Answer:

[tex]\frac{17}{27}[/tex]

Step-by-step explanation:

Given: Events A and B are such that [tex]P(A)=38\,,\,P(B)=27[/tex] and P(A∩B) = 17

To find: [tex]P(A|B)[/tex]

Solution:

Probability refers to the chances of occurrence of any event.

An event is described as an outcome of a random experiment.

A random experiment is an experiment for which outcomes cannot be predicted.

[tex]P(A|B)=[/tex] P(A∩B) ÷ P(B) = [tex]\frac{17}{27}[/tex]

Answer:

a) 3x+4

b) 6×3+4

Step-by-step explanation:

Answer: a) [tex]x=\dfrac{-9 \pm\sqrt{113} }{8}[/tex]

              b) x₁ = - 14; x₂ = 6.

Step-by-step explanation:

a) 4x² + 9x - 2 = 0

[tex]x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=4; \: \: b=9; \: \: c=-2\\x =\dfrac{-9 \pm \sqrt{9^{2}-4 \cdot 4 \cdot (-2) } }{2 \cdot 4} =\dfrac{-9 \pm\sqrt{113} }{8}[/tex]

b) x² + 8x - 84 = 0

[tex]x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=1; \: \: b=8; \: \: c=-84\\\\x =\dfrac{-8 \pm \sqrt{8^{2}-4 \cdot 1 \cdot (-84) } }{2 \cdot 1} =\dfrac{-8 \pm\sqrt{400} }{2}=\dfrac{-8 \pm 20}{2} =-4 \pm 10\\\\x_{1} =-14\\x_{2} =6[/tex]

Answer:

77.00

Step-by-step explanation:

14 is the answer

Step-by-step explanation:

0+14=14

The final cost of the stereo system after the discount and including the tax is $337.88. The correct option is D.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the regular price of a stereo system at Best Buy is $375. The system is on sale for 15% off the regular price. The sales tax rate is 6%.

The discounted price is calculated as,

Discounted Price = 375 x 0.85

Discounted Price = 318.75

The total price after sales tax is,

Total price = 318.75 x 1.06

Total price = $337.875

Answer:

It is not.

Step-by-step explanation:

The formula of a right triangle is "[tex]a^{2}+b^{2} =c^{2}[/tex]" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get

  "[tex]30^{2} +122^{2} =125^{2} \\900 + 14884 = 15625\\15784\neq 15625[/tex]

Answer:

90

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

x + 70 =120       {Exterior angle theorem}

        x = 120 - 70

       x = 50

y = x     {Vertically opposite angles}

y = 50

z + 50 + 40 = 180          {Angle sum property}

 z + 90  = 180

          z = 180 - 90

          z = 90

Answer:

4^√16x3

Step-by-step explanation:

Answer:

the slope is 0, m=0

Step-by-step explanation:

do the equation y2 - y1 over x2 - x1

Equation of a line  is the  y = 3x - 1 is with a slope of 3 and a passing point of (2, 5).

Here, slope of line equals 3.

Passing the buck (2, 5)

line equation

(y - y₁) = m (x - x₁)

y - 5 = 3 (x - 2) (x - 2)

y - 5 = 3x - 6

y = 3x - 6 + 5

y = 3x - 1

So, the equation of the line traversing the points (2, 5) and having a slope of 3 is y = 3x - 1.

The complete question is : A line with a slope of 3 passes through the point (2, 5). Write an equation for this line in point-slope form.

Answer:

8  4  2  0

Step-by-step explanation:

Answer:

7/10

Step-by-step explanation:

1/10 = 2/20

1/4 = 5/20

2/5 = 8/20

11/20 = 11/20

We can see that the next term is just 11/20 + 3/20, as 3/20  is added onto each of the next terms.

11/20 + 3/20 = 14/20, which can be simplified to 7/10.

Hope this helps!

Step-by-step explanation:

Principal=1500

Time=18months = 18×12=216

Interest=6%

now

SI=P×T×R÷100

SI=1500×216×6÷100

SI=1944000÷100

SI=19440 is the answer

Answer:

Ms Rios mowed more

Step-by-step explanation:

I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%

Now if her son mowed 14% and it was still at 100% it would be at 86%

So in the end Ms Rios mowed more of her lawn

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.

Example : 6, 7, 8 or 6,34,87

Non-Example : 7, 9, 6

As long as the number is greater than the one before it they are consecutive.

Following this rule I have come up with the numbers :

10, 12, 20

These three numbers are consecutive and equal to 42.

Now to find the largest number in this set just look at the greatest value which would be 20.

I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.

I hope this helps! :)
