Which variable is discrete

Mathematics
1 answer:
Aloiza [94]3 years ago
7 0

Answer:

C. The number of runners in a race

Step-by-step explanation:

Variables can be widely be classified as either discrete or continuous. A continuous variable is a variable which can take on any value within its domain. A continuous variable can take on fraction of units. Examples of continuous variables include;

time to finish a race - it can be 10.5 sec or 35.56 sec

temperature at start of race - the temperature could be 25.5 K, or 45.57 K

length of race in kilometers - the length could be 20 km, 22.45 km or 38.8 km

All the above variables can be measured in fraction of units and are thus continuous in nature.

On the other hand, a variable is said to be discrete if it can take on only integer values. An example in this case would be ;

the number of runners in a race. We can only have, 10, 45, 600, 565 and so on runners but never a fraction of a runner.

Nadya [2.5K]

9514 1404 393

Answer:

  AD= 8

  DC= 15

  Angle a= 112°

  Angle b= 68°

  Angle c= 112°

Step-by-step explanation:

We have to assume the figure is a parallelogram.

Opposite sides of a parallelogram are congruent, so ...

  BC = AD = 8

  AB = DC = 15

Opposite angles are congruent, and adjacent angles are supplementary.

  180° - ∠D = Angle a = Angle c = 112°

  ∠D = Angle b = 68°

The variable z is inversely proportional to x. When x is 19, z has the value 0.10526315789474. What is the value of z when x= 28
telo118 [61]

When two variables are inversely proportional the relation between them can be written as:

z=\frac{k}{x}

Here, k is the constant of proportionality and is always equal to the product of the two variables. So using the given values of z and x, we can find k first.

k=zx\\ \\  k=0.10526315789474(19)\\ \\  k=2

The constant of proportionality for the given inverse proportion comes out to be 2. Using the value of k in the equation, we get:

z=\frac{2}{x}

We have to find the value of z when x=28. So replacing x by 28, we get:

z=\frac{2}{28}\\  \\  z=0.07142857143

Thus, rounding of to nearest thousand the value of z comes out to be 0.071 if x is equal to 28.

Explain two different squares that can be used using the number 9?
Iteru [2.4K]

Answer:

Please the explanation section.

Step-by-step explanation:

There will be 2 squares. Those can be 9. Those are:

One square can be a 3 by 3 square, meaning each side will be  3 units. The area for this will be 9.

Another one is the square can be a 9 by 9 square, meaning each side will be 9 units. The area for this will bebe 81.

Peanuts are priced at 3.38 per pound. Derek buys a sack of peanuts for 15.82. Which measurement is a reasonable estimate of the
Rashid [163]

Given :

Price per pound of peanuts is, P = $3.38 .

Derek buys a sack of peanuts for $15.82.

To Find :

The weight of the peanuts that are in the sack.

Solution :

Let, weight of peanuts that are in the sack are x.

So, x = \dfrac{15.82}{3.38}\\\\x = 4.68\ pounds

Therefore, number of pounds in the sack is 4.68 pounds.
