Answer:
k = 6
Step-by-step explanation:
Solution:
p(x) = 2x^3 + 5x^2 - x - k
x + 2 = 0
x = -2
p(-2) = 2(-2)^3 + 5(-2)^2 - (-2) - k
0 = -16 + 20 + 2 - k
0 = 6 - k
Therefore, k = 6

Answer:
46
Step-by-step explanation:
Angle Formed Outside = 1/2(Difference of Intercepted Arcs)
The arcs are 226 and (360 -226 =134)
y = 1/2 ( 226 - 134)
y = 1/2( 92)
y =46
Answer:
P(B/C) = 0.3333
Step-by-step explanation:
let's call B the event that a woman was wearing a belt and C the event that a woman was carrying a purse.
The probability P(B/C) that a woman was wearing a belt, given that the woman was also carrying a purse can be calculated as:
P(B/C) = P(B∩C)/P(C)
Where P(C) is the probability that a woman was carrying purse and P(B∩C) is the probability that the woman was both carrying purse and wearing belt.
So, P(C) is calculated as:
P(C) = 18 / 30 = 0.6
Because there were 30 women that walked by in an hour and of those women, 18 were carrying purses.
At the same way, P(B∩C) is equal to:
P(B∩C) = 6 / 30 = 0.2
Finally, P(B/C) is equal to:
P(B/C) = 0.2/0.6 = 0.3333
