"Describe the relationship between the relative frequency of the coin landing on heads and the probability of a single coin land

ing on heads. Does sample size affect this relationship?"
Mathematics
1 answer:
BigorU [14]3 years ago
4 0

Answer:

The greater the sample size, the closer the percentage.

Step-by-step explanation:

<u>Relative frequency</u>

The relative frequency of an event is the division of the number of times that an event occurs during experimental trials by the total number of trials conducted.

The percentage of the relative frequency of getting Head is usually very close to the theoretical probability of getting a Head. However, results vary for each experiment.

The sample size in this case is the number of experiments carried out. The greater the sample size, the closer the percentage of Heads will be to the theoretical probability of getting a Head.

A cube has a surface area of 486 cm2. What is the side length ?
astraxan [27]
A Cube, has all equal sides, namely, the length, width and height
are all equal to each other

so..  notice the picture added here
you have really, 6 squares, stacked up to each other at the edges

so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is x\cdot x \implies x^2

well, you have 6 of those squares, thus \bf \textit{surface area of a cube}=&#10;\begin{cases}&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)\\&#10; --------------\\&#10; x^2+x^2+x^2+x^2+x^2\\&#10;6x^2&#10;\end{cases}&#10;\\\\&#10;\textit{we know the Area is }486\ cm^2\qquad thus&#10;\\\\&#10;\textit{surface area}=6x^2\implies 486=6x^2

solve for "x", to get one side's length

Two hundred fifty one thousand and four hundred

Step-by-step explanation:

In international system commas are placed after three digits starting from the unit's place.

a) 40050017 = 40,050,017

Forty million fifty thousand and seventeen

b) 251400 = 251,400

Two hundred fifty one thousand and four hundred

Use law of sines or law of cosines to find the length of side AB Please show work !!
scoray [572]

Answer:

AB = 11.3

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}

So, we have:

\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}

Make AB the subject

AB = \frac{15}{\sin(70)} * \sin(45)

AB = \frac{15}{0.9397} *0.7071

AB = 11.3
