PART A. Answer: 12.5 cm. Explanation. For every 2 kilometers, there are 5 centimeters. 5 kilometers is 2.5 times more than 2 kilometers. So you multiply 5 centimeters by 2.5 and that is the answer.
PART B Answer: .8 km. Explanation. If you divide 5cm by 2, you get 2.5. So divide 2km by 2.5 and that is how you get .8.

Answer:
Step-by-step explanation:
Given that the weights for a population of North American raccoons have a bell-shaped frequency curve with a mean of about 12 pounds and a standard deviation of about 2.5 pounds
Since bell shaped is given we can assume that this follows a normal distribution symmetrical about the mean.
To find 95% two values we can use Z critical value for 95%
i.e. ±1.96
95% will lie between 12±1.96(2.5)
= 12±4.9
=(7.1, 16.9)

Answer:
Thus, Amit ran 3.33 KM
calculation needed:
conversion of time (40 minutes to hour)
multiplying velocity and time (which we got in hours)
Step-by-step explanation:
Given
to calculate the distance: . v times t
that is multiply v with t
where v is average velocity
t is the time
__________________________________
Given
v = 5 km/hour
time = 40 minutes
since speed is in Km per hour and also we have to find distance in km
lets convert time which in 40 minutes to hour
we know
60 minutes = 1 hour
1 minute = 1/60 hour
40 minutes = 40/60 hour = 2/3 hour
distance = v times t
distance = 5*2/3 = 10/3 = 3 1/3 km = 3.33 km
Thus, Amit ran 3.33 KM
calculation needed:
conversion of time (40 minutes to hour)
multiplying velocity and time (which we got in hours)
