Suppose the number of births that occur in a hospital can be assumed to have a Poisson distribution with parameter = the average

birth rate of 1.8 births per hour. What is the probability of observing at least two births in a given hour at the hospital?

Answer:

0.5372

Step-by-step explanation:

Given that the number of births that occur in a hospital can be assumed to have a Poisson distribution with parameter = the average birth rate of 1.8 births per hour.

Let X be the no of births in the hospital per hour

X is Poisson

with mean = 1.8

the probability of observing at least two births in a given hour at the hospital

= P(X\geq 2)\\= 1-F(1)\\= 1-0.4628\\= 0.5372

the probability of observing at least two births in a given hour at the hospital = 0.5372

Rewrite 19/5 as a mixed number.<br> 1. 4^2/5<br> 2. 3^4/5<br> 3. 5^3/4<br> 4. 4^1/5
Nadusha1986 [10]

Answer:

  • 3 4/5
  1. 3 1/5
  2. 16 1/5
  3. 31 1/4
  4. 4/5

Step-by-step explanation:

An improper fraction is converted to a mixed number by doing integer division and expressing the remainder as a fraction with the divisor as the denominator.

... 19/5 = (3·5 +4)/5 = 3 4/5

The expressions involving exponents are evaluated to mixed numbers according to the Order of Operations. The exponent is evaluated before division, so ...

1. 4^2/5 = (4^2)/5 = 16/5 = 3 1/5

2. 3^4/5 = (3^4)/5 = 81/5 = 16 1/5

3. 5^3/4 = (5^3)/4 = 125/4 = 31 1/4

4. 4^1/5 = (4^1)/5 = 4/5

_____

If you intended fractional exponents, according to the Order of Operations, you need to put that fraction in parentheses. The denominator of the fraction is the root of the base number to the numerator power.

... 4^(2/5) = (4^2)^(1/5) = 16^(1/5) = \sqrt[5]{16}

12:36 1 hour
1:36 2 Hour
1:36 plus 24 mins is 2 but 25 mins left of the movie so then you just add 25 to 2 hours which is 2:25 the movie ended at 2:25 a.m

Calculate s26 for the arithmetic sequence in which a14=4.1 and the common difference is d=1.7
sweet-ann [11.9K]

Answer:

The value of s_{26}=84.5

Step-by-step explanation:

We have given  a_{14}=4.1

d=1.7

We have to find s_{26}

So, a_{14}=a+13d from the formula

a_n=a+(n-1)d

When n=14

a_{14}=a+(14-1)(1.7)=a+13(1.7)

4.1=a+22.1

-18=a

a=-18

Using the formula:

s_n=\frac{n}{2}[2a+(n-1)d

When n=26

s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]

On simplification we get:

s_{26}=84.5
