Let n be a positive integer. Consider the  n+1 integers 1,11, 111,1111,... (where the last integer in this list is the integer with n+1 - 1s in its decimal expansion).

Note that there are n possible remainders when an integer is divided by n. Because there are n+1 integers in this list, by the pigeonhole principle there must be two with the same remainder when divided by n. The larger of these integers the smaller one is a multiple of n, which has a decimal expansion consisting entirely of 0s and 1s.

For example, take n=7

we have, 1,11, 111,1111,...,11111111

The remainder possible when any number is divided by 7 is 0,1,2,3,4,5,6

These are the remainders when the numbers in the first list are divided by 7 gives 1,4,6,5,2,0,1,4.

Now you can see that we have 7 pigeonholes {0,1,2,3,4,5,6} and 8 pigeons {1,11, 111,1111,...,11111111} so there needs to be at least one pigeonhole where 2 pigeons will reside.

In this case, we have 11%7=4 and 11111111%7=4

Their difference, i.e. 11111111-11=11111100 is divisible by 7.

Given  number is 71830.

The last part:  830 is same on both lines.

We need to represent 71000 in different way, instead of 7 ten thousands and 1 thousands we have 6 ten thousands then we need:

It is 11 thousands.

Answer:

11,000 (or) 11 thousands

Step-by-step explanation:

Now we have to,

→ find the missing number.

→ Let the number be x.

Forming the equation,

→ 60,000 + x + 800 + 30 = 71,830

Then the value of x will be,

→ 60,000 + x + 800 + 30 = 71,830

→ x + 60,830 = 71,830

→ x = 71,830 - 60,830

→ [ x = 11,000 ]

Hence, the value of x is 11,000.

Step-by-step explanation:

Given the equation for a line, y +3 = (x -6), you want to identify the slope and a point on the line, then graph it.

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Comparing this to the given equation, you can see ...

This tells you the slope is 1 and a point on the line is (6, -3).

You graph this equation by plotting point (6, -3) and drawing a line through it that goes up 1 unit for each 1 unit to the right. A graph is attached.

__

Additional comment

If you like, you can rearrange the equation to slope-intercept form by subtracting 3:

  y +3 -3 = (x -6) -3

  y = x -9

This tells you another point is -9 on the y-axis.

The position of the √7 on the number line is slightly right of the 2.6.

The units digit of the double factorial notation is the units digit of the product of all the even integers from 2 to 8, which is 8! The units digit of 8! is 8, so the answer is 8.

Factorials are mathematical operations symbolized by an exclamation point following a number. To find the factorial of a number, such as 5, write it down as 5! then multiply it by all the positive integers less than 5, including 1. Therefore, 5! is equivalent to 5 x 4 x 3 x 2 x 1, or 120. Factorials are frequently employed in mathematical equations and computations, especially in probability and statistics, where they are used to calculate the number of combinations or permutations that may be made from a given collection of numbers or variables. For example, if you had 5 distinct objects and want to determine how many various combinations , you used the factorial of 5.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

Step-by-step explanation:

we want to find the number of hours (or rather days) until only 4.25% of the drives fail.

that means for an exponential distribution we have

P(X < x) = 1 - e^(-Lx)

L = 1/mean = 1/12500

and we need to find x, so that P(X <x) = 0.0425 (that is 4.25% converted into a probability).

so, we get

0.0425 = 1 - e^(-x/12500)

0.0425 - 1 = -e^(-x/12500)

-0.9575 = -e^(-x/12500)

0.9575 = e^(‐x/12500)

ln(0.9575) = -x/12500

-x = ln(0.9575)×12500

x = -ln(0.9575)×12500 = - -0.043429558...×12500 =

Step-by-step explanation:

Compute the Euclidean distance between the following points:

p_1 = (-2, 3) and p_2 = (5, -1)

The Euclidean distance between points (x_1, y_1) and (x_2, y_2) is:

sqrt((x_1 - x_2)^2 + (y_1 - y_2)^2)

Substitute (x_1, y_1) = (-2, 3) and (x_2, y_2) = (5, -1):

= sqrt((-2 - 5)^2 + (--1 + 3)^2)

(-1)^2 = 1:

= sqrt((-2 - 5)^2 + (1 + 3)^2)

-2 - 5 = -(2 + 5):

= sqrt((-(2 + 5))^2 + (3 + 1)^2)

2 + 5 = 7:

= sqrt((-7)^2 + (3 + 1)^2)

Multiply each exponent in -7 by 2:

For each pen, the dimensions are given as follows:

For the entire pen, the dimensions are given as follows:

You have 200 meters of fencing to enclose two adjacent rectangular pens for livestock, hence the perimeter is given as follows:

2(2x + y) = 200

2x + y = 100.

The total area of the enclosed region is 1400 square meters, hence:

2xy = 1400.

From the first equation, we have that:

y = 100 - 2x.

Replacing in the second, the length x is obtained as follows:

2x(100 - 2x) = 1400

-4x² + 200x - 1400 = 0

Ling can therefore purchase 0 to 12 bags, but no more is the right decision.

Ling has been instructed to spend no more than $40.00 on party décor. She has already spent $10.00 on streamers but also plans to purchase bags of balloons. The price of a bag of balloons is $2.50.

Given her spending cap and how much she has already spent on streamers, the inequality  10 + 2.5x ≤ 40 indicates x, the number of bags she can purchase.

Subtracting 10 from both sides of our inequality, let's find x by reversing the inequality.

10 - 10 + 2.5 x ≤ 40 - 10

2.5 x ≤ 30.

We will now divide our inequality by 2.5 on both sides.

The relation is:

Is a function, because each element in the domain is mapped to a single element in the range.

A relation maps elements from one set, called the domain, into another set, called the range.

For example, the element x mapped into element y is written as (x, y).

Particularly, a relation is a function if each element from the domain is mapped into only one element of the range.

So, if we had two points like (2, 4) and (2, 5), then the relation is not a function (because the element 2 is mapped into two different elements of the range).

Here the relation is:

Assume that after 'n' years the amount will be doubled i.e $ 1800

From the given problem,

Amount, A = 900(1+0.06/12)¹²ⁿ        

= 900(1+0.06/12)¹²ⁿ

= 900(1 + 0.005)¹²ⁿ

As we assumed after 'n' years the amount is $ 1800

=> 900 (1.005)¹²ⁿ = 1800  

=> (1.005)¹²ⁿ = 2    

Apply to log on both sides

Step-by-step explanation:

Because it says -8 x 7, the * is negative and the 7 is positive.

Answer: To determine Alejandro's earnings for the first 4 weeks, we first need to calculate his weekly pay. To do this, we divide his annual salary by the number of weeks in a year:

Annual salary / 52 weeks/year = weekly pay

$71,500 / 52 weeks/year = $1,375/week

Next, we need to determine the agency fee that Alejandro will pay each week. The agency fee is equal to 40% of the first 5 weeks' pay, so we multiply Alejandro's weekly pay by 40% to get the agency fee:

Weekly pay * 40% = agency fee

$1,375/week * 40% = $550/week

Finally, to determine Alejandro's earnings for the first 4 weeks, we multiply his weekly earnings by the number of weeks:

Weekly pay * number of weeks = earnings

$1,375/week * 4 weeks = $5,500

So, Alejandro will earn $5,500 during the first 4 weeks of his new job, after paying the agency fee each week.
