Step-by-step explanation:

becuase that is the answer

The difference between the sum of the first 50 counting numbers and the sum of the first 100 counting numbers is 3775.

Here we have to find the difference between the first 50 counting numbers and first 100 counting numbers.

Formula to find the sum of the number n is:

[tex]S_{n}[/tex] = n/2( 2a + (n-1)d)

a = first number of the series

d = common difference

n = number of series

Sum of first 50 counting numbers:

[tex]S_{50}[/tex] = 50/2( 2× 1 + (50-1) 1)

    = 25 × 51

    = 1275

Sum of first 100 counting numbers:

[tex]S_{100}[/tex] = 100/2 ( 2×1 + (100- 1) 1)

      = 50 × 101

      = 5050

Now the difference between them:

[tex]S_{100}[/tex] - [tex]S_{50}[/tex] = 5050 - 1275

              = 3775

Therefore the difference is 3775.

The equation of the line in Slope-Intercept Form is y = 1/3x - 6

Given,

A line passes through the points (−6,−8) and (−3,−7).

To find the equation of the line in Slope-Intercept Form

Now, According to the question:

Write the slope formula :

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Substitute x1 = -6 , x2 = -3 and y1 = -8 , y2 = -7 into above slope formula:

Calculate;

[tex]m = \frac{-7-(-8)}{-3-(-6)}[/tex]

Determine the sign :

m = (-7+8)/ (-3+6)

m = 1/3

Substitute m = 1/3 , x = -6 and y = -8 into y = mx + b

Calculate:

-8 = 1/3 x (-6) + b

Reduce the expression:

-8 = -2 + b

-b = 6

b = -6

Again , Substitute

y = 1/3x - 6

m = 1/3  into y = mx +b:

y = 1/3x - 6

Slope-intercept form -> y = mx + c

Putting B(0,-5) in slope-intercept form,

-5 = m(0) + c

 c = -5

Putting A(6,0) in slope-intercept form,

  0 = m(6) - 5

6m = 5

 m = 5/6

A parabola can be drawn given a focus of (−3,−3) and a directrix of x=5.

Now, let's take (x,y) to be the points of parabola.

So, we have the following expression:

Distance between (-3,-3) and (x,y) = Distance between (x,y) and x = 5

Distance between (x,y) and x = 5 will be Ix-5I

Now, we will use distance formula to solve this expression further.

If r persons need to be selected from total n members and the order does not matter, the number of ways it can be selected is calculated using the combination formula:

  ⁿCr = n! / [(n-r)! r!]

Data from the problem:

Total man = 10

Man to be chosen = 3

Total woman = 15

Woman to be chosen = 3

Hence,

The number of ways men can be selected =   ¹⁰C₃ = 10! /(3! 7!)

                                                                       = 120

The number of ways women can be selected =   ¹⁵C₃ = 15! /(3! 12!)

                                                                       = 455

The number of ways men and women selected:

a. solve for the number of students in 2001.

okay, so there is already the equation given, so we just have to put the right number in the x.

it says x represents the number of years after 1998;

then it means we should add the number we added in years to zero for x

(if I didn't get it wrong).

so if x is 1 in 1999, in 2001 it is 3.

let's put 3 in the equation: y=123.1(1.069)^3 -> y=123.1*1.2 -> y=147.7

answer for a: the number of students in 2001 is 147.7 in thousands.

b. solve for the number of students in 2018.

add the number you added in years to zero in order to solve x.

1998+20=2018,
