The probability helps us to know the chances of an event occurring. The probability of winning a small prize in the carnival is 35.714%.

The probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that there is a total of 56 ducks floating in the pond, out of which 20 ducks are marked as small-prize winners. Therefore, the probability of winning a small price can be written as:

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\\rm Probability=\dfrac{\text{Nnmber of small price ducks}}{\text{Total number of ducks}}\\\\\\Probability = \dfrac{20}{56} = 0.35714 = 35.714\%[/tex]

Hence, the probability of winning a small prize in the carnival is 35.714%.

To have the same number of pennies in both sides, we should add 6 pennies, so Charlotte is correct.

We want to have the same number of pennies on both sides, on one side we have 23 pennies, and in the other 17. So we will add x pennies to the last side, such that we get:

23 = 17 + x

This is a linear equation. To solve it, we need to isolate the variable x, we can do that by subtracting 17 in both sides:

23 - 17 = 17 + x - 17

6 = x

This means that the solution is 6, so we should add 6 pennies, meaning that Charlotte is correct.

2(6-2x) - 2x = 2(5+x)-4

turns into

2(6-2[3/4]) - 2[3/4] = 2(5+[3/4]) -4

Hope this helps!

Answer:

Step-by-step explanation:

In the question we're given with an equation i.e.,

And we are asked to find the value of x .

Solution :

[tex] \longmapsto \: 2 ( 6 - 2x ) - 2x = 2 ( 5 + x ) - 4 [/tex]

Step 1 : Solving parenthesis by multiplying it with 2 on both the sides :

[tex] \longmapsto \: 12 - \bold{4x} - \bold{2x} = \bold{10} + 2x - \bold{4}[/tex]

Step 2 : Adding like terms on left hand side and subtracting like terms on right hand side :

[tex] \longmapsto \: 12 - 6x = 2x + 6[/tex]

Step 3 : Transposing 12 to right hand side and 2x to left hand side :

[tex] \longmapsto \: -2x - 6x = 6 - 12[/tex]

On further calculations we get :

[tex] \longmapsto \: \cancel{ - }8x = \cancel{- }6[/tex]

Step 4 : Transposing 8 to right hand side :

[tex] \longmapsto \: x = \frac{\cancel{6}}{\cancel{8}} [/tex]

Step 5 : Cancelling 6/8 to their simplest form :

[tex] \longmapsto \: \pink{\boxed{x = \frac{3}{4} }}[/tex]

The range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

For a set of data, the range is the difference between the maximum and minimum value. It sort of gives an idea of spread of the data.

For this case, we're given that:

Perimeter of a rectangle = 2(length + width)

Let 'l' denotes length, and 'w' denotes width, then we get:

[tex]Perimeter \leq 4\\2(l+w) \leq 4\\2(1.5 + w) \leq 4\\\\\text{Dividing both the sides by 2}\\\\1.5 + w \leq 2\\\\\text{Subtracting 1.5 from both the sides so as to get 'w' on one side}\\\\w \leq 0.5[/tex]

Now since the lowest value of width of a frame can be zero only, therefore, we get:

[tex]0 \leq w \leq 0.5[/tex]

Thus, the range of values 'w' can assume is: 0.5 - 0 = 0.5

Thus, the range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

Method 1

Apply Difference of Two Squares Formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]

Given  [tex]x^2-16=0[/tex]

Rewrite 16 as 4²

Therefore, [tex]a^2=x^2[/tex] and [tex]b^2=4^2[/tex]

[tex]\implies a = \sqrt{x^2}=x[/tex]

[tex]\implies b=\sqrt{4^2} =4[/tex]

[tex]\implies x^2-16^2=(x+4)(x-4)[/tex]

[tex]\implies (x+4)(x-4)=0[/tex]

[tex]\implies (x+4)=0 \implies x=-4[/tex]

[tex]\implies (x-4)=0 \implies x=4[/tex]

Method 2

Given equation:

[tex]x^2-16=0[/tex]

Add 16 to both sides:

[tex]\implies x^2-16+16=0 + 16[/tex]

[tex]\implies x^2=16[/tex]

Square root both sides:

[tex]\implies \sqrt{x^2}=\sqrt{16}[/tex]

[tex]\implies x=\pm4[/tex]

Therefore, x = -4, x = 4
