The lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
Step-by-step explanation:
This is because the range is greater and the minimum and maximum are higher numbers.
Answer:
Radius: 2.3 in
Circumference: 14.1 cm
Step-by-step explanation:
Radius is half of the diameter.
Diameter=4.5
Radius=4.5/2=2.25, which rounds to 2.3
Circumference=
d
=(3.14)(4.5)
=14.13
=rounds to 14.1
The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,
We substitute t = 64 in the expression.
A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg
