Answer:

A, D and E

Step-by-step explanation:

Given are the graphs of some functions and we have to find which are the density functions.

Since total probability is always 1, area under the curve must be equal to 1.

APplyig this we find that graph B cannot be density function.

Since probability is non negative graph C cannot be probability density function.

A, D and E are the density graphs.

10) 9 people can paint a bridge in 5 hours,
ale4655 [162]

Step-by-step explanation:

The number of people to paint the bridge is inversely proportional to the number of hours it takes.

(If there are more people, it will take less time etc.)

9 people can paint the bridge in 5 hours.

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.

Fiesta28 [93]

Answer:

Hence the best estimate is population with correct option is 74% and

the value for x=148

Step-by-step explanation:

Given:

A sample of 200

Of which 148 prefer brand new coffee

To Find:

Which statement  is true?

Solution:

n=200

x=148

remaining 52 prefer old ones .

So  estimate population proportion,

p=x/n

p=148/200

p=0.74

p=74 %

Now, when x=52

p=x/n,

p=52/200

p=0.26

p=26%

There is no option for 52 and 24 %

Hence x=148 and p=74%.
