Answer:
51
Step-by-step explanation:
Given
P(x) = 2x³ + 4x² - 10x - 9, then
P(a) = 2a³ + 4a² - 10a - 9 ← substitute x = a into P(x)
To evaluate P(3) substitute a = 3 into P(a)
P(3) = 2(3)³ + 4(3)² - 10(3) - 9 = 54 + 36 - 30 - 9 = 51
Since P(3) ≠ 0 then (x + 3) is not a factor of P(x)
Answer:
Option A,B,C and D is correct
Step-by-step explanation:
As we can see , the data set for April month has longer time duration taken for completing homework as compared to the time taken during the month of April. Hence, option A is correct.
Option B is also correct because most of the instance of time taken for doing homework is greater for month of April as compared to the month of March
Median value for the month of march = 25 and median value for the month of April is (30+35)/2 = 32.5. Hence, Option C is correct
There is greater variability for the month of April. Hence, option D is correct
