Answer:
x=6
Step-by-step explanation:12-8+3=7
(12-8)+3=4+3=7
So the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.
<u>Check: </u> <u>IT SAYS THAT N IS GREATER THAN 8 SO CHOOSE A NUMBER GREATER THAN 8 WHICH CAN BE 9.</u><u>
</u>
8+9n≥80
8+9*9≥80
8+81≥80
90≥80, so this makes sense.
The probability of students preferring pepsi over coke would be 0.0059.
<u>Explanation:</u>
Total number of students = 50
More than half of the students preferred Pepsi to coke.
Half of 50 would be 25
So, minimum of 26 students should prefer Pepsi to coke
Standardized value: ( Y - 17.5 ) / 3.373
P (Y >= 26) = P (Z >= (26-17.5) / 3.373)
= 0.0059
Therefore, the probability of students preferring pepsi over coke would be 0.0059.
