Answer:
25 pounds
Step-by-step explanation:
Let us assume that initially, 1 pound of whole chicken costs x.
So, initially 20 pounds of whole chicken costs 20x.
Now, the price is reduced by 20%.
That means that 1 pound of whole chicken now costs ![x[1-\frac{20}{100} ]=0.8x](https://tex.z-dn.net/?f=x%5B1-%5Cfrac%7B20%7D%7B100%7D%20%5D%3D0.8x)
Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.
Hence, with a 20x amount of money, we can now purchase 
pounds of the whole chicken.
Solve for w:
p = (1.2 w)/h^2
(1.2 w)/h^2 = (6 w)/(5 h^2):
p = (6 w)/(5 h^2)
p = (6 w)/(5 h^2) is equivalent to (6 w)/(5 h^2) = p:
(6 w)/(5 h^2) = p
Multiply both sides by (5 h^2)/6:
Answer: w = (5 h^2 p)/6
Find the critical value or test statistic.
Find P(z > 2.25) using a normal distribution table
P(z > 2.25) = 0.0122
Answer:
C. approximately 99.99%
Step-by-step explanation:
The distribution bell shape is a normal distribution, with mean 120 mmHg and standard deviation 12 mmHg.
The rank between 96 mmHg and 144 mmHg is wider than the rank between mean plus, minus 3 standard deviation (102 mmHg up to 138 mmHg), and this rank is approximately 99.7 %.Therefore 99.99 % includes more closely values in the rank 96 up to 144 mmHg
