Answer:

0.5

Step-by-step explanation:

[20+(2.5×3)]-3^3

2.5×3=7.5

[20+7.5]-3^3

27.5-3^3

3^3=27

27.5-27=0.5

A un paciente se le toma la temperatura a las 7 am, 9 am, 2 pm y a las 4 pm. La primera segunda y cuarta lecturas son de 66 grad
Gnesinka [82]

Answer:

94

Step-by-step explanation:

(Lo siento, español no es mi primero lingua, pero intentaré mi mejor :) )

La ecuación is (66 + 90 + x + 94)/4 = 86

Multiple los dos de los lado por 4.

66 + 90 + x + 94 = 344

Hace 66 + 90 + 94, y ponelos a la otro lado con sustracción.

X = 94

94 es la tercera lecture.

Suppose that telephone calls arriving at a switchboard follow a Poisson process with an average of 5 calls per minute. What is t
postnew [5]

Answer:

The correct answer is "0.0842".

Step-by-step explanation:

Given:

X = 5

By using the Poisson's distribution formula, we get

The probability will be:

⇒ P(x=2)=\frac{\lambda^x.e^{-\lambda}}{x!}

By substituting values, we get

                   =\frac{(5)^2\times e^{-5}}{2!}

                   =\frac{25\times e^{-5}}{2!}

                   =0.0842

Find 5 points that satisfy the equation y= 12+2x
Goshia [24]
We start by finding the intercept of the line: what does y equal when x=0? and what does x equal when y=0?
• intercept in x
y = 12 + 2x
0 = 12 + 2x
-12 = 2x
-6 = x
• intercept in y
y = 12 + 2x
y = 12 + 2(0)
y = 12 + 0
y = 12
Now we find three more points giving y a value and finding x
y = 12 + 2x
2 = 12 + 2x
2-12 = 2x
-10 = 2x
-5 = x

y = 12 + 2x
6 = 12 + 2x
6 - 12 = 2x
-6 = 2x
-3 = x

y = 12 + 2x
14 = 12 + 2x
14 - 12 = 2x
2 = 2x
1 = x

Notice how I gave y even numbers as values since we would have to divide with 2 at the end.
