The probability of events A
and B is

P(A)=1/2

P(B)=1/3

P(A∩B)=1/4.

What is the value of P(A or B)?
Enter your answer as a fraction, like this: 4/25

Answers

Answer 1

Answer: 2/3

Step-by-step explanation:

To find the probability of A or B, we can use the formula: P(A or B) = P(A) + P(B) - P(A ∩ B)

Plugging in the given values:

P(A or B) = 1/2 + 1/3 - 1/4

To solve this, we must find a common denominator in order to add the fractions:

P(A or B) = 3/6 + 2/6 - 1/6

Simplifying:

P(A or B) = 4/6 = 2/3

So the value of P(A or B) is 2/3

write the trinomial as a square of a binomial or as an expression opposite to a square of a binomial
24ab-16a^2-9b^2

Answers

-(4a-3b)^2 is the answer

Answer: The given trinomial, 24ab-16a^2-9b^2, can be written as an expression opposite to a square of a binomial.

To do this, we first factor out the greatest common factor of -4a, which gives us:

-4a(6b-4a-9b^2)

We can then factor -9b^2 as -(3b)^2, and group the remaining terms together:

-4a((3b-2a)^2-4a^2)

So the trinomial can be written as -4a( (3b-2a)^2 - 4a^2 ) which is an expression opposite to a square of a binomial (3b-2a)^2.

ABCD is a cyclic quadilateral in whicj side Ad and BC are produced to meet at E such that AE = BE .Prove that AB// DC

Answers

Answer: To prove that AB is parallel to DC, we can use the following steps:

Draw a diagram of the cyclic quadrilateral ABCD with the point E where sides AD and BC are produced to meet.

Since ABCD is a cyclic quadrilateral, all its interior angles add up to 360 degrees. Therefore, angle A + angle B + angle C + angle D = 360 degrees.

Since AE = BE, we can say that angles A and B are equal (by corresponding angles). Similarly, angles C and D are also equal.

Since angles A and B are equal and angles C and D are also equal, we can say that angle A + angle B = angle C + angle D.

Substituting this into our equation from step 2, we get: angle A + angle B + angle C + angle D = angle A + angle B + angle A + angle B.

Simplifying, we get: 360 = 2(angle A + angle B). This means that angle A + angle B = 180.

Since angle A + angle B = 180, we can say that angle A = angle B and angle C = angle D.

Now we can use the fact that corresponding angles are equal, then angle A = angle C and angle B = angle D.

We know that opposite angles of a parallelogram are equal, so we have proved that AB is parallel to DC.

It's important to note that this proof uses the fact that quadrilateral ABCD is cyclic, which means that the sum of its angles is equal to 360 degrees. It also uses the fact that opposite angles are equal in a parallelogram, and corresponding angles are equal when two lines are parallel.

The area of the quare felid i 40,000 quared and we want to but a fence diagonally through the field. What hould the length of the fence be?

Answers

The length of the fence must be 282.84 ft.

Area of the field =  40,000 ft²,

The length of the fence will be equal to the diagonal of the square.

For a square of side length S, the area is:

A = S²

Substituting the values in the formula -

S² = 40,000 ft

Applying the square root on both sides -

S = √(40,000 ft²)

Calculating, the diagonal of a square of side length S is:

D = S x√2,

Substituting the values -

D = √(40,000 ft²) x √2

Answers

The annual interest rate on the loan is 0.02 or 2%.

What is the annual interest rate?

To find the annual interest rate on the loan, we need to use the formula for simple interest:

I = Prt

where:

I is the interest,

P is the principal (the amount of the loan),

r is the annual interest rate (expressed as a decimal),

t is the time in years

We know the following information:

I = $240

P = $4000

t = 3

We can use this information to set up the equation and solve for r:

240 = 4000 * r * 3

240 = 12000r

r = 240/12000

r = 0.02

Therefore, the annual interest rate on the loan is 0.02 or 2%.
