A factory inspector found flaws in 3 out of 18 wooden boxes. What is the experimental probability that the next wooden box will be flawed?

Write your answer as a fraction or whole number.

-------------------------------------------------------------------------------------------------------------

Remember, The experimental probability is the number of times an event occurs out of the total number of trials.

-------------------------------------------------------------------------------------------------------------

Flawed Boxes / Total

=3/18

=1/6

So The Answer is 1/6

The experimental probability that the next wooden box will be flawed is 1/6=0.167.

The experimental probability of an event is the ratio of the number of outcomes in which a specified events occurs to the total trials.

Mathematically, Experimental probability= f/n, where f is the number of times an event occurs, n is the total number of trials.

Total number of wooden boxes= 18

Total number of boxes that are flawed= 3

Therefore, required experimental probability = 3/18

                                                           =1/6

Hence, the experimental probability that the next wooden box will be flawed= 1/6

Answer:

Step-by-step explanation:

The weight of the other tiger is 11x - 14.

The total weight of the two tigers is 16x + 3.  Subtract the weight of one (5x + 17) from this total; the result is the weight of the other tiger:

  16x + 3

-  ( 5x + 17)

----------------

 11x - 14

The weight of the other tiger is 11x - 14.

Answer:

f(2) = 12

f(x) = 7, x = -3, 1

Step-by-step explanation:

a)

plug in x as 2

f(x) = 2^2 + 2(2) + 4

f(x) = 4 + 4 + 4

f(x) = 12

b)

replace f(x) with 7

7 = x^2 + 2x + 4

x^2 + 2x - 3 (move 7 to other side)

Factor

ac: -3x^2

b: 2x

split b into 3x, -x

(x^2 -x) + (3x - 3)

    ↓             ↓

  x(x-1)  +  3(x-1)

Factor: (x-1)(x+3) = 0

Solve using Zero Product Property:

x - 1 = 0, x + 3 = 0

Answer:

12 cubes

Step-by-step explanation:

To find out how many cubes can fit into the rectangular prism, we need to find the volume.

Volume is Length × width × height

[tex]6[/tex]×[tex]2[/tex]×[tex]1=12[/tex]

The volume is 12 units cubed.

We can fit 12 1-centimeter cubes in the rectangular prism.

Answer:

The ball will be at a height of 3 feet above the ground after 3.729 seconds.

Step-by-step explanation:

Let suppose that the tennis player has hit the ball vertically, meaning that ball will experiment a free fall, that is, an uniform accelerated motion due to gravity. The time taken by the ball in terms of its initial velocity ([tex]v_{o}[/tex]), in feet per second, initial position ([tex]x_{o}[/tex]), in feet, final position ([tex]x[/tex]), in feet, and gravitational acceleration ([tex]g[/tex]), in feet per square second is described by this second order polynomial:

[tex]x = x_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g\cdot t^{2}[/tex] (1)

If we know that [tex]x_{o} = x = 3\,ft[/tex],  [tex]v_{o} = 60\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the time needed by the ball to be at a height of 3 feet again is:

[tex]3\,ft = 3\,ft + \left(60\,\frac{ft}{s} \right)\cdot t + \frac{1}{2}\cdot \left(-32.174\,\frac{ft}{s^{2}} \right)\cdot t^{2}[/tex]

[tex]-16.087\cdot t^{2}+60\cdot t = 0[/tex] (2)

[tex]t^{2} - 3.729\cdot t = 0[/tex]

[tex]t \cdot (t -3.729) = 0[/tex]

The binomial contains the time when the ball will be at a height of 3 feet again. In other words, the ball will be at a height of 3 feet above the ground after 3.729 seconds.

4/10 or 2/5 or if you want, 0.4

Step-by-step explanation:

They both are tenths so, all you have to do is subtract 7-3. 7-3 is 4 so, the answer would be 4/10. 4/10 simplified is 2/5. I hope this helped.
