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]
Answer:
x =9
Step-by-step explanation:
We want the value when g(x) = 3
We want when the y = value is 3
When y = 3 the x value is 9
g(9) =3
Answer:
1 . 25 or 5/4 as a fraction
Step-by-step explanation: Hope this helps mark me branliest plssss;)
Slope intercept form is y=mx+b
first plug in m
y=-1/2X + b
now plug in the point (8,1) for the x and the y
1=-1/2(8) + b
now you need to solve for b
simplify
1=-4+ b
add 4
5=b
now that you know b
you can plug it into the equation along with the m
so the answer is
y=-1/2X + 5
