First you put the numbers in order from least to greatest.
2,3,4,5,9,10,12,12
The median is the very middle number. Since the median is between 5 and 9, you find the mean of 5 and 9. 5+9=14 14/2=7. The median is 7

A hospital uses cobalt-60 in its radiotherapy treatments for cancer patients. Cobalt-60 has a half-life of 7

NeTakaya

Answer:

We have 197 g of Co-60 after 18 months.

Step-by-step explanation:

We can use the decay equation.

$M_{f}=M_{i}e^{-\lambda t}$

Where:

M(f) and M(i) are the final and initial mass respectively
λ is the decay constant (ln(2)/t(1/2))
t(1/2) is the half-life of Co
t is the time at the final amount of m

$M_{f}=228e^{-\frac{ln(2)}{7} 1.5}$

$M_{f}=197\: g$

<u>Therefore, we have 197 g of Co-60 after 18 months.</u>

I hope it helps you!

Wazma bought some new pants, but the 34 inch inseam was too long. If he wants the inseam to be 3013 inches long, how much length

KiRa [710]

The length of the inseam to be removed from the pant is 3 2 / 3 inches.

<h3 /><h3>How to find the length to be removed?</h3>

The length of the pant he bought is 34 inches and it was too long.

He wants the length to be 30 1 / 3 inches long.

Therefore, the amount of length to be removed can be calculated as follows;

34 - 30 1 / 3

$30\frac{1}{3} = \frac{91}{3}$

Hence,

$34-\frac{91}{3}=\frac{102-91}{3} =\frac{11}{3}=3\frac{2}{3} inches$

Therefore, the number to be removed is 3 2 / 3 inches
