Step-by-step explanation:
In the second step while opening the bracket, instead of 'a', there should be - 4a.
Slope = (-3 - r) / (2 - 5)
Slope = <span>(-3 - r) / -3 = 4/3
-(-3 - r) = 4
3 + r = 4
r = 4 - 3
r = 1 option b.</span>
Answer:
the answer is c.44 .....yw

Answer:
If our random variable of interest for this case is X="the number of teenagers between 12-17 with smartphone" we can model the variable with this distribution:

And the mean for this case would be:

And the standard deviation would be given by:
