To figure out this problem break it down into steps.
We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.
25 - 1 = 24.
Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.
Probability = 15/24 = 5/8.
For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.
5/8 • 5/8 = 25/64.
The probability of getting 2 cards that are greater than 10, are 25/64.
This is the solution.
(17 1/3) / 24 = x/1
cross multiply
24x = 52/3
x = 52/3 * 1/24
x = 52/72 = 13/18 inches per hr
Answer: has a maximum
the maximum is 11
Step-by-step explanation:
f(x)= -5x^2-10x+6
the function f(x)= ax^2+bx+c=0 has a<0 so the equation has a maximum
I know V has the coordonate x=-b/2a, and y=-(b^2-4ac)/4a
b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220
so -b/2a=-(-10)/-2*5=+10/-10=-1 and
-(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11
so V( -1, 11)
and the maximum is 11
10 - 3 - 6x - A
Answer: 7 - 6x - A
This is the simplest the original expression can get :)
