Answer:
Option 3rd is correct that is 
Step-by-step explanation:
Since, the pennant has three points it is in triangular shape since, have three points
Triangle is enclosed figure.
As we know the sum of interior angles of triangles is 
Therefore, Option 1,2,4 are discarded.
Hence, Option 3rd is correct.

Answer:
The sides of the original rectangular prism have been increased by a scale factor of 4
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z----> the scale factor
x---> volume of the increased rectangular prism
y---> volume of the original rectangular prism

substitute

-----> the scale factor
therefore
The sides of the original rectangular prism have been increased by a scale factor of 4
Answer:
1/5
Step-by-step explanation:
Since it is starting with negatives, the pattern is actually increasing. They are adding 1/5 each time
Answer:
15.39%
Step-by-step explanation:
Step 1
Find the z-value associated to the given datum x, in this case x = 28 mpg
<em>z is given by the formula
</em>
where
is the mean of the distribution and
is the standard deviation. In this case,
Step 2
Locate the z-value in the table of z-values of the normal distribution.
(See table attached) and read the number corresponding to this z-value. In this case is highlighted in the table and its value is 0.34614.
<em>This numbers gives us the % of vehicles with a mpg between 0 and 28.
</em>
Step 3
As we know that the total area under the curve for z > 0 is 0.5, then we have to subtract 0.34614 from 0.5 to obtain the % of cars with a mpg greater than 28 mpg.
0.5 - 0.34614 = 0.15386
so, the % of 2016 vehicles that have better gas mileage than the Beetle's gas mileage is 15.39 % (rounded to two decimals)
