find the angle YWX.
Answer:
34
Step-by-step explanation:
9x-28 = 5x-8
4x = 20
x = 5
5 times x(aka 5) minus 8=17
9 times x(aka 5) minus 28=17
17+17
ywx=34
The value of the angle YWX will be 34.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that the two angles ZWY and ZWX are ( 9x - 28 ) and ( 5x - 8 ) respectively,
The angle will be calculated as:-
9x-28 = 5x-8
4x = 20
x = 5
The angle YWX will be the sum of the angles YWZ and XWZ.
YWX = ( 9 x 5) -28 + ( 5 x 5 ) - 8
YWX = 45 - 28 + 25 - 8
YWX = 17 + 17
YWX = 34
Hence, the measure of the angle YWX is 34.

In the 2017 national Youth Risk Behavior Survey, 16.5% of high school students had ridden with a driver who had been drinking alcohol within the previous month. This data came from an SRS of 14,500 students. what is the mean and standard deviation
Answer:
[tex]Mean = 2392.5[/tex]
[tex]SD = 44.70[/tex]
Step-by-step explanation:
Given
[tex]Students = 14500[/tex]
[tex]p = 16.5\%[/tex]
Solving (a): The mean
Mean is calculated as thus:
[tex]Mean = np[/tex]
[tex]Mean = 16.5\% * 14500[/tex]
Convert % to decimal
[tex]Mean = 0.165 * 14500[/tex]
[tex]Mean = 2392.5[/tex]
Solving (b): The Standard Deviation
Standard deviation (SD) is calculated as thus:
[tex]SD = \sqrt{np(1-p)}[/tex]
[tex]SD = \sqrt{14500 * 16.5\%(1-16.5\%)}[/tex]
Convert % to decimal
[tex]SD = \sqrt{14500 * 0.165 * (1-0.165)}[/tex]
[tex]SD = \sqrt{14500 * 0.165 * 0.835}[/tex]
[tex]SD = \sqrt{1997.7375}[/tex]
[tex]SD = 44.6960568731[/tex]
[tex]SD = 44.70[/tex]

Answer:
Perimeter: 16x + 16
Area: 40x + 15
Step-by-step explanation:
Remember, the perimeter is the sum of all the sides of a figure, it can be found by adding up all the sides. The area is the space within the figure, in the case of a quadrilateral can be found by multiplying the length by the width. Finally, in a rectangle, the opposite sides are congruent, parallel, and intersect in 90degree (right) angles.
Using this,
1. Find the perimeter
Since opposite sides are congruent, there will be two sides with a measure of ( 8x + 3 ), and two sides with the measure of 5. Hence the sum of all the sides would be
8x + 3 + 8x + 3 + 5 + 5
Add them together,
16x + 16.
The perimeter of the figure is 16x + 16
2. Find the area,
To find the area of a rectangle, multiply the length by the width.;
( 8x + 3 ) * 5
Distribute:
40x + 15
The area of the figure is 40x + 15
V'W'X'Y' has vertices V^' (-3,2),W^' (5,1),X^' (0,4),and Y'(-2,0). If V'W'X'Y' is the image of VWXY rotated 90° around the origin. What are the coordinates of VWXY (the pre-image).
Given:
V'W'X'Y' has vertices V'(-3,2), W'(5,1), X'(0,4) and Y'(-2,0).
V'W'X'Y' is the image of VWXY rotated 90° around the origin.
To find:
The coordinates of VWXY (the pre-image).
Solution:
V'W'X'Y' is the image of VWXY rotated 90° around the origin. It means, the figure VWXY is rotated 90° counterclockwise around the origin.
So, if we rotate V'W'X'Y' 90° clockwise around the origin, then we get the original figure VWXY.
If a figure rotated 90° clockwise around the origin, then
[tex](x,y)\to (y,-x)[/tex]
[tex]V'(-3,2)\to V(2,3)[/tex]
[tex]W'(5,1)\to W(1,-5)[/tex]
[tex]X'(0,4)\to X(4,0)[/tex]
[tex]Y'(-2,0)\to Y(0,2)[/tex]
Therefore, the coordinates of preimage are V(2,3), W(1,-5), X(4,0) and Y(0,2).

TY
i need help with these 9 questions they’re pretty simple
Answer:
1. n = 4
2. n = -29
3. n = -28
4. n = -48
5. n = -22
6. n = 97
7. n = 220
8. n = -18
9. n = 36
Step-by-step explanation:
1. -n = -4
Multiply both by -1 to get n = 4
2. 12 + n = -17
Subtract 12 from both sides of the equation to get n = -29
3. -n/14 = 2
Multiply by 14 on both sides of the equation to get -n = 28
Multiply -1 on both sides of the equation to get n = -28
4. -42 = n + 6
Subtract 6 from both sides of the equation to get -48 = n or n = -48
5. -4n = 88
Divide -4 on both sides of the equation to get n = -22
6. n + -3 = 94
Add 3 to both sides of the equation to get n = 97
7. 11 = -n/-20
Multiply by -20 on both sides of the equation to get -220 = -n or -n = -220
Multiply -1 on both sides of the equation to get n = 220
8. -108 = 6n
Divide by 6 on both sides of the equation to get -18 = n or n = -28
9. 67 = 31 + n
Subtract 31 from both sides of the equation to get 36 = n or n = 36
