Vinvika [58]

Answer:

1:200

5.6 cm^2 : y (as actual area)

y = 200 mutifly 5.6 cm^2

y= 1120 cm^2

We know 1m =100cm

so, 1m^2 =100cm x 100 cm = 1000cm^2

y= 1120 m^2/ 100x100

Suppose you have three nickels in a jar, where the first has Heads on both sides, the second has Tails on both sides, and the th
Cerrena [4.2K]

Answer:

1/3

Step-by-step explanation:

Let A be the event that you grab the fair coin and B be the event that you toss a tail.

P(A) is the probability that you grab the fair coin, which is 1/3

P(B) is the probability that you toss a tail, which is 1/2

P(B|A) is the probability that you toss a tail, given that you grab a fair coin, which is 1/2

P(A|B) is the probability that you grab the fair coin, given that you toss a tail, which we are looking for.

Using Bayes probability theorem we have:

P(A|B) = \frac{P(B|A)P(A)}{P(B)} = \frac{(1/2)*(1/3)}{1/2} = 1/3

Mult. 536 by 410.  Hold the 0 for now and mult your final answer by 10.

Mult 536 by 41:  The first partial product is (536)(1) = 536.
                           The second is (536)(4) = 2144.

Align these partial products as follows:

                          536
                      2144  
                      ----------
                      219760 (we held that final 0, remember?)
