Answer:
20.48% probability that she will see exactly two black squirrels out of the five
Step-by-step explanation:
For each squirrel, there are only two possible outcomes. Either it is black, or it is not. The probability of a squirrel being black is independent of other squirrels. So we use the binomial probability distribition to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
20% of squirrels are black.
This means that 
What is the probability that she will see exactly two black squirrels out of the five?
This is P(X = 2) when n = 5. So
20.48% probability that she will see exactly two black squirrels out of the five

Answer:225000 mice
Step-by-step explanation:
Mass of elephant=4500kg
Mass of mice=2x10^(-2)=2/100 kg
Let y be there number of mice
2/100 x y=4500
2y/100=4500
Cross multiply
2y=4500 x 100
2y=450000
Divide both sides by 2
2y/2=450000/2
y=225000
Answer:
C. I,II,III
Step-by-step explanation:
Absolute value is the distance of a number from 0 on a number line. 6 is 6 units from 0, therefore this option is correct. -6 is 5 units to the left of 0, but it is still 6 units away, therefore this option is correct. 6 is 6 units away from 0, therefore, III is correct. But 0 is 0 units away from 0, therefore this option is incorrect.
6. If 55% of the selling price is markup, the remainder (45%) is the cost. Gaitan can pay up to 45% of 489.50 = $220.28.
7. If 52% of the selling price is markup, the remainder (48%) is the cost. 48% of the selling price is $38.87.
... 0.48 × selling price = cost
... selling price = cost/0.48 = $38.87/0.48 = $80.98
8. If 40% of the selling price is markup, the remainder (60%) is the cost, $12.95.
... 0.60 × selling price = $12.95
... selling price = $12.95/0.60 = $21.58
9. If 35% of the selling price is markup, the remainder (65%) is the cost.
... 0.65 × $24.00/dz = $15.60/dz
10. If 60% of the selling price is markup, the remainder (40%) is the cost. Veronica can pay up to 40% of $600.00 = $240 for the jacket.
