Answer:
(1,5)
Step-by-step explanation:
2x-3(x+4)=-13 y=1+4

-x=-1/-1
x=1
Answer:
0.19706
Step-by-step explanation:
-Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
Hence,the probability that an employee makes between $70,000 and $80,000 is 0.19706
The 10^-4 means that the decimal point is 4 places to the left of where it is in 8.25 (if the exponent was positive the decimal point would be to the right). If you move the decimal point 4 places to the left you get an answer of 0.000825 which is 8.25 * 10^-4 in standard form.
Per year 7% for $2000 bond. It will be $140 per year.
Then per 6 months, it will be $70.
so, answer is B.
