Answer:

[-1, infinity)

Step-by-step explanation:

I must assume that you meant y = √(x - 5) - 1.

The range of the square root function is [0, infinity.

If 1 is subtracted from the square root function, the range of the resulting function is [-1, infinity).

Find the surface area of composite figure. use 3.14 for π. round to the nearest tenth

ExtremeBDS [4]

Combining of the two cylinders gives a composite figure that has the surface area of a solid cylinder of radius 7 mm and height 6 mm, such that the surface area of the figure is approximately 571.5 mm².

<h3>Which method can be used to find the surface area of the figure?</h3>

Radius of the inner cylinder, r = 3 mm

Radius of the outer cylinder, R = 7 mm

Height of the cylinders, h = 6 mm

Given that the inner cylinder exactly fits into the outer cylinder, we have;

The surface area of the composite figure is the surface area of the hollow outer cylinder + The area of the top and bottom of the inner cylinder.

Which gives;

The surface area of the composite figure, A, is the surface area of a solid cylinder, using the dimensions of the hollow outer cylinder.

A = 2•π•R² + 2•π•R•h

Which gives;

A = 2 × π × 7² + 2 × π × 7 × 6

Where, π = 3.14, we have;

A = 2 × 3.14 × 7² + 2 × 3.14 × 7 × 6 ≈ 571.5

The surface area of the composite figure, A ≈ 571.5 mm²

Marcos gana S/18,50 por hora y se le descuenta

Talja [164]

Answer:

$76,9

Step-by-step explanation:

Para calcular cuánto ganó Marcos ese día, tienes que multiplicar el salario por hora por el número de horas que trabajó y restarle el valor por los minutos que llegó tarde que es el resultado de multiplicar los minutos que llegó tarde por el valor a descontar por minuto:

salario: $18,50 por hora

número de horas trabajadas: 5

descuento por tardanza: $1,20 por minuto

número de minutos de tardanza: 13 minutos

salario del día=($18,50*5)-($1,20*13)

salario del día=$92,5-$15,6

salario del día=$76,9

De acuerdo con esto, el salario que Marcos ganó ese día es $76,9.

Of all the people applying for a certain job, 80% are qualified and 20% are not. The personnel manager claims that she approve

motikmotik

Answer:

69.23% probability that a person is not qualified if he or she was not approved by the manager.

Step-by-step explanation:

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

In this problem, we have these following probabilities:

80% probability that a person is qualified

20% probability that a person is not qualified.

90% probability that a qualified person is approved.

10% probability that a qualified person is not approved.

10% probability that an unqualified person is approved.

90% probability that an unqualified person is not approved.

Find the probability that a person is not qualified if he or she was not approved by the manager.

Desired outcomes

Unqualified and not approved.

20% are not qualified. Of those, 90% were not approved. So

$0.9*0.2 = 0.18$

Total outcomes:

Qualified and not approved or unqualified and not approved.

80% are qualified. Of those, 10% were not approved

20% are not qualified. Of those, 90% were not approved. So

$0.8*0.1 + 0.9*0.2 = 0.26$

Probability

$P = \frac{0.18}{0.26} = 0.6923$

69.23% probability that a person is not qualified if he or she was not approved by the manager.
