Answer: $46.75
Step-by-step explanation:
10% of $55=$5.50 plus
5% of $55=$2.75
Total
15% of $55 =$8.25
$55.00 less $8.25
=$46.75
Answer:
So the bigger array is 12 and 25
Step-by-step explanation:
Let's do a multiplication of this array first and Know it's result.
3 times five and 4 times 5. = (3*5) and (4*5)
= 15 and 20
Multiplying further gives us
= 15 * 20=300.
So to combine to get the bigger array.
We must get back 300 as the result of our product.
Let's multiply the row(x) with the row(x)
And the column (y) with column(y)
3 times five and 4 times 5.= 3*4 and 5*5
So the bigger array is 12 and 25
To check.
12*25 = 300
Proved.
c) 4/5 .....................
Answer: 90% confidence interval would be (0.448, 0.552).
Step-by-step explanation:
Since we have given that
x = 125
n = 250
So, 
We need to find the 90% confidence interval.
so, z = 1.64
So, interval would be

Hence, 90% confidence interval would be (0.448, 0.552)
Answer:
(A)
Step-by-step explanation:
Cost of car = $21,349
Down payment = $3000
Remaining amount left = $18,349
Monthly payments (A) = $352
n = Total periods = 5years = 5*12= 60
P(loan amount) = 18,349
r = rate of interest monthly = r/12
Using formula, A = 
352 = [tex]\frac{18349\frac{r}{12} }{1-(1+\frac{r}{12})^{-60} }[/tex
= 0.059(approx)
Annual percentage rate = 5.9%
