Answer:
You don't have a question but I'll answer what I can.
half-life = natural log (.5) / k
half-life = -.693147 / .1247
half-life = 5.561106656
It seems you did not express the k-value properly.
1) A k-value should have a negative value.
2) A k-value should also have units.
For example, the k-value of tungsten 181 is
-0.005723757 / days
Step-by-step explanation:
Answer: There are 350 consumers who purchase frozen yogurt.
Step-by-step explanation:
Since we have given that
Number of consumers polled =360
Number of consumers who purchased ice- cream = 260
Number of consumers who purchased both ice- cream and frozen yogurt = 250
We need to find the number of consumers who purchased frozen yogurt,
Let A denotes who purchased ice-cream
and B denotes who purchased frozen yogurt.
As we know the formula

Hence, there are 350 consumers who purchase frozen yogurt.
