If the baby gained 7/16 of a pound in 1/2 a month, you need to multiply 7/16*2 to find how many pounds the baby will grow in one month. 

7/16*2

Cancel 2 and 16<span>.
</span><span>7/8

</span>Exact Form: 
<span>7/8</span> 

<span>Decimal Form: </span>
<span>0.875

The baby gained 7/8 or 0.875 pounds in 1 month</span>

What's the area of the shaded region?
satela [25.4K]
Do you remember how to find the area of a circle ?

Big Fat Hint:  The area of a circle is  (pi) x (its radius)² .

Can you find the area of the big circle ... the one with radius = 18 m ?
Do that.  The whole big circle, just as if there was nothing inside it, and
no shaded region.
I'll wait.


Now, can you find the area of the small circle ... the one with radius = 12 m ?
Do that.
I'll wait.

The area of the shaded region is just

         (the area of the big circle) minus (the area of the small circle) !


I got 180 pi or roughly 565.2 m².  I could be wrong.  You should check it.

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.
babunello [35]

The x-coordinate of the given endpoint will be "x = 4 \pm 2\sqrt{29}".

According to the question,

The end points are:

  • (x_1,y_1) = (4,-1)
  • (x_2, y_2) = (x,9)

Distance,

  • 6\sqrt{6}

As we know,

The distance formula,

→ Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

By substituting the values, we get

→         6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}

→          216= (x-4)^2+100

→   (x-4)^2 = 116

→       x-4 = \pm \sqrt{116}

→       x-4=\pm 2\sqrt{29}

→             x = 4 \pm 2\sqrt{29}                

Thus the above answer is right.

Suppose you have an experiment where you flip a coin three times. You then count the number of heads. a.)State the random variab
WITCHER [35]

Answer:

a) X=number of heads observed when flipped the coin 3 times

b) the probability distribution is

P(X=x) = 3/4 * (1/[(3-x)!*x!)])

or

P(X)=1/8 for x=0 and x=3 and P(X)=3/8 for x=1 and x=2

Step-by-step explanation:

the random variable will be X=number of heads observed when flipped the coin 3 times . Since the result from each flip is independent of the others , then X has a binomial probability distribution , such that

P(X=x)= n!/[(n-x)!*x!)*p^x * (1-p)^(n-x)

where

n= number of times the coin is flipped = 3

p= probability of getting heads in a flip of the coin = 1/2 (assuming that the coin is fair)

therefore

P(X=x)= 3!/[(3-x)!*x!)*(1/2)^(3-x) * (1/2)^x = 3!/[(3-x)!*x!) * (1/2)³ = 3/4 * (1/[(3-x)!*x!)])

P(X=x)= 3/4 * (1/[(3-x)!*x!)])   , for x=[0,1,2,3]

for x=0 and x=3 → P(X)=3/4 * (1/[3!*0!)]) = 1/8

for x=1 and x=2 → P(X)=3/4 * (1/[2!*1!)]) = 3/8

we can verify that is correct since the sum of all the probabilities from x=0 to x=3 is  1/8 +  3/8+ 3/8+ 1/8 = 1
