I can't even count so your alone on this jit
Answer:
D is the correct option
Step-by-step explanation:
The roulette can land in any possibly slot and their are 38slots
i.e the total possible event is 38
Green slot = 2
Red slot =18
Black slot =18
P(G)=2/38 =1/19
P(R)=18/38=9/19
P(B)=18/38=9/19.
The roulette will be spun twice and they are independent i.e. the occurrence of one event does not affect the occurrence of the other.
We are looking for the probability of red first and probability of black
P(R n B)=P(R)P(B), since they are independent
P(R n B)=9/19×9/19
P(R n B)= 0.2244
D is the correct option
The expression that represents this inequality must relate both temperatures, then it would look like this: -40°F < x < 140°F.
<h3>How to write this situation with an inequality?</h3>
To express this situation in an inequality we must include the temperature values. Additionally, we must include the greater than (>) or less than (<) symbols to relate the values.
According to the above, the expression would look like this:
Note: This question is incomplete because some information is missing. Here is the information:
A truck driver is driving from Nome, Alaska to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather continuously to make sure the gas in his truck remains in liquid form. The gas he uses freezes at −40° F and evaporates at 140° F.
Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form.

Answer:
D. The sum is a rational expression.
Step-by-step explanation:
the given expression is a/b +c/d
so in the question it is given that b and d are non zero values
a/b is rational number and c/d is a rational number
so if both are rational number , so we know that the sum of rational number is also a rational number.
The right option is D. The sum is a rational expression
