The answer is C because theoretically it should have a 50% of landing heads but instead it lands heads 56% of the time. Thus this is 6% higher than 50%. It's not D because there is not specified detail of how the person got this data so you can assume that the person did a fair survey/data collection.

Roy is correct. When you multiply fractions, you multiply the numerator of one fraction and the other numerator of the other fraction, and vice versa for denominator.
7 x 3 = 21 (Numerators)

3 x 8 = 32 (Denominators)

Arturiano [62]

Answer: 94.24 feet.


Step-by-step explanation:

1. To solve this exercise you must apply the formula for calculate the perimeter of a circle, which is shown below:

P=2r\pi

Where r is the radius of the circle.

2. You can calculate the radius of the circle by dividing the diameter by 2, as following:

r=\frac{30ft}{2}\\r=15ft

3. Substitute this value into the formula. Then, you obtain that the result is:

P=(2)(15ft)(\pi)\\P=94.24ft

Y varies directly with x and y = 12 when x =5 what is the value of y when x = 8
torisob [31]
Y and x are directly proportional, as stated by hypothesis. Let's use the rule of three to find y when x = 8.

x=5 --> y=12
x=8 --> y=?

? = (8*12)/5 = 96/5 = 19.2

So y directly varies with x, and y=12 when x = 5, then y=19.2 when x=8.

Hope this Helps! :D
