a. 24. The Venn Diagram below shows the badges: camping, swimming, and first aid. number of boy scouts in a certain troop who have earned the following merit Camping Swimming 10 4 7 2 6 3 5 2 First Aid

The answer is below

Step-by-step explanation:

Let C represent the boy scout with camping badge, S for boy scout with swimming badge and F for boy scout with first aid badge.

a) The number of boy scout with first aid badge = boy scout with all three badges + boy scout with first aid badges alone + boy scout with first aid and swimming badges + boy scout with first aid and camping badges

The number of boy scout with first aid badge = 2 + 5 + 6 + 3  = 16

b) The number of boy scout with camping badge or swimming badge = C ∪ S = 10 + 4 + 2 + 6 + 7 + 3 = 32

c) The number of boy scout with camping badge and first badge = C ∩ F = 6 + 2 = 8

d) The number of boy scout with swimming badge but do not have first aid badge = S ∪ F' = 4 + 7 = 11

e) The number of boy scout without camping badge = C' = 7 + 3 + 5 = 15

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.

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
