Answer:
0.73
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of black cards = 26
Number of face cards = 12
Probability of drawing either a black or face card
Probability = required outcome / Total possible outcomes
P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)
= 26/52 + 12 /52
= 0.5 + 0.2307692
= 0.73
Answer:

Step-by-step explanation:




Hence


Hopefully you get what I meant!!
3.3 gallons
Explanation:
8/60 is .13 so .13x25= 3.3
The equation for height as a function of time can be written as
.. h(t) = -16t^2 +110t +2
.. = -16(t^2 -55/8t) +2
.. = -16(t^2 -55/8t +(55/16)^2) +2 +55^2/16 . . . . . complete the square
.. = -16(t -55/16)^2 +191 1/16 . . . . . . . . . . . . . . . . . . vertex form
The maximum height the ball will reach is 191 1/16 feet.
