<span>The solution would be like this for this specific problem:

</span>( \frac{30}{46}) * ( \frac{29}{45}) * ( \frac{28}{44}) *( \frac{27}{43})  = 0.168

 

<span>The probability that at least one of the 4 calculators in the sample is defective is complement of 0.168 so the answer is 0.832.</span>

BD=16 and ÁT is the<br> perpendicular bisector of BD. Y=?
iren2701 [21]

Answer:

y= 5

Step-by-step explanation:

Given

BD = 16

BC = 2y - 2

CD = y + 3

Required

Find y

BD = BC + CD

So, the expression becomes

16 = 2y - 2 + y + 3

Collect like terms

16 = 2y  + y- 2 + 3

16 = 3y+1

Collect like terms

3y = 16 - 1

3y = 15

Make y the subject

y= 15/3

y= 5

What is the average velocity between 12.00 and 15.00 seconds
bekas [8.4K]

The average between 12.00 and 15.00 seconds
can be defined in a few different ways.

Way #1:  (speed)

     Average speed =
         (1/2) (the speed at 12 seconds  +  the speed at 15 seconds) .


Way #2:  (speed)

   Average speed =
       (1/3) (the distance covered between 12.00 and 15.00 seconds)


Way #3:  (velocity)

   Average velocity =
     (1/3) (distance between location at 12 sec and location at 15 sec)
       in the direction from location at 12 sec to location at 15 sec.


That's the best we can do with the combination of given and
not given information in the question.
