Answer: 2 x - 3 y = 6 i think but let let me know if i'm wrong
Answer:
the answer is 9×9 and -9×-9
Answer:
B.) This is not a binomial experiment, because the number of trials is not fixed.
Step-by-step explanation:
For a certain experiment to be classed as a binomial, it has to meet some criteria ;
Which include ;
1.) The trials should be independent.
11.) Each trial should be classifiable into one of success of failure.
111). There is a fixed mean probability for success and failure
IV) There is a fixed number of trials, in experiment described above, the number of trials isn't fixed, it is variable, as the trial will continue until a defective item is obtained.
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
<em>A = 84 mg</em>
he would have traveled 210 miles because in half an hour he would have traveled 30 miles and in 3 hours he would have traveled 180 miles. so we have to add those up and we get our answer: 210 miles
