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
Y - y₁ = m(x - x₁)
y - 1 = -2(x - 3)
y - 1 = -2(x) + 2(3)
y - 1 = -2x + 6
+ 1 + 1
y = -2x + 7
The answer is A.
Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
Answer:
11
Step-by-step explanation:
248/24=10.3
round up to 11
The number in brackets represents the percentage change
1.045
the 1 shows that it is an increase and the .045 shows the percent
for example 1.55 would be 55% increase and 1.555 would be 55.5% increase
