Ос
Invest only in international companies
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.
Answer: A- shift his portfolio to a more moderate approach
Step-by-step explanation:
It’s a simple strategy

On a trip, you drove 150.75 miles in 2 hours and 35 minutes. At this rate, how long will it take you to travel 450 miles? Round your answer to the nearest minute.
Answer:
450:155 min
450/150.75=2.98
155 x 2.98=462.69 minutes
=7 hours 43 minutes
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?
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

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?
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
What is an irrational number between 15.3 and 15.4?
Answer:
18.4 what the right answer
Step-by-step explanation:
Solve for x
- 1/5 (x – 4) = -2
Enter your answer in the box.
x =
-1/5 (x - 4) = -2
(-1/5)x + (4/5) = -2
-2 can be turned into -10/5
(-1/5)x = (-10/5) - (4/5)
(-1/5)x = -14/5
multiply by -5 on both sides
x = 14

when a number, n, is increased by two and then the result is divided by five the quotient is equal to 14. write an equation and solve it to find the value of n.
NEED STEP BY STEP EXPLANATION
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.
