A person must enter a 4 digit code to gain access to his cell phone. He will enter codes until he is successful, however he cann

ot try more than 3 times or the phone will lock him out. Let S denote a successful attempt and F denote a failed attempt. What is the sample space for this random experiment?
A) {SSS, SSF, SFS, FSS, SFF, FSF, FFS, FFF}
B) {S, FS, FFS}

Answer:

C) {S, FS, FFS, FFF}

Step-by-step explanation:

The person entering the code needs a success to access the cell phone or the person stops trying when he has failed at all 3 attempts. The possible outcomes are;

(1) The person is successful at first attempt {S}

(2) The person failed at first attempt, successful at second attempt {FS}

(3) The person failed at first and second attempts, successful at third attempt {FFS}

(4) The person failed at the three attempts {FFF}

The sample space is {S, FS, FFS, FFF}

Answer:

a. connect the point (0 , 3) with A

b. connect the origin (0 , 0) with B

c. For A: y = 0.5x +3

For B: y = 0.5x

Step-by-step explanation:

y = ax + b is the general rule for any straight line

a being the slope and b being the y intercept, a is given to be 0.5

y = 0.5x + b, substitute the coordinates of point A

4 = 0.5 *2 +b hence b = 4 - 0.5 *2 = 4 - 1 = 3

so y = 0.5 x + 3 is the equation of the line passing through A

since the second line that passes through B is parallel to the first, hence it has the same slope of 0.5

same procedure, substitute coordinates of B

2 = 0.5 * 4 + b hence b = 2 - 0.5 *4 = 2 - 2= 0

so y = 0.5 x is the equation of the line passing through B

The surface area of a cube is represented by the expression below, where s is the side length of the cube. Find the surface area
Dmitry [639]

Answer:

486 centimeters³

Step-by-step explanation:

Surface area of a cube = 6s²

Where,

s = side length

Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.

s = 9 centimeters

Surface area of a cube = 6s²

= 6 × 9²

= 6 × 81

= 486 centimeters³

Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³

What is the scale factor from triangle WHB to triangle RVM
Studentka2010 [4]

Answer:

.5

Step-by-step explanation:

Going from WHB to RVM means that we need the number to multiply by to get to RVM, the smaller triangle.

Multiplying by .5 is the same as dividing by 2.

20 x .5 = 10

16 x .5 = 8

12 x .5 = 6
