Answers
we are given
m∠3 = 120° and m∠12 = 80°
we will check all
Calculation of m∠1:
we can see that angles 1 and 3 are linear
so, their sum must be 180
m∠1+m∠3 = 180°
now, we can plug values
m∠1+ 120°= 180°
m∠1=60°
Calculation of m∠13:
we know that
angles 12 and 13 are alternate angles
so, they must be equal
m∠13=m∠12 = 80°
m∠13= 80°
Calculation of m∠6:
we know that
angles 3 and 6 are alternate angles
so, they must be equal
m∠3=m∠6 = 120°
m∠6= 120°
Calculation of m∠5:
we know that
angles 1 and 5 are corresponding angles
so, they must be equal
m∠1=m∠5 = 60°
m∠5= 60°
Calculation of m∠10:
we can see that angles 10 and 12 are linear
so, their sum must be 180
m∠10+m∠12 = 180°
now, we can plug values
m∠10+ 80°= 180°
m∠10=100°
Calculation of m∠14:
we know that
angles 10 and 14 are corresponding angles

Usain Bolt set world records for the 100-m and 200-m dashes with impressive maximum speeds and accelerations.
Usain Bolt of Jamaica set the world record for the men's 100-m dash in the 2008 Olympic Games in Beijing. He accelerated for 3.00 s to reach his maximum speed and maintained it for the race. Calculating his maximum speed and acceleration involves understanding his performance data.
For the 100-m dash, Bolt's maximum speed was approximately 12.19 m/s and his acceleration was 2.63 m/s². In the 200-m dash, his maximum speed using the same assumptions was 10.36 m/s. This insight into Bolt's remarkable athleticism showcases his exceptional speed and acceleration capabilities on the track.
Tom and Sonya were comparing their answers on a math problem. It was an order of operations problem, and they each had a different answer. Tom had an answer of 11, and Sonya had an answer of 104. Which student correctly solved the order of operations problem given by the teacher?
(5^2 +6)–(7•4)+8
Answers
The order of operations is PEMDAS or parenthesis, exponents, multiplication, division, addition subtraction.
So 5^2 is 25 + 6 is 31
7*4 is 28
31 - 28 = 3
and 3 + 8 is 11
Tom was right
Hope this helps!
Seeing that it's an order of operations problem, we can use our standard format of computing, PEMDAS. It stands for:
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction
When we compute these problems, we must do it in this order. Therefore, when we do this problem, we start within the parentheses.
(5^2 +6)–(7•4)+8
Inside the parentheses, we have an exponent. Since it's second, we compute it first.
(25 +6)–(7•4)+8
Next, we can simplify the multiplication problem in the other set of parentheses.
(25 +6)–(28)+8
Simplify first parentheses:
31 - 28 + 8
Subtract
3 + 8 =
11
Notice how we subtracted first. That's because when we do PEMDAS, addition, and subtraction, along with multiplication and division, are on the same level- so you can do them in any order. This doesn't go for anything else though unless it's obviously commutative.
Hope this helps!

In a normal distribution, the mean is ____ it's mean and mode
Answers
Final answer:
In a normal distribution, the mean, median, and mode are all the same, since it is symmetric around the mean. The standard deviation affects the shape of the distribution, and the empirical rule states that most values lie within two standard deviations of the mean. Differences in symmetry may cause the mean, median, and mode to diverge, with the mean being most affected by skewness.
Explanation:
In a normal distribution, the mean is equal to the median and mode, by definition. This is because the normal distribution, which is also known as the Gaussian distribution, is symmetrically shaped like a bell curve around the mean (μ). The mean indicates the center of the distribution and the point of symmetry, while the median divides the data such that half of the values are above it and half are below. The mode is the most frequently occurring value in the data set, and in a perfect normal distribution, it coincides with the mean and median.
The standard deviation (σ) is a measure of the spread of the distribution. If the standard deviation is increased, the curve becomes wider and flatter, while a decrease in σ makes the distribution steeper and narrower. Additionally, the location of μ on the X-axis can shift the entire graph to the left or right, but the shape of the graph remains the same. The empirical rule helps us understand that approximately 95% of values lie within two standard deviations from the mean.
Drawing from the collaborative exercise provided, by recording the heights and creating histograms with smooth bell-shaped curves, one can calculate the mean and identify how characteristics such as skewness affect the mean, median, and mode, especially in non-symmetric distributions. In these cases, the mean can be influenced by the direction of the skew more than the median, pulling it towards the tail of the distribution.

