The experimental probability that all three of the coins will be head is 1 / 10.

The theoretical probability that all three of the coins will be head is 1/8.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

Experimental probability is based on the result of an experiment that has been carried out multiples times.

Experimental probability = number of times all heads is gotten / total number of tosses

5/50 = 1/10

Theoretical probability = number of times all heads can be gotten / total number of possible outcomes

1/8

Write the phrase as an expression the quotient of 22 and a number [tex]a[/tex].The quotient of 22 and  [tex]a[/tex]  number = 22/[tex]a[/tex]

Given that

number = 22

quotient =   [tex]a[/tex]

To find

The mathematical equation or relation between quotient of 22 and a number [tex]a[/tex].

So according the question

We have

quotient = 22

divisor =   [tex]a[/tex]

For finding the relation between given quotient and divisor, let's firstly know about Dividend, Divisor, Quotient and Remainder,

In Mathematics, the dividend is the value that is divided by another value to get the result. The dividend is the base of any division method.

An integer that divides another integer to obtain a result is called a divisor. The result of this division, or quotient, is the dividend, which is the original number that was divided.

Quotient = Dividend ÷ Divisor

When we divide one number by another, the result is a quotient. As an illustration, when we divide 6 by 3, we obtain the answer 2, which is the quotient. A decimal or an integer can both be used as the quotient. When dividing exactly, as when 10 ÷5 = 2, the quotient is an integer, whereas when dividing roughly, as when 12÷ 5 = 2.4, the quotient is a decimal. Although a quotient can be greater than the divisor, it will never be greater than the dividend.

The value remaining after division is known as the Remainder. After division, we are left with a value if a number (dividend) cannot be divided entirely by another number (divisor). This value is called the remainder.

Now, from question  

We have a quotient of 22 that is [tex]a[/tex].

So, 22 fully divided by [tex]a[/tex].

In mathematical form,

                        = 22/[tex]a[/tex]

The quotient of 22 and [tex]a[/tex]  number = 22/[tex]a[/tex]

Answer: 27

Step-by-step explanation:

This geometric progression has 5 terms

This is a geometric progression or geometric series whose sum of n terms is given by the formula

Sn = a[([tex]r^{n\[/tex] – 1)/(r – 1)]

Where Sn is sum of n terms of geometric progression, a is the first term of the series , r is the common ratio

Here we are required to find the number of terms in the geometric progression whose first term is -3 and common ratio is 6

-4665 = -3 [( [tex]6^{n}[/tex]-1)/(6-1)

1555=( [tex]6^{n}[/tex]-1)/5

7775= [tex]6^{n}[/tex]- 1

7776 = [tex]6^{n}[/tex]

[tex]6^{5}[/tex] = [tex]6^{n}[/tex]

So, n=5

Step-by-step explanation:

Using it's concepts, we have that:

A function has the following format: y = f(x).

In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.

That is, the input of the function is the independent variable and the output is the dependent variable.

By unitary method we can say that it is better to buy the 4 inch radius pizza for $3.

According to the given question.

The price of 4 inch radius pizza = $3

And, the price of 8 inch radius pizza = $14

As we know that, the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Therefore, by unitary method.

Cost of 1inch radius pizza, when the price of 4 inch radius pizza is $3

= 3/4

= $0.75

And the cost of 1 inch radius pizza, when the price of 8 inch radius pizza is $ 14

= 14/8

= $ 1.75

Hence, by unitary method we can say that it is better to buy the 4 inch radius pizza for $3.

Sample Standard deviation = 5.82

The dispersion of your data's middle quartile is measured by the interquartile range (IQR). It is the range for your sample's middle 50%. Assess geographical variability where the majority of your numbers are by using the IQR. Larger numbers suggest a wider dispersion of your data's center region.

According to the given data:

Vectors is a quantity that has both magnitude and direction as well. A vector that has 1 magnitude is called unit vector. Unit vector is represented by the symbol '^'.

To find a Unit vector we divide the vector by its magnitude.

First find the slope of the tangent line, slope of a tangent line for a point f(x) is given by f'(x). Hence at point (π/6,1) where x = π/6, the slope of the tangent line is :

[tex]f(x)=2sinx\\f'(x)=2cosx\\f'(\pi /6)=2cos(\pi /6)=2.\frac{\sqrt{3} }{2}=\sqrt{3}[/tex]

The slope of the tangent line at this point is [tex]m=\sqrt{3}[/tex]

Finding a unit vector parallel to the tangent line. since slope is the ratio y and x then we can set an arbitrary vector with slope 4 by letting x=1 and y = √3 or v=[1,√3]. this vector has slope √3 and this is parallel to the tangent line, However this is not unit vector because its magnitude is not equal to 1 so we can divide this vector by its magnitude to find the unit vector.

[tex]u_v=\frac{v}{|v|} =\frac{1 \sqrt{3} }{\sqrt{1^{2}+(\sqrt{3})^2 } } \\=\frac{1}{\sqrt{4} } ,\frac{\sqrt{3} }{\sqrt{4} } =\frac{1}{2}, \frac{\sqrt{3} }{2} =[\frac{1}{2},\frac{\sqrt{3} }{2} ][/tex]

If a line has slope of m then all lines perpendicular of it will have a slope of  -1/m

So we are looking for a unit vector of slope of -1/√3

Using the same logic we have unit vector that are perpendicular to the tangent line are [tex][\frac{\sqrt{3} }{2},-\frac{1}{2} ][/tex]

B. The integer representing the altitude after passing the storm is 30,000

A. We are given that the initial altitude of the plane was 30,000 ft. The plane flew at at altitude of 38,000 feet

Change of altitude = final altitude - initial altitude

Change of altitude = 38,000 - 30,000 = 8,000 ft

Therefore, the integer representing the change of altitude to avoid the storm is 8,000

B. After the storm:
