So, to find this answer, we want to use Pythagorean Theorem!
The formula for this theorem is: a²+b²=c².
· It's important to note that c² is always your hypotenuse, while a and b are your legs.
So, all we need to do is (1) plug in our values, (2) square them, (3) isolate them, and (4) find the square root of our final number!
--------------------------------------------------------------------------------------------------------------
14²+14²=c²
14² = 196
We want to isolate our C, but we can't do that with the squared symbol, so in order to remove a squared symbol, we need to square root both sides.
196 = c²
√196 = 14
C = 14

The shoes are on sale for 39.99. If they were marked down 20%, what was the original price?
Final answer:
The original price comes out to $49.99 when rounded to the nearest cent.
Explanation:
To determine the original price of an item that has been marked down by 20%, we need to understand that the current price represents 80% of the original price (100% - 20% = 80%).
Therefore, the sale price is 80% of the original price. If the shoes were on sale for $39.99, we can set up an equation where the original price is represented by x, and the sale price is 80% of x, or 0.80x.
The equation would be 0.80x = $39.99.
To find the original price, we divide both sides by 0.80:
x = $39.99 / 0.80
x = $49.9875
Therefore, the original price of the shoes was $49.99 when rounded to the nearest cent.

An unbalanced die is manufactured so that there is a 20% chance of rolling a “six." The die is rolled 6
times. What is the probability of rolling at least 4 sixes?
Answer:
Probability of rolling at least 4 sixes is 0.01696.
Step-by-step explanation:
We are given that an unbalanced die is manufactured so that there is a 20% chance of rolling a “six." The die is rolled 6 times.
The above situation can be represented through binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number trials (samples) taken = 6 trials
r = number of success = at least 4
p = probability of success which in our question is probability of
rolling a “six", i.e; p = 0.20
Let X = Number of sixes on a die
So, X ~ Binom(n = 6, p = 0.20)
Now, Probability of rolling at least 4 sixes is given by = P(X [tex]\geq[/tex] 4)
P(X [tex]\geq[/tex] 4) = P(X = 4) + P(X = 5) + P(X = 6)
= [tex]\binom{6}{4} \times 0.20^{4} \times (1-0.20)^{6-4}+\binom{6}{5} \times 0.20^{5} \times (1-0.20)^{6-5}+\binom{6}{6} \times 0.20^{6} \times (1-0.20)^{6-6}[/tex]
= [tex]15 \times 0.20^{4} \times 0.80^{2}+6 \times 0.20^{5} \times 0.80^{1}+1 \times 0.20^{6} \times 0.80^{0}[/tex]
= 0.0154 + 0.00154 + 0.000064
= 0.01696
Therefore, probability of rolling at least 4 sixes is 0.01696.
Using the binomial distribution, it is found that there is a 0.0086 = 0.86% probability of rolling at least 4 sixes.
For each roll, there are only two possible outcomes, either it is a six, or it is not. The result of a roll is independent of any other rolls, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
The die is rolled 6 times, hence [tex]n = 6[/tex].There are six sides on the dice, one of which is 6, hence [tex]p = \frac{1}{6} = 0.1667[/tex].The probability is:
[tex]P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{6,4}.(0.1667)^{4}.(0.8333)^{2} = 0.0080[/tex]
[tex]P(X = 5) = C_{6,5}.(0.1667)^{5}.(0.8333)^{1} = 0.0006[/tex]
[tex]P(X = 6) = C_{6,6}.(0.1667)^{6}.(0.8333)^{0} \approx 0[/tex]
Then:
[tex]P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6) = 0.0080 + 0.0006 + 0 = 0.0086[/tex]
0.0086 = 0.86% probability of rolling at least 4 sixes.

Write a quadratic function f whose zeros are 6 ad 5
The quadratic function f whose zeros are 6 and 5 is represented by the formula f(x) = (x - 6)(x - 5). This formula utilizes the fact that the zeros of a quadratic function, also known as the roots, are the x-values for which the function equals zero.
Explanation:To write a quadratic function f whose zeros are 6 and 5, we first identify the zeros. These zeros are the roots of the equation, meaning the points at which the curve of the function hits the x-axis.
A quadratic function is in the form f(x) = a(x - p)(x - q), where p and q are the zeros. Therefore, if the zeros are 6 and 5, our function becomes f(x) = a(x - 6)(x - 5), with 'a' being any real number. If we take 'a' as 1 (for simplicity), the function becomes f(x) = (x - 6)(x - 5).
So the quadratic function with zeros 6 and 5 is f(x) = (x - 6)(x - 5).

