Answer: d. s ≥ 23


Step-by-step explanation:

Let s be the side of the square.

We know that the perimeter of a square =4s

Let f(s)=4s

If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

4s\geq 92

Divide both sides by 4, we get

s\geq\frac{92}{4}\\\Rightarrow\ s\geq23

Thus, d. is the right answer. The reasonable domain of f(s) is s\geq23

Luden [163]
For the selection to be 10, there has to be at least 3 girls. So there's a 1/4 chance of 3 girls picked, 1/4 4 girls, 1/4 5 girls and 1/4 6 girls. Because the sum of people has to be 10, if 4 girls are picked, to make 10 people there is a 1/1 chance of 6 boys. 1/4 * 1/1 = 1/4. So 1/4 chance of 4 girls and 6 boys
