No. 7.8 is not equivalent to 9.

If you rounded to the nearest whole number, yes, the number that you'd get would be 9 but if you were to look at the two values, 7.8 and 9, then no, these two are not equivalent due to the fact that 9 is 1.2 values higher than 7.8

The total amount owed after 6 months will be found using the formula:
FV=P(1+r/100*n)^n
P=principle=$10000
r=rate=18%
n=terms=0.5

FV=10000(1+18/2*100)^0.5
FV=$10,440.30651
Thus the amount owed will be $10440.30651

If S is countable and nonempty, prove their exist a surjection g: N --> S

aleksley [76]

Answer with Step-by-step explanation:

We are given S be any set which is countable and nonempty.

We have to prove that their exist a surjection g:N $\rightarrow S$

Surjection: It is also called onto function .When cardinality of domain set is greater than or equal to cardinality of range set then the function is onto

Cardinality of natural numbers set = $\chi_0$ ( Aleph naught)

There are two cases

1.S is finite nonempty set

2.S is countably infinite set

1.When S is finite set and nonempty set

Then cardinality of set S is any constant number which is less than the cardinality of set of natura number

Therefore, their exist a surjection from N to S.

2.When S is countably infinite set and cardinality with aleph naught

Then cardinality of set S is equal to cardinality of set of natural .Therefore, their exist a surjection from N to S.

Hence, proved

the daily temperatures last week were 68,70,73,75,76,76 and 82 degrees. what fraction of the temperatures were above 75 degress?

Annette [7]

3/7. There are 7 temperatures, so the denominator is 7. However, only 3 of them were above 75, so the numerator is 3.
