First, identify the formula you will use.
sum of all scores / number of scores = 225.
(192 + 214 + 250 + x) / 4 = 225
192 + 214 + 250 + x = 900
x = 900 - 656
x = 244

Step-by-step explanation:
Answer:
68 %
Step-by-step explanation:
(a) Using the 68-95-99.7% rule, between what two lengths do the most typical 68% of all pregnancies fall?
95%? 99.7%?
The middle 68% of all pregnancies last between 266-16 and 266+16 days, 250 to 282. The middle 95% of all
pregnancies last between 266-2*16 and 266+2*16 days, 234 to 298 (for future reference, note that this “rule” is
rounded somewhat compared to the charts). The middle 99.7% of all pregnancies last between 266-3*16 and
266+3*16 days, 218 to 314.
The equation for this polynomial graphed will be P(x) = a(x + 2)(x + 1)(x – 3)³.
<h3>What is polynomial?</h3>
A polynomial expression is an algebraic expression with variables and coefficients.
The graph of the polynomial is given below.
From the graph, the roots of the polynomial will be -2, -1, and 3.
Then the factor of the polynomial will be
(x + 2), (x + 1), and (x – 3)
Then the polynomial will be
P(x) = a(x + 2)(x + 1)(x – 3)³
