Answer:2/5
Step-by-step explanation:
duration of an experiment?
This group does not get any treatment, but rather they get a placebo instead. For instance, in a medical experiment testing a new drug, the control group would get a sugar pill (the people in this group think they are getting the actual drug itself, and not a fake pill).
In contrast, the experimental group is the group that receives the actual treatment.
To find the height of the cone, we can use the formula for the lateral area of a cone and the Pythagorean theorem. The height of the cone is approximately 11.3 cm.
To find the height of the cone, we need to use the formula for the lateral area of a cone, which is given by:
Lateral Area = πrL
where r is the radius of the base and L is the slant height of the cone. Since the diameter of the cone is 10.2 cm, the radius is half of that, which is 5.1 cm. We can rearrange the formula and solve for L:
L = Lateral Area / (πr) = 198.6 cm² / (3.14 x 5.1 cm) ≈ 12.4 cm
Now that we have the slant height, we can use the Pythagorean theorem to find the height of the cone. The height (h) and the slant height (L) form a right triangle with the radius (r) as the hypotenuse. Applying the Pythagorean theorem:
h² + r² = L² = h² + (5.1 cm)² = (12.4 cm)²
From this equation, we can solve for h:
h² = (12.4 cm)² - (5.1 cm)²
After evaluating this equation, we find that h ≈ 11.3 cm, so the height of the cone is approximately 11.3 cm to the nearest tenth of a centimetre.

The notion of a unit rate is how much will happen in a unit of measurement. The question indicates there are 30 hotdogs in a total of 5 minutes, averaging 6 hotdogs per minute, or .1 hotdogs per second. This is done by dividing the total into equal 'chunks' of that unit of time.The question therefore does not make sense to "not include units".
