Answer: 
Step-by-step explanation:
Distribute 1/4
add 5/2
Subtract 2x
Multiply by the negative reciprocal of -7/4 which is basically inverting the fraction -4/7
1 1/3 All you do is 4-3 + 2/3-1/3= 1 1/3
58 stamps is the number she gets each week. So if she went for one week, 58*1=58. 58*2=116 and so on. Because we don't know the exact number of weeks, we say 58w or 58*w because you multiply however many number of weeks she collects.
Answer:
Probability of getting tail (Number times a coins flip = 4 times) = 2
Probability of getting tail (Number times a coins flip = 4 times) = 5
Step-by-step explanation:
A . Number times a coins flip = 4 times
B . Number times a coins flip = 10 times
Computation:
Probability of getting tail = 1/2
Probability of getting tail (Number times a coins flip = 4 times) = 1/2(4)
Probability of getting tail (Number times a coins flip = 4 times) = 2
Probability of getting tail (Number times a coins flip = 4 times) = 1/2(10)
Probability of getting tail (Number times a coins flip = 4 times) = 5
