Answer:
Step-by-step explanation:
7.50a + 2.50c = 1945
a + c = 364
Use -2.50 for 2nd equation
7.50a + 2.50c = 1945
-2.50a - 2.5oc = -910
5a = 1035
a = 207 adult tickets were sold
207 + c = 1945
c = 1738 child's tickets were sold
You would expect
to be increasing to the left of
, and decreasing to the right, which corresponds to
being positive when
(but near
) and negative when
.
Answer:
<h2><em><u>Option</u></em><em><u> </u></em><em><u>2</u></em></h2>
<em><u></u></em>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Diameter of the cylinder = 12cm
Radius of the cylinder = 12cm ÷ 2 = 6cm
Height of the cylinder = 15cm
<em><u>Therefore</u></em><em><u>, </u></em>
Volume of the cylinder
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Option</u></em><em><u> </u></em><em><u>2</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>correct</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>volume</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>cylinder</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>cubic</u></em><em><u> </u></em><em><u>cm</u></em><em><u>:</u></em>

By the empirical rule, 16% will receive a score below 80 (1 standard deviation below the mean). The other 84%, about 0.84*188 = 158, will receive a score above that value.
About 158 students would receive a score above 80.
