Answer:

30%

Step-by-step explanation:

Total population=15,000

kantipur=9000

gorkhapatra= 7500

Both magazine=40%

n(k intersection g)=40% of 15,000

=0.4*15,000

=6,000

n(k) =9000

n(g)=7500

n(A union B)= n(k) + n(g) -n(k intersection g)

=9000+7500-6000

=10,500

Population who do no read= Total population - n(A union B)

=15000-10500

=4500

Percentage population who do not read both magazine

=4,500/15,000 * 100

=0.3 * 100

=30%

Volume=length times width times height
this should be easy

a.
the volume of a box is 2.5 times 1 times 1 or 2.5 cubic meters

b.
number of boxes times volume per box=volume of container
number of boxes=volumecontainer/volumebox
find volumecontianer
volumecontainer=5 times 2 times 3=30 cubic meters

number of boxes=30/2.5
number of boxes=12
12 boxes needed to fill container


c.
box
1m=100cm
1m by 1m by 2.5m convert so (times everybody by 100)
100cm by 100cm by 250cm
multiply
2,500,000 cubic centimeters

HELP FAST ILL MAKE BRAINIEST Mr. McClellan compared the weights (in pounds) of pairs of elk antlers dropped at Mount St Helens N
Anika [276]
a.1 Line plot for <span>eight of elk antler pairs at Mount St Helens NVM

</span>The diagram is shown in figure 1.

a.2 Weight of elk antler pairs at Rocky Mountain NP

The diagram is shown in figure 2.

b. Calculate the following for each set of data:

We can found the mean (µ) of a set of data points by adding them up and dividing by the number of data points.

b.1 Purple Mean:

Set: \{34, 34, 30, 30, 30, 28, 28, 26\} \rightarrow  \frac{34+34+30+30+30+28+28+26}{8} \rightarrow \boxed{\mu=30}

b2. Red 
Mean:

Set: \{40, 38, 36, 36, 36, 36, 34, 32\} \rightarrow \frac{40+38+36+36+36+36+34+32}{8} \rightarrow \boxed{\mu=36}

b.3 
<span>Red Median
</span>
The Median is the middle of a sorted list of numbers. <span>The median of a finite list of numbers can be found by arranging all the numbers from smallest to greatest. So, arranging the red set we have:
</span><span>
\{32, 34, 36, 36, 36, 36, 38, 40\}

Given that the number of elements is pair, the median can be solved as follows:

</span>\overline{x}=\frac{x_{(n/2)}+ x_{((n/2)+1)}}{2}

∴ n=8
∴ x_{(n/2)}=x_{(4)}=36
∴ x_{((n/2)+1)}=x_{(5)}=36

Then:

\overline{x}=\frac{36+36}{2}=36

b.4 Purple MAD

The Mean Absolute Deviation (MAD) is when you find the distance of each data point from the mean and then find the mean <span>of those distances. So:
</span>
\{34, 34, 30, 30, 30, 28, 28, 26\} has \mu=30
distances=\{4, 4, 0, 0, 0, 2, 2, 4\} \rightarrow \frac{4+4+0+0+0+2+2+4}{8}= \boxed{MAD=2}

b.5 Red MAD

\{40, 38, 36, 36, 36, 36, 34, 32\} has \mu=36
distances=\{4, 2, 0, 0, 0, 0, 2, 4\} \rightarrow \frac{4+2+0+0+0+0+2+4}{8}= \boxed{MAD=1.5}

 c. Calculate the means-to-MAD ratio for the two areas of collection

c.1 Purple set:

The ratio is the<span> relationship between the mean and the MAD indicating how many times the first number contains the second, so:
</span>
\frac{\mu}{MAD}= \frac{30}{2}=\boxed{15}

c.2 Red set:

\frac{\mu}{MAD}= \frac{36}{1.5}=\boxed{24}

d. What inference can be made about the areas in regard to weight of dropped elk antlers? 

MAD tells us how far, on average, all values are from the middle. So, in the example weight of elk antler pairs at Mount St Helens NVM are, on average, 2 away from the middle. On the other hand, weight of elk antler pairs at Rocky Mountain NP are, on average, 1.5 away from the middle. So, we can assure that elk antler pairs at Rocky Mountain NP weighs more than elk antler pairs at Mount St Helens NVM.
