(1) When Emma is standing at the top of the mountain, the energy encountered is potential energy.

(2) When Emma is jumping down from the mountain top, the energy encountered is both kinetic energy and potential energy.

(3) The energy creating the tensional force on the rope at Emma’s lowest position is elastic potential energy.

(4) When Emmas is bouncing back, he will encounter both kinetic energy and potential energy.

<h3>Conservation of energy</h3>

The energy encountered by Emma and the rope at each point is determined from the principle of conservation of mechanical energy.

<h3>1.0 Emma standing on top of mountain </h3>

When Emma is standing at the top of the mountain, the energy encountered is potential energy this is due to his position above the ground level.

P.E = mgh

<h3>2.0 Emma jumping down from mountain top</h3>

When Emma is jumping down from the mountain top, the energy encountered is both kinetic energy and potential energy. This is as a result of his position above the ground level and his motion downwards.

M.A = K.E + P.E

<h3>3.0 Tension in rope at Emma’s lowest position</h3>

The energy creating the tensional force on the rope at Emma’s lowest position is elastic potential energy.

U = ¹/₂kx²

<h3> 4.0 Emma bouncing back</h3>

When Emmas is bouncing back, he will encounter both kinetic energy and potential energy due to his motion and position above the ground.

Given: lines l and m are parallel, and line t is a transversal.

angle pair result/justification

1 and 2 are equal (vertical angles)

6 and 8 are equal (corresponding angles)

1 and 4 are equal (alternate exterior angles)

4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)

Note:

alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.

If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)

If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)

manufacturing company produces digital cameras and claim that their products maybe 3% defective. A video company, when purchasin

alexdok [17]

Answer:

P(X>17) = 0.979

Step-by-step explanation:

Probability that a camera is defective, p = 3% = 3/100 = 0.03

20 cameras were randomly selected.i.e sample size, n = 20

Probability that a camera is working, q = 1 - p = 1 - 0.03 = 0.97

Probability that more than 17 cameras are working P ( X > 17)

This is a binomial distribution P(X = r) $nCr q^{r} p^{n-r}$

$nCr = \frac{n!}{(n-r)!r!}$

P(X>17) = P(X=18) + P(X=19) + P(X=20)

P(X=18) = $20C18 * 0.97^{18} * 0.03^{20-18}$

P(X=18) = $20C18 * 0.97^{18} * 0.03^{2}$

P(X=18) = 0.0988

P(X=19) = $20C19 * 0.97^{19} * 0.03^{20-19}$

P(X=19) = $20C19 * 0.97^{19} * 0.03^{1}$

P(X=19) = 0.3364

P(X=20) = $20C20 * 0.97^{20} * 0.03^{20-20}$

P(X=20) = $20C20 * 0.97^{20} * 0.03^{0}$

P(X=20) = 0.5438

P(X>17) = 0.0988 + 0.3364 + 0.5438

P(X>17) = 0.979

The probability that there are more than 17 working cameras should be 0.979 for the company to accept the whole batch
