Help me please. I did the rest I just need f thank you
Answer:
None of these
Step-by-step explanation:
Corresponding, alternate interior, and same side interior angles only occur in a set of parallel lines. In figure f, none of the lines are parallel. Straight angles are defined as angles that make up one side of the line, or 180 degrees, and as the picture clearly shows, this is not the case.

Paul purchases an antique circular frame for his mom for Mother's Day. The diameter of the frame is 18 cm. What is the area of the bowl
Answer:
254.34cm²
Step-by-step explanation:
the bowl is shaped is shaped in the form of a circle
Area of the bowl is equal to the area of a circle
area of a circle = πr²
π = 3.14
r = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 9² = 254.34cm²
What is the value of x?
Enter your answer in the box.
Answer:
x=12
Step-by-step explanation:
Both Angles together have a 180 degrees, set your formula up as
180=(10x-20)+(6x+8)
180=10x+6x-20+8
180+20-8=16x
192=16x
192/16=x
12=x
Answer:
x = 12
Step-by-step explanation:
The two angles form a straight line so they add to 180
10x-20 + 6x+8 = 180
Combine like terms
16x -12 = 180
Add 12 to each side
16x-12+12=180+12
16x = 192
Divide each side by 16
16x/16 =192/16
x = 12

The width of a rectangle, in feet, is represented by (3x + 2). The length of the rectangle, in feet, is represented by (5x + 4). Find the perimeter of the rectangle
Answer:
2*(5x+4) + 2*(3x+2)
= 10x + 8 + 6x + 2
= 16x + 10
The perimeter of the rectangle, in feet, is represented by (16x + 10)
Answer:
(16x + 12) ft
Step-by-step explanation:
Perimeter of the rectangle = 5x + 4 + 3x + 2 + 5x + 4 + 3x + 2
Perimeter of the rectangle = (16x + 12) ft

This
year the team won 20 games. What
is the
percent increase in the number of
games the team won from last year to this
year?
Answer:
they increased by 25%
Step-by-step explanation:
16/4 = 4. 16+4 = 20. Because of this, the number of wins increased by 4, or 1/4 of last year's wins. this means it increased by 25%.

Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
[tex]A=\pi r^2\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta[/tex] is the central angle or measure of intercepted arc.
Putting [tex]r=4,\ \theta =135^\circ[/tex] in the above formula, we get
[tex]A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}[/tex]
[tex]A=\pi \times 16\times \dfrac{3}{8}[/tex]
[tex]A=\pi \times 2\times 3[/tex]
[tex]A=6\pi [/tex]
Therefore, the exact area of the given sector is [tex]6\pi [/tex] square meters.

At a coffee shop, the first 100 customers'
orders were as follows.

Medium
Large
Hot
5
48
22
8
12

Cold
What is the probability that a customer ordered
a cold drink given that he or she ordered a large?
Rounded to the nearest percent, [? ]%
The probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.
Let us find the individual probabilities.
P(Large | Cold) = 5/25 = 0.2 (out of 25 cold drinks, 5 were large)
P(Cold) = (8+12+5)/100 = 0.25 (out of 100 orders, 25 were cold)
P(Large) = (22+5)/100 = 0.27 (out of 100 orders, 27 were large)
Now we can plug these values into Bayes' theorem:
P(Cold | Large) = 0.2 × 0.25 / 0.27
P(Cold | Large) = 0.1852
Therefore, the probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.

Construct the 95% confidence interval estimate of the mean VAS score for patients given the magnet treatment. Find the Standard error and critical value. construct the 95% confidence interval estimate of the mean VAS score for patients given the sham treatment. You may do the shortcut.
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error

special right triangles (radical answers)
Answer:
x = [tex]\sqrt{6}[/tex]
Step-by-step explanation:
Since the given triangle is equilateral the all 3 sides would be:
[tex]\sqrt{6} +\sqrt{6}[/tex] or [tex]\sqrt{12}[/tex]. Now we know that the base of the right triangle is [tex]\sqrt{6}[/tex] and the hypotenuse is [tex]\sqrt{12}[/tex]. Therefore we can say;
A² + B² = C²
([tex]\sqrt{6}[/tex])² + x² = ([tex]\sqrt{12}[/tex])²
6 + x² = 12
x² = 12 - 6
x² = 6
x = [tex]\sqrt{6}[/tex]
Therefore; x = [tex]\sqrt{6}[/tex] is the length of x, in simplest radical form.

how do i find the area for number 4?
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
The bottom rectangle has area of 4*8 = 32 cm^2The top rectangle has area of 3*3 = 9 cm^2The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:
Area = Length x Width
A = L x W
To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them

Which system of equations could you use to determine where the paths intersect?
=B) y = 0.8x and y = -0.12x2 + 20
Step-by-step explanation:

Based on the graph, the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.Read more on vertex here: brainly.com/question/525947
