Look at the attendance figures shown in the table below. Volley Ball Rugby 7s Junior Athletics attendance figure < 12s 700 500 2,400 12s ≤ attendance figure < 21s 1,000 1,000 2,250 21s ≤ attendance figure < 65s 3,050 2,500 3,350 attendance figure ≥ 65s 250 1,000 2,000 A seat is selected at random for the Fan Camera, which shows crowd reactions during the event. What is the probability that the Fan Camera will show someone the age of 12 or older, but less than 21, during the Volley Ball game? Give your answer as a decimal. What is the probability that the Fan Camera will not select someone less than 12 years of age during a Rugby 7s match? Give your answer as a percentage. % Select which of the probabilities below represent the likelihood of the Fan Camera selecting someone 65 and over at the Junior Athletics event.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
