Let's say we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow. What is the probability of picking a yellow marble, returning it to the box, and then picking a blue marble?
1/12
1/30
1/36
1/11
Answer:
1/12
Step-by-step explanation:
you have 1/6 chance at drawing it once (one yellow marble, six total), so 1/12 to draw it twice.
The probability of picking a yellow marble, returning it to the box, and then picking a blue marble will be 1/36. Option C is correct.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow.
We have to find the probability of picking a yellow marble, returning it to the box, and then picking a blue marble.
The probability of picking a yellow marble, returning it to the box, and then picking a blue marble is obtained as,
=1/6 × 1/6
=1/36
Thus the probability of picking a yellow marble, returning it to the box, and then picking a blue marble will be 1/36. Option C is correct.

Answer:
The interest charged is $7.49.
After 29 days, Travis paid a total of $607.49
Step-by-step explanation:
Travis obtained a cash advance for $600.
The interest rate is 0.04305% per day.
The simple interest rate formula is given by:
[tex]I=Prt[/tex]
Where I is the interest, P is the initial amount, r is the rate, and t is the time (in this case in days).
Our initial amount P is $600.
Our interest rate r is 0.04305% or (moving the decimal two places to the left) 0.0004305.
Since Travis repaid the loan after 29 days, our t is 29.
Hence, our interest is:
[tex]I=600(0.0004305)(29)=7.4907[/tex]
So, the interest charged is about $7.49.
So, after 29 days, Travis paid a total of the original $600 plus an interest of $7.49 for a total of $607.49
Answer:
The interest charged is $7.49.
After 29 days, Travis paid a total of $607.49
Step-by-step explanation:
Travis obtained a cash advance for $600.
The interest rate is 0.04305% per day.
The simple interest rate formula is given by:
→ I=Prt
Where I is the interest, P is the initial amount, r is the rate, and t is the time (in this case in days).
Our initial amount P is $600.
Our interest rate r is 0.04305% or (moving the decimal two places to the left) 0.0004305.
Since Travis repaid the loan after 29 days, our t is 29.
Hence, our interest is:
→ I=600(0.0004305)(29)=7.4907
So, the interest charged is about $7.49.So, the interest charged is about $7.49.So, after 29 days, Travis paid a total of the original 600 plus an interest of 7.49 for a total of $607.49If the supplement of <1 is 32º less than the measure of <1, what is m<1? a 1060 b 74o c 61o d 29o
Answer:
a. 106 degrees
Step-by-step explanation:
m=measure of angle 1; m-32 degrees=measure of supplement
m+(m-32 degrees)=180 degrees Add 32 degrees to each side.
2m=212 degrees Divide each side by 2
m=106 degrees ANSWER: The measure of angle 1 is 106 degrees
CHECK:
106+(106-32)=180
106+74=180
180=180
4.) Fill in the table to show a proportional relationship and then identify the
constant of proportionality for the cost to the number of yoga classes. In
the answer box, please list the constant of proportionality.
Answer/Step-by-step explanation:
✔️Number of Yoga classes = x
Cost ($) = y
Constant of proportionality (k) = y/x
Using the pair form the table of values given, (4, 60), find the constant of proportionality:
✅k = 60/4 = 15
Equation that represents the relationship between x and y is:
y = 15x
✔️Let's complete the table.
✅When number of yoga classes (x) = 2:
Substitute x = 2 into y = 15x
Thus,
y = 15*2 = 30
That is, 2 Yoga classes will cost $30
✅When number of yoga classes (x) = 6:
Substitute x = 6 into y = 15x
Thus,
y = 15*6 = 90
That is, 6 Yoga classes will cost $90
✅When number of yoga classes (x) = 8:
Substitute x = 8 into y = 15x
Thus,
y = 15*8 = 30
That is, 8 Yoga classes will cost $120

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not existTo solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms.

mistakes mistakes on a page.
Answer:
0.43
Step-by-step explanation:
Formatting the Given data into a probability distribution table :
X : ____ 0 __ 1 ___ 2 ____ 3 _____ 4 ____ 5
P(x) : _0.09_0.11 _ 0.24 _0.21 ___ 0.17 __ 0.05
Probability of making 3 or more mistakes :
P(x ≥ 3) = P(x = 3) + P(x = 4) + P(x = 5)
P(x ≥ 3) = 0.21 + 0.17 + 0.05
P(x ≥ 3) = 0.43

Please I need this ASAP! A couple needs to get a loan of $5,000 and has to choose between three options. • Option A: 2 1/4% compounded quarterly (every 3 monins) o Option B: 3% compounded every 4 months o Option C: 4 1/2% compounded semi-annually If they make no payments for 5 years, which option will give them the least amount owed after 5 years? Use a mathematical model for each option to explain your choice.
Therefore, option A will result in the least amount owed after 5 years.
What is percent?Percent is a way of expressing a number as a fraction of 100. The symbol used for percent is "%". For example, 50% is equivalent to 50/100 or 0.5. Percentages are commonly used to express rates, ratios, and changes in quantity over time.
Here,
To determine which option will result in the least amount owed after 5 years, we need to calculate the total amount owed for each option at the end of the 5-year period. We can use the formula A=P(1+r/n)^(nt) to calculate the total amount owed, where A is the final amount owed, P is the principal (in this case $5,000), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time period in years.
Option A: 2 1/4% compounded quarterly (every 3 months)
The annual interest rate is 2.25%. Since interest is compounded quarterly, n=4. The time period is 5 years, so t=5. Plugging these values into the formula, we get:
A = [tex]5000(1+0.0225/4)^{(4*5)}[/tex]
= $5,827.05
Option B: 3% compounded every 4 months
The annual interest rate is also 3%, but interest is compounded every 4 months. To calculate the effective interest rate per year, we need to convert the compounding period to years. Since there are 3 compounding periods per year (4 months each), the effective annual interest rate is:
(1+0.03/3)³ - 1 = 0.0304 or 3.04%
Using the formula with these values, we get:
A = 5000(1+0.0304)⁵
= $6,079.28
Option C: 4 1/2% compounded semi-annually
The annual interest rate is 4.5%. Since interest is compounded semi-annually (twice per year), n=2. Plugging in the values, we get:
A = [tex]5000(1+0.045/2)x^{(2*5) }[/tex]
= $6,200.92

Write a function using function notation to describe each situation. Find a reasonably domain and range for each function. A newspaper charges $3 per line for the first 4 lines plus a $20 fee to advertize.
Answer:
The answer is below
Step-by-step explanation:
The domain of a function is the set of all independent variables for the function while the range of a function is the set of all possible dependent variables.
Let x represent the number of newspaper lines and f(x) be the charges for advertisement. x is the independent variable and f(x) is the dependent variable.
Since the newspaper charges $3 per line for the first 4 lines plus a $20 fee to advertise, the function is given as:
f(x) = 3x + 20 for 0 < x < 4
But for more than four lines, the charges is given as:
f(x) = 12 + 20 = 32 4 < x < ∞
Therefore, the domain and range of the function is:
Domain = (0, ∞)
Range = (20, 32}
