Given P(A) = 0.44, P(B) 0.6 and P(An B) = 0.394, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.

Answers

Given:

[tex]P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394[/tex].

To find:

The value of [tex]P(A\cup B)[/tex], rounding to the nearest thousandth.

Solution:

We know that,

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

On substituting [tex]P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394[/tex], we get

[tex]P(A\cup B)=0.44+0.6-0.394[/tex]

[tex]P(A\cup B)=0.646[/tex]

Therefore, the value of [tex]P(A\cup B)[/tex] is 0.646.

1. Determine the lateral and total surface
area of the pyramid.


(I need full explanation on how to solve

Answers

Answer:

Laterial surface area: 73 cm²Total surface area: 93 cm²

Step-by-step explanation:

The laterial surface area is the sum of the areas of the triangles. There are two triangles with dimensions: base = 4 cm, height = 8cm and two triangles with dimensions: base = 5cm, height = 8.2cm.

The laterial surface area LSA is:

LSA = 2 • ( 4.8/2) + 2 • ( 5 • 8.2/2)

LSA = 4 • 8 + 5 • 8.2

LSA = 73 cm²

The total surface area SA is the LSA plus the area of the base of the pyramid, which is a rectangle with dimensions: 4cm x 5cm:

SA = LSA + 4 5

SA = 73 cm + 20 cm²

SA = 93 cm²

the question is find the product of -8 and the sum of -2(10x + 3y) and -5(6y -7x)

Answers

Answer:

Step-by-step explanation:

-2(10x + 3y)

-20x -6y         [-2 multiplied by 10x = 20x,      negative + positive = negative]

-5(6y -7x)

-30y + 35x

-20x -6y -30y +35x

35x - 20x     -30y -6y

          15x - 36y

Answer = 15x -36y

Answer:

- 120x + 288y

Step-by-step explanation:

Begin by summing the 2 expressions

- 2(10x + 3y) - 5(6y - 7x) ← distribute parenthesis

= - 20x - 6y - 30y + 35x ← collect like terms

= 15x - 36y

Now multiply the result by - 8

- 8(15x - 36y) ← distribute

= - 120x + 288y

Answer:

Let the marked price =Rs100

After a discount of 20%, the price = 100−20% of100 = 100−10020×100 = 100−20=80

After a further discount of 5%, price = 80−5% of80 = 80−1005×80 = 80−4 = Rs76

Final Selling = Rs76

Total Discount = 100−76=Rs24

Answers

Step-by-step explanation: Go.dzilla 2 king of monsters is one of the best movies out there in my opinion, right down to the CGI, the movie makers did a fantastic job of creating an emotional attachment to the family in the movie.  

Basically in the movie it starts in a nuclear power plant, the power plant has a melt down, kil.ling the team that went into the core to see what the issue was, the director of the power plants wife died and he knew that it wasn.t normal for the plant to meltdown the way it did, so he dedicates the rest of his life to trying to figure out what really happened there. He even goes as far as to sneak in to the restricted area with his son, when there they find out that they are digging up something from the wreckage, this is the giant moth (it wont let me say the name), The giant moth was feeding on the nuclear radiation and that was what caused the plant to melt down all those years ago. the giant moth then flies across the country searching for nuclear radiation and in turn waking her mate and destroying the place, this awakens Go.dzilla so that he can reassert himself as the ap.ex predator. He finds both the giant moths and kil.ls them and then returns to the bottom of the ocean.

what two number multiply to 24 and add to -11

Answers

Answer:

8 and 3

Step-by-step explanation:

Brainliest Please

Answer:

One example is x = -8, y = -3

Step-by-step explanation:

Lets make a system of equations.

Let x be the first number and y be the second.

x * y = 24

x + y = -11

Solve for x and substitute.

x = 24/y

24/y + y = -11

24 + y^2 = -11y

y^2 + 11y + 24 = 0

Factor.

(y + 8)(y+3) = 0

So one example is x = -8, y = -3

A company rents out 17 food booths and 24 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The fee for a game booth is $80 plus $9 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.

Answers

Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d

The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d
