You can model an arch at your school using the equation. y = -3/4(x + 4) (x – 4), where "x" and "y" are measured in feet. The x-

axis represents ground.
Find the width of an arch at ground level.

Yulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.

Pie

Answer:

the answer is 1/6

Step-by-step explanation:

Let (a,b) denote a possible outcome of rolling the two die, with a the number on the top of the first die and b the number on the top of the second die. Note that each of a and b can be any of the integers from 1 through 6. Here is a listing of all the joint possibilities for (a,b):

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

With the above declaration, the outcomes where the sum of the two dice is equal to 7 form an event. If we call this event E, we have

E={(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)}.

so Possibilities(P) of having Event (E)

P(E)=6/36

= 1/6

Point G is in love segment FH give an FH equals 4XGH equals XNFG Eagles 2X +10 determine the numerical link of FG

victus00 [196]

Answer:

FG= 30

Step-by-step explanation:

Point G is on line Segment FH

Given

FH= 4x

GH= x

FG= 2x+10

If the point G is on the line FH then the total of the two line segement FG and GH must be equal to FH

FH= FG+ GH

Putting the values in the above equation:

4x= 2x+10+x

4x= 3x+10 Solving for x

10= 4x-3x

10= x

FG= 2x +10

FG = 2(10) +10 Putting the value of x

FG= 20+10

FG= 30

Check :

FH= 4x= 4(10)= 40

GH= x= 10

FG = FH- GH= 40-10= 30

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!<br><br> Solve for n.

grigory [225]

If you expand the left hand side, the inequality becomes

$3n+18 \geq 3n+8$

As you can see, $3n$ appears on both sides, which means that it cancels out. You can subtract $3n$ from both sides to get

$18 \geq 8$

and this is clearly always true. If you interpreted the inequality with words, it would sound like

"For which values of n is 18 greater than 8"

Since the inequality does not depend on n anymore and the remaining part is true (18 is indeed greater than 8), every possible value of n satisfies the inequality.
