Yes.The second factor is the difference of 2 squares,
so the second factor alone becomes
(x² - 4) = (x + 2) (x - 2)
Answer: 36
Step-by-step explanation:
I'm not sure if this is 100% right this question was kinda messing with my brain , but if it's like asking how much she had in the 4 games all you had to do was add 9+9+9+9 or to make it easier you can just multiply 9 times 4 but I hope this is right.
Answer: 0.0000842890
Step-by-step explanation:
Given that :
Number of cards in a deck = 52
Number of hearts in a deck = 13
Probability of being dealt 6 hearts :
Probability = (required outcome / Total possible outcomes)
Required outcome = choosing 6 hearts from a possible 13
13C6:
Recall : nCr = (n! / (n-r)!r!)
13C6 = 13! / (13-6)!6!
13C6 = 13! / 7!6!
13C6 = (13*12*11*10*9*8)/(6*5*4*3*2*1)
13C6 = 1235520 / 730
13C6 = 1716
Total possible outcomes :
52C6 = 52! / (52-6)!6!
52C6 = 52! / 46!6!
52C6 = (52*51*50*49*48*47)/(6*5*4*3*2*1)
52C6 = 14658134400 / 720
52C6 = 20358520
Hence,
P(6 hearts) = 1716 / 20358520
P(6 hearts) = 0.0000842890
Answer:
If there are 12 white horses in 5 a herd of 52 horses, there will be 40 black horses if there aren't any other color horses.
The ratio will be 40 : 12
To simplify, it will be 10 : 3
Lines are parallel if they have the same slope. In order to write a new equation parallel to the one we are given, we have to know the slope of the line we are given. Solve it for y:
so
.
That means that the slope of the given line is -2/5. We will now use the point we were given and fill in the slope-intercept form of a line with the x coordinate of -1 and the y coordinate of 0:
so
and
.
Now that we have the slope and the y-intercept (the b value we just solved for), we can write the new equation:
.
There you go!
