Let me help you visualize this one.
Let's say we have 12 chickens.
OOOOOOOOOOOO
We divide this group in half (1/2 who tried to cross the road.)
OOOOOO
And here, we need to get 3/4 of the 6 left.
3/4 can be represented as 0.75 of 1.
6 times 0.75 equals to 4.5.
OOOOC (Woah, that chicken is split in half!)
What fraction is 4.5 of the original amount?
Well, that's for you to find out! Good luck in solving this question.
Answer:
10,000,000
Step-by-step explanation:
you round up, so that makes it 10,000,000
Answer: 0.0668
Step-by-step explanation:
Given: Mean : 
Standard deviation : 
The formula to calculate z-score is given by :_

For x= 4 minutes , we have

The P-value = 
Hence, the probability that on a given run, the time will be 4 minutes or less = 0.0668
The mass of orangutan is 64.5 kilograms
<em><u>Solution:</u></em>
Given that orangutan weighs 142 pounds
Also given that,
1 kilogram is equivalent to about 2.2 pounds
Now let us convert 142 pounds to kilograms
1 kilogram = 2.2 pounds

Therefore, 142 pounds is equivalent to,


On rounding to nearest tenth we get, 64.5 kilograms
Thus mass of orangutan is 64.5 kilograms
