<h2>
Length of track is 168 meter</h2>
Step-by-step explanation:
Let l be the length of track.
Running speed = 4 m/s
Jogging speed = 2 m/s
Total time taken = 2 minutes 6 seconds. = 126 seconds
That is
Length of track is 168 meter

Answer:
a. 7/22
b. 28/33
c. 7/22
d. dependent events
Step-by-step explanation:
The total number of cards is given as 7 + 5 = 12.
The probability if a card being green on the first pick, P(G) = 7/12
The probability of a card being yellow on the first pick, P(Y) = 5/12
Because there is no replacement, the card are going to be short by one card. Therefore, the second pick will be like this:
P(GG) = ( 7/12×6/11)
P(GY) = ( 7/12 × 5/11)
P(YG) = ( 5/12×7/11)
P(RR) = ( 5/12 ×4/11)
a. P (G1 and G2) = ( 7/12×6/11)
= 7/22
b. P( At least one is green) = ( 7/12×6/11) + ( 7/12 × 5/11) + ( 5/12×7/11)
= 28/33
c. P(G2G1) = 7/22
d. the events are dependent. They do not give the same result.
2a+3c=22.00 ......equation 1
a+4c=18.50 =>2a+8c=37.00 .....equation 2
subtract equation one from equation two:
5c=37-22=15
c=3
a+4*3=18.50 =>a=6.50
for the Hu family: 3*6.50+1*3.00=22.50 dollars
