Answer:
Step-by-step explanation:
Given that a survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.2 in.
Let X be the random variable representing women heights.
P(58<X<80)
Z for 58 = -2.454
Z for 80 = 7.545
P(-2.454<Z<7.545) = 0.4945+0.5=0.9945
Answer:
Step-by-step explanation:
2x-3= 12
+3 +3
2x = 15
/2 /2
x= 7.5
You can use the factored form of the quadratic polynomial and then find the simplified sum.
The numerator of the simplified sum of the given expression is
<h3>How to factorize a quadratic polynomial with single variable?</h3>
Quadratic polynomial with single variables are expressible in the form
where x is the variable and a,b,c are constants.
Its factored form is
<h3>Using the above method and finding the simplified form of the given expression</h3>
The given expression is
Factorizing using the aforesaid method, as we have got
a = 1, b = 3, c = 2,
thus, we have
Thus, the given sum is
Thus, the numerator of the simplified sum is
