speed = 14 miles per hour

<u>By</u><u> </u><u>subs</u><u>tituting</u><u> </u><u>the</u><u> </u><u>values</u><u>,</u><u> </u><u>we</u><u> </u><u>get</u>

A group surveyed a mix of people below and above 40 years old about whether or not they visit a dentist once a year. This table
Rama09 [41]

The frequency table that shows the relative frequency of people older than 40 and don't visit the dentist is:

D.                  Visit Dentist Yearly Don’t Visit Dentist Yearly

Below 40                    0.27                         0.73

Above 40                   0.57                          0.43

<h3>What is the relative frequency required?</h3>

The relative frequency of those older than 40 and don't go annually to a dentist can be found as:

= Number of over 40 who don't go to dentist / Total of those over 40 surveyed

Solving gives:

= 13 / (17 + 13)

= 13 / 30

= 0.43

1. A test-tube has a diameter of 3cm. How many turns would a piece of thread of length
Alex Ar [27]

So if we think of a test tube, it looks sort of like a cylinder. This means that its cross-section would be a circle. To find out how many turns a piece of thread would make around the test tube, we need to find the circumference of the test tube, then divide the length of the string by the circumference.

Step 1) Find the circumference

C = pi x diameter

C = 3.14 x 3

C = 9.42

Step 2) Divide the length of the string by the circumference

90.42 / 9.42 = 9.5987

The string would make approximately 9.60 turns around the test tube.

Hope this helps!! :)
