D. Assign the integers 00 through 84 to people with Rh positive blood and the integers 85 through 99 to people with Rh negative blood.
Step-by-step explanation:
If you want to simulate a percentage, you need to have 100 possible events. If you use 1-100, the range will be 1-85 for positive and 86-100 for negative. Looking at the option its all using 99 as the ceiling, so we use 0-99. Since we use 0, then you have to subtract 1 on the number range. There are 85% chance of Rh-positive, so the assigned number will be
1 through 85
(1-1) through (85-1)
0 through 84
The range for Rh-negative will be:
86 through 100
86-1 through 100-1
85 through 99
Option B is wrong because it assigns 00 through 84 to people with Rh negative blood, not Rh-positive. The right answer will be option D.
a + b ≥ 30 b ≥ a + 10
Step-by-step explanation:
Step 1: Define
+a
+b
b is the bigger integer
Step 2: Write inequalities
"The sum of two positive integers, a and b, is at least 30."
This means that the combined value, a + b, must be greater than or equal to, ≥, 30.a + b ≥ 30"The difference of the two integers is at least 10."
We know that the difference must be positive, as it has to be at least, ≥, 10.Since b is the greater number, a must be subtracting from it, or else we would get a negative numberb - a ≥ 10b ≥ a + 10The system of inequalities which represent the value of a and b are b + a 30 and
b - a 10
Step-by-step explanation:
Given as :
Statement first
The sum of two positive integers, a and b, is at least 30.
Statement second
The difference of the two integers is at least 10.
Now, According to question , b is the greater integer
So, From statement first
b + a 30
And , From statement second
b - a 10
So, from the two given statements The relation of inequalities are
b + a 30 and b - a 10
Hence The system of inequalities which represent the value of a and b are b + a 30 and b - a 10 Answer
a + b ≥ 30, b ≥ a + 10, the system of inequalities could represent the values of a and b
option A
Step-by-step explanation:
Here we have , The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater integer, We need to find which system of inequalities could represent the values of a and b . Let's find out:
Let two numbers be a and b where b>a . Now ,
The sum of two positive integers, a and b, is at least 30According to the given statement we have following inequality :
⇒
The difference of the two integers is at least 10According to the given statement we have following inequality :
⇒
⇒
⇒
Therefore , Correct option is A) a + b ≥ 30, b ≥ a + 10

Givens
The sum of two positive integers is at least 30.Their difference is at least 10.b is greater than a.With this information, we can find a system of inequalities. Remember that "at least" means that the sum of these number is 30 or more, and their difference is 10 or more. So
The solution of this system is attached. Remember that the solution of a system of inequalities is a graphic solutions, the intersection of all three areas is the solution.
However, the problem is just asking for the system that could represent this situation. So, the answer is
It will provide an instant answer!
