Lisa owns a "Random Candy" vending machine, which is a machine that picks a candy out of an assortment in a random fashion. Lisa

controls the probability of picking each candy. The machine has too much of the candy "Coffee Toffee," so Lisa wants to program it so that the probability of getting "Coffee Toffee" twice in a row is greater than \dfrac{4}{3} 3 4 ​ start fraction, 4, divided by, 3, end fraction times the probability of getting a different candy in one try. Write an inequality that models the situation. Use ppp to represent the probability of getting "Coffee Toffee" in one try.

Answer:

  p² > 4/3(1 -p)

Step-by-step explanation:

Assuming candy selections are independent from one to the next, the probability of getting Coffee Toffee twice in a row will be p². The probability of getting some other selection than Coffee Toffee will be 1-p.

Lisa wants ...

  p² > (4/3)(1 -p)

_____

This has solution p > 2/3.

Find the domain of y=2/3x-1 if the range is {-3, -1, 7, 17}.
White raven [17]
<h3>Answer: The domain is {-3, 0, 12, 27}</h3>

=========================================

Explanation:

First solve for x to get

y = (2/3)x - 1

y+1 = (2/3)x

(2/3)x = y+1

x = (3/2)*(y+1)

-------

Now plug the values given into y. Do so one at a time. Lets plug in y = -3

x = (3/2)*(y+1)

x = (3/2)*(-3+1)

x = 1.5*(-2)

x = -3

So the domain value x = -3 corresponds to the range value y = -3.

-------

Repeat for y = -1

x = (3/2)*(y+1)

x = (3/2)*(-1+1)

x = 1.5*0

x = 0

The domain value x = 0 corresponds to the range value y = -1

-------

Repeat for y = 7

x = (3/2)*(y+1)

x = (3/2)*(7+1)

x = 1.5*8

x = 12

The domain value x = 12 corresponds to the range value y = 7

-------

Repeat for y = 17

x = (3/2)*(y+1)

x = (3/2)*(17+1)

x = 1.5*18

x = 27

The domain value x = 27 corresponds to the range value y = 17

A certain kite has exactly one acute angle, and it measures 16 degrees. What is the maximum whole-number measure of the angle op
kvv77 [185]

Answer:

In order to do so, we need to use basic algebra. The angles in a kite add up to 360 degrees. so we form the following equation.

x + y + y + 16 = 360

x + y + y = 344 <----(360 -16)

Each letter or variable represents an angle measure. the measures of the three angles left. The 16 degrees is on the bottom of the kite and the angle opposite is the top angle. the two side angles will be the same measure that's why they are both y.

x + 2y = 344

The two side angles will be 90 or greater because there is only 1 acute angle. 90 is the smallest number that can be chosen. so we do the following.

Step-by-step explanation:

x + 2(90) = 344

x + 180 = 344

x = 344-180

x = 164

THE MAXIMUM WHOLE NUMBER MEASURE OF THE ANGLE OPPOSITE OF THE 16 DEGREE ACUTE ANGLE IS 164 DEGREES*

F(x) = 9 − x2, x &lt; 3 x − 3, x ≥ 3
liberstina [14]

The table of the function is;

x      f(x)

1       8

2      5

3      0

4      1

5      2

<h3>What are the output values of the x-variables?</h3>

Given the piecewise functions;

           9 - x²,      x < 3

f(x) = {

          x - 3,       x ≥ 3  

For x = 1, since 1 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(1) = 9 - (1)²

f(1) = 9 - 1

f(1) = 8

Hence, we have a point ( 1,8 )

For x = 2, since 2 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(2) = 9 - (2)²

f(2) = 9 - 4

f(2) = 5

Hence, we have a point ( 2,5 )

For x = 3, since 3 is greater than or equal to 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(3) =  (3) - 3

f(3) = 3 - 3

f(3) = 0

Hence, we have a point ( 3,0 )

For x = 4, since 4 is greater than 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(4) =  (4) - 3

f(4) = 4 - 3

f(4) = 1

Hence, we have a point ( 4,1 )

For x = 5, since 5 is greater than 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(5) =  (5) - 3

f(5) = 5 - 3

f(5) = 2

Hence, we have a point ( 3,2 )

Therefore, the table of the function is;

x      f(x)

1       8

2      5

3      0

4      1

5      2
