It may be a because it is rational and they have different ones
Let be "n" the number mentioned in the exercise.
You need to remember that:
1. In Math word problems:
- The word "times" means multiplication.
- The word "twice" indicates that something is multiplied by 2.
- "Sum" is the result of an Addition.
2. In inequalities, "Less than" is represented with the following symbol:
![](https://tex.z-dn.net/?f=%3C)
Then, based on the above, you know that "3 times a number" can be expressed as:
![3n](https://tex.z-dn.net/?f=3n)
And "Twice the same number":
![2n](https://tex.z-dn.net/?f=2n)
Therefore, "The sum of 3 times a number and twice the same number is less than 45" can be represented with the following inequality:
![3n+2n](https://tex.z-dn.net/?f=3n%2B2n%3C45)
The answer is: Option a.
Answer:
Given that the events A and B are mutually exclusive.
P(A) = 0.1
P(B) = 0.4
Mutually Exclusive Events: When two events are Mutually Exclusive it is impossible for them to happen together i.e
If A and B are two events then; P(A and B) = 0
then;
P(A or B) = P(A) +P(B)
By the definition of mutually exclusive events;
P(A or B) = P(A) +P(B) ......[1]
Substitute the values of P(A) = 0.1 and P(B) = 0.4 in [1] we have;
P(A or B) = P(A) +P(B) = 0.1+0.4 = 0.5
Answer:
D
Step-by-step explanation:
3x * 5x = 15x^2
3x * -3 = -9x
4*5x = 20x
4 *-3 = 12
so 15x^2 +(20x -9x) -12 or 15x^2 +11x -12
In 0.75 hour,
Renaldo roll 9.7 x 0.75 = 7.275 miles
Eliza roll 8.2 x 0.75=6.15 miles
--> Renaldo roll 7.275-6.15=1.125 miles farther than E
