Answer:
The following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Step-by-step explanation:
Given
Computing by substituting x = 1, and y = -2
1) x+y = 1+(-2) = -1
2) x - y = 1 - (-2) = 1+2 = 3
3) x times y = xy = (1)(-2) = -2
4) x divided by y = x/y = 1/-2 = -2
It is clear from the above calculations that when we put x = 1, and y=-2 then the expressions (x+y), (x times y), and (x divided by y) become negative.
Therefore, the following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Answer:37.5% approximately 38%
Step-by-step explanation:
Probability formula= Number of possible outcome/ Total favorable outcome
Number of possible outcome=15
Number of total outcome =40
15/40×100=37.5 approx. 38%
Answer:
ok
Step-by-step explanation:
The probability is 1/1024.
Each tetrahedron has a 1/4 chance of landing on 3, since there are 4 sides and only one of them is marked 3.
Each tetrahedron roll is independent, since no roll is affected by another.
This means we multiply the probabilities:
1/4(1/4)(1/4)(1/4)(1/4) = 1/1024
Answer:
72 × 3 = 216m
216 m is the combined length
