Answer:

Step-by-step explanation:







The radius of the cylinder is 2.92 cm
<u>Explanation:</u>
Given:
Volume of cylinder, V = 193 cm³
Height of the cylinder, h = 7.2 cm
Radius of the cylinder, r = ?
We know:
Volume of cylinder = πr²h
On substituting the value we get:

Therefore, the radius of the cylinder is 2.92 cm
The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."
<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16
18 times
Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.

Then, you divide that from 72.

So, the number of times I would expect the outcome to be greater than 4 is 18.
