if die us rolled once what is the probability of getting a number that is not 3

Answers

Answer 1

The rule of probability is

[tex]P(A)=\frac{A}{\text{total}}[/tex]

Since the die has 6 numbers, then

The total = 6

Since there are 5 numbers without 3, then

A = 5

Substitute them in the rule above

[tex]P(\text{not}3)=\frac{5}{6}[/tex]

The answer is 5/6

Find the first four terms of the binomial series for the function (1+2x)^1/2

Answers

The first four terms of the binomial series are  1, x, - x²/2 and - 1/32x³ respectively.

The binomial provided to us is [tex](1+2x)^{1/2}[/tex]

To find out the first four terms of the binomial, we shall first extend the standard binomial (1+x)^n.

(1+x)^n = 1 + nx + [n(n - 1)/2!] x² +  [n(n - 1)(n - 2)/3!] x³ +...

As we can see here,

The value of x = 2x,

The value of n = 1/2.

We get,

(1+2x)^1/2 = 1 + 1/2(2x) + [1/2(1/2-1)/2!]x² + [1/2(1/2-1)(1/2-2)/3!]x³ +

(1+2x)^1/2 = 1 + x  - x²/2 - 9/4x³ + .....

From the expansion, we can see,

First term = 1

Second term = x

Third term = -x²/2

Fourth term = -1/32x³.

Answers

The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.

What is a number line?

A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

Next, we would solve the given inequality as follows:

−0.4b + 2.4 < 5.6

Subtracting 2.4 from both sides, we have:

−0.4b + 2.4 - 2.4 < 5.6 - 2.4

−0.4b < 5.6 - 2.4

−0.4b < 3.2

Dividing both sides by -0.4, we have:

b < -3.2/0.4

b < -8

In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.

The total ratio of the drive is 9.58:1.

What are ratios?A relationship between two quantities that are typically stated as the product of their respective quotients is known as a ratio.The ratio formula is given as a:b = a/b for any two quantities, let's say a and b.

Given ratios of the three separate stages of a gear reduction drive are 3:1,2.38:1 and 4.2:1.

To find the total ratio of the drive we have to add the respective ratios.

When the denominator of the ratios are same, as in this case we just have to add the numerators to obtain the result.

Total ratio of the drive = 3:1 + 2.38:1 + 4.2:1 = 9.58:1

The fraction of the man's income left is 3/20.

What are fractions?In mathematics, a fraction is represented by a numerical value that represents a portion of an entire. A fraction is a piece or section of a whole, where the whole can be any number, a particular value, or an object.

Let's assume the monthly income of the man is x.

Income spend on children's school fees =  [tex]\frac{1}{4} x[/tex]

Income spend on home affairs =  [tex]\frac{3}{5} x[/tex]

The fraction of his income left with the man is,

Total income - Total expenditure

=  [tex]x-(\frac{1}{4} x + \frac{3}{5} x)[/tex]

A trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).
a. Dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.
b. Is the dilation a reduction or an enlargement? Explain your reasoning.

Answers

a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)

b) Dilation is reduction.

In this question, we have been given a trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).

a. We need to dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.

The scale factor is 1/3

so, the coordinates of the image would be,

F' = 1/3 (-9, 6)

   = (-3, 2),

G' = 1/3(-6, 9)

    = (-2, 3),

H' = 1/3 (−3, 9)

    = (-1, 3),

and I' = 1/3 (0, 6)

         = (0, 2)

b. We know that a dilation is a geometric transformation that either enlarges or reduces a figure in size.

As we know, if the scale factor is between 0 to 1 then the image is reduction and if the scale factor is greater than 1 then the image is enlargement.

Here, scale factor is 1/3 which is 0 < 1/3 < 1

So, in this case the dilation is reduction.

Therefore, a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)

b) Dilation is reduction.

Step-by-step explanation:

You want to determine a three-digit combination based on clues about which digits are right and/or correctly placed.

Clue 1

This tells you one of digits 1, 2, or 7 is correct and correctly placed.

Clue 2 tells you that digit is not 1. Clue 4 tells you that digit is not 2.

  7 is correctly placed as the 3rd digit

Clue 2

We already know that 1 is not the correct digit. This means 3 must be the first digit, or 8 must be the first or second digit.

Clue 3

We already know that 7 is a correct digit, properly placed as the 3rd digit. Since 1 is not a correct digit, 9 must be a correct digit, properly placed as the 1st digit.

  9 is correctly placed as the 1st digit

Combining this fact with Clue 2 means ...

  8 is correctly placed as the 2nd digit

Where "n" is the number of trials, "x" is the number of successes desired, and "p" is the probability of getting a success in one trial.

In this case you know that:

[tex]P(x=4)=(\frac{15!}{(15-4)!4!})(0.4)^4(1-0.4)^{15-4}[/tex][tex]P(x=4)=(\frac{15!}{(11)!4!})(0.4)^4(0.6)^{11}[/tex][tex]P(x=4)\approx0.1268[/tex]

This is:

[tex]P(x\leq3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]

Therefore, using the formula, set up:

How to determine the three element subsets?

In order to determine the three-element subsets from the given set {1, 2, 3, 4, 5}, we would have to calculate the number of ways to choose the three (3) elements by applying a mathematical model referred to as combination.

Mathematically, combination is given by this mathematical equation:

[tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex]

Where:

n is the number of elements.r is the number of times of choosing elements.

Substituting the given parameters into the formula, we have;

Number of ways = ⁵C₃

Number of ways = 5!/(3! × (5 - 3)!)

Number of ways = 5!/(3! × 2!)

Number of ways = [5 × 4 × 3 × 2 × 1]/[3 × 2 × 2 × 1]

Number of ways = 120/12

Number of ways = 10 ways.
