Answer:

<h2>"73% of the students play sports as recreational activity".</h2><h2>"The majority of students prefer sports as recreational activity".</h2>

Step-by-step explanation:

According to the table, 73 people have sports as recreational activity. Observe that the total number of students is 73 + 14 + 13 = 100.

So, 73 of 100 students prefer sports as recreational activity, this represents 73/100= 0.73 (73%).

So, one reasonable inference is that "73% of the students play sports as recreational activity".

Now, based on this percentage representation, we can also say that "the majority of students prefer sports as recreational activity".

A jeweler wants to minimize business costs and has found that the average cost in dollars per necklace is given by C(x)=0.5x^2-7
Vika [28.1K]

Answer:

The maximum cost is 41 dollars per necklace.

Step-by-step explanation:

The average cost in dollars/necklace is given by :

C(x)=0.5x^2-7x+65.5  .....(1)

Where

x is the number of necklaces that are created

To maximize the cost, find the value of x by putting dC/dx = 0

\dfrac{d}{dx}(0.5x^2-7x+65.5)=0\\\\x-7=0\\\\x=7

Now put the value of x = 7 in equation (1).

C(x)=0.5(7)^2-7(7)+65.5\\\\=41\ \text{dollars per necklace}

Hence, the maximum cost is 41 dollars per necklace.
