Answer:
(3,-4)
Step-by-step explanation:
Answer:
m = - 7.5
Step-by-step explanation:
Given
9 + m = 1.5 ( subtract 9 from both sides )
m = - 7.5
parallelogram , opposite sides are equal
so
PR = QS
and
PQ = RS
4x - 1 = 3x + 7
x = 8
PQ = 4(8) - 1 = 32 -1 = 31
Given P = 74 cm
74 - 2(31) = 12
PR = QS = 12/2 = 6
Answer
QS = 6 cm
Answer: 15 / 56
Step-by-step explanation:
Number of red checkers = 3
Number of black checkers = 5
Total number of checkers = 8
P(black, then red) = 5/8 × 3/7 = 15/56
We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.
