Step-by-step explanation:
Simplifies to:
13.228757n=7n
Let's solve your equation step-by-step.
13.228757n=7n
Step 1: Subtract 7n from both sides.
13.228757n−7n=7n−7n
6.228757n=0
Step 2: Divide both sides by 6.228757.
6.228757n
6.228757
=
0
6.228757
Answer:
Value of the test statistic for this problem = -3.74
Step-by-step explanation:
Here
the sample size n = 1263
and the x = 565
So, the p' -value = 565/1263 = 0.4473
As per the test statistics formula, z value will be evaluated
z = (0.4473-p)/sqrt {p(1-p)/n}
Let us say that p = 0.5
Substituting the given value in above equation, we get -
z = (0.4473-0.5)/sqrt {0.5(1-0.5)/1263}
z = -3.74
Take the root of both sides and solve
1.09544511
1.09544511

Answer:
The half life of the radioactive substance is 277 hours.
Step-by-step explanation:
initial mass, No = 100 mg
mass decayed = 2% = 2 mg
Mass remained , N = 98 mg
time, t = 8 hours
Let the half life is T.
Use the equation of radioactivity
