Answer:
Proportion of buildings in the city that have fire code violations: 10%
Uncertainty 0.3 = 30%
Step-by-step explanation:
This situation complies with a binomial model where p is the probability of finding a building having fire code violations and q=1-p
Since in random sample of 40 buildings chosen for inspection 4 of them are found to have fire code violations, the proportion is 4/40 = 0.1 or 10% and p=0.1 as well.
<em>In a</em> <em>binomial model the standard deviation s is:
</em>
<em>
</em>
<em>where n is the sample size</em>. So
and the uncertainty is the standard error SE
If A=((1/7)^-5 ) 3 , so A= (1/<span>7)^-15 (power property)
the answer is </span><span>b. (1/7 ) ^-15 </span>
Answer:
1.85%
Step-by-step explanation:
→ Find the difference between the actual and predicted
5.5 - 5.4 = 0.1
→ Divide answer by 5.4
0.1 ÷ 5.4 = 0.01851851851
→ Multiply answer by 100
0.01851851851 × 100 = 1.85%

Answer:
5/4
Step-by-step explanation:
The relationship between the sec and csc functions is ...
csc(A) = sec(A)/√(sec²(A) -1)
For the given value of sec(A), this is ...
csc(A) = (5/3)/√((5/3)² -1) = (5/3)/√(16/9) = (5/3)/(4/3)
csc(A) = 5/4
