The sandwich shop has 6 employees, but only 3 people need to work at any one time. The manager wants to have a different group of people work together every day for two weeks. Is that possible?

Answers

Answer: Yes

Step-by-step explanation:

Given that:

Number of employees (n) = 6

Number of employees who can work at a time (r) = 3

To know of its possible for different groups of employees to work for two wweka, then, the number of different groups or combination must be greater Than or equal to 14 (two weeks) ; Assume (1 week = 14 days)

Using the combination formula :

nCr = n! ÷ (n - r)!r!

6C3 = 6! ÷ (6 - 3)!3!

6C3 = 6! ÷ 3!3!

6C3 = (6*5*4) ÷ (3*2*1)

6C3 = 120 / 6

6C3 = 20 ways

Hence, 20 different groups of 3 employees can be made from all 6 employees. Hence, it is possible to have different groups work for two weeks

Answers

Answer:

The strategy that his financial advisor may suggest is:

Shift his portfolio to a more moderate approach.

Step-by-step explanation:

The strategy that got Ronald to this position must have been a high-risk portfolio.  Therefore, his adviser should convince him to pursue a more moderate approach to reduce the losses and ensure recovery.  However, it is known that high-risk investments attract higher returns than moderate-risk investments.  The loss exposure that Ronald has experienced lately may also be cyclical, in which case, it may be more prudent to maintain a long position, as recovery will soon be on the corner.

The value of y is directly proportional to the value of x. If y = 36 when x = 140 what is the value of y whenx x = 70?

Answers

Answer:

The value of y is 18 at x = 70

Step-by-step explanation:

The equation of the directly proportional is y = k x, where k is the constant of proportionality.

∵ The value of y is directly proportional to the value of x

→ By using the equation above

∴ y = k x

∵ x = 140 and y = 36

→ Substitute them in the equation above

∴ 36 = k(140)

∴ 36 = 140k

→ Divide both sides by 140

∵ [tex]\frac{36}{140}[/tex] = k

∴ [tex]\frac{9}{35}[/tex] = k

→ Substitute the value ok in the equation

∴ y = [tex]\frac{9}{35}[/tex] x ⇒ equation of proportionality

∵ x = 70

→ Substitute in the equation to find y

∴ y =  [tex]\frac{9}{35}[/tex] × 70

∴ y = 18

∴ The value of y is 18 at x = 70

Solve for x 3x+7/4 + 2x+1/10 = -1

-1/5 (x - 4) = -2

(-1/5)x + (4/5) = -2    

-2 can be turned into -10/5

(-1/5)x = -14/5

multiply by -5 on both sides

x = 14

Step-by-step explanation:

We have (n + 2)/5 = 14.

=> (n + 2) = 14 * 5 = 70 (multiply 5 on both sides)

=> n = 70 - 2 = 68. (subtract 2 on both sides)

Hence the number n is 68.
