Answer: The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample 
= 31.2 pounds .
Step-by-step explanation:
The weights of spawning Chinook salmon in the Columbia river are normally distributed.
Given : The mean weight from your sample is 31.2 pounds with a standard deviation of 4.4 pounds.
The point estimate for the mean 
weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample i.e. is 31.2 pounds because the best point estimate for population mean is the sample mean. [in normal distribution]

Step-by-step explanation:
Hello,
y = ax + b where a is the slope ! so here the slope is 6
Answer:
24 feet cubed
Step-by-step explanation:
When comparing the volume formula for a cone and the volume formula for a cylinder, a cone is 1/3 of a cylinder. Therefore, divide 72 by 3 to get the volume of a cone with the same base and height. It would not be 24 pi feet cubed because 72 feet cubed is already multiplied by the pi.
Hello! Looking at the numbers, you can see that the population of a country goes up by 1 million people each year. You could also say that it goes up by 2 million every 2 years. At this rate, the population in 2003 was 40 million. This is because 1997-2003 are 6 years apart. Do 1 million * 6 to get 6 million and add that to 34 million from 1997 to get 40 million in 2003.
