The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented b

Tamiku [17]

Answer:

A; the actual length of the land bridge from P to H is 50 yards

Step-by-step explanation:

Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.

Mathematically, to calculate this distance, we make use of the distance formula;

D = √(x2-x1)^2 + (y2-y1)^2

In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)

Substituting these values

D = √(32-2)^2 + (15-55)^2

D = √(-30)^2 + (-40)^2

D = √(900 + 1600)

D = √(2,500)

D = 50 units

Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards

Tasya [4]

Answer:

Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee. = 360

Step-by-step explanation:

Given -

A business organization needs to make up a 8 member fund-raising committee.

The organization has 6 accounting majors and 6 finance majors .

Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee.

(1) chose 4 accounting majors from 6 and chose 4 finance majors from 6 =

= $\binom{6}{4}\times\binom{6}{4}$

= $\frac{(6!)}{(2!)(4!)}\times \frac{(6!)}{(2!)(4!)}$ = 225

(2) chose 5 accounting majors from 6 and chose 3 finance majors from 6 = $\binom{6}{5}\times\binom{6}{3}$

= $\frac{(6!)}{(1!)(5!)}\times\frac{(6!)}{(3!)(3!)}$ = 120

(3) chose 6 accounting majors from 6 and chose 2 finance majors from 6 = $\binom{6}{6}\times \binom{6}{2}$

= $\frac{(6!)}{(6!)(0!)}\times\frac{(6!)}{(2!)(4!)}$ = 15

Then total no of ways = (1) + (2) + 3

= 360
