Answer: 2 3/4 > 2.68 is correct (only)

Step-by-step explanation: 2 3/4 = 2.75, and 2.75 is greater than 2.68

The rest are incorrect. 7.895 * 10^2 (100) = 789.5, and 5.43 * 10^3 (1000) = 5430. So 789.5 > 5430 is false.

Sqrt(63) = 7.93, and 7.93 > 8.11 is false.

Absolute values ( | | ) mean that no matter if it is negative or positive, it will become positive (unless the negative sign is outside the absolute value). 1.5 > 3.2 is false, and even without the absolute value, -1.5 is still less than 3.2

An urn contains 10 balls numbered from 1 to 10. Carlo and Eric each draw a ball at the same time. Given that Carlo's number was

Rama09 [41]

Answer:

1/9

Step-by-step explanation:

There are 10 x 9 ways to choose two balls from the urn. Order does not matter, since Carlo must have the larger ball. So there are 10 choose 2 total ways to choose the balls. If Carlos has the 6, Eric can only have balls 1-5, so the answer is 5/45, or 1/9.

Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded?

Phantasy [73]

First we need to express y in this inequality:
-2y > -4x + 20
-y > -2x + 10
y < 2x - 10

The line isn't solid because the "less" sign doesn't include equal in it.
Because the sign is "less than" the shaded part is Below the line.

Merging these 2 conclusion we get the answer:
below the dashed line.