In a taste test, 50 participants are randomly given a beverage to sample.
There are 20 samples of Drink A, 10 samples of Drink B, 10 samples of Drink
C, and 10 samples of Drink D. Write the probability of a participant NOT
sampling Drink A.
Answer:
20 out of the 50 participants are assigned to consume Drink A.
However, it is asking us the probability that a participant did NOT consume Drink A, so there are 30 participants that consumed another drink.
The probability is 30/50, or 60%, that a participant did not sample Drink A.
Answer:
3/5
Step-by-step explanation:
of the 50 participants 20 of them will get drink A. This probability is 20/50 which simplified is 2/5. The other 30 participants will get drinks B, C, or D. As a fraction this is equal to 30/50 or 3/5. Therefore the probability of a participant not sampling drink A is 3/5.

Which value is closets to 8 11/20 A)8 B)8 1/2 C)8 3/4 D) 9
Final answer:
The value 8 3/4 (option C) is closest to 8 11/20 because it has the smallest difference when compared to the other options after converting 11/20 to its decimal form.
Explanation:
The value closest to 8 11/20 is 8 3/4 (option C). To determine which value is closest, convert 11/20 to its decimal equivalent by dividing 11 by 20, which is 0.55. When added to 8, this gives us 8.55. Now let's compare the options: Option A (8) is 0.55 away, option B (8 1/2) equals 8.5 and is 0.05 away, option C (8 3/4) equals 8.75 and is 0.20 away, and option D (9) is 0.45 away. Thus, 8 3/4 is the closest value to 8 11/20 since it has the smallest difference.

A snow plough has a 3.2m blade set at an angle of 30 degrees How wide a path will the snow plough clear
Answer:
1.6m
Step-by-step explanation:
The length of the blade is 3.2m
The angle which the blade makes is 30°
Assuming the path of the blade and the length it covers is a right-angled triangle,
The length of the blade is the hypothenus while the path at which it clears is the opposite of the triangle.
See attached document for better illustration.
Using SOHCAHTOA,
Sinθ = opposite / hypothenus
opposite = x
hypothenus = 3.2
θ = 30°
Sin30 = x / 3.2
X = 3.2sin30
X = 3.2 × 0.5
X = 1.6m
The path which the snow plough clears is 1.6m
Final answer:
Using trigonometry, the width of the path that a snow plough with a 3.2m blade set at a 30 degree angle will clear is approximately 2.77 meters wide.
Explanation:
To determine the width of the path that a snow plough will clear, we can make use of trigonometry. Given that the blade of the snow plough is 3.2 meters wide and is set at an angle of 30 degrees, we can calculate the width of the path cleared (w) by using the following formula derived from the cosine of the angle:
w = blade width × cos(angle)
Therefore, the width of the path cleared is:
w = 3.2 m × cos(30°)
To solve for w, we need to know the cosine of 30 degrees, which is √3/2. So the calculation will be:
w = 3.2 m × (√3/2)
After calculating this:
w = 3.2 m × 0.866
w = 2.7712 m
Therefore, the snow plough will clear a path approximately 2.77 meters wide.

The distance between the points $(x,21)$ and $(4,7)$ is $10 \sqrt{2}.$ Find the sum of all possible values of $x.$
Answer:
the sum of all possible values of x is: 2+6 = 8
Step-by-step explanation:
Assume the two points in your question are:
A [tex](x_{1},y_{1})[/tex] = (x,21)B [tex](x_{2}, y_{2})[/tex] = (4,7)=> The distance between the points A(x,21) and B(4,7) is [tex]10\sqrt{2}[/tex]
As we know, the distance of two points can be determined by this formula:
[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
Apply this formula in this situation to find all possible values of x, we have:
[tex]\sqrt{(4-x)^{2} + (7-21)^{2} }[/tex] = [tex]\frac{10}{\sqrt{2} }[/tex]
<=> [tex](4-x)^{2} + 196 = 200[/tex]
<=> [tex](4-x)^{2} = 4[/tex]
<=> (4-x) = 2 or (4-x) = -2
<=> x = 2 or x = 6
=> the sum of all possible values of x is: 2+6 = 8

Step-by-step explanation:
y increases by 10 while x increases by 9
The average rate of change of a function over an interval is calculated by finding the difference in the function values at the endpoints and dividing it by the difference in the x-values.
Explanation:The average rate of change of a function over an interval is calculated by finding the difference in the function values at the endpoints of the interval and dividing it by the difference in the x-values.
In this case, we are given the interval 0 ≤ x ≤ 9. We need to find the difference in the function values of g at x = 0 and x = 9, and then divide it by the difference in the x-values, which is 9 - 0 = 9.
So, the average rate of change of g over the interval 0 ≤ x ≤ 9 is (g(9) - g(0)) / (9 - 0).
