Answer:
220 cents, $2.20
Step-by-step explanation:
Count the amount of QUARTERS there are.
7 quarters.
The next coin in the photo is a dime.
4 dimes.
The next coin in the photo is a penny.
5 pennies.
Quarters are worth 25 cents, dimes are worth 10 cents, and pennies are worth 1 cent.
25(7) + 4(10) + 5(1) = v (the total value)
25 * 7 = 175 cents
4 * 10 = 40 cents
5 * 1 = 5 cents
175 + 40 + 5 = v
175 + 40 = 215 cents
215 + 5 = 220 cents
The value of all of those coins is 220 cents, or $2.20.
Answer:
positive
Step-by-step explanation:
if not then it should be no correlation
From the graph, we can see that the graph crosses the x-axis at the point (1.5, 0) the graph also passes through point (1, 1) and the graph crosses the y-axis at the point (0, 3).
Therefore, points (1.5, 0), (1, 1) and (0, 3) are some of the solutions of the graph.
Answer:
The expected volume of the box is 364 cubic inches.
Step-by-step explanation:
Since the die is fair, then P(X=k) = 1/6 for any k in {1,2,3,4,5,6}. Let Y represent the volume of the box in cubic inches. For how the box is formed, Y = X²*24. Thus, the value of Y depends directly on the value of X, and we have
- (When X = 1) Y = 1²*24 = 24, with probability 1/6 (the same than P(X=1)
- (When X = 2) Y = 2²*24 = 96, with probability 1/6 (the same than P(X=2)
- (When X = 3) Y = 3²*24 = 216, with probability 1/6 (the same than P(X=3)
- (When X = 4) Y = 4²*24 = 384, with probability 1/6 (the same than P(X=4)
- (When X = 5) Y = 5²*24 = 600, with probability 1/6 (the same than P(X=5)
- (When X = 6) Y = 6²*24 = 864, with probability 1/6 (the same than P(X=6)
As a consequence, the expected volume of the box in cubic inches is
E(Y) = 1/6 * 24 + 1/6*96 + 1/6*216+ 1/6*384+ 1/6*600+1/6*864 = 364
