Answer:
25
Step-by-step explanation:
X² = 7² + 24²
X² = 49 + 576
X² = 625
X = 25
Answer:
2/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
First Line:
0, 1//7, 2/7, 3/7, 4/7, 5/7, 6/7, 1, 8/7, 9/7, 10/7
Second Line:
-1/3, 0, 1/3, 1/2, 1, 4/3
Third Line:
0, 1/3, 2/3, 1, 4/3, 5/3, 2
Start off by combining like terms on the LHS (the terms with x in them).
So we get

Replacing this result with what we had before on the LHS, we get

⇒Solve for x (divide both sides

)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by

⇒

⇒

***This is a proper fraction
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.
