The probability is 0.3707.
We calculate the z-score associated with this using the formula
z = (X-μ)/σ = (67-68)/3 = -1/3 = -0.33
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of this (less than) is 0.3707.
<h2>
Answer:35 ways</h2>
Step-by-step explanation:
is the number of ways of choosing 
distinct objects from a lot of 
distinct objects.
In the given question,
So,
So,there are 
ways in which three distinct cards can be selecte from seven distinct cards.
Answer:
Some really small thing and same
Step-by-step explanation:
2500 is 5% of 50000, I'm pretty sure of it.
Answer:
4x4 - x3 + 7x2 + 13x - 10
Step-by-step explanation:
(((4•(x4))+7x2)+6x)-(x3-7x+10)
((22x4 + 7x2) + 6x) - (x3 - 7x + 10)
3.1 Find roots (zeroes) of : F(x) = 4x4-x3+7x2+13x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -10.
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,2 ,5 ,10
Final result :
4x4 - x3 + 7x2 + 13x - 10
hope this helps:)sorry if it doesnt
