Answer:

22.5 miles per hour (rounded answer)

Step-by-step explanation:

This is a fraction equal to

18 miles ÷ 0.8 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.8

18 miles ÷ 0.8

0.8 hours ÷ 0.8

22.5 miles

1 hour

22.5 miles

hour

= 22.5 miles per hour

TEA [102]

Answer:

The correct answer will be "0.3043".

Step-by-step explanation:

The given values are:

$\mu = 15$

$n=41$

$\sigma^2=25$

then,

$\sigma=5$

If researchers know representative sample n > 30 and default deviation those who use z-test

∴ $P(x>15.4)$

⇒ $1-P(x$

⇒ $1-P(\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }$

⇒ $1-P(Z$

⇒ $1-0.695762$

⇒ $0.3043$
