Step-by-step explanation:
24x^2_54x_15=0
(12X +3 ) ( 2X _5 ) . = O
12x +3 =0
X= - 1/4
or
2x _ 5=0
X = 5/ 2
It is equivalent too 5.3 and 5.30
Answer:
a) true
Step-by-step explanation:
There are 13 heart-suit cards in a 52 card deck.
Since cards are returned to the deck after each pick, all of the 15 events are independent and have the same likelihood of occurring. Therefore, this experiment follows a binomial distribution with the following properties:
Number of events (n) = 15
Probability of success (Picking a heart) = 13/52 = 1/4
Probability of failure (Not picking a heart) = 39/52 = 3/4
In conclusion, the statement provided is true.
Answer:
d is your Answer .............
The generic equation of the line is given by:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = (3 - (- 4)) / (- 2 - (- 1))
m = (3 + 4) / (- 2 + 1)
m = (7) / (- 1)
m = -7
We choose an ordered pair:
(xo, yo) = (-1, -4)
Substituting values:
y - (- 4) = - 7 (x - (- 1))
Rewriting:
y + 4 = -7 (x + 1)
y = -7x-7-4
y = -7x-11
Answer:
y = -7x-11
