Answer:
Na = 720 - 120 = 600 ways
The 3 people can arrange themselves in 600 possible ways.
Step-by-step explanation:
For at least one of the three friends to seat on an aisle seat, the number of possible arrangements can be given as;
Na = Nt - Nn .....1
Where;
Na = number of possible arrangements with at least one of the seating on an aisle seat.
Nt = total number of possible arrangements for the three friends
Nn = number of possible arrangements with none of the three friends seating on an aisle seat.
Given;
Total number of seats available = 10
Total number of aisle seats available = 4
Total number of people = 3
So;
Nt = 10C3 = 10×9×8 = 720
Nn = (10-4)C3 = 6C3 = 6×5×4 = 120
From equation 1;
Na = 720 - 120 = 600 ways
The 3 people can arrange themselves in 600 possible ways.
Answer:
69420
Step-by-step explanation:
you need to include the graph in your question.
you just posted the question with no graph
1 mile=5280 feet
90 miles= 475200
1 hour=3600 seconds
475200÷3600=132, so this rate is 132 feet per second, and the ball would travel 66 feet in half a second(but I am not sure the second answer is right or not). Hope it help!

<em><u>show the total cost for the first 4 months of this cellphone plan
:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
<em><u>Solution:</u></em>
Given that,
The equation is:
C = 45m + 25
Where,
C is the total cost in dollars
m is number of months
<em><u>show the total cost for the first 4 months of this cellphone plan
</u></em>
<em><u>First month</u></em>
m = 1
C = 45(1) + 25
C = 45 + 25
C = 70
<em><u>Second month</u></em>
m = 2
C = 45(2) + 25
C = 90 + 25
C = 115
<em><u>Third month</u></em>
m = 3
C = 45(3) + 25
C = 160
<em><u>Fourth month</u></em>
m = 4
C = 45(4) + 25
C = 205
<em><u>Thus the table is:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
Thus the table is formed
