Answer:
(a): T=56
(b): V=3
Step-by-step explanation:
(a) T=8V, V=7
T=8(7)
T=56
(b)T=8V, T=24
24=8V
(Divide 8 on each side)
V=3
Idk if you wrote it incorrectly. but im just going to avoid the first 5× soooo x= -1
Answer:
![\frac{6}{7} yd^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D%20yd%5E%7B2%7D)
Step-by-step explanation:
Area is the width (6/7 yd) multiplied by the height (1 yd).
6/7 x 1 = 6/7 ![yd^{2}](https://tex.z-dn.net/?f=yd%5E%7B2%7D)

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
