Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4

sukhopar [10]

Answer:

An adult male Komodo dragon is $10\frac12$ feet.

Therefore the male is $1\frac34$ feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is $1\frac34$ feet long.

It's mother is $8\frac34$ feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6× $1\frac34$ ) feet

$=6\times \frac74$ feet

$=\frac61\times \frac74$ feet

= $\frac {21}2$ feet.

$=10\frac12$ feet.

$\therefore 10\frac 12- 8\frac34$

$=\frac{21}{2}-\frac{35}4$

$=\frac{21\times 2-35\times 1}{4}$

$=\frac{42-35}{4}$

$=\frac74$

$=1\frac34$

Therefore the male is $1\frac34$ feet longer than the mother.

Poker. 26 red, 26 black. Take one every time, you can choose to guess whether it’s red. You have only one chance. If you are rig

xenn [34]

Answer: 339/8788= 0.039

Step-by-step explanation:

Let black card be represented with B and the red card be represented with r. Therefore, P(B,r) is the expected value.

Hence, we say, (b,r) is not equal to (0,0) for the first state, we then, have a probability of B/r+B(the probability of drawing out a black card and loosing a point.

Also, (B-1,r) state with the probability of r/r+B(which is the probability of drawing out a red card and gaining a point).

The expected value is therefore;

B/r+B(-1+(B-1,r) + r/r+B(1+P(B,r-1))

Therefore, if we have negative, then;

P(B,r)=0,B/r+B(-1,r)) + r/r+B(1+P(B,r-1))...

P(0,0)=0; P(26,26) = 339/8788

=.039

Note: we say that the expectation at the start if we draw red,gaining +1 and if we draw black and then draw two reds you end +1. That is; 1/26 × 2/26 × 1/26 = 1+ 338/8788

= 339/8788.

Inverse operation to squaring a number

Sliva [168]

Answer:

The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:
