Answer:
A=200.96 in2
Step-by-step explanation:
A=PI x R2
A=3.14 x 8 in x 8 in
a=200.96 cm
Answer:
A.105°
Step-by-step explanation:
Angle at W and V are equal and the angles at T and U are also equal
Hence taking angles at T and U...so as to calculate the value of x
5x + 15 = 3x + 21
5x - 3x = 21 - 15
2x = 6.....hence, x = 3
Then for the angle of VXU;
All angles in a triangle add up to 180°
15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU
180 - 75 = 105°
The answer is A. It is .015 between .19137 and .17637 and also between .17637 and .16137.

Answer:
the graph increases
Step-by-step explanation:
If you read your problem statement, you find it tells you the answer:
"... point A and then continues to increase through B"
That is, between points A and B, ...
the graph increases
Let's test choice A.
<span>The 13- to 15-year olds spent an average of 14 hours studying last week.
</span>(6 + 7 + 8 + 10 + 12 + 12 + 12 + 13 + 14 + 14)/10 = 10.8 = average
The 13- to 15-year olds spent an average of 10.8 hours studying last week. not 14. Thus, Choice A is incorrect.
Let's test Choice B.
<span>The median value for the hours spent studying last week for the 13- to 15-year olds is greater than the median value for the hours spent studying last week for the 16- to 18-year olds.
The median is found by finding the middle number/set in the data given. Observe.
</span><span>13- to 15-year olds: 6, 7, 8, 10, (12, 12,) 12, 13, 14, 14
12 + 12 = 24/2 = 12
Median: 12
</span><span>16- to 18-year olds: 3, 8, 9, 9, (9, 10,) 13, 14, 15, 18
9 + 10 = 19/ 2 = 9.5
Median: 9.5
Therefore, Choice B is true since the </span><span>median value for the hours spent studying last week for the 13- to 15-year olds is greater than the median value for the hours spent studying last week for the 16- to 18-year olds.
As for Choices C and D, they are incorrect. C is incorrect because the range of the 13- to 15-year olds is 14 - 6 = 8 and the range of the </span>16- to 18-year olds is 18 - 3 = 15. So this means, <span>The range for the hours spent studying last week for the 13- to 15-year olds is NOT the same as the range for the hours spent studying last week for the 16- to 18-year olds. Thus, C is incorrect.
D is incorrect because the mode</span> for the 16- to 18-year olds is 9 and the mode for the 13- to 15-year olds 12. Thus, t<span>he mode for the hours spent studying last week for the 13- to 15-year olds is NOT less than the mode for the hours spent studying last week for the 16- to 18-year olds. Therefore, D is incorrect. </span>
In conclusion, Choice B is the correct answer.
Happy Studying!
