Nominal scales are used for labeling variables, without any quantitative value.

Ordinal the order of the values is what is significant, but the differences between each one is not really known.

Interval we know both, the order and the exact differences between the values

Ratio data they have the order, the exact value between units, and have an absolute zero

Alexa is researching a cure for the coronavirus. She needs 14 test tubes for 4 experiments. The first experiment requires 2 test

grigory [225]

Answer:

She used 4 test tubes for the last experiment

Step-by-step explanation:

Total test tubes needed = 14

Experiment 1 = 2 test tubes

Total test tubes remaining = total - used

= 14 - 2

= 12 test tubes

Remaining experiment = 4 - 1

= 3

Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining

= 12 / 3

= 4 test tubes

How many test tubes did she use for the last experiment?

She used 4 test tubes for the last experiment

Anastasy [175]

Answer:

She colored 30 yellow place value disks and 50 disks are left to color.

Step-by-step explanation:

Let total number of disks be x.

It is given that, she colored 2/6 of the disks red. She colored 1/4 of the disks yellow.

$\text{Red disks}=\dfrac{2}{6}x$

$\text{Yellow disks}=\dfrac{1}{4}x$

She colored 40 red place value disks.

$\dfrac{2}{6}x=40$

$\dfrac{1}{3}x=40$

$x=120$

It means total number of disks is 120.

$\text{Yellow disks}=\dfrac{1}{4}x=\dfrac{1}{4}(120)=30$

So, she colored 30 yellow place value disks.

Remaining disks = Total disks - Red disks - Yellow disks

$=120-30-40$

$=50$

Therefore, 50 disks are left to color.
