ZX is √b²+a²
Step-by-step explanation:
From the diagram you notice that length WX is a and length WZ is b.ZX is the diagonal length formed by triangle ZWX.Apply the Pythagorean relationship here the sum of squares of the two sides equals the square of the diagonal.Hence;
ZW²+ WX²=ZX²
b²+a²=ZX²
√b²+a²=ZX

Answer:
Probability that the randomly selected two students both have no loans to pay = 0.09
Step-by-step explanation:
Probability that a student has a loan to pay is 0.7, hence probability that a student has no loan to pay is
1-0.7 = 0.3
Probability that the randomly selected two students both have no loans to pay = 0.3 × 0.3 = 0.09
First if x equals 1 then you would do 3x1 which would get you 3, then add the 3 plus 3 to get 6
Answer:
in the numerator
in the denominator
Step-by-step explanation:
First fraction simplifies to:
Dividing my a fraction is the same as multiplying by the reciprocal, so the second fraction simplifies to:
So the equation becomes:
The (x+3) and (x+5) terms cancel out, so what your left with is
Expanding this term you get the answer:
in the numerator
in the denominator
