If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.

Probability is that branch of mathematics that deals with the numerical description of the possibility of an event to occur. The probability of any event is a number between 0 and 1 where 0 represents the impossibility of the event to occur while 1 represents certainty of that event to occur.

As the probability of the job a and job b are independent of each other, the probability that both jobs will be offered can be determined by using the formula;

P(A∩B) = P(A) × P(B)

Here, P(A∩B) represents the probability of both the events happening together

As P(A) = 0.25

P(B) = 0.20

P(A∩B) = 0.25 × 0.20

P(A∩B) = 0.05

Hence, the probability that both jobs will be offered is calculated to be 0.05.

It will take the painter more than 40 hours to paint all 20 rooms in stately wayne manor .

Time taken for the first 3 rooms =9hrs

Learning curve rate = 85%

Time taken for the next 20 rooms =?

Time taken for 1 room = 9hrs / 3 rooms = 3 hrs

If it takes 3 hrs to paint 1 room

Therefore, it will take x hrs to paint 20 rooms would take;

Hence, 20 rooms multiplied 3 hrs = 60 hours

It may take 60 hours to complete painting the 20 rooms.

At a learning curve rate of 85%, 15% will be the progress rate

Therefore, it will take additional 15% of 60 hours to paint the 20 room.

Try the code AEAA. Let me know if its right or not.

Answer:

CHGD

Step-by-step explanation:

You should actually solve each of these puzzles to get the right code
1. To evaluate f(-2)

We have f(x) = x³ - 2x

Substitute -2 for x

==> (-2)³ - (2 x-2)
-2³ = -8
2 x -2 = -4

==> f(-2) = -8 - (-4)
==> f(-2) = -8 + 4      (two negatives make a positive
==> f(-2) = -4            Letter C

2. Evaluate g(-10)
[tex]g(x) = \dfrac{3x}{2}[/tex]

[tex]g(-10) = \dfrac{3 \times -10}{2} \\= \dfrac{-30}{2} \\\\= \boldsymbol{-15}[/tex]        Letter H

3. Evaluate h(-1)
h(x) = 2x² + x
h(1) = 2 x (-1)² - 1

= 2 x 1 - 1

= 1            Letter G

4. Evaluate f(3)
f(x) = x³ -2x
f(3) = 3³ - 2 x 3

= 27 - 6

= 21              Letter D

So the correct code is CHGD

What is a rational number ?

If p & q are any two numbers where q is not equal to 0, then the fraction in form p/q is called as rational number.

A number is given which is √22.

√22 = 4.69041576

Let's check which of the statements are correct.

A.

√22 is not rational number as the number has non - terminating decimal value which is 4.69041576 and it doesn't lies between 10 and 12. So , this option is not correct.

B.

This option is also not correct as the value of √22 nearly equals 4.69 is and not greater than 4.691.

C.

The value of √22 is 4.69041576.

If we round off to the nearest hundredth , 9 is at the hundredth place , so the value will be 4.69. This is a correct option.

D.

√22 is not a rational number as the number has non - terminating decimal value which is 4.69041576 but it lies between 4 and 5. So , this option is not correct.

E.

The value of √22 is 4.69041576. We can observe that the decimal number doesn't repeat. So , this is a correct option.

F.

As we know √22 is not a rational number we can't represent it as fraction. This option is not correct.

Therefore , the correct statements among given statements are statement C and E.

The commutative property for addition just means the sum is the same no matter what order you add the terms. This property is also true for multiplication of real numbers.

If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics. Numerous binary operations depend on it as a fundamental property, and numerous mathematical arguments.

A commutative property in mathematics states that if integer positions are switched around or combined while performing addition or multiplication operations, the result will remain the same.

According to the commutative property, the numbers we use can be moved around or swapped around without changing the solution. For addition and multiplication, the property is true, but not for division or subtraction.

Step-by-step explanation:

The equation is given by A = n³ - 8 , where n is a number

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number be represented as n

A = 8 is subtracted from the cube of a number

Substituting the values in the equation , we get

A = n³ - 8   be equation (1)

c. The slope of the altitude of the triangle that passes through point R doesn't exists.

What is slope of a line segment ?

Slope is the ratio of the difference in y-coordinates over the equivalent x-coordinates between two different locations on a line.

It is given that the vertices of a triangle are P(-6,1), Q(-2,-5) and R(8,1).

a.

The midpoint (M) of QR will be equal to

( [tex]\frac{-2 + 8}{2} , \frac{-5 + 1}{2}[/tex] )

or

M = (-3 , 2)

Now , slope of line QR will be ;

[tex]m_{QR}[/tex] = [tex]\frac{1+5}{8+2}[/tex]

[tex]m_{QR}[/tex] = 6 / 10

We know that :

m × [tex]m_{QR}[/tex] = -1

m = -10 / 6

or

m = -5 / 3

Equation of line will be given as :

y + 2 = [tex]\frac{-5}{3}[/tex] ( x - 3 )

y = [tex]\frac{-5}{3}[/tex] x + 3

b.

The midpoint of PQ will be :

= ([tex]\frac{-6 - 2}{2} , \frac{1 - 5}{2}[/tex])

= ( -4 , -2)

The slope of median of triangle that passes through point R will be ;

m = [tex]\frac{-2 - 1}{-4-8}[/tex]

m = -3 / -12

m = 1/4

or

m = 0.25

c.

Slope of altitude of triangle that passes through point Q will be :

m = [tex]\frac{1 - 1}{-6-8}[/tex]

m = 0 / -14

m = 0

The slope in this case doesn't exist.

Therefore the answers will be :

a. The equation of perpendicular bisector of QR is y = [tex]\frac{-5}{3}[/tex] x + 3.

b. The slope of median of triangle passing through point R is 1/4.

c. The slope of the altitude of the triangle that passes through point R doesn't exists.
