Answer:
The probability will be 0.3085 or 0
Step-by-step explanation:
Given:
True mean=12.5
Sample mean =12.6
Standard deviation=0.2
Samples=100
To Find:
Probability that exceeds 12.6 ounces.
Solution:
Calculate the Z-score for given means and standard deviation.
So
Z-score= (true mean -sample mean)/standard deviation.
Z-score=(12.5 -12.6)/0.2
=-0.1/0.2
=-0.5
Now Using Z-table
P(X≥-0.5)=p(Z≥-0.5)=0.3085
Hence Probability that sample mean weight exceeds will be 0.3085
OR
By using Normal distribution with sampling ,it will be as follows
Z=(X-u)/[Standard deviation/Sqrt(No of samples)]
Z=(12.6-12.5)/(0.2/Sqrt(100)
Z=0.1/0.2/10
Z=5
So P(X≥12.6 )=P(Z≥5)=1
Pr(Z≥5)=1-1=0.
(Refer the attachment )
Hence Probability of getting ounces greater than 12.6 is '0'.
The sampling is of 0.02 size hence graphically it looks likely.
as shown in attachment.
Answer:
(-infinity,+infinity)
Step-by-step explanation:
Domain refers to the x-axis. So if we look from left to right along the x-axis we could conclude that the function will go infinitley from negative infinite to positive infinity.
Answer:
Let p be the the elevation of a passage in meters
An inequality that represents elevations below -8 meters is
p less than -8 meters. Mathematically,
<h3><u>p<-8</u> is the right answer.</h3>
Hello.
So, you should already know that to find the inverse of a function you switch x and y and solve.
For f(x) = x² + 3, it's domain is all real numbers, and the range is y ≥ 3.
The inverse of f(x), it is
, and the equation is
= ±√(x - 3). It's domain is x ≥ 3, and the range is all real numbers.
There are many unique characteristics about inverses, like the values of x and y are switched, it's reflected on the line y = x, and the domain and range is switched.
So your final answer is
c.
f(x) domain: all real numbers, range: y ≥
3
domain: x ≥
3, domain: all real numbers.
Hopefully it makes sense! :)
