Mathematics
1 answer:
Nitella [24]3 years ago

Answers:

  1. Discrete
  2. Continuous
  3. Discrete
  4. Continuous

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

Explanations:

  1. This is discrete because we can't have half a basketball, or any non-whole decimal value to represent the number of basketballs. We can only consider positive whole numbers {1,2,3,4,...}. A discrete set like this has gaps between items. In other words, the midpoint of 2 and 3 (the value 2.5) isn't a valid number of basketballs.
  2. This is continuous because time values are continuous. We can take any two different markers in time, and find a midpoint between them. For example, the midpoint of 5 minutes and 17 minutes is 11 minutes since (5+17)/2 = 22/2 = 11. Continuous sets like this do not have any gaps between items. We can consider this to be densely packed.
  3. This is the same as problem 1, so we have another discrete function. You either score a bullseye or you don't. We can't score half a bullseye. The only possible values are {1,2,3,4,...}
  4. This is similar to problem 2. This function is continuous. Pick any two different positive real numbers to represent the amount of gallons of water. You will always be able to find a midpoint between those values (eg: we can have half a gallon) and such a measurement makes sense.

So in short, always try to ask the question: Can I pick two different values, compute the midpoint, and have that midpoint make sense? If so, then you're dealing with a continuous variable. Otherwise, the data is discrete.

Answer: 5/4x

Step-by-step explanation:

To solve this you'll need to use the slope formula which is

Y2 - Y1 over

X1 - X2

You already have two points so that's what we'll use.

(4, 7) (12, 17)

17 - 7

12 - 4  = 10/8

10/8 can be simplified further to 5/4

Raj’s bathtub is clogged and is draining at a rate of 1. 5 gallons of water per minute. The table shows that the amount of water
Morgarella [4.7K]

Answer:

Draining rate is at 1.5 gallons per minute

That would be y = 1.5g / x.

From the function or the equation, here is the answer.

The range would be all real numbers such that 0 ≤ y ≤ 40.

Eighth grade math. Please leave explanation!
kolbaska11 [484]

First multiply both sides by 7

Your equation now looks like this:

x-28=0

Now move the constant to the other side causing it to change signs

The negative now becomes a positive

x=28

Now you are left with your answer:

x=28

Hope this helps! :3

For the equation, complete the solution.<br> 19x = 15y<br> (x, y) = ( x ,-3)
nexus9112 [7]

Answer:

( - \frac{45}{19}, - 3)

Step-by-step explanation:

Given

19x = 15y and (x, - 3 ), that is y = - 3

Substitute y = - 3 into the equation

19x = 15(- 3) = - 45 ( divide both sides by 19 )

x = - \frac{45}{19}
