You've certainly tried hard to describe it in enough detail so that
it can be answered without seeing the diagram.  Sadly, it's not
enough. 

We still don't know what's tangent to what, where point 'C' is, or
how any of this relates to a circle.  You'll have to figure out some
way or us to see the diagram.

Assume the heights in a male population are normally distributed with mean 70.3 inches and standard deviation 4.1 inches. If a r
klemol [59]

Answer:

73.1 inches

Step-by-step explanation:

We solve for this using z score formula.

z-score is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean

σ is the population standard deviation.

x = unknown = randomly selected male's height

μ = 70.3 inches

σ = 4.1 inches

z = is not given but we are given its percentile which is 75

The z score for a 75th percentile = 0.674

Hence,

0.674 = x - 70.3/4.1

Cross Multiply

0.674 × 4.1 = x - 70.3

2.7634 = x - 70.3

x = 70.3 + 2.7634

x = 73.0634 inches

The height of the randomly selected male = 73.0634

Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches

F(x)=\sqrt{\frac{20 x}{x^2-49}}
Lyrx [107]

Answer:

Great use of desmos! But since one line doesn't touch the x- axis it would have to be +infinity. the other line does touch at (0,0) so the x would be 0. This is a question that you should ask your teacher about for sure.

Sorry I cant be more help!
