Number of ways can this company buy them is 1623160.

Given :

a store is selling laptops with six different operating systems. a company would like to buy 35 of those laptops for their employees.

Number of ways = [tex]35_C_6[/tex] or C ( 35 , 6 )

we know that ,

C ( n , r ) = n! / ( n - r ) ! r!

substitute

= 35 ! / ( 35 - 6 ) ! 6!

= 35 * 34 * 33 * 32 * 31 * 30 * 29! / 29! * 6!

= 35 * 34 * 33 * 32 * 31 * 5 / 5 * 4 * 3 * 2 * 1

The day worker's daily compensation is $160, while the concrete finisher's daily wage is $143.

A matrix is a numerical arrangement that is divided into rows and columns. Introduce yourself to matrices and learn about their dimensions and elements. A matrix is a rectangular array of integers divided into rows and columns. Matrix A, for example, contains two rows and three columns. A matrix is a collection of integers that are organized in rows and columns to form a rectangular array. The numbers are referred to as matrix elements or entries. Matrices are widely used in engineering, physics, economics, and statistics, as well as in many disciplines of mathematics.

Here,

Let x be the Charge for day labor and y be the charge for concrete finisher,

8x+2y=1464

x+5y=943

multiply x+5y=943 by 8,

8x+40y=7544

8x+2y=1464

subtracting them,

38y=6080

y=$160

x+5*160=943

x=943-800

x=$143

To find the point and slope given by the equation y + 2 = -7(x-1), we can start by rearranging the equation to solve for y:

y + 2 = -7(x-1)

y = -7(x-1) - 2

y = -7x + 7 + (-2)

y = -7x - 9

This is the slope-intercept form of the equation, where y = -7x - 9 is the slope and (-9, 0) is the y-intercept.

The slope of the line is -7, and the point on the line is (-9, 0).

Therefore, the point and slope given by the equation y + 2 = -7(x-1) are (-9, 0) and -7, respectively.

The value of the notation Δy from the points (-3,-5) and (0,10) is 15

The complete question is added at the end of this solution

From the question, we have the following parameters that can be used in our computation:

Points = (-3,-5) and (0,10)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) = (-3,-5) and (0,10)

The notation Δy represents the change in the y values of the given points

This notation can be extended to calculate the slope of the points

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (-3,-5) and (0,10)

Substitute the known values in the above equation

So, we have the following equation

Slope = (10 + 5)/(0 + 3)

Evaluate the sum

Slope = 15/3

The numerator represents Δy

i.e. Δy= 15

Evaluate the quotients

Slope = 5

Hence, the slope of the line is 5 and the value of the notation Δy is 15

The solution for the expression 2^(x) − 2^(−x) = 5 is x = log2(10)

Substitute 2^(−x) for 5 and solve for x, which is log2(10).

The given expression ,

2^(x) − 2^(−x) = 5

2^(x) = 5 + 2^(−x)

2^(2x) = (5 + 2^(−x))^2

2^(2x) = 25 + 10*2^(−x) + 2^(−2x)

25 + 10*2^(−x) + 2^(−2x) = 2^(2x)

25 − 2^(2x) = 10*2^(−x) − 2^(−2x)

25 − 2^(2x) = 10*2^(−x) − 2^(−2x) + 2^(2x)

25 = 10*2^(−x) + 2^(2x) − 2^(−2x)

25 = 10*2^(−x) + 2^(−2x) (2^(2x) - 2^(−2x))

25/(2^(−2x) (2^(2x) − 2^(−2x))) = 10*2^(−x)

25/(2^(2x) − 2^(−2x)) = 10*2^(−x)

To solve this problem, we can use the standard normal distribution and the Z-score formula to find the probability that a pregnancy will last at least 300 days.

The Z-score is a measure of how many standard deviations a value is from the mean. We can use the Z-score to standardize a value, which means we can express it in terms of how many standard deviations it is from the mean of the distribution.

The Z-score formula is:

Z = (x - μ) / σ

Where x is the value we are standardizing, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

To find the probability that a pregnancy will last at least 300 days, we can use the Z-score formula to standardize 300 days:

Z = (300 - 268) / 15 = 4

This means that 300 days is 4 standard deviations above the mean of 268 days.

To find the probability that a pregnancy will last at least 300 days, we can use a Z-table or a calculator to find the area under the standard normal curve that is greater than or equal to 4 standard deviations.

Using a calculator or a Z-table, we find that the probability that a pregnancy will last at least 300 days is approximately 0.0165, which corresponds to answer choice D: 0.0165.

To find the length of BE, we can use the Pythagorean theorem to find the length of AC, and then use the fact that DE is parallel to AC to find the length of BE.

First, we use the Pythagorean theorem to find AC:

AC^2 = AD^2 + DC^2

Substituting the known values, we get:

AC^2 = 18^2 + 12^2

AC^2 = 324

AC = sqrt(324) = 18

Since DE is parallel to AC, we can set up a proportion to find the length of BE:

BE/EC = AC/DC

Substituting the known values, we get:

BE/12 = 18/12

BE = (18/12) * 12

BE = 18/1

BE = 18

Therefore, the length of BE is 18.
