A candle maker has 4 1/2 pounds of clear wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pi
prisoha [69]

Answer:

a)  10  pieces of  2/3 pound  can be made.

b) 0.54 pounds of wax is left over.

Step-by-step explanation:

Total amount of clear wax available =  4\frac{1}{2}  = \frac{9}{2} pounds

So, the maker has in total 4.5 pounds of wax

Now, The weight of each piece = \frac{2}{3}  = 0.66  pounds

To find the number of pieces that can be made out of 4.5 pounds of wax,

let that number = n

So, n = \frac{\textrm{Total weight of the clear wax}}{\textrm{Weight of each wax}}

or, n = n = \frac{4.5}{0.66}  = 6.81

So, nearly 6 pieces can be made completely out of the clear wax

Left over amount of wax  = Total weight -  Weights of the pieces made

                                            =  4.5- 6(0.66)

                                            = 0.54 pounds

Hence, 0.54 pounds of wax is left over

This table shows the number of customers who have come in to Trent’s Hobby Shop each day since he opened the doors.
Alona [7]

Since both the input and the output assume only integer values, the function is classified as discrete.

<h3>What are continuous and discrete variables?</h3>

  • Continuous variables: Can assume decimal values, hence they are represented by rational numbers.
  • Discrete variables: Assume only countable values, such as 1, 2, 3, …, hence they are represented by whole numbers, or even integers if it can be negative.

In this problem, all values on the table assume only integer values, hence the function is classified as discrete.

Which of the following about the normal distribution is not​ true?
Lostsunrise [7]

Answer:

Normal distribution is a Continuous distribution.

Step-by-step explanation:

Normal Distribution:

The following information is true about normal distribution.

  • ​Theoretically, the​ mean, median, and mode are the same.
  • Its parameters are the​ mean, mu​, and standard​ deviation, sigma.
  • About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.

But normal distribution is not a discrete distribution. It is a continuous distribution.

  • The normal distribution is a continuous probability distribution. This has several implications for probability.
  • The probability that a normal random variable X equals any particular value is 0.
