Answer:
The conductor checked on the passengers 12 times.
Step-by-step explanation:
To find how many times the conductor checks on the passengers, you must do
8 divided by 2/3
because you have to find how many 2/3 (times checked by conductor) are in 8 hours.
8/1 ÷ 2/3
Switch the two numbers of 2/3 or find the reciprocal which is
3/2
and change ÷ to ×
Now solve.
8/1 x 3/2 = 24/2 (8x3=24 and 1x2=2)
which Simplified is
12/1 or 12
Check your answer:
12/1 x 2/3 = 24/3 = 8
The conductor checked on the passengers 12 times.
Two consecutive vertices of a regular octagon are located at (1, 4) and (4,8). This octagon's perimeter is.....?
Answer:
40 units
Step-by-step explanation:
An octagon is a polygon with 8 sides. A regular octagon is an octagon in which all their sides and angles are equal to each other.
Since the vertices of a regular octagon are located at (1, 4) and (4,8), hence the length of the side is gotten using the formula for calculating the distance between two points [tex]X(x_1,y_1)\ and\ Y (x_2,y_2)[/tex].
[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence:
[tex]Length=\sqrt{(4-1)^2+(8-4)^2}=5\ units[/tex]
Since all the sides of a regular octagon are equal, therefore:
Perimeter = 8 × length = 8 × 5 = 40 units

quotient of Fraction 3 over 4 divided byFraction 3 over 4 .
Answer:
1
Step-by-step explanation:
The equation would look like this: ¾ ÷ ¾
When dividing fractions, you always flip the second one to receive the reciprocal, so the equation now looks like this: ¾ ÷ 4/3
If you cross simplify, the answer will end up being 1.
Alright, -3r + 4(-3r + 2) = 53 how do I break it down and solve??
Answer:
r = -3
Step-by-step explanation:
-3r + 4(-3r +2) = 53
-3r + -12r + 8 = 53
-8 -8
-3r + -12r = 45
-15r = 45
Divide both sides by -15 to get
r = -3
Answer:
r = -3
Step-by-step explanation:
expand 4(-3r+2)
= -12r+8
add similar variables
= -15r+8=53
subtract 8 from both sides
= -15r+8-8=53-8
simplify
= -15r=45
divide 45 by -15
= -3
Find the product.
(36 + 4) (262 – 6 + 4)
Answer:
10,400
Step-by-step explanation:
(36+4)= 40
(262-6+4)= 260
(40)(260)= 10,400
Answer:
10,400
Step-by-step explanation:
Add 36 + 4
40
Now we do the second parentheses.
262 - 6 = 256
256 + 4 = 260
Now we multiply.
40 multiplied by 260 = 10,400

An object is moving at a speed of 6 miles per month. Express this speed in feet per hour
Answer:
44 feet/hour
Step-by-step explanation:
6mi/month(5280ft/1mi)(1month/30days)(1day/24hrs)
Assuming the month has 30 days, object moves at 44 feet/hour. You want all the units to cancel till you get the ones you need, in this case feet/hr.
Juanita has fewer than 80 coins in her coin collection. She noticed that she can divide her coins evenly into groups of 3, 5, 15, or 25.
How many coins does she have?
Find the LCM
3 = 3 times 1
5 = 5 times 1
15 = 5 times 3
25 = 5 times 5
Because they have one 5 and one 3 in common...
5 times 3 times 5 = 75.
She has 75 coins.

For each of the following questions, say whether the random process is a binomial process or not, and explain your answer. As part of your explanation, you will want to comment on the potential validity of each of the four things that must be true for a process to be a binomial process.
a. One basketball player attempts 10 free throws and the number of successful attempts is totalled.
b. Ten different basketball players each attempt 1 free throw and the total number of successful attempts is totalled.
Answer:
a
This process follows is a binomial process
b
This process is not a binomial process
Step-by-step explanation:
Considering the first statement
One basketball player attempts 10 free throws and the number of successful attempts is totaled.
This process is a binomial process because
The number of trials is finite Each trial is independent of the other There is only two possible outcome (make a basket and make no basket The probability of making a basket and not making a basket is constant throughout the trialsOne basketball player attempts 10 free throws and the number of successful attempts is totaled.
This process is not a binomial process because chance that is the probability of success and failure will remain constant throughout the trial is not equal (what this means is that given the number of player is more than on their probability of success and failure will differ.)

