Answer:

x = 2

Step-by-step explanation:

x + 3 = -x + 7

Add x to each side

x+x + 3 = -x+x + 7

2x+3 = 7

Subtract 3 from each side

2x = 7-3

2x = 4

Divide by 2

2x/2 = 4/2

x = 2

Before flipping a fair coin, Sunil assesses that he has a 50% chance of obtaining tails. Subjective probability Empirical probab
ASHA 777 [7]

Answer:

a) Classical

b) Subjective

c) Empirical

Step-by-step explanation:

a) Classical probability: In classical probability, all the events have the same probability. When flipping a coin, the probability of getting tails is the same as the probability of getting tails, therefore, the probability of both events is 50%.

b) Subjective probability: Subjective probability is derived from a personal judgement based on previous experiences. In this case, John would be calculating his probability of receiving A's based on his previous semesters.

c) Empirical probability: is the ratio between the number of outcomes a scenario happens and the total of trials in an ACTUAL EXPERIMENT. In this case, the reporter would be calculating this probability based on his previous experiences attending actual conferences.

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choo
andre [41]

The time it takes between when the rock was dropped and when it landed is 1.33 seconds.

<h3>What is the time it takes for the rock to land?</h3>

The time it takes the rock to land on the ground from where it is dropped can be determined by using the function given.

The height of the function when it hits the ground will be zero, so the function can be written as:

\mathbf{h(t) =36t^2 -64}

\mathbf{0 =36t^2 -64}

64 = 36t²

\mathbf{t^2 = \dfrac{64}{36}}

t² =1.778

t = \sqrt{1.778}

t = 1.333 seconds

What is the area of the figure? <br> /Users/macuser/Downloads/MS_IMB-1401012-1100604.jpg
xeze [42]
Given:
Shapes: Trapezoid and Triangle.

Trapezoid: Upper base = 14mm ; lower base = 18mm
Triangle: base = 18mm ; height = 12mm
Total height of the figure is 17 mm

Area of a trapezoid = (upper base + lower base)/2  * height
A = (14mm+18mm)/2  * (17mm-12mm)
A = 32mm/2 * 5mm
A = 16mm * 5mm
A = 80 mm²

Area of a triangle = (height * base) ÷ 2
A = (12mm * 18mm) ÷ 2
A = 216mm² ÷ 2
A = 108 mm²

Total area of the figure = 80 mm² + 108 mm² = 188mm²
