Answer:
Option 3 is right
z37 is between 2 and 3 standard deviations of the mean.
Step-by-step explanation:
Let X be a random variable which represents the mean number of miles that the employees in a department live from work
X is normal (N(29,3.6)
WE have to find Z score for X
Z =
=2.22
i.e. 37 is 2.22 std deviations from the mean.
In other words, z37 is between 2 and 3 standard deviations of the mean.
Hi! the answer is 2+[8x1296] because you break the 28 and the 1296 stays the same

Answer:
- (x -3)^2 +(y -5)^2 = 9
- x^2 +y^2 -6x -10y +25 = 0
Step-by-step explanation:
The standard form equation for a circle of radius r and center (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
For radius 3 and center (3, 5), this is ...
(x -3)^2 +(y -5)^2 = 9 . . . . standard form equation
Expanding this and subtracting the constant on the right gives ...
x^2 -6x +9 +y^2 -10y +25 -9 = 0
x^2 +y^2 -6x -10y +25 = 0 . . . . general form equation
The relationship is that both of them are next to each other and there both and seperate places and value
The time taken to get to work from home with a speed of 30mph will be 40 minutes, 40mph in 30 minutes, and 50mph in 24 minutes.
<h3>What is velocity?</h3>
Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity can be given as;
Average velocity = total distance / total time taken
Units of velocity are given by ⇒ meter/second
As per the given,
Time = distance/speed
Distance = 20 miles
With a speed of 30 mph
Time = 20/30 = 2/3 hour or 40 minutes
With a speed of 40 mph
Time = 20/40 = 1/2 hour or 30 minutes
With a speed of 50 mph
Time = 20/50 = 2/5 hour or 24 minutes
Hence "The time taken to get to work from home with a speed of 30mph will be 40 minutes, 40mph in 30 minutes, and 50mph in 24 minutes".
