Answer:
possible?? but I think that there is a typo, and that there would not be a bias
Step-by-step explanation:
can we assume that there are no typos in the question
he threw BUTTONS in the air, and look at buttons that landed with the BOTTOMS facing up ??? in that case the weight might bias the orientation of the landing... I think that you have a typo and it just says that he collected 14 BUTTONS, in that case given that they are "IDENTICAL" we most likely can assume that there would be no bias (size color, texture are all the same)
X is 1/4
2/3 X 1/4 = 1/6 make all have the same bottom number to make it easier
8/12 x 3/12 = 2/12
Answer:
≈ 660.5 in²
Step-by-step explanation:
The surface area (A) of a sphere is calculated using the formula
A = 4πr² ← r is the radius
Given diameter = 14. 5 then radius = 7.25, thus
A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²
Answer:
B) x=0
Step-by-step explanation:
x +20+ 10x= 9x +20
1st step: simplify the left side by combining like terms
10x+x=11x
2nd) 11x+ 20= 9x +20
Next, you subtract 11 and 9 which is equal to 2.
2x+20=20
Now, the 20 cancels out the other twenty so your left with 2x which is not an answer, therefore the only other number is 0 to be possible.
Check: 0+20+0=20 (first expression)
0x9=0 0+20= 20 (2nd expression)
20 = 20 so this is CORRECT!!!!!!!!
