Answer:
It's A
Step-by-step explanation:
Got it right on the practice :)
Keep in mind that means is the same as asking for the average. all you need to do is add all the values and divide them by the number of values, which is 5
<span>$39.99 + $31.99 + $19.99 +$23.99 + $26.99= 142.95
mean= 142.95/5 = 28.59</span>
R=S*0.5^(t/8)
<span>R is the remaining amount </span>
<span>S is the starting amount (500) </span>
<span>0.5^ is for the HALF in half-life </span>
<span>t/8 show that every 8 ts (every 8 hours), it will be halved once </span>
<span>...so plug in 500mg for the general solution... </span>
<span>R=(500)*(0.5)^(t/8) </span>
<span>... plug in 24h to solve for after 24h </span>
<span>R=(500)*(0.5)^(24/8) </span>
<span>R=(500)*(0.5)^(3) </span>
<span>R=(500)*(0.125) </span>
<span>R=(0.0625) </span>
<span>...therefore there with be 0.0625 mg of the dose remaining</span>
Answer:
the answer for 92-53.3 is 38.7
Slope = (0 - 4)/(-5-5) = -4/-10 = 2/5
y = mx + b
4 = (2/5) (5) + b
4 = 2 +b
b = 2
equation
y = 2/5x + 2
