The minimum number of socks that she needs to get such that a pair is always formed is 5.

<h3></h3><h3>How many socks must she get to be ensured of having a pair?</h3>

We know that she has:

  • 10 white socks.
  • 10 black socks
  • 10 brown socks
  • 10 blue socks.

First, we need to compute the maximum number of socks she needs to take in such a case that no pair is formed.

That will be 4, and represents the case where:

1 white sock, 1 black sock, 1 brown sock, and 1 blue sock are drawn. At that point, no pairs are formed.

Now, if she draws another sock, a pair will always be formed.

From this, we conclude that if she draws 5 socks, always at least one pair will be formed.

5=27
N=5

Explanation=there’s a difference between each number of 5

Eg:12-7=5
17-12=5
22-17=5
So that means 22+5=27 and n=5 since it is the number difference

Need help with a math question
Darya [45]

Answer:

Z =7

Step-by-step explanation:

The middle segment theorem of a triangle says that: A middle segment connecting two sides of a triangle is parallel to the third side and is half its length.

In this case, the middle segment connecting two sides of a triangle is Z.

This means that

Z = 0.5(14)

Finally we have that:

Z =7

The length of the middle segment is 7 units

A sphere has a surface area of about 999 square millimeters. What is the radius, in millimeters, of the sphere
motikmotik

Given that, a sphere has a surface area of about 999 square millimeters.

Formula to find the surface area of sphere is,

S= 4πr² Where r = radius of the sphere and S= surface area.

Given S= 999 square millimeters.

So, we can write:

4πr² = 999

4 * 3.14 * r² = 999 Since, π = 3.14

12.56 *r² = 999

r^2=\frac{999}{12.56} Divide each sides by 12.56.

r² = 79.53821656

r = √79.53821656 Taking square root to each sides of equation.

r = 8.918420071

So, r = 8.918 Rounded to nearest thousandth.

So, radius of the sphere is 8.918 millimeters.

Hope this helps you!
