Answer:

The part of the expression representing the amount of tax to be paid is;

0.08(507)

Step-by-step explanation:

Here, we want to select the part of the expression that represents the amount of tax Deborah has to pay

From the expression, we have ;

0.08(507) + 50h

Kindly note that we can have 0.08 as 8/100

8/100 is same as 8%

when we represent taxes, it is usually a percentage of something

In that case, the tax part would be ; 0.08(507)

The area of a circle is 8π square units. What is the radius of the circle in simplest radical form?

Sav [38]

Answer:

Step-by-step explanation:

The area of a circle is :A= π r² r : the radius

A= 8π square units

so : π r² = 8π

r² = 8

r = √8 = √(4 × 2) =√4×√2

r = 2√2 units

Among 6 electrical components exactly one is known not to function properly. If 2 components are randomly selected, find the pro

Oksanka [162]

Answer:

66.67% probability that all selected components function properly

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the components are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Desired outcomes:

2 components which function properly, from a set of 5. So

$D = C_{5,2} = \frac{5!}{2!(5-2)!} = 10$

Total outcomes:

2 components, from a set of 6. So

$T = C_{6,2} = \frac{6!}{2!(6-2)!} = 15$

Probability:

$p = \frac{D}{T} = \frac{10}{15} = 0.6667$

66.67% probability that all selected components function properly
