Probability of selecting 2 orange marbles
The total number of marbles is:
The probability that the first selection is orange is:
Because it is a selection without replacement, the number of orange marbles and the total number of marbles would decrease by 1, respectively.
So, the probability that the selection is orange is:
The required probability is:
Answer:
$100
Step-by-step explanation:
If $25 is increased by 300% it does increase by
So, the new amount will be $ (25 +75)
= 100 $
Answer:
Step-by-step explanation:
If 65% equals 147
Then to maintain 70% there is a need for 5% more
<u>Which equals</u>
Explanation:
First, add 3 both sides of an equation.
Then, simplify.
*The answer must be have a positive sign.*
Hope this helps!
Thank you!
Have a great day!
Answer:
This is the same as writing y < (-1/2)x+3
==============================================================
Explanation:
The dashed boundary line goes through (0,3) and (4,1)
Apply the slope formula for those two points
m = (y2-y1)/(x2-x1)
m = (1-3)/(4-0)
m = -2/4
m = -1/2
The slope of the dashed line is -1/2. The y intercept is 3. So we go from y = mx+b to y = (-1/2)x+3 to represent the equation of the dashed line. This is the same as writing
We shade below the dashed line to represent the inequality . Points in the shaded region are solutions to the inequality. One example point is (0,0).
Note that we don't have "or equal to" as part of the inequality sign because we are not including points on the boundary. A solid line, rather than a dashed line, would include points on the boundary.
