Answer:
equation: 10 + 0.05x=22
Step-by-step explanation:
the next step after writing the equation would be to subtract 10 from both sides to get 0.05x=12. after this you would then have to divide 12 by 0.05 to get 240 minutes. you could check it by putting 240 in for x to get 10+0.05(240)=22. you would then multiply 0.05 by 240 to get 12 and then add 10 onto it to get 22 which was already given.
55.50/ 10 boxes =5.50 that is cost of 1 box.
Using the probability concept, it is found that there is a
probability that “Relaxation Through Mathematics” is first to review.
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- There is a total of k documents to be reviewed, hence
. - Of those documents, 1 is named “Relaxation Through Mathematics”, hence

The <em>probability </em>is:

What about that??? I don't what to solve for
Using the critical point concept, it is found that a = -3 and b = 7.
<h3>What are the critical points of a function?</h3>
- The critical points of a function are the values of x for which:

In this problem, the function is:

Hence, the derivative is:

Then:







Since the critical point is at x = 2, we have that:




Then:

Critical point at (2,3) means that when
, then:
