It could. If you turn it into an experiment. Let's say you take 100 students from each grade, and you ask them if they exercise. And then you wanna create a graph. And find out out of those students how many of them exercise and how many of them do not. Then turn it into a percent.

I hope this helps. If you have any further questions on this or any other questions just ask. I am here to help you, as needed.

not really because some kids at the school might exercise more than other kids, so it can't be really a statistical question.

hope i helped:)

Erik drives 19.2 miles in 16 minutes.
Katen [24]

Answer:

Erik's average speed exceeds the speed limit by 6.91 miles per hour.

Step-by-step explanation:

Let suppose that Erik travels at constant speed. Hence, the speed (v), measured in miles per hour, is determined by following equation of motion:

v = \frac{s}{t} (1)

Where:

s - Distance, measured in miles.

t - Time, measured in hours.

Please notice that a hour equals 60 minutes. If we know that s = 19.2\,mi and t = 0.267\,h, then the speed of Erik is:

v = \frac{19.2\,mi}{0.267\,h}

v = 71.910\,\frac{mi}{h}

Which is 6.91 miles per hour above the speed limit.

If a 45 45 90 triangle has the hypothenuse of 10 what would the legs x and y be
melamori03 [73]

Answer:

Step-by-step explanation:

When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.

10/ sqrt(2) = 7.1 is the rounded answer.

to double check your work just multiply 7.1 by the square root of 2 and you'll get <em>close</em> to 10. (because the answer is rounded and not exact.)

The perimeter of a rectangle is 50 centimeters. If the width of the rectangle is 9 centimeters
nordsb [41]

Answer:

Length = 17 cm

Width = 8 cm

Step-by-step explanation:

Let the length be x cm

Therefore, Width = (x - 9) cm

Perimeter of rectangle = 2(l +w)

50 = 2[x + (x - 9)]

50/2 = 2x - 9

25 = 2x - 9

25+ 9 = 2x

2x = 34

x = 34/2

x = 17 cm

x - 9 = 17 - 9 = 8 cm

Therefore,

Length = 17 cm

Width = 8 cm

Thus, the dimensions of the rectangle are 17 cm and 8 cm.
