Answer:b
Step-by-step explanation:
Answer:
1/10.
Step-by-step explanation:
Prob(Spinning a 1) = 1/5.
Prob(Flipping a Head) = 1/2.
Probability of a 1 then a head = 1/5 * 1/2 = 1/10.
Note: we multiply the probabilities because the 2 events are independent.
Given:
The inequality is

To find:
The solution of the given inequality.
Solution:
We have,

Isolate the variables terms on the left side.


Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.


Therefore, the correct option is D.
2x^2 - y when x + 3 and y = -2
2(3)^2 - (-2)
2(9) + 4
18 + 4
22
