Answer:

B. 1.8 miles

Step-by-step explanation:

We have been given that Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool.

Since Keith turns at a 90 degree, so the given lengths will form a right triangle with each leg equal to 3 miles.

The direct distance between house and pool would be hypotenuse of right triangle.

h^2=3^3+3^2

h^2=9+9

h^2=18

Take square root of both sides:

h=\sqrt{18}

h=4.24264068

h\approx 4.2

The distance covered by the 90 degree angle would be 3+3=6 miles.

\text{Distance saved by directly traveling to pool}=6-4.2

\text{Distance saved by directly traveling to pool}=1.8

Therefore, Keith would have saved 1.8 miles, if he had ridden directly to the pool.

gavmur [86]

Answer

given,

mean of women  (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

using z-table

P(x>66)= 1 - 0.8944

P(x>66)=0.1056[/tex]for men[tex]P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

using z-table

P(x>66)= 1 - 0.0548

P(x>66)=0.9452
