Answer:
x = -3
y = 7
Step-by-step explanation:
y = -2x + 1
7 = -2x + 1
<u>-1 -1 </u>
6 = -2x
divide by -2
x = -3
Answer:
54/3-7=11
Step-by-step explanation:
x/3<u>-7=11</u>
+7 +7
(3)x/3=18(3)
x=54
Check
54/3-7=11
18-7=11
11=11
$570.60 because 90/100=.90 so multiply that with 634 with .90 you get 570.60
Answer: 61,750 miles
Step-by-step explanation:
Given : The p-value of the tires to outlast the warranty = 0.96
The probability that corresponds to 0.96 from a Normal distribution table is 1.75.
Mean : ![\mu=60,000\text{ miles}](https://tex.z-dn.net/?f=%5Cmu%3D60%2C000%5Ctext%7B%20miles%7D)
Standard deviation : ![\sigma=1000\text{ miles}](https://tex.z-dn.net/?f=%5Csigma%3D1000%5Ctext%7B%20miles%7D)
The formula for z-score is given by : -
![z=\dfrac{x-\mu}{\sigma}\\\\\Rightarrow\ 1.75=\dfrac{x-60000}{1000}\\\\\Rightarrow\ x-60000=1750\\\\\Rightarrow\ x=61750](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5C%5CRightarrow%5C%201.75%3D%5Cdfrac%7Bx-60000%7D%7B1000%7D%5C%5C%5C%5C%5CRightarrow%5C%20x-60000%3D1750%5C%5C%5C%5C%5CRightarrow%5C%20x%3D61750)
Hence, the tread life of tire should be 61,750 miles if they want 96% of the tires to outlast the warranty.
Answer:
15.14%
Step-by-step explanation:
The formula for APR is stated thus:
APR=fees+interest/principal/n*365*100
principal is the loan amount of $700
fees is the processing fees on the loan which is $50
interest amount=principal*interest %=$700*8%=$56
n is the number of days of the loan which is a year i.e 365 days
APR=($50+$56)/$700/365*365*100
APR=$106/$700/365*365*100
APR=0.151428571
/365*365*100
APR=0.151428571
*100=15.14%
The annual percentage rate on the loan is 15.14% which represents the actual cost on the loan not just the interest cost of 8% annually
