Which best describes the diameter of a circle?
<em>Statements</em>
<u><em>A. The distance from the center to any point of the circle</em></u>
This statement describes the radius of the circle
<u><em>B. The length of a chord that contains the center of the circle</em></u>
This statement describes the diameter of the circle
<u><em>C. The distance around the circle</em></u>
This statement describes the circumference of the circle
<u><em>D. The length of a chord that does not contain the center of the circle</em></u>
This statement describes a line segment linking any two points on a circle that does not contain the center of the circle
therefore
<u>the answer is the option</u>
B. The length of a chord that contains the center of the circle
Given:
Machine dispenser
Average = 600 mL soda to every glass
Volumes recorded in one day (random sampling)
600.15
599.92
599.85
599.92
599.81
600.14
600.04
599.98
Average = (sum of the volumes)/(number of readings)
= 4799.81/8
Average = 599.976 mL
Therefore there is sufficient evidence to conclude that the average volume of soda dispenser is different from 600 mL.
Answer:
EA, or s
Step-by-step explanation:
The line AE could also be named any of the following:
AC, EC, CE, CA, EA
If you’re only looking at the line segment AE, the only option is:
EA
Since I don’t know whether you need the line or line segment, you might want go with EA since it’s on both lists. It could also be line s.
Answer:
21
Step-by-step explanation:
To find the area of a cylinder you mutliply radius by height.
r*h = 162
If we know the height is 7.7, substitute it for <em>h.</em>
r*7.7 = 162.
Or:
162 / 7.7
Which gives you 21.03, or 21.
Answer:
The average temperatures were:
- <u>New York City: 63</u>
- <u>San Francisco: 64</u>
Step-by-step explanation:
Remember that, the average is obtained in the form below:
- Average = The sum of all the values / the number of values.
In this case, the number of values is 12 because are the number of months in the year. The sum of values is shown below for each case:
- <u>Average temperature in New York City = (39 + 42 + 50 + 61 + 71 + 81 + 85 + 84 + 76 + 65 + 55 + 47) / 12 = 63.
</u>
- <u>Average temperature in San Francisco = (57 + 60 + 62 + 63 + 64 + 67 + 67 + 68 + 70 + 69 + 63 + 58) / 12 = 64.</u>
I don't add units because the table doesn't specify if they are Celsius, Fahrenheit, or others.
