PLEASE HELP! A basket contains four apples and five peaches. Three times, you randomly select a piece of fruit, return it to the
Lana71 [14]

Answer:  

  • 100 / 729    

Explanation:  

The general formula to calculate the probability of each event is:  

  • Probability = number of positive (desired) outcomes / number of total outcomes  

Number of apples = 4

Number of peaches = 5  

Number of fruits = 9  

Since the three times you return the radomly selected fruit, and then mix it, the three times the probability is not affected by the previous selection; so, these are independent events, and you can calculate the probability of the joint event as the product of the probabilities of each individual event.  

  • <u>First time:  </u>

       Probability of getting an apple = number of apples / number of fruits = 4 / 9  

  • <u>Second time:  </u>

       Probability of getting a peach = number of peaches / number of fruits = 5 / 9  

  • <u>Third time:  </u>

<u />

       Probability of getting a peach = number of peaches / number of fruits = 5 /9  

  • <u>Joint probability:</u>

       = (4/9) × (5/9) × (5/9) = (4 × 5 × 5) / (9 × 9 × 9) = 100 / 729

Calculate The Constant of Proportionality (k) and Write an Equation for the line in the Graph Below:
S_A_V [24]

Answer:

k = ½

Equation => y = \frac{1}{2}x

Step-by-step explanation:

Constant of proportionality (k) = y/x

Using a point on the graph, (6, 3),

k = y/x = 3/6 = ½

k = ½

Equation of the line:

Plug in the value of k into y = kx (slope-intercept form of equation for proportional relationship)

Thus:

y = \frac{1}{2}x
