Answer:
>3 means any number on the number line larger than 3, so the answer is yes
Answer:
selecting one item? If you mean each color:
40% chance for a red marble / 2/5 chance
60% chance for a blue marble / 3/5 chance
Step-by-step explanation:
Because there are 12 blue marbles and 8 red marbles, we would total them to see how many marbles there are in total. There are 20 in total, but to find the probability, if we put all 20 marbles in a bag (blue and red), and we picked a marble at random, there are 8 red marbles and 12 blue marble in that bag. The probability that I will choose red marbles is 8/20 (or 8 red marbles out of 20 total marbles), and for blue marbles, it would be 12/20 (or 12 blue marbles out of 20 total marbles). Simplify both expression to 2/5, and 3/5 respectively. Finally, if you need percentage, just multiply the denominator by 5 to get it to a hundred, and do the same to the numerator. This way you don't change the value of the expression.
D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
'of' in mathematics means multiplication
'is' in mathematics means equal
52% * x = 13
52/100 * x = 13
0.52x = 13
x = 13/0.52
x = 25
52% of 25 days is 13 days.
