Answer:
Step-by-step explanation:
We know that:
Only employees are hired during the first 3 days of the week with equal probability.
2 employees are selected at random.
So:
A. The probability that an employee has been hired on a Monday is:
.
If we call P(A) the probability that 2 employees have been hired on a Monday, then:
B. We now look for the probability that two selected employees have been hired on the same day of the week.
The probability that both are hired on a Monday, for example, we know is . We also know that the probability of being hired on a Monday is equal to the probability of being hired on a Tuesday or on a Wednesday. But if both were hired on the same day, then it could be a Monday, a Tuesday or a Wednesday.
So
.
C. If the probability that two people have been hired on a specific day of the week is , then the probability that 7 people have been hired on the same day is:
D. The probability is . This number is quite close to zero. Therefore it is an unlikely bastate event.
Answer:
1. Yes
2. Distributive property
3. 2x+8y
4. I'm assuming its supposed to say 5(4x+3)-2x otherwise none of the options work, so the answer for that would be A
5. C

Answer:
Option 1 is correct.
Step-by-step explanation:
Given the equation
we have to choose the best statement describes the above equation.
→ (1)
As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.
⇒ Degree of above equation is 2.
hence, the given equation is quadratic equation.
The general form of quadratic equation is
In variable u: → (2)
Now, compare equation (1) with (2), we say that
The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).
Option 1 is correct.
