Answer:

The probability is 1/3, or in percent form, 33.3%.

Step-by-step explanation:

First, add up all the marbles. 3 plus 2 plus 1 equals 6 total marbles.

There are 2 yellow marbles out of 6 total marbles. Make it a fraction: 2/6.

Simplify the fraction by dividing by 2, to get 1/3, which is 33.3%.

jenny went to mall with $120 in her wallet. spent $25.65 on a shirt $4.58 on a snack . how much money does she left
V125BC [204]
She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack
25.65 and 4.58 are the numbers that you have to add together then subtract from 120.
so 25.65+4.58=30.28
So then you subtract 30.28 from 120 and get 89.72
She has $89.72 left over
Hope I helped :)

A piggy bank contains nickels and dimes. There are 160 total coins valuing $10.50. Think about a system of equations that can be
Elodia [21]
x + y = 160 \\ 0.05x + 0.1y = 10.50
First, Substitute x + y = 160 into equation
x = 160 - y
0.05(160 - y) + 0.1y = 10.50 \\ 8 - 0.05y + 0.1y = 10.50 \\ 0.05y = 2.50 \\ y = 50
Substitute that into
x + 50 = 160 \\ x = 110

The answer is 110.

Hope this helps. - M

What is the equation of the midline of the sinusoidal function?
WITCHER [35]
Answer: y = 0
Note: of course you don't need to type in the "y=" part as its already taken care of

----------------------------------------------------------

The highest point is when y = 5
The lowest point is when y = -5
Find the midpoint of those y values. Add them up: 5 + (-5) = 0
Then divide that result by 2: 0/2 = 0

The midpoint of 5 and -5 is 0. So the midline is y = 0
This is the center horizontal line that runs through the middle of the sinusoidal curve
The vertical distance from the midline to either the peak or valley is the same (in this case, 5) which is known as the amplitude
