A small combination lock on a suitcase has 6 wheels, each labeled with the 10 digits 0 to 9.
How many digit combinations are possible if no digit is repeated? If digits can be repeated? If successive digits must be different?,
There will be, 590490 possible combinations.
What is combination?The number of different groups which can be formed from the available things can be calculated using combinations.
Given that, A small combination lock on a suitcase has 6 wheels, each labelled with the 10 digits 0 to 9.
We have 10 for the first wheel, but second wheel only has 9 options because 2nd number can't be the same as first. The third and fourth wheels also has 9 options for the same reason.
10x9x9x9x9x9 = 590490 combinations
Hence, There will be, 590490 possible combinations.

Find the equatio of the line tht contains the point (5,6) and is perpendicualr to the line 4x+2y=2
Final answer:
The equation of the line that passes through the point (5,6) and is perpendicular to the line 4x+2y=2 is y = 1/2x + 7/2.
Explanation:
The question asks us to find the equation of a line that passes through a given point and is perpendicular to a given line. To solve this, we first need to determine the slope of the given line, then find the perpendicular slope, and finally, use the point-slope form of a line to write the equation for our new line.
Here are the steps:
Find the slope of the given line. For the equation 4x + 2y = 2, we rearrange it to slope-intercept form (y=mx+b), which gives us y = -2x + 1. The slope is -2.
Since we want a line that is perpendicular to the given line, we need the negative reciprocal of -2, which is 1/2.
Now we use the point-slope form of a line, y-y1 = m(x-x1), with point (5,6) and slope 1/2. This gives us y - 6 = 1/2(x - 5).
Solving for y to get the slope-intercept form, we multiply both sides by 2 to get rid of the fraction: 2y - 12 = x - 5, and then solve for y: y = 1/2x + 7/2.
The equation of the line that contains the point (5,6) and is perpendicular to the line 4x+2y=2 is y = 1/2x + 7/2.

For which data representation is the median the better measure of center
Answer with explanation:
Mean is sum of all the observation divided by total number of observation, where as median is middlemost observation of the data set, while mode is most occurring variate or data value in the data set.
1. Variate or Data set which is represented in Histogram is
3,8,4,8,3
Arranging it in ascending order, we get
3,3,4,8,8
Data is skewed right.So, Mean >Median>Mode
Mean =5.2
Number of observation is 5. So,Median will be Middle term,that is third term equal to 4.
Mode =3 or ,8 which will be equal to 3,as data is skewed right.
→Mean gives better representation of data set,because, 5.2-3=2.2 and, 8-5.2=2.8
2. Variate or Data set which is represented through dots is
2, 2, 3,5,5
Arranging it in ascending order, we get
2,2,3,5,5
Data is skewed right.So, Mean >Median>Mode
Mean=3.4
Number of observation is 5. So,Median will be Middle term,that is third term equal to 3.
Mode =2 or 5 which will be equal to 2,as data is skewed right.
→Mean gives better representation of data set,because, 3.4-2=1.4 and, 5-3.4=1.6
3. Variate or Data set which is represented in Histogram is
6,2,6,2,6
Arranging it in ascending order, we get
2,2,6,6,6
Data is skewed left.So, Mean <Median<Mode
Mean=4.4
Number of observation is 5. So,Median will be Middle term,that is third term equal to 6.
Mode =6
→Mode gives better representation of data set.
4.Variate or Data set which is represented through dots is
1,3,4,3,1
Arranging it in ascending order, we get
1,1,3,3,4
Data is skewed left.So, Mean <Median<Mode
Mean=2.4
Number of observation is 5. So,Median will be Middle term,that is third term equal to 3.
Mode =1 or 3,data is skewed left,so mode =3
Here, in this data set, both mode and median are better measure of center than Mean,as there are two modes in the data set, so choosing median as measure of center,because data is skewed left,
For ,Option 4: Median is the better measure of center.

The sum of 555 consecutive integers is 505505505. What is the third number in this sequence?
Answer: The answer is 101!
Step-by-step explanation:
Call the first number in the sequence x
The next integer in the sequence is x + 1
The sum of the 5 consecutive integers is:
x+ (x + 1)+ (x + 2)+ (x + 3)+ (x + 4) = 505
5x + 10= 505
5x = 495
x = 99
Since x is the first number, x + 2 is the third integer.
Thus, the third number in the sequence is 101

Which ordered pair (a, b) is a solution to the given system of linear equations?
A (1, 7)
B (3, 1)
C (11, –23)
D (23, –11)
Answer:
C. (11,-23)
Step-by-step explanation:
The given equations are
[tex]3a+b=10[/tex].....................equation 1
[tex]-4a-2b=2[/tex]...................equation 2
Multiply first equation by 2
[tex]6a+2b=20[/tex]
Now add this new equation to 2nd equation
[tex]6a-4a +2b-2b = 20+2[/tex]
[tex]2a = 22[/tex]
Divide both sides by 2
[tex]a=11[/tex]
We got a=11 , plug this value in anyone equation
3(11)+b=10[tex][/tex]
[tex]33+b=10[/tex]
Subtract 33 from both sides
[tex]b=-23[/tex]
So solution is (a,b) = ( 11,-23)

Step-by-step explanation:
We have been given a line on coordinate plane. We are asked to find the equation of our given line.
First of all, we will find slope of our given line using points [tex](-2,3)[/tex] and [tex](0,-1)[/tex] in slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], where,
[tex]y_2-y_1[/tex] = Difference between two y-coordinates,
[tex]x_2-x_1[/tex] = Difference between two x-coordinates of same y-coordinates.
Upon substituting our given values in slope formula, we will get:
[tex]m=\frac{-1-3}{0--2}[/tex]
[tex]m=\frac{-4}{0+2}[/tex]
[tex]m=\frac{-4}{2}[/tex]
[tex]m=-2[/tex]
Now, we will use slope-intercept form of equation [tex]y=mx+b[/tex], where,
m = Slope of line,
b = The y-intercept.
Upon looking at our given graph, we can see that y-intercept is [tex]-1[/tex].
Therefore our required equation would be [tex]y=-2x-1[/tex] and option D is the correct choice.

A rectangle basin is being filled with water. The basin is 7 feet long, 12 feet wide, and 4 feet high. How much water is going to be needed to fill the basin.
A rectangular piece of sheet metal has a length that is 6 in. less than twice the width. a square piece 3 in. on a side is cut from each corner. the sides are then turned up to form an uncovered box of volume 1014 in. cubed find the length and width of the original piece of metal.
Determine the dimensions of the metal sheet by setting up and solving equations based on the given volume of the box and the relationship between its length and width.
Explanation:This problem can be tackled by using a bit of algebra and understanding volume calculations. We can use the equation for the volume of a box which is V=length*width*height. The problem gave us the volume of 1014 cu in. When a 3 in. square is cut from each corner of the rectangular piece of metal, the sides fold up to form the box, the height of the box becomes 3 in. This means we're missing the length and width of the box to solve for volume.
Since the length equals to twice the width minus 6 in., we can express the length as 2W - 6. Substituting these into the volume equation we get: 1014 = (2W - 6)(W)(3) which when simplified gives W, the width of the metal piece. Then substitute W into the length formula 2W - 6 to solve for the length.
