Answer:
15
Step-by-step explanation:
Scale Factor = 3
Using Formula:
Scale Factor = LengthOfDilatedTraingle/LengthOfActualTriangle
Scale Factor = B'C'/B'C'
B'C' = 3 * 5
B'C' = 15
Answer:

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
Step-by-step explanation:

Answer:
Your median is 40
Step-by-step explanation:
Answer:
7/20. or .035 as a decimal
Step-by-step explanation:
the 2 subtractions would cancel out so it would be -1/4+3/5. then you would times both equations by the opposite bottom number which would turn into -5/20+12/20 which is just -5+12 all under 20 which then when you add -5 and 12 it would be 7. so its 7/20
