Answer:
Should be 4.0(Not sure tho. my thought process is complicated but to me it makes sense)
Step-by-step explanation:
If y=10 and x =2.5, if y were to = 20, then x would equal 5. so you take that ratio, and say 6 is 3/5's the way to 10, so you also divide 2.5 by 3/5
you get 1.5, you add that to x already and you get 4.0
so if y=16, x should =4.0

Answer:
14.2%
Step-by-step explanation:
1. Find the new cost for Stock A:
2000x0.88=1760
2. Find the new cost for Stock B:
5720x0.85=4862
3. Find total sum of the original stocks:
2000+5720=7720
4. Find total sum of the new stocks:
1760+4862=6622
5. Find the decrease:
7720(1-x)=6622
Solve for x
x=14.2

Answer:
mean
Step-by-step explanation:
Normal distribution curves Is a distribution curve having different mean values with a standard deviations
the correct option: mean
A normal distribution curve is standardized as follows:
(a) The mean value of the unstandardized curve is made the origin, thus making the mean value, x, zero.
(b) The horizontal axis is scaled in standard deviations. This is done by letting z= x−x/ σ , where z is called the normal standard variate, x is the value of the variable, x is the mean value of the distribution and σ is the standard deviation of the distribution.
