const2013 [10]
X of 20% = y
x - y = 75

x = total amount
y = discounted amount

x * 20/100 = y
x * 0.2 = y
replace y with 0.2x in other equation

x - y = 75
1x - 0.2x = 75
0.80x = 75
x = 75/.8
x = 93.75


Check:
93.75 * 20/100 = 18.75
93.75 - 18.75 = 75
x = 93.75
y = 18.75

Answer: Total amount without discount is $93.75

//BTW not sure about this, but kind of make sense

The number of Internet users in Latin America grew from 25.8 million in 2009 to 70.6 million in 2016. Use the geometric mean to
ipn [44]

Answer:

the annual growth rate is 15.47 %

Step-by-step explanation:

Given the data in the question;

Internet users grew from 25.8 million to 70.6 million,

from the year 2009 to the year 2016.

Using geometric mean, Annual growth rate = ?

To determine the average growth rate of a time series using geometric mean, we use the following formula;

r_{geo = [ ( Xₙ / X₀ )^{\frac{1}{n} ] - 1

where Xₙ is the data value of the last year { 70.6 million }

X₀ is the data value for the first year { 25.8 million }

n is the sample size or the time difference, ( 2016 - 2009 = 7 )

so we substitute;

r_{geo =  [ ( 70.6 / 25.8  )^{\frac{1}{7} ] - 1

r_{geo = [ ( 2.736434  )^{\frac{1}{7} ] - 1

r_{geo = [ 1.15466 ] - 1

r_{geo = 0.15466

r_{geo = ( 0.15466 × 100 )%

r_{geo = 15.47 %

Therefore, the annual growth rate is 15.47 %

According to a​ report, 67.5​% of murders are committed with a firearm. ​(a) If 200 murders are randomly​ selected, how many wou
kolezko [41]

Answer: The answer is 135 murders.

Step-by-step explanation: The report tells us that statistically 67.5% of murders are committed using a firearm. It follows therefore that in a sample of 200 randomly selected murders, one would expect that 67.5% of those would be by a firearm. \frac{67.5}{100} * 200 = 135.

It would certainly be higher that the expected value based on previous data collected but it would not be unusual because one sample may have a higher than "normal" amount of murders by firearm. Statistics aren't going to be exact for every sample.
