Answer:
The estimate of the proportion of oil tankers that had spills is 65/211 = 0.308.
Step-by-step explanation:
Proportion of oil tankers that had spills.
Number of tankers with spills divided by the total number of tankers.
In this question:
211 tankers
146 did not have spills, so 211 - 146 = 65 had
Proportion:
![p = \frac{65}{211} = 0.308](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B65%7D%7B211%7D%20%3D%200.308)
The estimate of the proportion of oil tankers that had spills is 65/211 = 0.308.
Answer:
The team is measuring at 364 ft below the surface
Step-by-step explanation:
Here, we want to get the depth at which the pressure was measured at
to get this, we will have to use the equation that relates the pressure to the depth
From the question, we have this as;
P = 13 + 8/13(d)
From the question, P is 237
Substituting this into the equation, we have
237 = 13 + 8/13(d)
237-13 = 8/13(d)
224 = 8/13(d)
8d = 13 * 224
d = (13 * 224)/8
d = 364 ft
