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:
3^12
Step-by-step explanation:
When the whole numbers are the same, add the exponents
The volume is 1012 cm³.
The volume of a right prism is found by multiplying the area of the base and the height. First we need to convert the height to centimeters.
1 dm = 10 cm
2.3 dm = 2.3(10) = 23 cm
Now we have 44(23) = 1012 cm³
Answer:
x = -5
Step-by-step explanation:
Note that x does not change. Hence, this line is a vertical one, and its slope is undefined. The line is defined by the equation x = -5.
