The distribution of height of adult american women is approximately normal with a mean of 65.5 inches and a standard deviation o

Blizzard [7]

Answer:

2.275%

Step-by-step explanation:

We start by calculating the z-score

Mathematically;

z-score = (x-mean)SD

here, x = 70.5

mean = 65.5

SD = 2.5

Substituting these values;

z = (70.5-65.5)/2.5

= 5/2.5 = 2

So we want to calculate the probability that;

P( z> 2)

We check the standard normal distribution table for this

That will be

0.02275

In percentage, this is 2.275 %

Napoleon Crossing the Alps

timama [110]

It took him 2.6 hours to reach the top

Data;

Uphill = 6km
Downhill = 4km
Total time taken = 8 hours

<h3>Speed</h3>

Let us calculate the speed during uphill and downhill

Since the time it took them to descend is twice the time it took them to ascend,

Let x represent the time taken to ascend

$x + 2x = 8 hours\\3x = 8\\x = \frac{8}{3} \\x = 2.6 hours$

From the calculation above, it took him 2.6 hours to reach the top.

0v0 h e l p? <br><br> 3r/4=1/8 (solve for r)

agasfer [191]

Answer:

r = 1/6

Step-by-step explanation:

$\dfrac{3}{4}r=\dfrac{1}{8}\\\\\\$

Multiply both sides by 4

$4*\dfrac{3}{4}r=4*\dfrac{1}{8}\\\\3r = \dfrac{1}{2}$

Divide both sides by 3

$\dfrac{3}{3}r=\dfrac{1}{2*3}\\\\r = \dfrac{1}{6}$
