True or false is Every integer a positive number

STatiana [176]

integers are numbers that we get from adding and subtracting the number 1. Zero also belongs to integers .

example

3 = 1+ 1 + 1
3 = 1 + 1 + 1 +1 - 1
0 = 1 + 1 - 1 - 1
- 4 = -1 - 1 - 1 -1
- 4 = 1 - 1 -1 - 1 - 1

In this way you can get infinitely large number of total positive , negative and zero

kolbaska11 [484]

Answer: 400 adult tickets were sold.

Step-by-step explanation:

Let x represent the adult tickets that were sold.

Let y represent the number of children tickets that were sold.

1000 tickets were sold to the seaport aquariums dolphin show. This means that

x + y = 1000

Adult tickets cost $10. Children tickets cost two dollars and a total of 5200 was collected. This means that

10x + 2y = 5200 - - - - - - - -1

Substituting x = 1000 - y into equation 1, it becomes

10(1000 - y) + 2y = 5200

10000 - 10y + 2y = 5200

- 10y + 2y = 5200 - 10000

- 8y = - 4800

y = - 4800/ - 8

y = 600

x = 1000 - y = 1000 - 600

x = 400

A department store sells sport shirts in three sizes (small, medium, and large), three patterns (plaid, print, and stripe), and

butalik [34]

Answer and Step-by-step explanation:

a) probability of selling a medium, long sleeved printed shirt, P(M ∩LS ∩PR) = 0.07, directly from the table of probabilities

b) probability that the next shirt sold is a medium printed shirt, (M ∩Pr) = P(M,Pr,LS) + P(M,Pr,SS) = 0.07+0.10 = 0.17

c) probability that the next shirt is a short sleeved shirt, P(SS) = sum of 9 probabilities in Short Sleeved shirt table = 0.58

probability that the next shirt is a long sleeved shirt, P(LS) = 1 - 0.58 = 0.42 or add up the total probabilities in the long sleeved shirt table, P(LS) = sum of 9 probabilities in the long sleeved shirt table = 0.42

d) probability that the next shirt is a medium, P(M) = P(M,SS) + P(M,LS) = (0.07+0.10+0.12) + (0.06+0.07+0.07) = 0.49

probability that the next shirt sold is a print, P(Pr) = P(Pr,SS) + P(Pr,LS) = (0.02+0.10+0.07) + (0.02+0.07+0.02) = 0.40

e) probability that the shirt sold is a medium given that the shirt just sold was a short-sleeved plaid, P(M|SS,PL) = (P(M,SS,PL))/P(SS,PL) = 0.07/(0.04+0.07+0.03) = 0.5

f) probability that the shirt sold is short sleeved given that the shirt just sold was a medium plaid, P(SS|M,PL) = (P(M,SS,PL))/P(M,PL) = 0.07/(0.07+0.06) = 0.53846 = 0.54

probability that the shirt sold is long sleeved given that the shirt just sold was a medium plaid, P(LS|M,PL) = (P(M,LS,PL))/P(M,PL) = 0.06/(0.07+0.06) = 0.462 = 0.46
