Answers

Answer 1

Answer:

True, a radar gun records a car's speed and a sign displays the text "speeding" or "not speeding."

The text displayed is a random variable because it is determined by the car's speed, which is a random event. The radar gun measures the speed of the car, and based on that measurement, the sign will display either "speeding" or "not speeding." Since the car's speed is a random event, the text displayed on the sign is also a random variable.

A skydiver is falling 176 feet per second. How many feet per minute is he falling

Answers

The correct answer here is that if the skydiver is falling 176 feet persecond, he is falling 10560 feet per minute. This can be worked outquite easily, by considering that if there are 60 seconds in a minute,we then need to work out the proportion of 176 feet/1 sec = x/60 sec.You then need to multiply 60 by 176 to get 10560, which is your answer.

PLZ HELP! MATH >__<What is the lateral area of the rectangular prism with a base length of 14 m, a base width of 9 m, and a height of 6 m?
A. 264 m2
B. 276 m2
C. 528 m2
D. 756 m2

Answers

Lateral area = surface area not including the bases.

To find this area we just need to add up the area of all of those sides.

The 2 bases are the same area and defined by the length and width.

That leaves the 2 sides defined by length and height,
plus the 2 defined by width and height.

Of course, to find the area of a rectangle, we just multiply together its two dimensions.
length × height = 14 × 6 = 84
width × height = 9 × 6 = 54

2 × 84 + 2 × 54 = 276 m²

My answer would be 276m2
