Answer:

<h2>P=4+√5+√13 the answer is C</h2>

Step-by-step explanation:

to find the perimeter , need to find the length(distance of the sides)

D=√(x2-x1)²+(y2-y1)²

D between BE and BD and ED

d of BE :

B(1,2) E(5,2)

D of BE = √(5-1)²+(2-2)²=√4²=4

<h2>BE=4</h2>

D of BD : (1,2) , (2,4)

D=√(2-1)²+(4-2)² = √1²+2² = √5

<h2>BD=√5</h2>

ED : (5,2) , (2,4)

d=√(2-5)²+(4-2)²=√-3²+2² =√13

<h2>ED=√13</h2>

the perimeter= BE+BD+ED

<h2>P=4+√5+√13</h2>

I believe the answer would be C, but I'm not sure.

In computer technology, a kilobyte is 2^10 bytes in size . A gigabyte is 2^30 bytes in size . The size of a terabyte is the prod
melomori [17]
Kilobyte = 2^10 bytes
gigabyte = 2^30 bytes
terabyte is the product of a kilobyte and a gigabyte....so we multiply

2^10 * 2^30 = 2^(10 + 30) = 2^40 <== a terabyte

** exponent rule : a^b * a^c = a^(b + c)

The times to process orders at the service counter of a pharmacy are exponentially distributed with mean 1 0 minutes. If 100 cus
g100num [7]

Answer:

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.

Step-by-step explanation:

The formula for the probability of an exponential distribution is:

P(x < b) = 1 - e^(b/3)

Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:

p = P(x > 10)

  = 1 - P(x < 10)

  = 1 - (1 - e^(-10/10) )

  = e⁻¹

  = 0.3679

The z-score is the difference in sample size and the population mean, divided by the standard deviation:

z = (p' - p) / √[p(1 - p) / n]

  = (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]

  = 2.7393

Therefore, using the probability table, you find that the corresponding probability is:

P(p' ≥ 0.5) = P(z > 2.7393)

<em>P(p' ≥ 0.5) = 0.0031</em>

<em></em>

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.
