Step-by-step explanation:
you would do 3 ÷ .99 and then when you get the answer from that you would multiply it by 5.
Answer:
a
The null hypothesis is 
The alternative hypothesis is 
b
The sample proportion is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 546
The number of people that use a laptop overnight is 
The population proportion is 
Generally
The null hypothesis is
The alternative hypothesis is
Gnerally the sample proportion is mathematically represented as
=> 
=>
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
Answer:
57.06 unit^2
Step-by-step explanation:
find the area of the rectangle = 12*12 = 144 unit^2
the area of the circle = pi*r^2 = 3.14*8^2 = 201.06 unit^2 (rounded to the nearest hundredth)
then the "shaded area" is the difference
201.06 - 144 = 57.06 unit^2
Answer:
<u><em>As the penny falls 320 meters, its vertical velocity increases at the rate of 9.8 m/s each second. Use the following equation to determine its speed when it hits the ground. </em></u>
<u><em>
</em></u>
<u><em>vf^2 = vi^2 + 2 * a * d, vi = 0 </em></u>
<u><em>vf^2 = 2 * 9.8 * 320 </em></u>
<u><em>vf = √6272 </em></u>
<u><em>
</em></u>
<u><em>This is approximately 79 m/s. I hope this helps you to understand how to solve this type of problem.</em></u>
