Billy 20+69=89
89-16=73
Answer: The required probability is 2.24%.
Step-by-step explanation:
Since we have given that
Percentage of people are senior citizens ( 65 years old or older ) = 14%
Percentage of people are under 65 years old = 100-14 = 86%
Probability that senior citizens get the flu each year = 16%
Probability that under 65 years old get the flu each year = 30%
So, Probability that a person selected at random from the general population is senior citizen who get the flu this season is given by
Hence, the required probability is 2.24%.
Answer:
The area of this triangle would be 24.
Step-by-step explanation:
In order to find this, we need to first determine what to use as the base of the triangle. Since when we draw it, the line between G and H is a flat line, it is the easiest to use as a base. Finding the length of the base is easy because we are simply looking for the difference in the x values.
6 - -2 = 8 = base
Now that we have the base, we need to find the height. The height is always the perpendicular line from the 3rd point to the base line. In this case, this would just be the change in y from the other two.
5 - -1 = 6 = height
Now that we have those two distances, we can just use the triangle formula.
A = 1/2bh
A = 1/2(8)(6)
A = 24
You might have made an error the first time you solved for x. I got x = -0.5.
When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:
2x + 3 = 4^(1/2) ... Simplify
2x + 3 = 2
2x = -1
x = -1/2
If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?
The minimum amount of points required to make a plane is 3 points.
