Answer:
the answer is one over eight
the formula says required outcome divided by sample space
the sample space here is it because we have three coins and the Three coins have two faces each so it becomes 2 x 2 * 2 that is 8 and that is the total sample space we are supposed to get the probability of getting 3 tails and for each coin you have 1/2 x 1/2 x 1/2 and that is 1/8 as your final answer and do probability of getting three tails
Answer:
7x - 4
Step-by-step explanation:
2x + 4 + 5x - 8
7x + 4 - 8
7x - 4
Answer:
QBO=12 degrees
Step-by-step explanation:
angle QAO=angle OAS so:
2x+6=4x-12
reducing:
2x=18
x=9
substituting x into QBO=3x-15 then:
angle QBO=3(9)-15=12 degrees
17 because 100 - 55 = 45 14/45%= 31 31 times 55%= 17
