Line segment L N is tangent to circle O at point M and QM is a diameter.
Oksana_A [137]

Answer:

The measure of ∠QML is 90°

The measure of ∠PMN is 117°

Step-by-step explanation:

In circle O:

  • MQ is a diameter
  • LN is a tangent to circle O at point M
  • PM and RQ are secants
  • m∠PMO is 27°
  • m∠MQR is 42

∵ MQ is a diameter of circle O

∵ LN is a tangent to circle O at point M

- A diameter is perpendicular to a tangent at the point of

 contact between them (one of end-point of the diameter)

∴ QM ⊥ LN at point M

∴ m∠QML = m∠QMN = 90°

The measure of ∠QML is 90°

∵ m∠PMN = m∠PMO + m∠QMN

∵ m∠PMO = 27° ⇒ given

∵ m∠QMN = 90° ⇒ proved

∴ m∠PMN = 27 + 90

∴ m∠PMN = 117°

The measure of ∠PMN is 117°

Which statement best compares the spread of the data sets?
MrRa [10]

Answer:

Choice B is correct

Step-by-step explanation:

The Interquartile Range (IQR) for Florida, 11, is greater than the IQR for Australia, 4.

The spread of a data set is a measure of the dispersion or variability of the data set. The spread can be measured by various statistical quantities depending on the nature of the data (skewed or symmetric);

The IQR

Variance

Standard Deviation

Range

A box plot is a graphical representation of the five number summary;

The minimum, first quartile, median, third quartile, and the maximum value in that order.

The IQR is defined as;

third quartile - first quartile

With this definition, the Interquartile Range (IQR) for Florida is;

28 - 17 = 11

while the Interquartile Range (IQR) for Australia is;

14 - 10 = 4

Therefore, the Interquartile Range (IQR) for Florida, 11, is greater than the IQR for Australia, 4.

Del dinero que tenía gasté 1/3 en comida y 1/8 en pasaje, quedándome aún 39 pesos. ¿Cuánto tenía al principio?
ruslelena [56]

Answer: 72 pesos.

Step-by-step explanation:

Supongamos que al principio tenias X, donde X representa la cantidad de dinero que tenias en un principio.

Gastaste:

X/3 en comida

X/8 en pasaje.

Entonces el gasto total es:

X/3 + X/8 = X*(1/3 + 1/8) = X*(11/24)

Entonces el dinero que te queda es:

X - X*(11/24) = X*(13/24) = 39 pesos.

X = (24/13)*39 pesos = 72 pesos

Al principio tenias 72 pesos.
