Answer:

Height, = 6.5

Base, = 31.5

Step-by-step explanation:

Let :

Height, h = h

Base, b = h + 25

Perimeter, P. of rectangle = 76

P = 2(b + h)

76 = 2(h + h + 25)

76 = 2(2h + 25)

76 = 4h + 50

76 - 50 = 4h

26 = 4h

h = 6.5

b = h + 25

b = 6.5 + 25

b = 31.5

Height, = 6.5

Base, = 31.5

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 47.047.0 and
alisha [4.7K]

Answer:

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is between c and d is given by the following formula

P(c \leq X \leq d) = \frac{d - c}{b-a}

For this problem, we have that:

a = 47, b = 57, c = 51.5, d = 51.75. So

P(c \leq X \leq d) = \frac{d - c}{b-a}

P(51.5 \leq X \leq 51.75) = \frac{51.75 - 51.5}{57 - 47} = 0.025

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.

Juan compró un led TV en cuotas que costó $ 76.000=. Si le falta pagar 3 cuotas y ya pagó $ 47.000, ¿Cuál es el valor de cada cu
Murrr4er [49]

Respuesta:

$ 9666. 67

Explicación paso a paso:

Costo de TV = $ 76,000

Número de cuotas = 3

Monto ya pagado = $ 47000

Amontof cada cuota fija = Cantidad que queda por pagar / 3

Cantidad que queda por pagar = Costo de TV - Cantidad ya pagada

Cantidad que queda por pagar = $ (76000 - 47000) = $ 29000

Monto de cada cuota fija = $ 29000/3 = $ 9666. 67
