What is the probability that the first two people share a birthday?
AlekseyPX
Hello!

Assuming that these people were born in a fair year (no leap year, etc.) there is a 1/365 chance of one birthday. Each person has this 1/365 chance, so if we are referring to two people, we get a 1/133225 chance, which is about 0.27%.

I hope this helps!

The area of rectangular is 46 square inches.if the length is 4 times the width . Then find the dimensions of the rectangular
dimulka [17.4K]

Answer:

the rectangle's width is approximately 3.39 inches

and the length is approximately 13.56 inches.

Step-by-step explanation:

Recall that the area of a rectangle is Length times Width

If we name the length "L" and the width "W", we have:

L * W = 46

Also: "the length is 4 times the width" can be written in math form as:

L = 4 * W

and now we can replace the length L by 4 * W in the formula for the area:

L\,*\,W = 46\\(4\,W) \,W = 46\\4\,W^2=46\\W^2=\frac{46}{4} =11.5\\W=\sqrt{11.5} \\W\approx 3.39

and now we find the value of L:

L=4\.(3.39) = 13.56

Therefore, the rectangle's width is approximately 3.39 inches

and the length is approximately 13.56 inches.

I think you are doing limits so this is what I did
and that's how I factored using the box method because it's easier to track distribution.
