Answer:

Picking an even number is an as likely event and it's probability is 1/2

Step-by-step explanation:

We know that the numbers present are 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16

The odd numbers are 1,3,5,7,9,11,13,15

The even numbers are 2,4,6,8,10,12,14,16

There are 8 even numbers and 8 odd numbers.

And also if we pick a number it should be either an even number or an odd number.

Probability(Getting an even number) = \frac{even number}{even number+oddnumber}

Probability = \frac{8}{8+8} = 1/2

Therefore picking an even number is an as likely event and it's probability is 1/2

Olin [163]

Answer:

P(16.5

And using the normal standard table or excel we find the probability:

P(-1.768< Z< 1.768) = P(Z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the avergae number of weeks an individual is unemployed of a population, and for this case we know the distribution for X is given by:

X \sim N(17.5,4)  

Where \mu=17.5 and \sigma=4

Since the distribution for X is normal then, the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu= 17.5, \frac{\sigma}{\sqrt{n}}= \frac{4}{\sqrt{50}}=0.566)

We select a sample of n =50 people. And we want to find the following probability

P(16.5

And using the normal standard table or excel we find the probability:

P(-1.768< Z< 1.768) = P(Z

Plants The world's largest flower, the Giant Raffesia is 91 centemeters in diameter. Use a calculator to find the circumference
Kamila [148]
We know that
circumference=pi*D
where 
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm

the answer is
285.9 cm

Which bacteria sample (A or B) had a smaller initial population? What was that value?
zubka84 [21]

Answer:

B has a smaller initial population of 500

Step-by-step explanation:

Given

See attachment for complete question

Required

The bacteria with the smaller initial population

The initial population is at x = 0

For bacteria A;

A(x) = 600 when x = 0

For bacteria B, we have:

B(x) = 500(2)^x

Substitute 0 for x

B(x) = 500(2)^0

B(x) = 500*1

B(x) = 500

So; when x = 0

A(x) = 600 and B(x) = 500

Because; 500 < 600

We can conclude that B has a smaller initial population of 500
