Given:
The set is:
To find:
The number of subsets in set R.
Solution:
Formula for number of subsets in a set of elements is
Number of subsets = ...(i)
We have,
Here, the number of elements are 3. Putting in (i), we get
Number of subsets =
=
Therefore, the number of subsets is 8 and the subsets are and .
Answer: The correct answer is Choice A (6, -1).
Since we have the slope and the equation, we can find the y-intercept and write the equation of the line.
y = -0.75x + b
5 = -0.75(-2) + b
5 = 1.5 + b
b = 3.5
Therefore, the equation is y = -0.75x + 3.5.
Now, just plug in the points until one of that satisfies the equation. The point (6, -1) will satisfy the equation.
Answer:
B.
Step-by-step explanation:
Let w represent the number of weeks.
We have been given that a wrestler currently weighs 189 pounds and is losing 0.5 of a pound per week. So the weight lost by wrestler in w weeks would be .
The total weight of wrestler after w weeks would be:
We are also told that the wrestler needs to weigh more than 165 pounds but less than or equal to 185 pounds. This means that total weight of wrestler should be less than or equal to 185 pounds and greater than 165 pounds.
We can represent this information in an inequality as:
Therefore, option B is the correct choice.
Answer:
Option D is correct
Step-by-step explanation:
When a cube with sides numbered 1 through 6 is rolled one time, the possible events are six i.e. getting {1,2,3,4,5,6} , with equal probability for each.
Of these, the events for which we get 4 or greater are {4,5,6} i.e. three events.
Hence probability of getting 4 or greater is
