Answer:
-2(2+5r)
Step-by-step explanation:
-(7+10r)+3
then you remove the parentheses
-7-10r+3
calculate the sum
-4-10r
factor the expression
-2(2+5r)

Answer:
(a) $133.88
Step-by-step explanation:
The addition of tax multiplies the purchase price by 1+6.45% = 1.0645. The payment of the down payment means the loan amount will be only 1-10% = 0.90 times the amount with tax. So, the loan amount is ...
$22,359(1.0645)(0.90) = $21,420.08
The loan is a secured loan (secured by the vehicle). So, the interest charged is that for a poor credit rating: 7.5%.
One month's interest is ...
I = Prt . . . . . interest on principal P at rate r for t years (1 mo = 1/12 yr)
I = $21,420.08(0.075)(1/12) = $133.88
Answer:
17.1≤x≤23.1
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = x ± z*s/√n
x is the mean yield = 20.1
z is the 80% z-score = 1.282
s is the standard deviation = 7.66
n is the sample size = 11
Substitute
CI = 20.1 ± 1.282*7.66/√11
CI = 20.1 ± 1.282*7.66/3.3166
CI = 20.1 ± 1.282*2.3095
CI = 20.1 ±2.9609
CI = (20.1-2.9609, 20.1+2.9609)
CI = (17.139, 23.0609)
hence the required confidence interval to 1dp is 17.1≤x≤23.1
