Answer:

P(-A) = 0.388

Step-by-step explanation:

By the <u> PROBABILITY POSTULATE: </u>

P(A) + P(not A) = 1

Here, P(A) = 0.612

So, P(not A) = P(-A) = 1 - 0.612 = 0.388

⇒P(-A) = 0.388

Answer:

There is no unique solution to this problem.

There are infinitely many solutions to this problem.

Step-by-step explanation:

Let B denotes broccoli crop

Let S denotes spinach crop

Last year, he grew 6 tons of broccoli per acre and 9 tons of spinach per acre, for a total of 93 tons of vegetables.

Mathematically,

6B + 9S = 93 eq. 1

This year, he grew 2 tons of broccoli per acre and 3 tons of spinach per acre, for a total of 31 tons of vegetables.

Mathematically,

2B + 3S = 31

2B = 31 - 3S

B = (31 - 3S)/2 eq. 2

Substitute eq. 2 into eq. 1

6B + 9S = 93

6[(31 - 3S)/2] + 9S = 93

3(31 - 3S) + 9S = 93

93 - 9S + 9S = 93

- 9S + 9S = 93 - 93

0 = 0

Therefore, there is no unique solution to this problem.

Which means that there are infinitely many solutions to this problem.

Answer:

x = -4 y = -5

Step-by-step explanation:

2x + 3 = -x - 9

3x + 3 = -9

3x = -12

x = -4

y = - (-4) - 9

y = 4 - 9

y = -5

The table below shows the numbers of tickets sold at a movie theater on Friday.

sleet_krkn [62]

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday

= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold = 2 times as many as the number of adult tickets sold

on Friday

= 1,678 x 2 = 3,356

Children's Tickets sold = 3 times as many as the number of children's

tickets sold on Friday.

= 976 x 3 = 2, 928

So, the total number of tickets sold on Saturday

= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 + 6, 284 = 8,938

Hence, total number of tickets sold over these two days is 8,938.
