A student solves a problem correctly 40 times out of 72 tries. Based on this data, what is the probability that the student inco

suter [353]

Answer:

The probability of the student incorrectly solves the next problem is 44%.

Step-by-step explanation:

Let E be the event of solving a problem correctly.

Then E' is the event that the problem is solved incorrectly.

Now, recall the definition of probability.

probability of an event = $\frac{number of favorable events}{total number of events}$

So,

p(E) = $\frac{40}{72}$

Also,

p(E) + p(E') = 1 and

p(E') = 1 - p(E)

= 1 - $\frac{40}{72}$

= $\frac{72-40}{72}$

= $\frac{32}{72}$

= $\frac{4}{9}$

= $\frac{4}{9} (100)$

= 44% rounded.

Hence, the probability of the student incorrectly solves the next problem is 44%.

The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year

dezoksy [38]

We can make use of the general formula for the geometric series to generate the function representing the average annual salary.
an = a0(r)^(n-1)

Or
f(x) = a0(r)^(x - 1)

Plugging in the given values for the year 2005 and 2006 to ge the value of r.
82000 = 70000 (r)^(1-1)
r = 1.1714

Therefore, the function is:
f(x) = 70,000 (1.1714)^(x-1)
