Answer: \dfrac{1}{2}

Step-by-step explanation:

If we assume that the boys and girls are equally​ likely, so the probability of having a girl is equal to probability of having a boy = \dfrac{1}{2} .

Let B = Event of having a boy.

G= Event of having a girl.

Since both events are independent of each other . (Events that do not depends on each other.)

So irrespective of the four baby boy , the probability that the fifth child is a boy = \dfrac{1}{2}

Therefore , the probability of a couple having a baby boy when their fifth child is​ born, given that the first four children were all boys= \dfrac{1}{2}

Help. only questions 3 & 4 .

I'm doing 3

     For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

         On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

         And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

                Hope this helped!

What is 436/85 as a mixed number.?
ivann1987 [24]

Answer:

5  11/85

Step-by-step explanation:

First see how many times a whole number can be found.

436/85 = 5.1294

The denominator goes into the numerator 5 times.

Now we find a new numerator.

436 - (85 * 5) = 11 (this is the amount left over after we made 5 wholes.)

Now we see 5 11/85

It cannot be simplified further.

Jim and his dad are building a rectangular flower bed. They have a total of 35 feet of landscaping timber to use, and they want
Mama L [17]
The perimeter is 35.  If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change.  This means that perimeter will no longer be 35.  So in order to keep the perimeter as it is, if we change one dimension, we must also change the other. Let's solve for the length, using the formula to see how much the length changes from. p = 2l + 2w 35 = 2l + 2(15) 35 = 2l + 30 5 = 2l 2.5 = l  We must increase the length from 2.5 feet.  This is because decreasing one dimension will decrease the perimeter.  But if we increase the other dimension as well, it will restore the perimeter to where is was initially.
