The solid line indicates that the line itself is included in the solutions.  That the shaded area is to the left, or under, the line means that y≤the line.

To find the equation of the line you first find the slope or m using any two points.

m=(y2-y1)/(x2-x1)  in this case you are given (2,-5) and (-2, 3) so

m=(3--5)/(-2-2)

m=8/-4

m=-2

So far for y≤mx+b we have:

y=-2x+b  using either point we can solve for b, I'll use (2,-5)

-5=-2(2)+b

-5=-4+b

-1=b

So the line is:

y=-2x-1  and since y≤ the line:

y≤-2x-1

Answer the following questions about the standard normal random variable Z. (Use 4 decimal places in your answers to parts a. th
Mashcka [7]

Answer:

a) 0.6636

b) 0.0951

c) 0,9474    

d)  0.0047

e) 0.9957  

f)   0.1308  

Step-by-step explanation:

We look in tables z values and then we see carefully aereas inside normal curve

a) P[- 1.46 < z < 0.63 ]     point 1.46 from table 0.0721  this s th area from value -1.46 to the left . And the value  z = 0.63  corresond to the area 0.7357 which includes the area between 1.46 to the left tail, then we have to subtarct and get 0.6636 .

P[- 1.46 < z < 0.63 ] = 0.6636             66.36 %

b) P [ 0 < z < 1.31 ] we just need the area for point 1.31   that is 0.0951

P [ 0 < z < 1.31 ] = 0.0951                   9.51 %

c)  P [z > - 1.62  ] = 1 - 0.0526

P [z > - 1.62  ] = 0,9474                       94.74 %

d) P[z < - 2.6 ] =   0.0047                       0.47 %

e) P [ z < 2.63 ] = 1 - 0.0043

P [ z < 2.63 ] = 0.9957                         99.57 %

f) P [ -2.58 < z < -1.1 ]  =  0.1357 - 0.0049 =  

P [ -2.58 < z < -1.1 ]  =  0.1308              13.08 %

Mi abuela dio a luz a mi padre, cuando ella tenia menos de 20 años,y yo naci cuando mi padre tenia mas de 25años , si mi padre t
Svetllana [295]

Answer:

The father was either 29 or 28 years old when the author of the question was born.

El padre tenía 29 o 28 años cuando nació el autor de la pregunta.

Step-by-step explanation:

English Translation

My grandmother gave birth to my father, when she was under 20 years old, and I was born when my father was over 25 years old, if my father is now under 45 years old and I was in my fourth year of high school, how old is my father when I was born.

Solution

Assuming that the author of the question is a typical fourth year high school student.

The age of fourth year high school students normally range from 16 to 17.

The father is currently 45 years old, so the age of the father when the author of the question was born is given as

(45 - 16) or (45 - 17)

= 29 or 28 years old.

which satisfies the condition given in the question that the father was more than 25 years old!

Hope this Helps!!!

In Spanish/En español

Asumiendo que el autor de la pregunta es un típico estudiante de secundaria de cuarto año.

La edad de los estudiantes de cuarto año de secundaria normalmente oscila entre 16 y 17.

El padre tiene actualmente 45 años, por lo que la edad del padre cuando nació el autor de la pregunta se da como

(45 - 16) or (45 - 17)

= 29 o 28 años.

que satisface la condición dada en la pregunta de que el padre tenía más de 25 años!

¡¡¡Espero que esto ayude!!!

Find the sum of 136 +212. expkain why u did r did not regroup
mario62 [17]
Line up 136 and 212 with 136 on top and 212 on the bottom.

  136
+212
____

now add up the end numbers, 6 and 2. That's 8. Since 8 is only a single-digit number, it fits in the space. Write that down under 6 and 2. 
Next, add up the middle numbers, 3 and 1. That's 4, it fits in the space, so you don't need to regroup here either. 
Now add up the first number in each, and that adds up to 3. 

The sum is the number you wrote down! It should look something like this.

  136
+212
____
348

You can say that the sum of these numbers is 348, and you did not have to regroup because the sums of each digit was under 10!
