Your friend rolls a number cube 500 times. How many times do you think your friend will roll an odd number? Explain your reasoning.

Answers

Answer 1
Answer: 250, because of probability. Half of the number are full of odd numbers. Half are full of even. The probability will be 1/2. So 1/2 of 500 is 250. So your answer is 250 times.

a diver descends from an elevation of 6 feet below sea level to an elevation of 98 feet below sea level in 4 equal intervals. What was the diver's change in elevation in each interval? Explain your answer.

Answers

The diver's change in elevation in each interval is, 23

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A diver descends from an elevation of 6 feet below sea level to an elevation of 98 feet below sea level in 4 equal intervals.

Hence, The diver's change in elevation in each interval is,

⇒ (98 - 6) / 4

⇒ 92 / 4

⇒ 23

Thus, The diver's change in elevation in each interval is, 23

98-6=92. This represents the amount of space he has to dive.
92/4=23. This represents your equal intervals. 


So the answer is that the diver dove in equal intervals of 23 ft.

The surface area of a cube is 24 cm squared. What would the surface are of the prism be if each dimension were quadrupled?

Answers

cubeSA=6 squares
SA=6s^2
SA=24
24=6s^2
divide 6
4=s^2
2=s

quadrupled means times 4
2*4=8
8=new side

SA=6(8^2)
SA=6(64)
new SA=384 cm^2
