If your asking what the price of something is, that was originally 29.99, and has been marked down by 33.33%, the easy way to do this is to take 30 and multiply it by 1/3, resulting in 20. The proper way is to take your calculator and multiply 29.99 by 0.333, resulting in roughly 9.98, meaning the price you pay is 20.00. Either way, your still going to pay $20 for the item.
Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of 
, that is, coming from A.
0.05 of 
, that is, coming from B. So
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Answer:
12
Step-by-step explanation:
Answer: 1 1/20
Step-by-step explanation:
1/2 / 5/8 + 1/4
=8/10 +1/4
=21/20
=1 1/20
Answer:
35
Step-by-step explanation:
A quadratic sequence is a form. of mathematical progression of numbers in which the subsequent differences between each consecutive term differ by the exact amount. This is known as the common second difference.
Hence in this case,
we have
S= 3+8+15+24+…..+Tn - 1.
S=. 3+8+15+……………..Tn-1 + Tn
Deducting 2nd series from the first
We have 0=3+5+7+…….Tn
Hence, we have Tn= n (n+2)
= 24 (9+2)
= 24 + 11
= 35
