You're a teacher in a 7th grade math class and you want to create an experiment for your class with red, yellow, and purple marbels in a bag you want the theoretical probability of drawing a red marble to be 1/2, the theoretical of drawing a yellow to be 1/4, and the theoretical probabitity of drawing a purple to also be 1/4. if you want a total of 80 marbles in the bag

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

69.64%

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
