Answer:
x = -1 and x= 14
Step-by-step explanation:
x^2 -13x -14=0
x^2 + x- 14x -14 = 0
x(x+1) -14(x+1) = 0
(x+1)(x-14) =0
x+1 = 0
x= -1
x-14=0
x= 14

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 = 
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
