3m² = 3 - 8m
0 = 3m² + 8m - 3
0 = (3m - 1 )(m + 3)
m = -3, 0.33
The ladder, the wall and the floor form together a triangle rectangle, where the ladder is the hypotenuse of the triangle and the floor and wall are the cathetus. We know from Pythagoreas theorem that the square of the hypotenuse is equal to the sum of the two cathetus squared added, so we can write an equation with the data we have:
hyp^2 = cath1^2 + cath2^2
<span>hyp^2 = wall^2 + floor^2
</span>so we have the hypotenuse value, the floor value and the unknown is the wall height:
(22)^2 = wall^2 + (7)^2
484 = wall^2 + 49
wall^2 = 484 - 49 = 435
wall = √435
wall = 20.9
therefore the ladder touches the wall 20.9 feet above the ground
36000 over 1 to get the fraction of 36000
Answer:
The lender or servicer must automatically terminate PMI when your mortgage balance reaches 78 percent of the original purchase price — in other words, when your loan-to-value (LTV) ratio drops to 78 percent.
Answer:
Step-by-step explanation:
a) Odd numbers if n then even numbers also n
Total prob = 1 gives 3c=1
c=1/3
b) X=1, if even and
0, if odd
Y =1, if x >3 and
=0 otherwise
xy can take values as 0 or 1
xy =1 if x even and y is greater than 3, or favorable outcomes are
4, 6.
xy= 1 if die shows 4 or 6
=0 if otherwise
Prob (xy) = 1/3, for xy =1 and
= 2/3 for xy =0
This is binomial since each trial is independent.
If 12 tosses are made then if we have binomial proba
with n =12 and p = 1/3 for success
