Answer:
$121.5
Step-by-step explanation:
$180 × 0.25 = $45 <-- because it is a discount, we will subtract
$180 - $45 = $135 <-- price with 25% discount
$135 × 0.10 = $13.5
$135 − $13.5 = $121.5
Heya !
In mathematics, the complex conjugate root theorem states that if P is a polynomial in one variable with real coefficients, and a + bi is a root of P with a and b real numbers, then its complex conjugate a − bi is also a root of P.
Here , one complex root is given -6i hence , the other must be 6i.
Hope it helps you ! :)
The IQR of the data set is choice C: 9.
To find the IQR, you have to first put the numbers in order.
The order is: 10 12 15 17 19 21 23
The IQR is the difference between the first quartile and the third quartile.
Those values are 12 and 21.
21 - 12 = 9
