A continuous random variable X has cdf F(x)=x² b (a) Determine the constants a and b. for a < 0, for 0 < x < 1, for x &

Karolina [17]

Any proper CDF $F(x)$ has the properties

• $\displaystyle \lim_{x\to-\infty} F(x) = 0$

• $\displaystyle \lim_{x\to+\infty} F(x) = 1$

so we have to have a = 0 and b = 1.

This follows from the definitions of PDFs and CDFs. The PDF must satisfy

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = 1$

and so

$\displaystyle \lim_{x\to-\infty} F(x) = \int_{-\infty}^{-\infty} f(t) \, dt = 0 \implies a = 0$

$\displaystyle \lim_{x\to+\infty} F(x) = \int_{-\infty}^\infty f(t) \, dt = 1 \implies b = 1$

What am I supposed to do hear im confused

natulia [17]

Answer:

Step-by-step explanation:

In No.1

First you find the total number of girls which is 56-20 =36 girls in total

So to get number of boys who watched tennis 20-13=7 boys watched tennis

To get number of girls who didnt watch you do 36-17=19 girls who watched

Then add o get the totals

No.2

First you get the total number of male 80-47=33 males

Next you find the number of females doing phyisics 33-19=14 females

Next you find the number of females doing chemistry by 47-(18 + 14)=15 females

To get the number of males diong chemistry 21-15=6 males

Number of males doing biology 33-(19+6)=8

Then find the remaining totals

2

No. 2 (b)

Because there is a high number of students doing physics and most of them are female

The angle of a quadrilateral are A.P and the common difference is 10°. find the angles.

xxMikexx [17]

Step-by-step explanation:

So the Ap will be x,x+10,x+20,x+30

Sum of the angles of a quadrilateral is 360

x+x+10+x+20+x+30=360

4x+60=360

4x=300

x=75

So the angles are 75,85,95,105
