a-1. The manager's return in the month, based on the performance table information, is 1.38%.

a-2.  The manager's underperformance is 0.51% (1.89 - 1.38).

A manager's underperformance occurs when the manager delivers results below expectation.

For instance, the weighted benchmark return was expected to be 1.89%, but the manager achieved an actual weighted return of 1.38%.

Step-by-step explanation: Because the age bracket id between 56 and 59.

Circumference is diameter x pi so the diameter of the circle is 11.

Radius is half the diameter so the radius is 11/2 = 5.5

area of a circle is r^2 x pi

Area = 5.5^2 x pi

5.5^2 = 30.25

Answer:

x is 54˚

Step-by-step explanation:

Answer:

x = 54°

Step-by-step explanation:

Forming the equation,

→ (2x + 2)° = (3x - 52)°

Now the value of x will be,

→ (2x + 2)° = (3x - 52)°

→ 2x - 3x = -52° - 2°

→ -x = -54°

→ [ x = 54° ]

Hence, the value of x is 54°.

The square root of 576 is the inverse of the mathematical operation of squaring the number 24. The square root of a number implies a number whose product with itself gives the initial number. Now we will calculate the square root of 576 using various methods and a few interesting facts and problems too.

The square root of 576 can be written as √576 and (576)1/2

The square of 576 will be a number(a) such that a × a = 576

And 24 × 24 = 576 also -24 × -24 = 576

Therefore, +24 and -24 are the square root of 576

The square root of 576 are +24 and -24.

Both numbers are integers and we know that all integers are rational numbers.

Hence, the square root of 576 is a rational number.

Answer:

7156.6 Women. 28624 Men.

Step-by-step explanation:

I used a web browser and typed "35783/5" That answers the woman part. "4/5 of 35783" Solves the male part.

There are about 4/5th = 28626 male police officers in the city.

Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole.

Given, there are 35,783 police officers in the city.

1/5 of them are females.

That means, 1/5th = 20%

20% are female police officers.

And 100 -20 = 80% are the male police officers.

To find the number of male police officers:

80% of 35,783

= 35783 x 80 / 100

= 28626.4

= 28626 approximated

Therefore, 4/5th male police officers in the city are 28626.

Answer:

she worked 12 hours as a carpenter and 18 hours as a blacksmith

Step-by-step explanation:

Let x = the number of hours for which she worked as a carpenter

Let y = be the number of hours for which she worked as a blacksmith

Total numbers of hours she worked = 30

x + y = 30 (1)

she earned a total $690. She earned $20 dollar per hour as a carpenter and $25 per hour as a blacksmith.

20 x + 25 y = 690 (2)

Equation (2) - 20 × Equation (1),

We get,

5 y = 90 ⇒ y = 18

After substituting this value in equation (1),

We get, x = 12,

Hence, She worked as a carpenter = x hours = 12 hours

And, as a blacksmith = y hours = 18 hours
