You have to post a picture of the actually histogram we can’t see it
Y=-4 is one of your answers
Answer:
1 pink marble
Step-by-step explanation:
If Jamie selected 10 times the pink marble in a total of 420 tries, we can assume that the proportion of pink marble in the total number of marbles is:
10 / 420 = 1/42
So to predict a good number of pink marbles in the total 40 marbles, we just need to multiply the 40 marbles by the proportion found above:
pink marble = 40 * (1/42) = 0.9524
As this number needs to be a whole number, a good assumption is that there is 1 pink marble in the 40 marbles.
Answer:
3.6 and 1.2
Or
-3.6 and -1.2
Step-by-step explanation:
Let x and y be the two numbers
xy = 4.32
x/y = 3
x = 3y
3y² = 4.32
y² = 1.44
y = +/- 1.2
x = +/- 3.6
