If a $6.00 ball was bought for $5.25, what was the percentage of the discount?
andriy [413]

Answer:

B

Step-by-step explanation:

x% of 6 = 5.25

\frac{x}{100} x 6 = 5.25

\frac{(5.25)(100)}{6} = x

x = 87.5 %

discount = 100 - 87.5 %

= 12.5 %

The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the
Elina [12.6K]
If you would like to know which equation relates the weight and the dosage, you can find this using the following steps:

30-pound dog ... 1 milligram of the medicine
w pound dog ... d milligram of the medicine

30 * d = 1 * w
30 * d = w

The correct result would be 30 * d = w.

The number X of days in the summer months that a construction crew cannot work because of the weather has the probability distri
Ronch [10]

Answer:

a.)The probability of losing no more than ten days next summer is    

    0.65

b.) The probability that 8 - 12 days will be lost next summer  is 0.8

c.)  The probability there will be no days lost next summer is 0.

Step-by-step explanation:

The probability distribution for the number X of days in the summer that a construction crew cannot work because of the weather is given below:

x                    P(x)

6                   0.03

7                   0.08

8                   0.15

9                   0.2

10                  0.19

11                   0.16

12                   0.1

13                   0.07

14                   0.02

a.) To find the probability that no more than 10 days will lost next summer can be found by adding the values of probability of the days lost which are 10 days or less, that is to say we can write

 

p( x ≤ 10 )  = p(x=6) + p(x =7) + p(x=8) + p(x=9) + p(x=10)

                = 0.03     + 0.08    + 0.15     + 0.2     + 0.19

                = 0.65

b.) To find the probability that 8 to 12 days will be lost next summer will be given by taking into account and adding the probabilities starting form the probability when 8 days are lost to the probability when 12 days are lost

   p( 8 ≤ x ≤ 12)  = p(x=8) + p(x=9) + p(x=10) + p(x=11) + p(x=12)

                          = 0.15 +    0.2     + 0.19    +   0.16  + 0.1

                          = 0.8

c.) The probability that no days will be lost next summer will be given by

    = 1 - ( p(x=6) + p(x=7) +  p(x=8) + p(x=9) + p(10) + p(11) + p(12))

    = 1 -  1

    = 0  

   The probability that will be no days lost next summer is zero. We can conclude that there will be some days lost next summer.
