Since it's asking you to write a problem about a sharing division "situation", I'm assuming the picture above it is part of #4 so you could use that as a reference as well.

You could do 2 divided by 5 which is left with a remainder. So it could be like, "Jack has 5 cookies and wants to share with his friends, he wants to give each of his two friends 2 cookies each".. Something like that and you go ahead and solve it. The final answer will be the solution to your word problem. I hope this helped

Answer:

$Pr = 6.67\%$

Step-by-step explanation:

Given

$n = 10$ i.e. 10 people

Required

Probability of being next to each other

First, we calculate the total possible arrangements (without any restriction)

$Total = n!$

$Total = 10!$

If the three are to be next to each other,

First, we arrange the three

$r_1 = 3!$

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)

The arrangement is:

$r_2 =8!$

So, the total arrangement, when they have to be next to one another is:

$r = r_1 * r_2$

$r = 3! * 8!$

The probability is:

$Pr = \frac{r}{n}$

$Pr = \frac{3! * 8!}{10!}$

Expand

$Pr = \frac{3*2*1 * 8!}{10*9*8!}$

$Pr = \frac{3*2*1}{10*9}$

$Pr = \frac{6}{90}$

$Pr = 0.0667$

Express as percentage

$Pr = 0.0667 * 100\%$

$Pr = 6.67\%$

Hasan is painting a spherical model of a human cell for his science class. He uses 100π square inches of paint (in one coat) to

Answer:

10 in

Step-by-step explanation:

So we want to consider the surface area of this sphere.

The formula for surface area of a sphere is $A=4 \pi r^2$ .

So we have that the surface area is $100 \pi$ .

So I'm going to replace $A$ in $A=4 \pi r^2$ with $100 \pi$ .

$100\pi=4\pi r^2$

Now our main objective here is to solve for $r$ :

Divide both sides by $4 \pi$ :

$\frac{100\pi}{4 \pi}=\frac{4\pi r^2}{4 \pi}$

This gets us $r^2$ by itself:

$25=r^2$

What number squared gives you 25? If you don't know, just take the square root of both sides giving you:

$\sqrt{25}=r$

Now you can just put $\sqrt{25}$ in your calculator. You should get 5.

5 is the radius

The diameter is twice the radius.

So 2(5) is 10, so the diameter is 10 in.
