The range is 12 because range means is finding the distance of the numbers which is 0-12 so our answer is 12.
The scale has two sides:
The Left Hand Side (LHS) and the Right Hand Side (RHS).
Let the weight of the sphere be represented as s
Let the weight of the cube be represented as c
Let the LHS have the 5 spheres and 1 cube, represented as = (5s + 1c)
Let the RHS have the 2 spheres and 3 cubes, represented as = (2s + 3c)
If the cube c, weighs 150 gram, c = 150g
Since the scale is balanced, therefore the weights on the LHS would be equal to the weights on the RHS.
Therefore: (5s + 1c) = (2s + 3c), c = 150.
(5s + 1*150) = (2s + 3*150)
(5s + 150) = (2s + 450) collect like terms.
5s - 2s = 450 - 150
3s = 300 Divide both sides by 3
s = 300/3
s = 100
Therefore the sphere weighs 100 gram each.
I'm thinking its "D"

Hey there! Welcome to Brainly!
Let's see how many marbles we have in total.
12+11+17+5=45
We want to find the probability of selecting a marble that is not blue. Let's see how many marbles aren't blue.
12+11+5=28
We have this probability out of 48.
28/48
We simplify, giving us 7/12 or about 58.33%.
I hope this helps!
The formula is
A=p (1+r/k)^kt
A future value?
P present value 874
R interest rate 0.032
K compounded quarterly 4
T time 7 years
A=874×(1+0.032÷4)^(4×7)=1,092.46
