Newton's second law is F = ma. In this task, you will plan two controlled experiments to see how changes in force and changes in

mass affect the motion of the box in the hanging weight simulation from task 1. Because you don’t have access to special measuring devices, you’ll just use observation to compare the acceleration of the box as it moves across the table. You should change only the force or the mass, but not both, because these are controlled experiments.
estimated time to complete: 20 minutes

Part A
Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.

  • Midpoint Formula: (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Given our two points, (-3,9) and (-1,4), we can apply them to the midpoint formula and solve for it as such:

(\frac{(-3)+(-1)}{2}, \frac{9+4}{2})\\\\(\frac{(-4)}{2}, \frac{13}{2}) \\\\(-2,6.5)

<u>Your midpoint is (-2,6.5)</u>

Current estimates are that about 25% of all deaths are due to cancer, and of the deaths that are due to cancer, 30% are attribut
Aliun [14]

Answer:

(a) P (T|C) = 0.30, P (T|D) = 0.40 and P (O|C) = 0.30

(b) The probability that a death is due to cancer and tobacco is 0.075.

Step-by-step explanation:

Let us denote the events as follows:

C = death is due to cancer

T = cause of cancer was tobacco

D = cause of cancer was diet

O = cause of cancer was other issue

The provided information is:

P (C) = 0.25

P (T|C) = 0.30

P (T|D) = 0.40

P (O|C) = 0.30

(a)

The conditional probability of an event <em>A</em> given that another event <em>B</em> has already occurred is denoted by, P (A|B).

This implies that the occurrence of event B is affected by the previously occurred event A.

Causes of cancer are tobacco, diet and other issues. If a death is caused by cancer then the probability that the cause of cancer was tobacco or diet or something else are conditional events.

The conditional probabilities are:

0.40 for diet, 0.30 for tobacco and 0.30 for other causes.

(b)

Conditional probability formula is:

P (A|B)=\frac{P(A\cap B)}{P(B)}

Compute the probability that a death is due to cancer and tobacco as follows:

P (T|C)=\frac{P(C\cap T)}{P(C)}\\P(C\cap T)=P(T|C)\times P(C)\\=0.30\times0.25\\=0.075

Thus, the probability that a death is due to cancer and tobacco is 0.075.

An architect designs a rectangular flower garden such that the width is exactly​ two-thirds of the length. if 370 feet of antiqu
Korolek [52]

Answer:

111 Feet

Step-by-step explanation:

The feet of antique picket fencing are to be used to enclose the​ garden is equivalent to the perimeter of the flower garden.

The perimeter P of a rectangle  whose length is L and width is W is given as

P = 2( L + W)

Given that the width is exactly​ two-thirds of the length

then, W = 2/3 L and P = 370 feet

L = 3/2 W = 1.5W

370 = 2 ( 1.5W + W)

370 = 5W

W = 370/5

= 74 Feet

L = 1.5W

= 1.5 * 74

= 111 Feet

The shaded portion of the bar model in Part A shows 38. What percent is equivalent to 38? Enter the correct answer in the box.
nordsb [41]

Question:

The shaded portion of the bar model in Part A shows 3/8. What percent is equivalent to 3/8? Enter the correct answer in the box.

Answer:

The equivalent is 37.5%

Step-by-step explanation:

Given

\frac{3}{8}

Required

The equivalent

<em>The model is not shown, but the question can still be solved.</em>

We have:

\frac{3}{8}

Multiply by 100%

\frac{3}{8} = \frac{3}{8} * 100\%

\frac{3}{8} = 0.375 * 100\%

\frac{3}{8} = 37.5\%
