Answer:
The value of pressure at an altitude of 10000 ft = 10 
Step-by-step explanation:
Given data
Atmospheric pressure
= 14.7 
Pressure at 4000 ft = 12.6 
If temperature is constant then the atmospheric pressure is varies with the altitude according to law
P (h) =
------ (1)
where k= constant & h = height
12.6 = 14.7 
0.857 = 
㏑ 0.857 = - 4000 k
-0.154 = - 4000 k
k = 3.85 × 
Thus the atmospheric pressure at an altitude of 10,000 ft is
14.7 ×
----- (2)
Product of k & h is
k h = 3.85 ×
× 10000
k h = 0.385
Put his value of k h = 0.385 in equation (2) we get
14.7 × 
10 
This is the value of pressure at an altitude of 10000 ft.

Answer: 0.0386
Step-by-step explanation:
Given: The probability hat the frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked : p= 0.30
Sample size : n = 12
Let x = Number of contaminated chickens
Here , two outcomes for any chicken (either contaminated or not) , so it follows binomial distribution.
Binomial probability formula:
The probability that the consumer will have more than 6 contaminated chickens :-

<em> (simplified)</em>
<em />
Hence, the required probability = 0.0386
7x+4 is the correct awnser(i think)
tan( 31 ) = x / 39
0.600860619 = x / 39
x = 0.600860619 × 39
x = 23.433564141

Round to the nearest tenth :
x = 23.4
Round to the nearest hundredth :
x = 23.43
