There are eight marbles in a bag. Four marbles are blue (B), two marbles are red (R) and two marbles are green (G) Steve takes a marble at random from the bag. What is the probability that Steve will take a blue marble.
Answers
Answer:
1/2 or 50%
Step-by-step explanation:
Blue= 4, Red= 2, Green= 2
Total marbles= 8
P(B)= 4/8= 1/2 or 50%
Answer:
1/2
Step-by-step explanation:
There are 8 marbles in total and 4 are blue, so 4/8 are blue. Then simplify 4/8 and you will get 1/2.

y=2x-9
Step-by-step explanation:
The slope is 2 and the y-intercept is -9
Answer:
y = 2x - 9
Step-by-step explanation:
Y2 - Y1/X2 - X1
7 - 1/8 - 5

= 2
y = 2x + b
1 = 2(5) + b
1 = 10 + b
-9 = b

The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.
However, I'll solve for the vertex of the given function.
Given
Vertex, V is of the form:
Where
and
Solving for h:
So:
Solving for k
Substitute 2.5 for x in
Hence:
The vertex is
The correct vertex for the function is (2.5, 122.375).
The given function is .
To find the vertex of a quadratic function in the form , we can use the formula x = -b / (2a) to find the x-coordinate of the vertex.
In this case, the coefficient of is -9.5, the coefficient of x is 47.5, and there is no constant term.
Using the formula, we can find the x-coordinate of the vertex:
Now, substitute this x-coordinate back into the original function to find the y-coordinate:
Therefore, the correct vertex for the function is (2.5, 122.375).
Micah's error might be related to incorrectly calculating the x-coordinate of the vertex or substituting the wrong value back into the function.
