-P(all girls)
P(at least 1 boy)=1-1/64
P(at least 1 boy)=63/64

Crystal charges a flat fee of $10 plus an additional $5 per hour to babysit given the situation what is the range
Answer:
perhaps $10 to $10,810
Step-by-step explanation:
We assume Crystal may be willing to babysit for a period of up to 3 months (90 days), so 90×24 = 2160 hours. Her hourly fee for that period will be ...
... (2160 hours) × ($5/hour) = $10,800
That amount added her $10 initial charge may represent the upper limit of her pay. The lower limit will be the $10 initial charge.
_____
Comment on the question
Since no upper limit on hours is given, we conclude the problem is not well-specified.
We can make a variety of different assumptions regarding the upper limit of babysitting time.
We might choose to consider this a daily charge, so the upper limit is $130 per day. We might consider that Crystal is willing to babysit while the child's parents are on a 2-week vacation. We might consider that Crystal is willing to babysit for the duration of her summer vacation from school (about 3 months). This is the assumption we use here.Camelle manages her soccer team.
