Y - 9 = 15x - 75
y = 15x - 75 + 9
y = 15x - 66 y = mx + c, slope = m
m = slope = 15
There are 9 marbles in the bag. We pick 2 without replacement and get a probability of 1/6.
Each draw of a marble has a probability associated with it. Multiplying these gives 1/6 so let us assume the probabilities are (1/3) and (1/2).
In order for the first draw to have a probability of 1/3 we need to draw a color that has (1/3)(9)=3 marbles. So let's say there are 3 red marbles. The P(a red marble is drawn) = 1/3.
Now that a marble has been drawn there are 8 marbles left. In order for the second draw to have a probability of 1/2 we must draw a color that has (1/2)(8) = 4 marbles. So let's say there are 4 blue marbles out of the 8.
Since there are 9 marbles to start and we have 3 red marbles and 4 blue marbles, the remaining 2 marbles must be a different color. Let us say they are green.
The problem is: There are 3 red marbles, 4 blue marbles and 2 green marbles in a jar. A marble is picked at random, it's color is noted and the marble is not replaced. A second marble is drawn at random and its color noted. What is the probability that the first marble is red and the second blue?
Answer:
Step-by-step explanation:
14.Since the most common denominator is 40 lets multiply all the denominators to equal all to 40
Evita:24/40
Jack:25/40
Keisha:30/40
Sinjo:20/40
Therefore Keisha drank the most bottles
15. The most common denominator for 5/8 and 2/3 is 24 lets have both denominators equal to 24
5/8 -> 15/24
2/3-> 16/24
Therefore flour is the greater amount
16.Multiply the denominators equal to 6 since thats the least common denominator
1/2->3/6 | 2/3->4/6
Therefore peanuts is the greater ingredient amount
17.If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value. Therefore, equivalent fractions can be created by multiplying (or dividing) the numerator and denominator by the same number.
18.We can compare fractions with unlike denominators by finding the least common denominator and making equivalent fractions. When the denominators are the same, the number with the larger numerator is the larger fraction.
Answer:
1/2
Step-by-step explanation:
Since half of them chose to play dress-up, the probability of randomly selecting a child that chose to play dress-up would also be 1/2.
(hope this helps :P)
