Answer:

The ladder reach 10.58 feet

Step-by-step explanation:

In this problem a rectangle triangle is formed, with hypotenuse = 11 feet, a side = 3 feet and the other side is the unknown, i. e., how high on the house the ladder reach.  

From Pythagorean theorem:

hypotenuse^2 = side^2 + side^2

11^2 = 3^2 + side^2

side^2 = 11^2 - 3^2

side = sqrt(112)

side = 10.58 feet

Use Pythagoras theorem
 11^2 = h^2 + 3^2  where h is the height of ladder agaianst the wall

h^2 = 11^2 - 3^2
       =(11+3)(11-3) = 14 * 8 =  112
h = sqrt 112 =  10.58 ft

Solve by elimination:<br> 2x + 4y = 34<br> x+4y = 27<br> A (7,-5)<br> B (6,6)<br> (7,5)<br> (5,7)
julsineya [31]

Answer:

(7,5)

Step-by-step explanation:

{2x + 4y = 34

{4y = 27 - x

2x + 27 - x = 34

x=7

4y = 27 - 7

y = 5 so the answer is ( 7,5)

Answer:

a)P [ z > 1,38 ] = 0,08379

b) P [ 1,233 < z < 2,43 ]  = 0,1012

c)  P [ z > -2,43 ]  = 0,99245

Step-by-step explanation:

a) P [ z > 1,38 ] = 1 -  P [ z < 1,38 ]

From z-table  P [ z < 1,38 ] = 0,91621

P [ z > 1,38 ] = 1 - 0,91621

P [ z > 1,38 ] = 0,08379

b)  P [ 1,233 - 2,43 ]  must be  P [ 1,233 < z < 2,43 ]

P [ 1,233 < z < 2,43 ]  = P [ z < 2,43 ] - P [ z > 1,233 ]

P [ z < 2,43 ]  = 0,99245

P [ z > 1,233 ] = 0,89125    ( approximated value  without interpolation)

Then

P [ 1,233 < z < 2,43 ]  = 0,99245 - 0,89125

P [ 1,233 < z < 2,43 ]  = 0,1012

c) P [ z > -2,43 ]

Fom z-table

P [ z > -2,43 ] = 1 - P [ z < -2,43 ]

P [ z > -2,43 ] = 1 - 0,00755

P [ z > -2,43 ]  = 0,99245
