When it comes to probability, the answer is always expressed as part of a whole. With that being said, your answer for this problem can be a ratio, fraction or in percentage. Probability is the study of finding the chances or odds of an event happening with the use of statistics. You are already given the statistics of baby girls and baby boys. Note that you are asked to find the probability of the baby being a girl. So, the part here includes the 248, while the whole is 248+13 = 261. Therefore, the probability is 248/261 or 0.95 or 95%. That means that the likelihood of having a girl baby using this technique is very high.

Find the distance between the points (0,-8) and (3,2). Round your answer to the nearest hundredth.
Reil [10]

Answer:

10.44

Step-by-step explanation:

First plot each of the points on to a graph at their respective positions.

Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)

You can then use the pythagorean theorem a^{2} +b^{2} = c^{2}.

Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 3^{2} + 10^{2} = c^{2}

Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = c^{2} which in turn is 109 = c^{2}

Then take the square root of 109 to remove the square from the c to get c = 10.44

A right cylinder ice cream cone has 600 cubic centimeters of ice cream, what is the radius of the cone of the height is 15 centi
choli [55]
The formula for volume is V=Bh where  B is the area of the base. 
plug in what they have given you:
600=B(15) you can divide both sides by 15

40=B    We know that a cylinder's base is a circle so we can use the area f                           formula for a circle to solve for the radius.
40 = pi(r)^2   divide both sides by pi to get the r^2 alone
40/pi=r^2     square root both sides to get rid of the square
you should get
r=3.5 approximately
