It's the same angle. The equation, then, is 5y+1=51. Subtract one from both sides, so now you've got 5y=50. Divide each side by 5 and you've got y=10.
Answer:
5x 2 19x 4
9 6x 2 19x 2
factor 5x 2 19x 4
4x 2 19x 5 0
factor 6x 2 19x 7
6x 2 19x 36Factor 5x^2-19x+12. For a polynomial of the form , rewrite the middle term as a sum of two terms whose product is and whose sum is . Tap for more steps... Factor out of . Rewrite as plus. Apply the distributive property. Factor out the greatest common factor from each group. Tap for more steps...
Step-by-step explanation:
2y + 4 + 5y + 8=
7y + 4 + 8=
7y + 12=
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:
