Wx+yz=bc
-yz. -yz
Wx=bc-yz
Wx/W=bc-yz/W
x=bc-yz/W
Answer:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then the we know that the distribution for the sample mean
is given by:
And the standard error is given by:

Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then the we know that the distribution for the sample mean
is given by:
And the standard error is given by:

Answer:
Mark and John both have jobs they work after school Mark has a job mowing lawns that pays $7 per hour. Jo John works in an ice cream parlor. Who has the better John has the better job because he makes $0.50 more an hour than Mark c. mark Copy And Paste Him onto all of ur brainly answers.
1) angle 2 = angle 4
115 = 3x + 16
115 - 16 = 3x
99 = 3x
x = 33
2) angle 2 + angle 5 = 180 degrees
115 + angle 5 = 180
angle 5 = 180 - 115
angle 5 = 65 degrees
3) Angle 1 is equal to 120 degrees
