A.You have to multiply the Original price(96) by todays discount(1/2)
96×(1/2)=48
Then to find the price 5 days from now you multiply the Original price(96) by the discount 5 days from now(2/3) but this time you subtract what you get from the original price 96×(2/3)=64
96-64=32 or the price of the coat 5 days from now
B. To find how much she would save subtract todays price(48) by the price 5 days from now(32)
48-32=16 She would save 16 dollars
Answer:
a) YES. Repeating decimal
b) YES. Repeating decimal
c) NO. Decimal neither terminates nor repeats
d) YES. Terminating decimal
Step-by-step explanation:
Any rational number can be written as a fraction, that is, a division of integers.
a) The number
has a repetitive period of 54. It can be expressed as a fraction because its decimal are repeating forever
b) The number 0.16666... (expressed as a repeating 6) can also be converted to a fraction because it's a repeating decimal
c) The number 0.5473... cannot be expressed as a fraction because the ellipsis (...) means the decimals continue with no limit and no pattern can be found (no repetitive decimal)
d) The number 0.378 can be easily expressed as a fraction because it has a finite number of decimals (no ellipsis) or a terminating decimal
X= a+b+c+bx/a(x-b) but I’m not completely sure
Answer:
Step-by-step explanation:
Given that in our industry on average a firm paid out record year end bonuses of $125,500 per employee for 2008. We would like to take a sample of employees at our firm to see whether the mean year end bonus is different from the reported mean of $125,500 for the population.
1. Sample Mean =
118000
2. Population Mean = 125500
3. Population Standard Deviation = 30000
4. Sample size = 40
5. Alpha Error = 5%
6. Confidence Coefficient = 95%
7. Calculate Test Statistic = Mean difference /s td error = -1.581
8. Rejection Region Critical Value = If Z statistic is below -1.96 or above 1.96
Answer:true,false,true,&true
Step-by-step explanation:You can compare irrational numbers using rational approximation. Square roots can not be compared and ordered by underneath the radical symbol.You can compare the value of rational and irrational numbers.And true the closer together the numbers being compared, the more decimal places you need to use.
