Answer:
x = -1
Step-by-step explanation:
<h2>
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get <u>x = -1</u>

Answer :
0.2322
Step-by-step explanation:
Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4
p = 0.4
1 - p = 1 - 0.4 = 0.6
Number of samples, n = 8
P(x = 4)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 8C4 * 0.4^4 * 0.6^4
P(x = 4) = 70 * 0.0256 * 0.1296
P(x = 4) = 0.2322432
P(x = 4) = 0.2322
Answer:
21
Step-by-step explanation:
Fine the average rate of change by the difference in N over the difference in T:
3000 - 500 / 4-0 = 2500 / 4 = 625
This means for every 1 T, N = 625.
Now multiply 625 by 8:
625 x 8 = 5000
When T = 8 N = 5,000
The decay rate can be found by dividing -ln(2) by the half life.
Decay rate = -ln(2) / 5715 = -0.00012
