A study shows that 78​% of the population of all calculus students consider calculus an exciting subject. Suppose 20 students ar
alexdok [17]

Answer:

0.046145 = 4.6145%

Step-by-step explanation:

We need to find the probability of 19 or 20 (all) students considering calculus to be an exciting subject, so first we find the probability for 19 students, then for 20 students, and we sum these probabilities.

The probability of the student NOT considering calculus to be an exciting subject is 1 - 0.78 = 0.22

For 19 students, we also have to calculate a combination of 20 choose 19, as these 19 students can be in different "position" among the 20 students, so:

C(20,19) = 20!/19! = 20

Probability of 19 students considering calculus to be an exciting subject:

C(20,19) * 0.78^19 * 0.22^1 = 0.039196756

Probability of 20 students considering calculus to be an exciting subject:

C(20,20) * 0.78^20 = 1 * 0.78^20 = 0.006948516

The final probability is:

0.039196756 + 0.006948516 = 0.046145272 = 4.6145272%

Rounding to six decimal places: 0.046145 = 4.6145%

If the angle is preserved, which describes the effect of moving the plane closer to the cone's vertex? Check all that apply.
Sholpan [36]

Let's go though the choices.

Major axis will get shorter.  TRUE, CHECK ME

As the plane moves closer to the vertex the ellipse stays the same shape but shrinks.

Ellipse will become a circle.  FALSE

As long as the plane is tilted, the ellipse can't be a circle.

Ellipse will degenerate to a point.  TRUE, CHECK ME

Eventually the plane gets to the vertex, at which point (ha!) we have a single point.

Nappes?  Is that a word?   FALSE

The plane needs a steeper angle, steeper than the generators, before it can pass through both halves.

The generators are the lines through the vertex that form the cone.  The plane isn't steep enough to hold any of them. FALSE
