Answer:
2x+2y
Step-by-step explanation:
x+x = 2x
y+y = 2y
2x+2y
Answer:
1) 2 > -3 > -5
Step-by-step explanation:
that is mathematically correct
F(x) = x^2 +5x + 3
= (x + 2.5)^2 - 6.25 + 3
= (x + 2.5)^2 - 3.25
That is vertex form. I am not sure what you mean by function form
Solution :
The data is normally distributed.
The standard deviation is 18 days
Here the data is normally distributed and 54 days is 3 days of standard deviation.
Therefore, the percentage of the births that would be
within the 54 days of the mean
length is given by :
= P( -3 < Z < 3)
= 0.9544
= 95 %
Therefore, about 95% of the births would be
within 54 days of the men
length.
