This is a proportional problem.
The distance 'd' corresponds to the 9 inches.
The 7-ft pin corresponds to the size 's'.
Convert 7ft to 7/3 yds. This way you have equal ratio of yds to inches.
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:
11 km/hr.
Step-by-step explanation:
Given information:
Simulated speed = 20/km/h
Time = 15 mins = 1/4 hr = 0.25 hr
Distance Covered as per simulated speed = 
Position of Julian according to the app =
.
Actual distance covered by the bike is

Formula for speed:



Therefore, the average speed of Julian is 11 km/hr.
Answer:
z=16
Step-by-step explanation:
-7(z-6)= -70
combine -7 with the bracket
-7z + 42 = -70
-42 -42
-7z = - 112
divide both sides by -7
-7z/-7 = -112/-7
z = 16
check
-7(z-6)= -70
-7(16-6)= -70
combine
-112+42= -70
-42 -42
-112 = -112
