Answer: half life = 1.98 seconds
Step-by-step explanation:
Given that the amount of sodium-24 in the patient’s body in milligrams after t hours is given by
S(t) = 5e–0.35t.
From the equation above, decay constant K = 0.35
Half life = ln2/K
Half life = ln2/ 0.35
Half life = 1.98 seconds
Hello Jordan
Let me help you out
y= 5x - 6
Let's flip it
5x - 6 = y
5x = y + 6
x= ( y+6)/5
x= 1/5 y + 6/5
Have a good day dude !
Answer: A. (3x+8)(3x−8)
Step-by-step explanation:
Variance is the average of the square of the differences of each data with the mean. To calculate for the variance, we first calculate for the mean. Then, we subtract each data with the mean. Next, each difference would be squared and added. The resulting value would be divided on how many data are used. We calculate as follows:
Mean = <span>9 + 7 + 6.5 </span>+ 7.5 + 7 + 8 + 5 + 6 + 7.5 + 8 / 10
Mean = 6.4
Squared of the sum of the differences = (9-6.4)^2 + (7-6.4)^2 + (6.5-6.4)^2 + (7.5-6.4)^2 + (7-6.4)^2 + (8-6.4)^2 + (5-6.4)^2 + (6-6.4)^2 + (7.5-6.4)^2 + (8-6.4)^2 = 17.15
Variance = 17.15 / 10 = 1.715
