Answer:
2.28 %
Step-by-step explanation:
It is stated that battery life distribution is normal. First we need to find out where 65 hour battery life in this distribution falls by finding its z-score. We can use the following formula
z(x)=
where
- X the point we are looking to find its z-score, which is 65
- M is the mean of the sample, which is 75
- s is the standard deviation of the sample, which is 5
Replacing these numbers in the formula, z-score of the 65 hour battery life :
z(x)=
=-2
All the batteries fail within the first 65 months if their z-score is smaller than -2. Or we can state this also as: P(z≤-2) which is 0.0228
Thus 2.28 % of the batteries will fail within the first 65 months of use.
The function g represents y=x^2-3. The difference between function f and g is that g has a y intercept of -3
A. Using the Simple Discount Note formula:
Proceeds = Maturity Value (MV) - Discount; MV = Face Value
Discount = MdT; M = Maturity; d = discount; T = Time
= $12,300*12%*15/12
Discount = $1,845
Proceeds = MV - Discount
= $12,300 - $1,845
Proceeds = $10,455
B. Using the Simple Interest Note formula:
Effective Rate of Interest = Interest / Proceeds*Time
= $1,297.50 / $17,300*180/360
= .15
Effective Rate of Interest = .15 or 15%
C. False. Discount is the interest charged to the principal of the loan.
