Answer:

Yellow.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.

In this question:

6 + 5 + 4 + 10 = 25 total marbles.

The experimental probabilities are:

6/25 probability it is red.

5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.

4/25 probability it is blue.

10/25 = 2/5 probability it is green.

Solve 2(x-2) = 3(x+2)-8
IgorC [24]

Answer:

x = -2

Step-by-step explanation:

2(x-2) = 3(x+2)-8

Multiply the 2 and 3 out to the numbers in the parentheses. Don't multiply the 3 out to the -8 because it is outside of the parentheses.

2x-4 = 3x+6-8

Combine the 6 and -8

2x-4 = 3x-2

Subtract 2x from both sides

-4 = x-2

Add 2 to both sides

-2=x

Solve the equation. Show work for partial credit.
Natali5045456 [20]

Answer:

x = \frac{8}{5}

Step-by-step explanation:

Given

\frac{5}{x} + \frac{3}{x} = 5 ← combine terms on left side

\frac{8}{x} = 5 ( multiply both sides by x )

8 = 5x ( divide both sides by 5 )

\frac{8}{5} = x

Given the function f(x) = x2 and k = -3, which of the following represents a vertical shift? (2 points)
lubasha [3.4K]
Answer:
f(x) + k

Explanation:
Vertical shift is represented by adding/subtracting a constant from the original given equation.
If the constant added is +ve, this means that the curve is vertically shifted upwards
If the constant added is -ve, this means that the curve is vertically shifted downwards.

Now, for the given, we have the original function f(x) and the constant k, therefore, to shift the graph vertically, the new function would be f(x)+k
We have:
f(x) = x² and k = -3
This means that the new function would be:
x² - 3
Since the constant is -ve, we can conclude that the curve is shifted vertically downwards by 3 units

Hope this helps :)
