Tems11 [23]

Answer:

<em>He should pack </em><em>9 loaves</em><em> of bread for a 12 day hiking trip if he eats the same amount of bread each day.</em>

Step-by-step explanation:

Hint- This can be solved by Unitary method.

Sam used 6 loaves of elf bread on an 8 day hiking trip.

or in an 8 days trip he used 6 loaves of bread,

so in 1 day he would use \dfrac{6}{8} loaves of bread,

so in a trip of 12 days he would use \dfrac{6}{8}\times 12=9 loaves of bread.

Therefore, he should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.

Using Bayes' theorem we can solve for the probability

S|B=\frac{B|S*S}{B|S*S+B|S'*S'}=\frac{.55*.6}{.55*.6+.2*.4}=0.80487804878

In parallelogram ABCD , BE=7x−2 and ED=x2−10 .
Stells [14]

I'm assuming that the diagonals intersect at E. Since diagonals of a parallelogram bisect each other, BE=ED.

  • 7x-2=x²-10
  • x²-7x-8=0
  • (x-8)(x+1)=0
  • x = -1, 8

As distance must be positive, we reject the negative case, so x=8.

Thus, BE=ED=54.