Answer:
0.3y + y / z
For
y = 10
z = 5
the result is 5.
When [tex]\( y = 10 \) and \( z = 5 \)[/tex], [tex]\( 0.3y + \frac{y}{z} \) equals \( 5 \)[/tex].
Step 1 :To evaluate the expression [tex]\(0.3y + \frac{y}{z}\) when \(y = 10\) and \(z = 5\)[/tex], follow these steps:
1. Substitute the given values of [tex]\(y\) and \(z\)[/tex] into the expression:
[tex]\[0.3 \times 10 + \frac{10}{5}\][/tex]
2. Calculate each term separately:
- [tex]\(0.3 \times 10 = 3\)[/tex]
- [tex]\(\frac{10}{5} = 2\)[/tex]
3. Add the results:
[tex]\[3 + 2 = 5\][/tex]
So, when [tex]\(y = 10\) and \(z = 5\)[/tex], the expression [tex]\(0.3y + \frac{y}{z}\) equals \(5\).[/tex]
Step 2 :1. Multiply 0.3 by 10:
[tex]\[0.3 \times 10 = 3\][/tex]
2. Divide 10 by 5:
[tex]\[\frac{10}{5} = 2\][/tex]
3. Add the results:
[tex]\[3 + 2 = 5\][/tex]
Thus, when [tex]\(y = 10\) and \(z = 5\)[/tex], the expression [tex]\(0.3y + \frac{y}{z}\) equals \(5\).[/tex]

What are the roots of the equation?
x^2+24=−11x
Enter your answers in the boxes.
Answers
x=-3 and x=-8.
Explanation:
We can first write this in standard form, ax²+bx+c=0. To do this, we will add 11x to both sides:
x²+24+11x=-11x+11x
x²+11x+24=0.
Now we can factor this. Look for factors of c, 24, that sum to b, 11. Factors of 24 are:
1 and 24 (sum 25)
2 and 12 (sum 14)
3 and 8 (sum 11)
4 and 6 (sum 10).
The factors we need are 3 and 8, since they sum to 11. This gives us factored form:
(x+3)(x+8)=0.
Using the zero product property, we know that in order to have a product of 0, one or both of the factors must be 0. This means we have:
x+3=0 or x+8=0.
Solving the first equation:
x+3-3=0-3
x=-3.
Solving the second equation:
x+8-8=0-8
x=-8.
Answer:
[tex]x_1 = -8[/tex]
[tex]x_2 = -3[/tex]
Step-by-step explanation:
Given the equation:
[tex]x^2+24 = -11x[/tex]
Add 11x to both sides we have;
[tex]x^2+11x+24 = 0[/tex]
Split the middle terms we have;
⇒[tex]x^2+8x+3x+24 = 0[/tex]
⇒[tex]x(x+8)+3(x+8)= 0[/tex]
⇒[tex](x+8)(x+3)= 0[/tex]
By zero product property we have;
x+8 = 0 and x+3= 0
⇒x = -8 and x = -3
Therefore, the roots of the given equations are:
[tex]x_1 = -8[/tex]
[tex]x_2 = -3[/tex]

