<em><u>Explanation</u></em><em> </em><em>:</em>
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
Answer:
A. 16.55
Step-by-step explanation:
What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.
21 * sin(38)
<em>sin(38) calculates to 0.615661475.</em>
21 * 0.615661475
<em>Multiply 21 by 0.615661475</em>
side a = 12.928890975
Now to find x. Use this to find x: √21² - 12.928890975²
√21² - 12.928890975²
<em>Square both numbers</em>
√441 - 167.156221843
<em>Subtract 167.156221843 from 441</em>
√273.843778157
<em>Find the square root of 273.843778157</em>
x ≈ 16.548225831
x ≈ 16.55, so the answer is A.
The median is the middle score, it is also the average of the two middle scores when total number is even.
original 3 scores: 89, 90, 95 ----> median = 90
with final score: 89,90,X,95 ----> median = 91.5
(90+x)/2 = 91.5
90+x = 183
x = 93
Final score was a 93.
It's an expression that can be simplified to read
( 0.7 x 0.4 ) ( b³ x b⁹ )
= ( 0.28 ) ( b¹² ) = 0.28 b¹² .
