Answer:
1). 
2). 0.81
3). 81%
Step-by-step explanation:
There are total 10×10 = 100 squares in the picture and number of shaded squares = 100 - 19 = 81
Shaded area expressed as the fraction of the whole = 
Shaded area in decimals of the whole = 
Shaded area in percent of the whole =
= 81%
Answer:
30
Step-by-step explanation:
2 out of 30 were defective. The percentage rate is found by dividing 2 by 30 and then multiplying by 100, so that would be:
Percentage Defective Rate = 2/30 * 100 = 6.67%
Now, we have to find the expected defective number of bulbs in a total of 450. So we find 6.67% of those. That would be the decimal (0.0667) multiplied by 450:
0.0667 * 450 = 30
So, out of 450 bulbs, 30 would be expected to be defective
