Answer:
580
Step-by-step explanation:
Let's translate this word for word.
87 is 15% of what number
87 = 15% times x
87=.15 times x
Divide both sides by .15
Cancel out the common factor of .15 on the right; that is .15/.15=1.
580 is the number
Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.

Answer:
1. c.
2. a.
3. b.
Step-by-step explanation:
Remember f(x) = y
1. f(x) = y = 2/5x+8
2. f(x)= y - 8 = x => y = 8 +x
3. f(x) = y = x - 8
This is my answer. I can to screenshot it as it would not let me post.
Answer 1 / 25
Step-by-step explanation:
The probability that the first
of the three mutants will take over the population = 2 / 100
The probability that the second
of the three mutants will take over the population = 1.01 / 100
The probability that the third
of the three mutants will take over the population = 0.99 / 100
Therefore, the probability that each of the three mutants will take over the population = probability of the first,second or third = 2 / 100 + 1.01 / 100 + 0.99 / 100 = (2+1.01+0.99)/100 = 4 / 100 = 2/25
