Answer:
The percentage of the bank's customers carry daily balances between $700 and $1,000 is 65.7%.
The minimum daily balance on which it should be willing to pay interest is $1,198.
Step-by-step explanation:
We have a normal distribution with mean = $800 and standard deviation = $150.
a) We can calculate this value with the standard normal distribution, calculating the z-value for $700 and $1,000.

The percentage of the bank's customers carry daily balances between $700 and $1,000 is 65.7%.
b) We must calculate from what amount only 6% of the accounts remain.
This is done by solving:

This happens for a z-value of z=2.652.
This corresponds to a amount of $1,198.

The minimum daily balance on which it should be willing to pay interest is $1,198.

Answer:
x<4 and x>1
Step-by-step explanation:
1) 3x-4<8
Add 4 to both sides first to isolate x.
3x-4<8
<u>+4 +4</u>
3x<12
Divide both sides by 3.
3x<12
<u>/3 /3</u>
x<4
2) 2x+2>4
Subtract both sides by 2 to isolate x.
2x+2>4
<u>-2 -2</u>
2x>2
Divide both sides by 2.
2x>2
<u>/2 /2</u>
x>1
Hope this helped!! Have an amazing day :3
