For the trinomial ​3x^2 + 22x + 7, choose two numbers whose product is 21 and whose sum is 22
Lesechka [4]

Answer:

When a trinomial is in the form of ax2 + bx + c, where a is a coefficient other than 1, look first for common factors for all three terms. Factor out the common factor first, then factor the remaining simpler trinomial. If the remaining trinomial is still of the form ax2 + bx + c, find two integers, r and s, whose sum is b and whose product is ac.

Of all the employees,what is the approximate relative frequency of Managers who worked more than 40 hours ?
elena-14-01-66 [18.8K]

Answer:

The approximate relative frequency of Managers who worked more than 40 hours will be  9.3\%.

Step-by-step explanation:

The complete question is mentioned below in the attached diagram.

From the question diagram which is attached below, it is clear that

  • there are total 86 employees, and
  • there are 8 are who work more than 40 hours per week.

Hence, the approximate relative frequency of managers who worked more than 40 hours will be:

                                   \frac{8}{86}=0.093  

Which is is equal to 9.3\%.

Therefore, the approximate relative frequency of Managers who worked more than 40 hours will be  9.3\%.

How to solve this and the steps you took
mr Goodwill [35]

Answer:

n = 16

Step-by-step explanation:

Step 1: Cross multiply

6(n - 7) = 2(2n - 5)

Step 2: Distribute

6n - 42 = 4n - 10

Step 3: Subtract 4n on both sides

2n - 42 = -10

Step 4: Add 42 to both sides

2n = 32

Step 5: Divide both sides by 2

n = 16

Solve for pi please.
Olenka [21]

Answer:

2A / r^2 = pi

Step-by-step explanation:

A = 1/2 pi r^2

Multiply by 2

2A = pi r^2

Divide by r^2

2A / r^2 =  pi r^2/r^2

2A / r^2 = pi
