Engineers want to design seats in commercial aircraft so that they are wide enough to fit 9090​% of all males.​ (Accommodating 1
Molodets [167]

Answer:

Hip breadths less than or equal to 16.1 in. includes 90% of the males.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 14.5

Standard Deviation, σ = 1.2

We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.10.

P(X > x)  

P( X > x) = P( z > \displaystyle\frac{x - 14.5}{1.2})=0.10  

= 1 -P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.10  

=P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.90  

Calculation the value from standard normal z table, we have,  

P(z < 1.282) = 0.90

\displaystyle\frac{x - 14.5}{1.2} = 1.282\\x = 16.0384 \approx 16.1  

Hence, hip breadth of 16.1 in. separates the smallest 90​% from the largest 10%.

That is hip breaths greater than 16.1 in. lies in the larger 10%.

Answer:

d = 10 m

Step-by-step explanation:

Given that,

tLauren is 6 meters straight behind Alexa and  8 meters directly left of Danielle. We need to find the distance between Alexa and Danielle. It can be calculated using Pythagoras theorem such that,

d=\sqrt{8^2+6^2} \\\\d=10\ m

So, the distance between Alexa and Danielle is 10 m.
