Answer:
The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%
Step-by-step explanation:
First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .
Answer:
this just helped me so much
Step-by-step explanation:
4/3 ÷ 5/3
4/3 × 3/5 use this rule; a ÷ b/c = a × c/b
4 × 3/ 3 × 5
12/15
4/15 simplify. or decimal form; 0.8
hope this helps, God bless!
Answer:
x > 2
y ≥ 2
x + y ≤ 8
Step-by-step explanation:
Here, we want to write a system of equations according to the given variables
More than means, greater than
since x is the variable we want to use;
x > 2
At least 2 hours means greater than or equal to 2
That is mathematically represented as;
y ≥ 2
At most means less than or equal to
So;
x + y ≤ 8
