An electronics retailer receives a shipment of 6,000CDs to distribute to its stores. A quality control manager inspects a random
Alex17521 [72]

Answer: 300

Step-by-step explanation:

Given , An electronics retailer receives a shipment of 6,000CDs to distribute to its stores.

i.e, Total CD's he has now = 6,000

Also, a quality control manager inspects a random sample(S) of 40CD's , the number of defective(D) CD's are 2.

Then , the proportion of defective( D) CD's = \dfrac{D}{S}=\dfrac{2}{40}=0.05

Now , the number of CDs in the shipment are likely to be defective = ( Total CD's) x (proportion of defective CD's)

= 6000 x 0.05

=300

Hence, the number of CDs in the shipment are likely to be defective  =300

What number must be added to the expression below to complete the square? x2 - 11x
mart [117]

Since we are to complete the square, therefore I believe the correct given should be:

x ^ 2 – 11 x

Take note of the symbol ^ which denotes that 2 is an exponent of x.

The general form of a binomial equation is in the form of:

a x^2 + b x + c

Where in this case:

a = 1

b = -11

c = unknown

To complete the square, we have to find for the value of c. This is calculated using the formula:

c = (b / 2) ^ 2

c = (-11 / 2) ^ 2

c = 30.25

Therefore the complete equation is:

<span>x ^ 2 – 11 x + 30.25</span>

A terrorist planted an armed nuclear bomb and your job is to disabled it . There are 4 wires to the device. You will disable the
Vesnalui [34]

1/6

Step-by-step explanation:

  • According to the question, the right combination of 2 wires cut (out of the 4 wires ) will defuse the bomb. To find all the possible combinations we using the following formulae;

nCr = n! / r! * (n - r)!

⁴₂C = 4! / 2! * (4-2)!

⁴₂C = 24 / 2 * 2

⁴₂C = 6

  • There are a possible 6 combinations
  • Therefore for probability of cutting the right combination of 2 wires is 1/6
