Answer:
x = 7 & y = 8
Step-by-step explanation:
We know that
Mean = Sum of terms/Total terms
=> Mean = 4 + 6 + x + y + 10/5
=> Mean = 20 + x + y/5
Now,
Median = (n + 1)/2
=> Median = (5 + 1)/2
=> Median = 6/3
=> Median = 3rd term = x
So,
x = 20 + x + y/5
x × 5 = 20 + x + y
5x = 20 + x + y
5x - x = 20 + y
4x = 20 + y
Since x and y are in order so,
Possible outcomes will be 7,8 & 9
(7,8) & (8,9) & (7,9)
Taking x = 7 and y = 8
4(7) = 20 + 8
28 = 28
Hence,
x = 7 and y = 8
Answer:
A
Step-by-step explanation:
The parabola ends at 4, and therefore the range is all real numbers under 4
N^2 - 4n + n^2 + 8n = n^2 - 13n + n^2 + n + 16
-4n + 8n = -13n + n + 16
-4n = -12n + 16
4n + 12n = 16
16 = 16
n = 1
$5000 × 1.1%=$55
$55 × 12 mos. in a year= $660 yearly on this percent
calculate
$660 × 8 years from now =$5280
so the answer would be 1.1% I assume
The original price of the car before 4 years will be $23,032.
<h3>What is an exponent?</h3>
Consider the function:
y = P (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, P = original amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
A Naomi's car exponentially depreciates at a rate of 8% per year.
If Nina bought the car when it was 4 years old for $16,500.
Then the original price will be
16500 = P(0.92)⁴
16500 = 0.716P
P = $ 23,032
