The probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from. This can be obtained by finding the total number of all possible three-topping pizzas (3 distinct toppings) using combination formula and finding the probability.

Given that there are 16 toppings,

the total number of all possible three-topping pizzas,

ⁿCₓ = [tex]\frac{n!}{x!(n-x)!}[/tex] = 16!/[3!(16-3)!] = 16!/[3!(13)!] = 14×15×16/3×2 =560

Probability of choosing pizza topped with ham, artichoke hearts, and pepperoni,

P(ham, artichoke hearts, pepperoni) = 1/560

Hence the probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from.

Answer: x-y

Step-by-step explanation:

If x>y, then [tex]x-y > 0[/tex].

So, [tex]|x-y|=x-y[/tex]

The solution of the expression  |x-y| if x>y without using absolute value notation is  (x - y).

A collection of constants, variables or numbers connected using one or more arithmetic operator is called an expression

Example = 4y, 3x+4

The absolute value of any number or expression is always positive.

An expression that is either less than or greater than is called as inequality.

Given expression,  |x-y| and the given inequality is x>y.

When x is greater than y, the difference between x and y is already positive.

So, the expression will be (x-y).

So, if x > y, then |x - y| = (x - y).

r = 36 ÷ 2 = 18

  Equation of circle :

      x² + y² = 18²

       x² + y² = 324

Option d.

2) Find the discriminant D.

 If  D > 0, then the quadratic equation has two distinct real roots.

  If  D= 0, then the quadratic equation has two identical real roots.

  If  D < 0, then the quadratic equation has no real roots.

  D = b² - 4ac

 x² - 6x + 9 = 0

a = 1  ; b = -6 ; c = 9

D = (-6)² - 4*1*9

Answer:

[tex]\frac{1}{7w^{2} }[/tex]

Step-by-step explanation:

The expression can be simplified only if you take the same quantity out of both the top and bottom.

You can simplify the numbers by taking a factor of 3 out of the expression.

The numerator changes to 1 (because 3 / 3 = 1) and the denominator changes to 7 (because 21 / 3 = 7).

The variables can be eliminated through subtraction. The numerator variable is completely removed because you can subtract w³ from w⁵. This makes the denominator w² (because w⁵ - w³ = w²).

The equation of a circle whose centre ([tex]-5,-2[/tex]) and radius [tex]2[/tex] is [tex]x^{2}+y^{2}+10x+4y+25=0[/tex]

What is equation of a circle?

A circle is a closed curve drawn from a fixed point called centre of the circle. The distance between the centre of the circle and the arc of the circle is called the radius of the circle.

Answer:

Step-by-step explanation:

So, we’re probably looking at a n9-m0 cusp, since adding 0 to a number gives a sum lower than adding 9 to a slightly smaller number, something that isn’t true elsewhere in the cycle.

We need a n9 where the sum n+9 is divisible by 3. 9 is divisible by 3 already, so n must be divisible by 3 as well. So, it’s 0, 3, 6, or 9.

Taking as the most likely 3 (because a 39 year old is more likely than a 9 year old, 69 year old, or 99 year old to have a child who doesn’t already know their father’s age) we’ll try 39, 40. 3+9=12, 4+0=4, 12/3=4, this is a possible solution.

Do the others work?

0+9=9, 1+0=1, 9/4=/=1

6+9=15, 7+0=7, 15/4=/=7

9+9=18, 1+0+0=1, 18/4=/=1

1+2+9=12, 1+3+0=4, 12/3=4

there are at least two possibles. the father was correct, the father cannot determine his age from what she has been told, she must guess. From what she knows of him, is it more likely that he’s 39, or 129, or even older?

The expected cost to Palmetto Insurance Company for each year Miranda has the policy is illustrated.

Term policy amount = $50000

x (age) 50 51 52 53 54

p (death) 0.0032 0.0035 0.0038 0.0041 0.0044

1. Expected cost to Palmetto Insurance Company for each year Miranda has the policy

= P(death for a given year)*term policy amount

Thus, when x = 50

Expected cost = P(x) * 50000 = 0.0032*50000 = $160

Thus, when x = 50

Expected cost = P(x) * 50000 = 0.0032*50000 = $160

Thus, when x = 51

Expected cost = P(x) * 50000 = 0.0035*50000 = $175

Thus, when x = 52

Expected cost = P(x) * 50000 = 0.0038*50000 = $190

Thus, when x = 53

Expected cost = P(x) * 50000 = 0.0041*50000 = $205

Thus, when x = 54

Expected cost = P(x) * 50000 = 0.0044*50000 = $220

Thus, the table will become

x (age) 50 51 52 53 54

p (death) 0.0032 0.0035 0.0038 0.0041 0.0044

Expected cost 160 175 190 205 220

2) For company to make $500 profit

They should charge $500 more than their expected cost

= $(500 + 160 + 175 + 190 + 205 + 220)

= $1450

Thus, they need to charge $1450 overall or (1450/5 = $290 per year)

The length of the radius of the circle is 4.9cm.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Calculation for the length of the radius of the circle-

In order to overcome this issue, we must first translate the angle from radians to degrees.

The central angle of circle is 7/6π rads = 210 degrees.

Length of the arc is 18 cm.

The formula of length of an arc is given as-

[tex]l_{a r c}=\frac{\theta}{360} * 2 \pi r[/tex]

Let's change the values and find the solution.

[tex]\begin{aligned}&18=\frac{210}{360} * 2 \pi r \\&18=3.663 r \\&r=\frac{18}{3.663} \\&r=4.9 \mathrm{~cm}\end{aligned}[/tex]

Ratio scale of measurement for the following variable, The weight of a group of dieters.

Ratio measurement scale of ratio variables include height, weight, and distance. The ratio scale allows for the addition, subtraction, division, and multiplication of data. Additionally, ratio scales have a "real zero," which sets them apart from interval scales. The ratio scale is used to determine weight. The ratio is identical to the interval scale, with the exception that 0 on the scale denotes the absence of anything. serval scales can depict values lower than zero and do not hold a true zero. For instance, you can gauge temperatures as low as -10 degrees Celsius. Contrarily, ratio variables are always greater than zero. Height and weight are measured starting at 0 and never below it. Because they are numbers as we typically think of them, ratio scales are the simplest to comprehend. On a ratio scale, the distance between consecutive numbers is equal, and a score of zero indicates that there is no presence of the thing being measured.

The polynomial equation x³ - 4x² - 7x + 28 = 0, has solutions -√7, √7, and 4, among which √7 and 4 are positive real solutions. Hence we have two positive real solutions. Hence, option D is the right choice.

In the question, we are asked for the number of positive real solutions for the polynomial equation, x³ - 4x² - 7x + 28 = 0.

To find the solutions, we do as follows:

x³ - 4x² - 7x + 28 = 0,

or, (x³ - 7x) - (4x² + 28) = 0 {Grouping},

or, x(x² - 7) - 4(x² - 7) = 0 {Taking common},

or, (x - 4)(x² - 7) = 0 {Grouping},

or, (x - 4)(x + √7)(x - √7) = 0 {Using the formula: [tex]a^2 - b^2 = (a+b)(a-b)[/tex]}.

By the zero-product rule, the solutions are:

x - 4 = 0, or, x = 4,

x + √7 = 0, or, x = -√7,

x - √7 = 0, or, x = √7.

Thus, the positive real solutions are 4, and √7. Hence, there are two positive real solutions.

Thus, the polynomial equation x³ - 4x² - 7x + 28 = 0, has solutions -√7, √7, and 4, among which √7 and 4 are positive real solutions. Hence we have two positive real solutions. Hence, option D is the right choice.
