Answer:

P(King) = 4/52 = 1/13

Step-by-step explanation:

As we know there are 52 cards in total from 2 to 10, and King, Queen, Jack, and Ace, with each of them are equal in numbers which is 4.

Total Number of Kings in the Deck of Cards  = 4

P(King) = Number of Kings/Total Number of Cards

Given (x)=-x²+2x,determine<br> F'(x) using first principle
mote1985 [20]
Hello,
which principle?

f(x)=-x²+2x
==>f'(x)= -2x+2

You mean maybe this

\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}


f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x

\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}=\lim_{h \to 0}\frac{-2hx-h^2+2h}{h}=\lim_{h \to 0}\frac{-2x-h+2}{1}=-2x+2

What is the position of F on the number line below? write your answer as a fraction or mixed number​
nadya68 [22]

Answer:

\frac{3}{4}

Step-by-step explanation:

There are 4 steps to complete to go from 0 to 1. Hence each step is:

1 out of 4, or simply  \frac{1}{4}

F is located at the 3rd mark, which will be  \frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}

Hence, F is located at  \frac{3}{4}