Answer:
-8
Step-by-step explanation:
First, rewrite 17/25 and 7/10
so that they have a common denominator.
Answer:
85/50. 35/50
You would times 17/25 by 5 and you would get 85/50 which would simplify to 1 35/50
you would multiply 7/10 by 5 to get 35/50

identify if two lines are coinciding using substitution, elimination, and/or
graphing methods? *
To use substitution to identify if two lines intersect,
1. Rearrange one of the two given equations so that only one variable is on one side of the equation with all other values on the other side of the equation. (if needed)
2. Plug this new equation into the other (in place of a variable)
3. Solve the equation to get the answer of one of the variables
4. Plug this variable into one of the two original equations and solve for the second variable (if needed)
5. Plug both variables back into one of the original equations. If both sides of the equation are equal, the two lines do coincide.
Example:Equation 1: 2x+3y=9
Equation 2: x+8=3
1. Rearrange equation 2
x+8=3
x=3-8
x=-5
2. Plug -5 into the first equation as x
2x+3y=9
2(-5)+3y=9
3. Solve this equation
-10+3y=9
3y=9+10
3y=19
y=[tex]\frac{19}{3}[/tex]
4. Plug x and y back into the first equation
2x+3y=9
2(-5)+3([tex]\frac{19}{3}[/tex])=9
-10+19=9
9=9
Therefore, these two lines do coincide. The point of intersection is (-5,[tex]\frac{19}{3}[/tex]).
Using Elimination:To use elimination to identify if two lines intersect:
1. Multiply one or both of the equations by a factor so both equations have either an x or y coefficient that are equal or opposite of each other (if needed)
2. Add or subtract the two equations to get rid of one variable
3. Solve this new equation for a variable
4. Substitute this variable into one of the two equations to solve for the other
5. Plug both variables back into one of the equations. If both sides are equal, the two lines do coincide.
Example:Equation 1: 2x+3y=4
Equation 2: 4x+2y=3
1. For this specific system of equations, we would multiply the first equation by 2.
2x+3y=4
4x+6y=8
Notice how now, both equations have 4x in them, so we can subtract them:
2. Subtract the new equation from the second original equation
4x+6y=8
- 4x+2y=3
4y=5
3. Solve
4y=5
y=[tex]\frac{5}{4}[/tex]
3. Substitute y back into the first equations (any of the two equations will work) to solve for x
2x+3y=4
2x+3([tex]\frac{5}{4}[/tex])=4
2x+[tex]\frac{15}{4}[/tex]=4
2x=4-[tex]\frac{15}{4}[/tex]
2x=[tex]\frac{16}{4}[/tex]-[tex]\frac{15}{4}[/tex]
2x=[tex]\frac{1}{4}[/tex]
x=[tex]\frac{\frac{1}{4} }{2}[/tex]
x=[tex]\frac{1}{4}*\frac{1}{2}[/tex]
x=[tex]\frac{1}{8}[/tex]
4. Plug both variables back into the first equation (either equation works)
2x+3y=4
2([tex]\frac{1}{8}[/tex])+3([tex]\frac{5}{4}[/tex])=4
[tex]\frac{1}{4}[/tex]+[tex]\frac{15}{4}[/tex]=4
[tex]\frac{16}{4}[/tex]=4
4=4
Since the left side equals the right side, the two lines are coinciding.
Using Graphing Methods:To use graphing methods to identify if two lines coincide, we would just have to graph the line and identify if the two lines meet at a point of intersection/overlap each other.

in 3 1/2 months John collected a debt of $70.00. What was the average amount of debt John collected per month?
Answer:
The average amount of debt John collected per month is $20/ month
Step-by-step explanation:
Given;
total debt collected by John, = $70.00
total number of months, = 3 1/2 months = 7/2 months
The average amount of debt John collected per month is given by;
[tex]Average \ amount \ per \ month = \frac{Total \ amount \ of \ debt}{total \ number \ of \ months} \\\\Average \ amount \ per \ month =\frac{70}{1} *(\frac{2}{7} )\\\\Average \ amount \ per \ month = \$20 \ / month[/tex]
Therefore, the average amount of debt John collected per month is $20/ month
How do you do this question?
Answer: Choice A
Explanation:
The sequence converges to a nonzero value, so as n gets very large, the partial sums will grow forever (since we're effectively adding at least 1 to each term regardless how large n gets)
The reason why [tex]s_n[/tex] approaches 1 is because the 1/n term goes to 0 when n gets very large.
