Answer:
20 %
Step-by-step explanation:
% Increase = Increase/Original value × 100 %
Data:
Original = $25
This year = $30
Calculations:
Increase = This year - original
= 30 - 25
= $5
% Increase = 5/25 × 100 %
= 20 %
The percent increase of the price of the necklace was 20 %.

I hope this helps. I don't quite know what you're looking for.
Step-by-step explanation:
25 x 13 = 325
325 divided by 25
= 13 twenty fifths.
49 x 11 = 539
539 divided by 11
= 49 elevenths
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer: 0.8926
Step-by-step explanation:
Given : A shipment of 50 inexpensive digital watches, including 10 that are defective.
The probability that a digital watch is defective 
Sample size : n=10
Also, they reject the whole shipment if 1 or more in the sample are found defective.
Using the binomial probability formula :

Let x be the random variable that represents the number of defective watches.
The probability that the shipment will be rejected :-

Hence, the probability that the shipment will be rejected = 0.8926
