Answer:
Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
Hey there! There are approximately 252 inches in 7 yards! Take care!
Domain are all the x - values included in the graph.
In this case all the x - values are (listed from smallest to largest and excluding duplicates):
{-3, -2, 0, 1}
^^^This is also your domain
NOTE: There are several different ways to write domain. Let me know if this is the way you need it to be written in
Hope this helped!

Perpendicular lines have opposite reciprocal slopes.
y = 1/4x - 10 is our original equation.
If we flip the slope and change the sign, we get -4
The answer is -4
Answer:
a)
b)
c)
Step-by-step explanation:
For this case we know that the mean for the random variable of interest is and the variance so then the deviation would be
The z score is given by thsi formula:
Part a
We want this probability:
And if we find the z score we got:
And we can find this probability:
Part b
We want this probability:
And if we find the z score we got:
And we can find this probability:
Part c
We want this probability:
And if we find the z score we got:
And we can find this probability:
