Mexico won the mexican american war
Step-by-step explanation:
P(A) = 0.47
P(B) = 0.53
P(A|B) = 0.57
a. Probability that at least one stock will rise is equal to P(A u B)
= P(A) + p(B) - P(A n B)
= (O.47+0.53)-(0.53*0.57)
= 1-0.3021
= 0.6979
b. Events A and B are not mutually exclusive. This is because P(AnB)≠0
P(AnB) = p(B).P(A|B)
= 0.53x0.57
= 0.3021 and this value is not equal to 0
c. No, events A and B are not independent. This is because P(A|B) ≠ P(A)
Since we have
p(A) as 0.47
P(A|B) as 0.53
False: although the size increases to its ratio, it is not considered similar
Hey there,
Ok so we need to put this into slope-intercept form so we can find the slope eaisly, (y=mx+b)
If we move x to the right side we are left with,
2y=-x-3
Next we divide by 2 to free up the y,
y=-1/2x-3/2, this is now in y=mx+b form. Making the slope -1/2
Hope this helped!
Since 50% are grade 6 and 0.3 from 5th grade these equal 8/10 so the fraction of participants from grade 7 would be 2/10
