Answer:
The percentage increase in Jayana's postcard collection is 15%
Step-by-step explanation:
Jayana had 20 postcards last year
With 3 more postcards this year
From the given equation Quantity = Percent x Whole
Here;
Let P = Percent/100%
Quantity = Increment in postcard = 3 postcards
Whole = The total postcards from last year = 20 postcards
Hence,
3 postcards = P x 20 postcards
P = 3/20 = 0.15
Recall P = Percent/100%
∴ Percent = P x 100% = 0.15 x 100% = 15%
The percentage increase in Jayana's postcard collection is 15%
Answer:
<em>hello your question lacks some information attached below is the complete question</em>
answer : NO
Step-by-step explanation:
Determine the probability of not selecting an obese subject in 3 trials

= 0.703
The probability > 0.05
hence it is insignificant therefore the answer is NO
Answer: 1/3 is already the lowest term.
