Step-by-step explanation:

=2x+3x8

=add

=5x8

=x=5=8/2

=x=5/4 is your answer

where p0 is the atmospheric pressure at sea level and k is a constant. If the atmospheric pressure is 14.7 lb/in.2 at sea level

balu736 [363]

Answer:

The value of pressure at an altitude of 10000 ft = 10 $\frac{lb}{in^{2} }$

Step-by-step explanation:

Given data

Atmospheric pressure $P_{0}$ = 14.7 $\frac{lb}{in^{2} }$

Pressure at 4000 ft = 12.6 $\frac{lb}{in^{2} }$

If temperature is constant then the atmospheric pressure is varies with the altitude according to law

P (h) = $P_{0}$ $e^{- kh}$ ------ (1)

where k= constant & h = height

12.6 = 14.7 $e^{- 4000k}$

0.857 = $e^{- 4000k}$

㏑ 0.857 = - 4000 k

-0.154 = - 4000 k

k = 3.85 × $10^{-5}$

Thus the atmospheric pressure at an altitude of 10,000 ft is

$P_{10000} =$ 14.7 × $e^{- kh}$ ----- (2)

Product of k & h is

k h = 3.85 × $10^{-5}$ × 10000

k h = 0.385

Put his value of k h = 0.385 in equation (2) we get

$P_{10000} =$ 14.7 × $e^{-0.385 }$

$P_{10000} =$ 10 $\frac{lb}{in^{2} }$

This is the value of pressure at an altitude of 10000 ft.

The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mea

Archy [21]

Answer:

Step-by-step explanation:

Given data:

$\mu = 473$

standard deviation is $\sigma= 28$

As distribution is normal in shape and values are symmetrical

The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean

so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval

$= \mu + 2\times \sigma$

$= 473 + 2\times 28 = 529$

almost 0.15% of students spent more amount is 529
