The value of C=1/3 for the probability density function f(x)=cx , 0<x<2.

<h3>What is probability density function?</h3>

The probability density function is a function of a continuous random variable, whose integral across an interval gives the probability that the value of the variable lies within the same interval.

Given that:

f(x)=cx\ \ at\ 0 < x < 2

Here we can see that the value of x is varies as 0,1,2

So at 0,1,2 the value of the function is

f(1)=c\times 1=c\\\\\\f(2)=c\times 2=2c\\\\

So the probability density function is given as:

\sum f(x)=f(1)+F(2)=1\\\\\sum f(x)=c+2c=1

3c=1\\\\c=\dfrac{1}{3}

Hence the value of C=1/3 for the probability density function f(x)=cx , 0<x<2.

A park district has 45 pine trees and 30 oak trees to be planted. They are separating the trees for different areas. They want e
Lady_Fox [76]

Answer:

greatest number of areas that can be created=5

Step-by-step explanation:

given data

Number of pine trees = 45

Number of oak trees = 30

solution

we want area have same number of both trees

so we get here greatest number of area

we find here  greatest common factor of 45 and 30

so Prime factorization of 45 and 30 are

45 = 3 × 3 ×  5

30 = 2 × 3 ×  5

as here GCF = 5

so here greatest number of areas that can be created=5

A consumer survey indicates that the average household spendsμ= $185on groceries each week. The distribution of spending amounts
Vitek1552 [10]

Answer:

P(X>200)=P(\frac{X-\mu}{\sigma}>\frac{200-\mu}{\sigma})=P(Z>\frac{200-185}{25})=P(Z>0.6)

And we can find this probability using the complement rule and with the normal standard table or excel:

P(Z>0.6)=1-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 average household spent of a population, and for this case we know the distribution for X is given by:

X \sim N(185,25)  

Where \mu=185 and \sigma=25

We are interested on this probability

P(X>200)

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X>200)=P(\frac{X-\mu}{\sigma}>\frac{200-\mu}{\sigma})=P(Z>\frac{200-185}{25})=P(Z>0.6)

And we can find this probability using the complement rule and with the normal standard table or excel:

P(Z>0.6)=1-P(z
