Think about a density curve that consists of two straight-line segments. The first goes from the point (0, 1) to the point (0.7,

1) then the second goes from the point (0.7, 1) to the point (1.3, 0).
a. Sketch this density curve:
b. What is the probability that X falls below 0.5?
c. What is the probability that X lies between 0.7 and 1.3?
d. What is the probability that X lies above 0.2?
e. What is the probability that X is equal to 0.5?

Answer:

b)0.5

c)0.3

d)0.2

e)0.5

Step-by-step explanation:

As we see on the graph, the probability that X falls below 0.5 is 0.5.

the probability that X falls between 0.7 is 1.3 is 0.3. If the line go from the point (0.7,1) to the point (1.3, 1) the probability of X would be 0.6 that is the distance between the two points, but instead is the half because it goes from the point (0.7,1) to the point (1.3, 0).

The probability that X lies above 0.2 is 0.2 and also the probability to X is equal to 0.5 it's also 0.5

Can someone please help
andre [41]

Answer:

x ≥ 1  (how to graph is listed below)

Step-by-step explanation:

To find where we need to plot the line, we first need to solve the inequality for x:

-2x - 3 ≤ -5

(Add three to both sides)

-2x ≤ -2

(Divide both sides by -2, but we can't forget that whenever we multiple or divide by a negative number, the sign flips!)

x ≥ 1

To graph this on the number line, you would put a dot on the 1 and fill it in completely (you fill in the dot for a "___ and equal to" sign.     ex. ≥, ≤)

Then you would make an arrow from the dot to the right on the number line (this is because x must be greater than or equal to 1, so it must be facing in that direction)

Can someone help me with this? thx :)
GrogVix [38]

Answer:

Table 1 is not a function because there are two y-values with the same x-values. Remember... y values can repeat but x values cannot repeat when their corresponding y values are different.

Table 2 is a function.

You would need to omit either (3,7) or (3,-2).

Please vote brainliest! Hope this helps, have a nice day.
