First aspect of the question is typed below.
The shape of the distribution of the time required to get an oil change at a 20-minute oil-change facility
is unknown. However, records indicate that the mean time is 2l.2-minutes, and the standard deviation 3.5 minutes.
Explanation:
Employees bonus $50
35 oil changes between 10:00 am to 12:00pm
n = 35
10% changes
So, the z - score can be calculated using
z-score = InvNorm(0.10)
z-score = -1.28
So, given that,
Standard deviation is 3.5minutes
σ = 3.5 minutes
Mean time is 21.2 minutes
μx = 21.2 minutes
Then,
σx = σ / √n
σx = 3.5 / √35
σx = 0.5916 minutes
Then, Z score can be written as
Z = (x - μx) / σx
-1.28 = (x - 21.2) / 0.5916
Cross multiply
-1.28 × 0.5916 = x - 21.2
-0.7573 = x - 21.2
x = 21.2 - 0.7573
x = 20.443 minutes
There is a 10% chance of being at or below a mean oil-change time of 20.44 minutes
Answer:
the current total contribution margin = 100 x 60% x ($80 - $20) = $3,600 per day
scenario 1: $10 discount
$3,600 = 100 x ?% x ($70 - $20)
$3,600 = $5,000 x ?%
$3,600 / $5,000 = ?%
occupancy rate = 72%
scenario 2: 10% discount
$3,600 = 100 x ?% x ($72 - $20)
$3,600 = $5,200 x ?%
$3,600 / $5,200 = ?%
occupancy rate = 69.23%
True. You should consider the interest threshold while selecting a savings account.
Interest thresholds are the maximum amount that you can keep in your savings account, also referred to as the threshold limit. This means that it is important to choose an account that holds the threshold at an amount that is convenient and suitable to your needs.
The other criteria that need to be taken into account while choosing a savings account are:
- fees and penalties
- lowest balance
- interest rates and interest caps
- fluctuating interest rates
- (APY) annual percentage yield
- (APR)
Simple financial transactions are one benefit of a savings account, as well as interest payments, ATM and debit card services, chequebook and passbook services, net banking and mobile banking, and a minimum average balance.
