The are 9 pieces of data in the set so we have:
(27+32+14+19+24+26+22+32+29)/9 = 25
25 is the mean of the set of data.
The half life formula is :
where N(t) = remaining quantity after t years
No = Original Quantity
t = time in years
T = half life in years
From the problem, we have :
N(t) = 30 grams
No = 100 grams
T = 674
Solve for t :
Take ln of both sides :
The answer is t = 1170.71 years
Answer:
Using the slope-intercept form, the slope is 2 .
Step-by-step explanation:
To solve this problem, you need to do it in this order: PEMDAS
(Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
2 × 4 ÷ 6(8 × 3) - 6 = Y First simplify inside the ( ), and multiply 8 by 3
2 × 4 ÷ 6(24) - 6 = Y Now multiply 6 and 24
2 × 4 ÷ 144 - 6 = Y Multiply 2 and 4
8 ÷ 144 - 6 = Y Divide 8 and 144
18 - 6 = Y Subtract 18 and 6
12 = Y