Standard Form of a Circle.
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
To use the standard form of a circle, we need to know the center of the circle and the radius of the circle. Our center is at (-2, -3), which is (h, k). Our radius is half of the diameter, which the diameter is 8 so 8 / 2 = 4. So we have a radius of 4.
In our Standard Form of a Circle, the h = -2 and the k = -3 and the 4 = r
Now we can turn this into the general form of a circle.
Insert our point (-2, -3) and our radius of 4 into the standard form of a circle equation and transform it into the general form.
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
[tex](x - (-2))^2 + (y - (-3))^2 =4^2[/tex]
[tex](x + 2)^2 + (y + 3)^2 = 4^2[/tex]
[tex](x + 2)^2 + (y + 3)^2 = 16[/tex]
Expand (x + 2)^2
[tex]x^2 + 4x + 4 + (y + 3)^2 = 16[/tex]
Expand (y + 3)^2
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 = 16[/tex]
Move the 16 over to the left side by adding a - 16
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 16 - 16[/tex]
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 0[/tex]
Now arrange and combine like terms
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 0[/tex]
Gathering all constant values
[tex]x^2 + 4x + y^2 + 6y + 9 -16 + 4 = 0[/tex]
Gathering all x and y values
[tex]x^2 + 4x + y^2 + 6y + 9 - 16 + 4 = 0[/tex]
[tex]x^2 + y^2 + 4x + 6y + 9 - 16 + 4 = 0[/tex]
Combining all constant terms
[tex]x^2 + y^2 + 4x + 6y + 9 - 16 + 4 = 0[/tex]
[tex]x^2 + y^2 + 4x + 6y - 3 = 0[/tex]
There is nothing else to combine so we have the general form of a circle, which is [tex]x^2 + y^2 + 4x + 6y - 3 = 0[/tex] so the answer is C

[tex]x^2 + y^2 + 4x + 6y - 3 = 0[/tex]

Equation of a circleThe equation of the circle that represents the general form of a circle with a center at (–2, –3) and a radius of 4 units can be found by substituting the values in the equation of a circle:
[tex](x-h)^2+(y-k)^2 = R^2[/tex]
Substituting the values,
[tex][x-(-2)]^2+[y-(-3)]^2 = 4^2\\\\ (x+2)^2+(y+3)^2 = 16[/tex]
[tex](x+2)^2+(y+3)^2 = 16\\\\ (x^2 + 4 + 4x)+(y^2+9+6y) = 16\\\\ x^2 + 4 + 4x+y^2+9+6y = 16\\\\ x^2 + 4x+y^2+6y = 16-4-9\\\\ x^2 + 4x+y^2+6y = 3\\\\ x^2 + 4x+y^2+6y -3 = 0[/tex]
Therefore, the equation which will be in the above form will be the equation we want. As we can see the above equation is similar to option c.

What is the length of one leg of the triangle
Answers
Answer:
Step-by-step explanation:
The length measure of the second leg of the right-angle triangle is 12 units.
What is the measure of the missing leg length of the triangle?Given the parameter:
Hypotenuse = 15 units
Length of leg1 = 9 units
Length of leg2 = x
To determine the measure of the missing side length of the right triangle, we use the Pythagoras theorem.
It is expressed as:
( hypotenuse )² = ( leg 1 )² + ( leg 2 )²
Plug in the given values:
( 15 )² = ( 9 )² + ( leg 2 )²
Simplifying, we get:
225 = 81 + ( leg 2 )²
( leg 2 )² = 225 - 81
( leg 2 )² = 144
Take the square roots:
leg 2 = √144
leg 2 = 12 units
Therefore, the second leg measures 12 units.

Answers
Final answer:
Cecil should pay $14.29 for his golf hats.
Explanation:
To determine what Cecil should pay for his golf hats, we need to calculate the cost price and apply the 40% markup. Let's assume the cost price is 'x'. Since Cecil needs a 40% markup on cost, the selling price will be 140% of the cost.
To find the selling price, we can use the equation: 140% of 'x' = $20. Solving this equation, we get: x = $20 / 1.4 = $14.29.
Therefore, Cecil should pay $14.29 for his golf hats.
